--> B. Deploy a corporate Read-Only Domain Controller to the branch location. - On Microsoft Servers, a domain controller (DC) is a server computer that responds to security authentication requests (logging in, checking permissions, etc.) within a Windows domain. A domain is a concept introduced in Windows NT whereby a user may be granted access to a number of computer resources with the use of a single username and password combination. One DC serves as the primary domain controller (PDC). Others, if they exist, are usually a backup domain controller (BDC). The PDC is typically designated as the "first". The "User Manager for Domains" is a utility for maintaining user/group information. It uses the domain security database on the primary controller. The PDC has the master copy of the user accounts database which it can access and modify. The BDC computers have a copy of this database, but these copies are read-only. The PDC will replicate its account database to the BDCs on a regular basis. The BDCs exist in order to provide a backup to the PDC, and can also be used to authenticate users logging on to the network. If a PDC should fail, one of the BDCs can then be promoted to take its place. The PDC will usually be the first domain controller that was created unless it was replaced by a promoted BDC. Windows Server can be one of three kinds: Active Directory "domain controllers" (ones that provide identity and authentication), Active Directory "member servers" (ones that provide complimentary services such as file repositories and schema) and Windows Workgroup "stand-alone servers". The term "Active Directory Server" is sometimes used by Microsoft as synonymous to "Domain Controller" but the term is discouraged.

Encourage cybersecurity analysts to review open-source intelligence products and threat database to generate new IDS rules based on those sources -visit or "drive by" a web page, without stopping to click or accept any software, and the malicious code can download in the background to your device. A drive-by download refers to the unintentional download of a virus or malicious software (malware) onto your computer or mobile device. A drive-by download will usually take advantage of (or "exploit") a browser, app, or operating system that is out of date and has a security flaw. This initial code that is downloaded is often very small (so you probably wouldn't notice it), since its job is often simply to contact another computer where it can pull down the rest of the code on to your smartphone, tablet, or computer. Often, a web page will contain several different types of malicious code, in hopes that one of them will match a weakness on your computer.

Which of the following would have allowed the security team to use historical information to protect against the second attack? A. Key risk indicators B. Lessons learned C. Recovery point objectives D. Tabletop exercise

--> B. Lessons learned - A key risk indicator (KRI) is a measure used in management to indicate how risky an activity is. Key risk indicators are metrics used by organizations to provide an early signal of increasing risk exposures in various areas of the enterprise. It differs from a key performance indicator (KPI) in that the latter is meant as a measure of how well something is being done while the former is an indicator of the possibility of future adverse impact. KRI give an early warning to identify potential event that may harm continuity of the activity/project. - The recovery point objective (RPO) is the age of files that must be recovered from backup storage for normal operations to resume if a computer, system, or network goes down as a result of a hardware, program, or communications failure. - Tabletop exercises are discussion-based sessions where team members meet in an informal, classroom setting to discuss their roles during an emergency and their responses to a particular emergency situation. A facilitator guides participants through a discussion of one or more scenarios.

(40) Management is reviewing the results of a recent risk assessment of the organization's policies and procedures.

--> B. NX/XN bit - The NX bit (no-execute) is a technology used in CPUs to segregate areas of memory for use by either storage of processor instructions (code) or for storage of data. An operating system with support for the NX bit may mark certain areas of memory as non-executable. The processor will then refuse to execute any code residing in these areas of memory. - TrustZone is a set of security extensions added to ARMv6 processors and greater, such as ARM11, CortexA8, CortexA9 and CortexA15. To improve security, these ARM processors can run a secure operating system (secure OS) and a normal operating system (normal OS) at the same time from a single core. - Secure copy protocol (SCP) is a means of securely transferring computer files between a local host and a remote host or between two remote hosts. It is based on the Secure Shell (SSH) protocol. "SCP" commonly refers to both the Secure Copy Protocol and the program itself.

--> B. OLA - A blanket purchase agreement (BPA) is a simplified acquisition method that government agencies use to fill anticipated repetitive needs for supplies or services. Essentially, BPAs are like "charge accounts" set up with trusted suppliers. - An operational-level agreement (OLA) defines the interdependent relationships in support of a service-level agreement (SLA).[1] The agreement describes the responsibilities of each internal support group toward other support groups, including the process and timeframe for delivery of their services. The objective of the OLA is to present a clear, concise and measurable description of the service provider's internal support relationships. OLA is sometimes expanded to other phrases but they all have the same meaning: Organisational-level agreement, Operating-level agreement, or Operations-level agreement. - A master service agreement (MSA) is a contract reached between parties, in which the parties agree to most of the terms that will govern future transactions or future agreements. A master service agreement allows the involved parties to more quickly negotiate future transactions or agreements, because they can rely on the strong foundation of the master agreement for future business, so that the same terms need not be repetitively negotiated, and you only need to negotiate terms specific to the latest deal. - A memorandum of understanding (MOU) is a type of agreement between two or more parties. It expresses a convergence of will between the parties, indicating an intended common line of action.

(Choose two.) A. Port security B. Route protection C. NAC D. HIPS E. NIDS

--> B. Route protection, C. NAC -Route protection is primarily maintained by means of IPSec. IPSec protects networks by securing IP packets with encryption and enforcement of trusted communication. IPSec is the most widely used standard for protecting IP datagrams. Because IPSec can be applied below the application layer, it can be used by any or all applciations and is transparent to end users. IPSec can be configured to communicate in tunnel and transport modes. -Port Security helps secure the network by preventing unknown devices from forwarding packets. When a link goes down, all dynamically locked addresses are freed. The port security feature offers the following benefits: You can limit the number of MAC addresses on a given port. Packets that have a matching MAC address (secure packets) are forwarded; all other packets (unsecure packets) are restricted.You can enable port security on a per port basis. Port security implements two traffic filtering methods, dynamic locking and static locking. These methods can be used concurrently. Dynamic locking. You can specify the maximum number of MAC addresses that can be learned on a port. The maximum number of MAC addresses is platform dependent and is given in the software Release Notes. After the limit is reached, additional MAC addresses are not learned. Only frames with an allowable source MAC addresses are forwarded.Note: If you want to set a specific MAC address for a port, set the dynamic entries to 0, then allow only packets with a MAC address matching the MAC address in the static list.Dynamically locked addresses can be converted to statically locked addresses. Dynamically locked MAC addresses are aged out if another packet with that address is not seen within the age-out time. You can set the time out value. Dynamically locked MAC addresses are eligible to be learned by another port. Static MAC addresses are not eligible for aging. Static locking. You can manually specify a list of static MAC addresses for a port. Dynamically locked addresses can be converted to statically locked addresses. -Because NAC represents an emerging category of security products its definition is both evolving and controversial. The overarching goals of the concept can be distilled as: Mitigation of non-zero-day attacks; Authorization, Authentication and Accounting of network connections; Encryption of traffic to the wireless and wired network using protocols for 802.1X such as EAP-TLS, EAP-PEAP or EAP-MSCHAP; Role-based controls of user, device, application or security posture post authentication; Automation with other tools to define network role based on other information such as known vulnerabilities, jailbreak status etc; The main benefit of NAC solutions is to prevent end-stations that lack antivirus, patches, or host intrusion prevention software from accessing the network and placing other computers at risk of cross-contamination of computer worms. Policy enforcement. NAC solutions allow network operators to define policies, such as the types of computers or roles of users allowed to access areas of the network, and enforce them in switches, routers, and network middleboxes. Identity and access management - where conventional IP networks enforce access policies in terms of IP addresses, NAC environments attempt to do so based on authenticated user identities, at least for user end-stations such as laptops and desktop computers.

Which of the following should the company implement NEXT? A. Multicloud solution B. Single-tenancy private cloud C. Hybrid cloud solution D. Cloud access security broker

--> D. Cloud access security broker - Multicloud is the use of multiple cloud computing and storage services in a single heterogeneous architecture. This is also known as a Polynimbus cloud strategy. This also refers to the distribution of cloud assets, software, applications, etc. across several cloud-hosting environments. With a typical multicloud architecture utilizing two or more public clouds as well as multiple private clouds, a multicloud environment aims to eliminate the reliance on any single cloud provider. It differs from hybrid cloud in that it refers to multiple cloud services rather than multiple deployment modes (public, private, legacy). Also, in a multicloud environment, synchronization between different vendors is not essential to complete a computation process, unlike parallel computing or distributed computing environments. - Single Tenant - A single instance of the software and supporting infrastructure serve a single customer. With single tenancy, each customer has his or her own independent database and instance of the software. Essentially, there is no sharing happening with this option. Multi-Tenant - Multi-tenancy means that a single instance of the software and its supporting infrastructure serves multiple customers. Each customer shares the software application and also shares a single database. Each tenant's data is isolated and remains invisible to other tenants. - Hybrid cloud is a cloud computing environment that uses a mix of on-premises, private cloud and third-party, public cloud services with orchestration between the two platforms. By allowing workloads to move between private and public clouds as computing needs and costs change, hybrid cloud gives businesses greater flexibility and more data deployment options.Establishing a hybrid cloud requires the availability of: A public infrastructure as a service (IaaS) platform, such as Amazon Web Services, Microsoft Azure or Google Cloud Platform; The construction of a private cloud, either on premises or through a hosted private cloud provider; And adequate wide area network (WAN) connectivity between those two environments. - A cloud access security broker (CASB) is on-premises or cloud based software that sits between cloud service users and cloud applications, and monitors all activity and enforces security policies. A CASB can offer a variety of services, including but not limited to monitoring user activity, warning administrators about potentially hazardous actions, enforcing security policy compliance, and automatically preventing malware.

(46) A security administrator wants to allow external organizations to cryptographically validate the company's domain name in email messages sent by employees. Which of the following should the security administrator implement? A. SPF B. S/MIME C. TLS D. DKIM

--> D. DKIM - Sender Policy Framework (SPF) is an anti-spam approach in which the Internet domain of an e-mail sender can be authenticated for that sender, thereby discouraging spam mailers, who routinely disguise the origin of their e-mail - Secure/Multipurpose Internet Mail Extensions (S/MIME) is a widely accepted method (or more precisely, a protocol) for sending digitally signed and encrypted messages. S/MIME allows you to encrypt emails and digitally sign them. When you use S/MIME with an email message, it helps the people who receive that message to be certain that what they see in their inbox is the exact message that started with the sender. It will also help people who receive messages to be certain that the message came from the specific sender and not from someone pretending to be the sender. To do this, S/MIME provides for cryptographic security services such as authentication, message integrity, and non-repudiation of origin (using digital signatures). It also helps enhance privacy and data security (using encryption) for electronic messaging. - Transport Layer Security (TLS) is a cryptographic protocol that provides end-to-end communications security over networks and is widely used for internet communications and online transactions. It is an IETF standard intended to prevent eavesdropping, tampering and message forgery. - DomainKeys Identified Mail (DKIM) is an email authentication method designed to detect forged sender addresses in emails. DKIM allows the receiver to check that an email claimed to have come from a specific domain was indeed authorized by the owner of that domain. It achieves this by affixing a digital signature, linked to a domain name, to each outgoing email message. The recipient system can verify this by looking up the sender's public key published in the DNS. A valid signature also guarantees that some parts of the email (possibly including attachments) have not been modified since the signature was affixed. Usually, DKIM signatures are not visible to end-users, and are affixed or verified by the infrastructure rather than the message's authors and recipients.

(81) A network engineer is attempting to design-in resiliency characteristics for an enterprise network's VPN services.

Subscribe to a managed service provider capable of supporting the mitigation of advanced DDoS attacks on the enterprise's pool of VPN concentrators. C. Distribute the VPN concentrators across multiple systems at different physical sites to ensure some backup services are available in the event of primary site loss. D. Employ a second VPN layer concurrently where the other layer's cryptographic implementation is sourced from a different vendor.

--> D. Employ a second VPN layer concurrently where the other layer's cryptographic implementation is sourced from a different vendor. (Could be wrong; investigate)

(48) A SaaS-based email service provider often receives reports from legitimate customers that their IP netblocks are on blacklists and they cannot send email. The SaaS has confirmed that affected customers typically have IP addresses within broader network ranges and some abusive customers within the same IP ranges may have performed spam campaigns. Which of the following actions should the SaaS provider perform to minimize legitimate customer impact? A. Inform the customer that the service provider does not have any control over third-party blacklist entries. The customer should reach out to the blacklist operator directly B. Perform a takedown of any customer accounts that have entries on email blacklists because this is a strong indicator of hostile behavior C. Work with the legal department and threaten legal action against the blacklist operator if the netblocks are not removed because this is affecting legitimate traffic D.

(12) The Chief Information Security Officer (CISO) at a large organization has been reviewing some security-related incidents at the organization and comparing them to current industry trends. The desktop security engineer feels that the use of USB storage devices on office computers has contributed to the frequency of security incidents. The CISO knows the acceptable use policy prohibits the use of USB storage devices. Every user receives a popup warning about this policy upon login. The SIEM system produces a report of USB violations on a monthly basis; yet violations continue to occur. Which of the following preventative controls would MOST effectively mitigate the logical risks associated with the use of USB storage devices? A. Revise the corporate policy to include possible termination as a result of violations B. Increase the frequency and distribution of the USB violations report C. Deploy PKI to add non-repudiation to login sessions so offenders cannot deny the offense D. Implement group policy objects

--> D. Implement group policy objects - Group policy is a feature of Microsoft Windows Active Directory that adds additional controls to user and computer accounts. Group policies provide centralized management and operating systems configurations of user's computing environments. Group policies are another method of securing user's computers from infiltration and data breaches. A Group Policy Object is a collection of settings systems administrators create with the Microsoft Management Console (MMC) Group Policy Editor. The GPO can be associated with one or more of the Active Directory containers, such as sites, domains, or organizational units (OUs). Active Directory applies GPOs in the following predictable and logical order: Local policies, Site policies, Domain policies, and OU policies. Group policies can disable outdated protocols like SSLv2, prevent users from making changes to local group policies, and much more. There are several advantages to implementing GPOs outside of security. Ease of management: Setting up new users on the network used to be a long and tedious process. Pre-existing GPOs apply a standardized environment to each new user and computer that joins your domain which saves many hours of configurations. One-stop administration: Sysadmins can deploy patches, software, and other updates via GPO. Password policy enforcement: Passwords can be easily brute-forced if they aren't changed regularly, contain simple words, or are short. GPOs establish length, reuse rules, and other requirements for passwords to keep your network safe. Folder redirections: Do you want users to keep important company files on a centralized and monitored storage system? Use a folder redirection GPO to redirect their user folder to your NAS.

Which of the following technologies is MOST likely being used to provide access to the third company? A. LDAP B. WAYF C. OpenID D. RADIUS E. SAML

--> D. RADIUS - The Lightweight Directory Access Protocol (LDAP) is an open, vendor-neutral, industry standard application protocol for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network. Directory services play an important role in developing intranet and Internet applications by allowing the sharing of information about users, systems, networks, services, and applications throughout the network. As examples, directory services may provide any organized set of records, often with a hierarchical structure, such as a corporate email directory. - The goal of a "Where Are You From" (WAYF) service is to guide a user to his or her Identity Provider. Some documentation also calls this the "Identity Provider Discovery" service. Basically, all the WAYF has to accomplish, is to present the user a list of Identity Providers and redirect the user's web browser to the selected Identity Provider (IdP) or back to the Service Provider (the web application that the user is trying to access). Some WAYFs have additional features which enhance the user's ease-of use. This includes several methods of remembering or guessing the user's Identity Provider selection. Usually by storing a persistent cookie which indicates the user's previous choice of Identity Provider. - OpenID is an open standard and decentralized authentication protocol. Promoted by the non-profit OpenID Foundation, it allows users to be authenticated by co-operating sites (known as relying parties, or RP) using a third-party service, eliminating the need for webmasters to provide their own ad hoc login systems, and allowing users to log into multiple unrelated websites without having to have a separate identity and password for each. Users create accounts by selecting an OpenID identity provider, and then use those accounts to sign onto any website that accepts OpenID authentication. Several large organizations either issue or accept OpenIDs on their websites according to the OpenID Foundation. - Remote Authentication Dial-In User Service (RADIUS) is a networking protocol, operating on port 1812 that provides centralized Authentication, Authorization, and Accounting (AAA or Triple A) management for users who connect and use a network service. Because of the broad support and the ubiquitous nature of the RADIUS protocol, it is often used by Internet service providers (ISPs) and enterprises to manage access to the Internet or internal networks, wireless networks, and integrated e-mail services. These networks may incorporate modems, digital subscriber line (DSL), access points, virtual private networks (VPNs), network ports, web servers, etc. RADIUS is a client/server protocol that runs in the application layer, and can use either TCP or UDP as transport. Network access servers, the gateways that control access to a network, usually contain a RADIUS client component that communicates with the RADIUS server. RADIUS is often the back-end of choice for 802.1X authentication as well. The RADIUS server is usually a background process running on a UNIX or Microsoft Windows server. - Security Assertion Markup Language (SAML) is an open standard for exchanging authentication and authorization data between parties, in particular, between an identity provider and a service provider. SAML is an XML-based markup language for security assertions (statements that service providers use to make access-control decisions). SAML is also: A set of XML-based protocol messages A set of protocol message bindings A set of profiles (utilizing all of the above) The single most important use case that SAML addresses is web browser single sign-on (SSO). Single sign-on is relatively easy to accomplish within a security domain (using cookies, for example) but extending SSO across security domains is more difficult and resulted in the proliferation of non-interoperable proprietary technologies. The SAML Web Browser SSO profile was specified and standardized to promote interoperability. - The well known TCP port for SSL is 636 while TLS is negotiated within a plain TCP connection on port 389. - Port 5800 and 5900 are opened by the VNC system allowing remote multi-platform console access. - TCP port 1433 is the default port for SQL Server. This port is also the official Internet Assigned Number Authority (IANA) socket number for SQL Server. Client systems use TCP 1433 to connect to the database engine; SQL Server Management Studio (SSMS) uses the port to manage SQL Server instances across the network.

A private IaaS F. A private PaaS

--> B. A public PaaS - Public clouds are the most common way of deploying cloud computing. The cloud resources (like servers and storage) are owned and operated by a third-party cloud service provider and delivered over the Internet. Microsoft Azure is an example of a public cloud. With a public cloud, all hardware, software, and other supporting infrastructure is owned and managed by the cloud provider. In a public cloud, you share the same hardware, storage, and network devices with other organizations or cloud "tenants." You access services and manage your account using a web browser. Public cloud deployments are frequently used to provide web-based email, online office applications, storage, and testing and development environments. (1) Advantages of public clouds: Lower costs—no need to purchase hardware or software, and you pay only for the service you use. (2) No maintenance—your service provider provides the maintenance. (3) Near-unlimited scalability—on-demand resources are available to meet your business needs. (4) High reliability with a vast network of servers ensuring against failure. - A private cloud consists of computing resources used exclusively by one business or organization. The private cloud can be physically located at your organization's on-site datacenter, or it can be hosted by a third-party service provider. But in a private cloud, the services and infrastructure are always maintained on a private network and the hardware and software are dedicated solely to your organization. In this way, a private cloud can make it easier for an organization to customize its resources to meet specific IT requirements. Private clouds are often used by government agencies, financial institutions, any other mid- to large-size organizations with business-critical operations seeking enhanced control over their environment. Advantages of a private clouds: (1) More flexibility—your organization can customize its cloud environment to meet specific business needs. (2) Improved security—resources are not shared with others, so higher levels of control and security are possible. (3) High scalability—private clouds still afford the scalability and efficiency of a public cloud. - Hybrid clouds combine on-premises infrastructure, or private clouds, with public clouds so organizations can reap the advantages of both. In a hybrid cloud, data and applications can move between private and public clouds for greater flexibility and more deployment options. For instance, you can use the public cloud for high-volume, lower-security needs such as web-based email, and the private cloud (or other on-premises infrastructure) for sensitive, business-critical operations like financial reporting. In a hybrid cloud, "cloud bursting" is also an option. This is when an application or resource runs in the private cloud until there is a spike in demand (such as seasonal event like online shopping or tax filing), at which point the organization can "burst through" to the public cloud to tap into additional computing resources. Advantages of hybrid clouds: (1) Control-your organization can maintain a private infrastructure for sensitive assets. (2) Flexibility—you can take advantage of additional resources in the public cloud when you need them. (3) Cost-effectiveness—with the ability to scale to the public cloud, you pay for extra computing power only when needed. (4) Ease—transitioning to the cloud doesn't have to be overwhelming because you can migrate gradually—phasing in workloads over time. - Software as a service (SaaS) allows users to connect to and use cloud-based apps over the Internet. Common examples are email, calendaring and office tools (such as Microsoft Office 365). SaaS provides a complete software solution which you purchase on a pay-as-you-go basis from a cloud service provider. You rent the use of an app for your organisation and your users connect to it over the Internet, usually with a web browser. All of the underlying infrastructure, middleware, app software and app data are located in the service provider's data center. The service provider manages the hardware and software and with the appropriate service agreement, will ensure the availability and the security of the app and your data as well. SaaS allows your organisation to get quickly up and running with an app at minimal upfront cost. Advantages of SaaS: (1) Gain access to sophisticated applications. To provide SaaS apps to users, you don't need to purchase, install, update or maintain any hardware, middleware or software. SaaS makes even sophisticated enterprise applications, such as ERP and CRM, affordable for organisations that lack the resources to buy, deploy and manage the required infrastructure and software themselves. (2) Pay only for what you use. You also save money because the SaaS service automatically scales up and down according to the level of usage. (3) Use free client software. Users can run most SaaS apps directly from their web browser without needing to download and install any software, although some apps require plugins. This means that you don't need to purchase and install special software for your users. (4) Mobilise your workforce easily. SaaS makes it easy to "mobilise" your workforce because users can access SaaS apps and data from any Internet-connected computer or mobile device. You don't need to worry about developing apps to run on different types of computers and devices because the service provider has already done so. In addition, you don't need to bring special expertise onboard to manage the security issues inherent in mobile computing. A carefully chosen service provider will ensure the security of your data, regardless of the type of device consuming it. (5) Access app data from anywhere. With data stored in the cloud, users can access their information from any Internet-connected computer or mobile device. And when app data is stored in the cloud, no data is lost if a user's computer or device fails. - Platform as a service (PaaS) is a complete development and deployment environment in the cloud, with resources that enable you to deliver everything from simple cloud-based apps to sophisticated, cloud-enabled enterprise applications. You purchase the resources you need from a cloud service provider on a pay-as-you-go basis and access them over a secure Internet connection. Like IaaS, PaaS includes infrastructure—servers, storage, and networking—but also middleware, development tools, business intelligence (BI) services, database management systems, and more. PaaS is designed to support the complete web application lifecycle: building, testing, deploying, managing, and updating. PaaS allows you to avoid the expense and complexity of buying and managing software licenses, the underlying application infrastructure and middleware or the development tools and other resources. You manage the applications and services you develop, and the cloud service provider typically manages everything else. Advantages of PaaS: (1) Cut coding time. PaaS development tools can cut the time it takes to code new apps with pre-coded application components built into the platform, such as workflow, directory services, security features, search, and so on. (2) Add development capabilities without adding staff. Platform as a Service components can give your development team new capabilities without your needing to add staff having the required skills. (3) Develop for multiple platforms—including mobile—more easily. Some service providers give you development options for multiple platforms, such as computers, mobile devices, and browsers making cross-platform apps quicker and easier to develop. (4) Use sophisticated tools affordably. A pay-as-you-go model makes it possible for individuals or organizations to use sophisticated development software and business intelligence and analytics tools that they could not afford to purchase outright. (5) Support geographically distributed development teams. Because the development environment is accessed over the Internet, development teams can work together on projects even when team members are in remote locations. (6) Efficiently manage the application lifecycle. PaaS provides all of the capabilities that you need to support the complete web application lifecycle: building, testing, deploying, managing, and updating within the same integrated environment. - Infrastructure as a service (IaaS) is an instant computing infrastructure, provisioned and managed over the internet. It's one of the four types of cloud services, along with software as a service (SaaS), platform as a service (PaaS), and serverless. IaaS quickly scales up and down with demand, letting you pay only for what you use. It helps you avoid the expense and complexity of buying and managing your own physical servers and other datacenter infrastructure. Each resource is offered as a separate service component, and you only need to rent a particular one for as long as you need it. A cloud computing service provider, such as Azure, manages the infrastructure, while you purchase, install, configure, and manage your own software—operating systems, middleware, and applications. Advantages of IaaS: (1) Eliminates capital expense and reduces ongoing cost. IaaS sidesteps the upfront expense of setting up and managing an on-site data centre, making it an economical option for start-ups and businesses testing new ideas. (2) Improves business continuity and disaster recovery. Achieving high availability, business continuity and disaster recovery is expensive, as it requires a significant amount of technology and staff. But with the right service level agreement (SLA) in place, IaaS can reduce this cost, meaning you can access applications and data as usual during a disaster or outage. (3) Innovate rapidly. As soon as you've decided to launch a new product or initiative, the necessary computing infrastructure can be ready in minutes or hours, rather than the days or weeks (and sometimes months) it could take to set up internally. (4) Respond more quickly to shifting business conditions. IaaS enables you to quickly scale up resources to accommodate spikes in demand for your application - during the holidays, for example - then scale resources back down again when activity decreases to save money. (5) Focus on your core business. IaaS frees up your team to focus on your organisation's core business rather than on IT infrastructure. (6) Increase stability, reliability and supportability. With IaaS, there's no need to maintain and upgrade software and hardware or troubleshoot equipment problems. With the appropriate agreement in place, the service provider ensures that your infrastructure is reliable and meets SLAs. (7) Better security. With the appropriate service agreement, a cloud service provider can provide security for your applications and data that may be better than what you can attain in-house. (8) Gets new apps to users faster. Because you don't need to first set up the infrastructure before you can develop and deliver apps, you can get them to users faster with IaaS.

(32) One of the objectives of a bank is to instill a security awareness culture. Which of the following are techniques that could help to achieve this? (Choose two.) A. Blue teaming B. Phishing simulations C. Lunch-and-learn D. Random audits E. Continuous monitoring F. Separation of duties

(10) A network engineer wants to deploy user-based authentication across the company's wired and wireless infrastructure at layer 2 of the OSI model. Company policies require that users be centrally managed and authenticated and that each user's network access be controlled based on the user's role within the company. Additionally, the central authentication system must support hierarchical trust and the ability to natively authenticate mobile devices and workstations. Which of the following are needed to implement these requirements? (Select TWO). A. SAML B. WAYF C. LDAP D. RADIUS E. Shibboleth F. PKI

--> C. LDAP, D. RADIUS - Security Assertion Markup Language (SAML) is an open standard for exchanging authentication and authorization data between parties, in particular, between an identity provider and a service provider. SAML is an XML-based markup language for security assertions (statements that service providers use to make access-control decisions). SAML is also: A set of XML-based protocol messages, a set of protocol message bindings, and set of profiles (utilizing all mentioned). The single most important use case that SAML addresses is web browser single sign-on (SSO). Single sign-on is relatively easy to accomplish within a security domain (using cookies, for example) but extending SSO across security domains is more difficult and resulted in the proliferation of non-interoperable proprietary technologies. The SAML Web Browser SSO profile was specified and standardized to promote interoperability. (For comparison, the more recent OpenID Connect protocol is an alternative approach to web browser SSO. - Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. The design goals of XML emphasize simplicity, generality, and usability across the Internet. It is a textual data format with strong support via Unicode for different human languages. Although the design of XML focuses on documents, the language is widely used for the representation of arbitrary data structures such as those used in web services. Several schema systems exist to aid in the definition of XML-based languages, while programmers have developed many application programming interfaces (APIs) to aid the processing of XML data. - The goal of a "Where Are You From" (WAYF) service is to guide a user to his or her Identity Provider, aka the "Identity Provider Discovery" service. Basically, all the WAYF has to accomplish is to present the user a list of Identity Providers and redirect the user's web browser to the selected Identity Provider (IdP) or back to the Service Provider (the web application that the user is trying to access). Some WAYFs have additional features which enhance the user's ease-of use. This includes several methods of remembering or guessing the user's Identity Provider selection. Usually by storing a persistent cookie which indicates the user's previous choice of Identity Provider. - The Lightweight Directory Access Protocol (LDAP) is an open, vendor-neutral, industry standard application protocol for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network. Directory services play an important role in developing intranet and Internet applications by allowing the sharing of information about users, systems, networks, services, and applications throughout the network. As examples, directory services may provide any organized set of records, often with a hierarchical structure, such as a corporate email directory. Similarly, a telephone directory is a list of subscribers with an address and a phone number. A common use of LDAP is to provide a central place to store usernames and passwords. This allows many different applications and services to connect to the LDAP server to validate users. LDAP is based on a simpler subset of the standards contained within the X.500 standard. Because of this relationship, LDAP is sometimes called X.500-lite. Protocol Overview: A client starts an LDAP session by connecting to an LDAP server, called a Directory System Agent (DSA), by default on TCP and UDP port 389, or on port 636 for LDAPS (LDAP over SSL, see below).The client then sends an operation request to the server, and the server sends responses in return. With some exceptions, the client does not need to wait for a response before sending the next request, and the server may send the responses in any order. All information is transmitted using Basic Encoding Rules (BER). The client may request the following operations: StartTLS - use the LDAPv3 Transport Layer Security (TLS) extension for a secure connection Bind - authenticate and specify LDAP protocol version Search - search for and/or retrieve directory entries Compare - test if a named entry contains a given attribute value Add a new entry Delete an entry Modify an entry Modify Distinguished Name (DN) - move or rename an entry Abandon - abort a previous request Extended Operation - generic operation used to define other operations Unbind - close the connection (not the inverse of Bind) In addition the server may send "Unsolicited Notifications" that are not responses to any request, e.g. before the connection is timed out. A common alternative method of securing LDAP communication is using an SSL tunnel. The default port for LDAP over SSL is 636. - Remote Authentication Dial-In User Service (RADIUS) is a networking protocol, operating on port 1812 that provides centralized Authentication, Authorization, and Accounting (AAA or Triple A) management for users who connect and use a network service. Because of the broad support and the ubiquitous nature of the RADIUS protocol, it is often used by Internet service providers (ISPs) and enterprises to manage access to the Internet or internal networks, wireless networks, and integrated e-mail services. These networks may incorporate modems, digital subscriber line (DSL), access points, virtual private networks (VPNs), network ports, web servers, etc. RADIUS is a client/server protocol that runs in the application layer, and can use either TCP or UDP as transport. Network access servers, the gateways that control access to a network, usually contain a RADIUS client component that communicates with the RADIUS server. RADIUS is often the back-end of choice for 802.1X authentication as well. The RADIUS server is usually a background process running on a UNIX or Microsoft Windows server. The user or machine sends a request to a Network Access Server (NAS) to gain access to a particular network resource using access credentials. The credentials are passed to the NAS device via the link-layer protocol—for example, Point-to-Point Protocol (PPP) in the case of many dialup or DSL providers or posted in an HTTPS secure web form. In turn, the NAS sends a RADIUS Access Request message to the RADIUS server, requesting authorization to grant access via the RADIUS protocol.This request includes access credentials, typically in the form of username and password or security certificate provided by the user. Additionally, the request may contain other information which the NAS knows about the user, such as its network address or phone number, and information regarding the user's physical point of attachment to the NAS. The RADIUS server checks that the information is correct using authentication schemes such as PAP, CHAP or EAP. The user's proof of identification is verified, along with, optionally, other information related to the request, such as the user's network address or phone number, account status, and specific network service access privileges. Historically, RADIUS servers checked the user's information against a locally stored flat file database. Modern RADIUS servers can do this, or can refer to external sources—commonly SQL, Kerberos, LDAP, or Active Directory servers—to verify the user's credentials. RADIUS Authentication and Authorization Flow: The RADIUS server then returns one of three responses to the NAS: 1) Access Reject, 2) Access Challenge, or 3) Access Accept. Access Reject: The user is unconditionally denied access to all requested network resources. Reasons may include failure to provide proof of identification or an unknown or inactive user account. Access Challenge: Requests additional information from the user such as a secondary password, PIN, token, or card. Access Challenge is also used in more complex authentication dialogs where a secure tunnel is established between the user machine and the Radius Server in a way that the access credentials are hidden from the NAS. Access Accept: The user is granted access. Once the user is authenticated, the RADIUS server will often check that the user is authorized to use the network service requested. A given user may be allowed to use a company's wireless network, but not its VPN service, for example. Again, this information may be stored locally on the RADIUS server, or may be looked up in an external source such as LDAP or Active Directory. Each of these three RADIUS responses may include a Reply-Message attribute which may give a reason for the rejection, the prompt for the challenge, or a welcome message for the accept. The text in the attribute can be passed on to the user in a return web page. Authorization attributes are conveyed to the NAS stipulating terms of access to be granted. For example, the following authorization attributes may be included in an Access-Accept: The specific IP address to be assigned to the user The address pool from which the user's IP should be chosen The maximum length of time that the user may remain connected An access list, priority queue or other restrictions on a user's access L2TP parameters VLAN parameters Quality of Service (QoS) parameters When a client is configured to use RADIUS, any user of the client presents authentication information to the client. This might be with a customizable login prompt, where the user is expected to enter their username and password. Alternatively, the user might use a link framing protocol such as the Point-to-Point Protocol (PPP), which has authentication packets which carry this information. Once the client has obtained such information, it may choose to authenticate using RADIUS. To do so, the client creates an "Access- Request" containing such Attributes as the user's name, the user's password, the ID of the client and the Port ID which the user is accessing. When a password is present, it is hidden using a method based on the RSA Message Digest Algorithm MD5. - Shibboleth is a single sign-on log-in system for computer networks and the Internet. It allows people to sign in using just one identity to various systems run by federations of different organizations or institutions. The federations are often universities or public service organizations. The Shibboleth Internet2 middleware initiative created an architecture and open-source implementation for identity management and federated identity-based authentication and authorization (or access control) infrastructure based on Security Assertion Markup Language (SAML). Federated identity allows the sharing of information about users from one security domain to the other organizations in a federation. This allows for cross-domain single sign-on and removes the need for content providers to maintain user names and passwords. Identity providers (IdPs) supply user information, while service providers (SPs) consume this information and give access to secure content. Shibboleth's access control is performed by matching attributes supplied by IdPs against rules defined by SPs. An attribute is any piece of information about a user, such as "member of this community", "Alice Smith", or "licensed under contract A". User identity is considered an attribute, and is only passed when explicitly required, which preserves user privacy. Attributes can be written in Java or pulled from directories and databases. Trust between domains is implemented using public key cryptography (often simply TLS server certificates) and metadata that describes providers. The use of information passed is controlled through agreements. Federations are often used to simplify these relationships by aggregating large numbers of providers that agree to use common rules and contracts.

Which of the following tools BEST supports the use of these definitions? A. HTTP interceptor B. Static code analyzer C. SCAP scanner D. XML fuzzer

--> D. XML fuzzer - An interceptor pattern is a software design pattern that is used when software systems or frameworks want to offer a way to change, or augment, their usual processing cycle. For example, a (simplified) typical processing sequence for a web-server is to receive a URI from the browser, map it to a file on disk, open the file and send its contents to the browser. Any of these steps could be replaced or changed, e.g. by replacing the way URIs are mapped to filenames, or by inserting a new step which processes the files contents. - Static program analysis is the analysis of computer software that is performed without actually executing programs, in contrast with dynamic analysis, which is analysis performed on programs while they are executing. - A Security Content Automation Protocol (SCAP) scanner is a tool that compares a target computer or application's configuration and/or patch level against that of the SCAP content baseline. The tool will note any deviations and produce a report. Some SCAP scanners also have the ability to correct the target computer and bring it into compliance with the standard baseline. - An XML fuzzer takes a valid XML as input and generates a set of modified, potentially invalid, XMLs based on the input.
