As the lead for a software development team, you must establish secure development requirements. Which of the following best practices must be included for secure software development? (Choose all that apply.) A) Use only HTTP POST requests for sending web authentication credentials B) Session IDs should be included in the URL for web applications C) If a TLS connection fails, the connection should default back to standard HTTP D) Input sanitization should validate all characters against a whitelist E) Input validation should be performed only on the server-side to limit client buffer overflows
A) Use only HTTP POST requests for sending web authentication credentials D) Input sanitization should validate all characters against a whitelist #To do : input sanitization to validate all characters against a whitelist and using only HTTP POST requests for sending web authentication credentials. #Not to do: (for secure software development practices) Session IDs should not be included in the URL for web applications, as this will reduce the complexity in performing session hijacking attacks. You should not use standard HTTP over TLS, because the web traffic is no longer encrypted. NOTE: Input validation is for preventing an attacker at multiple layers from performing an injection attack. (Input validation should be performed on both client-side and server-side systems)
You need to restrict access to resources on your company's Windows Active Directory domain. Which criteria can be used to restrict access to resources? A) all of these choices B) location C) transaction type D) groups E) roles F) time of day
A) all of these choices #Regardless of the criteria used, access administration can be simplified by grouping objects and subjects. Access control lists (ACLs) can be used to assign users, groups, or roles access to a particular resource. If you implement time of day restrictions with ACLs, security is improved. #Groups are created to incorporate users that need the same access permissions into one common entity. When these users need access to a resource, the permission is granted to the entire group. Using groups simplifies access control administration.
Your company has deployed a firewall that includes two network interfaces. Which firewall architecture has been deployed? A) dual-homed firewall B) screened subnet C) bastion host D) screened host
A) dual-homed firewall #A dual-homed firewall has two network interfaces. One interface connects to the public network, usually the Internet. The other interface connects to the private network.

Your company has decided to deploy a new wireless network at a branch office. This branch office is located in a busy commercial district. Management has asked you to fully assess the external vulnerabilities of the wireless network before it is deployed. Which three conditions should you assess? (Choose three.) A) Number of users B) Antenna placement C) Speed of connection D) Access point strength E) Captive portals F) Antenna type
B) Antenna placement D) Access point strength F) Antenna type #Antenna type (such as the use of directional versus omnidirectional antennas) plays an important role in protecting a wireless network. Using a directional antenna can limit the area that is covered by the antenna. #Antenna placement will also have an effect on the vulnerabilities of a wireless system. Antennas should be placed as far away from exterior walls as possible. Otherwise, the signal will go outside the building. This allows anyone outside the building to attach to your network. That is why RADIUS and other technologies are required for wireless networks. #The strength of the access points should be adjusted to a level that is just strong enough for the operation of the network, but not so strong that signals escape to the outside of the building. You should reduce power levels for better security to ensure that the signal does not extend beyond its needed range. #The number of users and the speed of the connection will not cause external vulnerabilities to a wireless system. The number of user addresses is, however, a cause of external vulnerabilities.

You are very concerned about these obvious administrative accounts. What security control should you implement? A) Recertification B) File system security C) Standard naming conventions D) Account maintenance
C) Standard naming conventions #Creating a standard naming convention would resolve the issue of obvious account names. Account names should not identify job roles. Recertification is the process of examining a user's permissions and determining if they still need access to what was previously granted. For example, if an employee were transferred from the Chicago, IL office to the Charlotte, NC, it would be reasonable to revoke the user's Chicago permissions.
You are setting up a complex PKI where clients might have to get a certificate from somewhere other than their own CA. What should you include in the implementation to define the relationships between the various CAs? A) Stapling B) Pinning C) Trust model D) Key escrow
C) Trust model #A trust model defines how various certificate authorities (CAs) trust each other. Ultimately, the trust model also defines how the client of a given CA would trust the certificate from another CA. #Certificate chaining refers to the trust relationships between CAs and helps determine which certificate has the highest level trust. For example, if you get a certificate from "A," and "A" trusts the root certificate, the highest level trust is the root certificate.
Which integrity strategy is used to ensure that application code has not been tampered with since it was checked in by a developer? A) Unit testing B) Integration testing C) Versioning control D) Monitoring control
C) Versioning control #In all stages of application development, version control is essential. Version control allows you to manage changes to files over time and store these revisions in a database. Changes one developer made should not necessarily be wiped out by the changes another developer presents, especially if it was meant to be only a temporary modification for testing purposes. Any integration errors should be rolled back, so that they do not cause the entire application to fail. The resolution is to have a version control system that manages those changes across the development team and process stages.
What is a honeypot? A) a skeleton of the network without any data or functionality B) a disruptive strategy that allows you to maximize the effectiveness of your decoy C) a computer system that draws in malicious actors to determine how attackers break into systems D) an enterprise management software designed to mediate access to cloud services
C) a computer system that draws in malicious actors to determine how attackers break into systems #A honeypot is a decoy computer system that draws in malicious actors to determine how attackers break into networks and systems. This gives organization's the ability to learn the attacker's techniques and how they access resources they shouldn't.
An IT technician has been assigned to install a new embedded firewall. What statement best describes this type of firewall? A) a component that is added to a hardware firewall B) a black box device C) a firewall that is integrated into a router D) a firewall that is installed on a server operating system
C) a firewall that is integrated into a router
Which policy defines the sensitivity of a company's data? A) a backup policy B) a security policy C) an information policy D) a use policy
C) an information policy #An information policy defines the sensitivity of a company's data and the proper procedures for storage, transmission, disposal, and marking of a company's data. The cornerstone practice of a company's information policy, as with all security-related policies, is to grant only the level of access that is required to allow particular individuals to fulfill their responsibilities.
You have been asked to research the encryption algorithms available and make recommendations to management about which to implement. One of the encryption algorithms that you are researching is RSA. Which type of encryption algorithm does this algorithm represent? A) asymmetric with authorization B) symmetric with authentication C) asymmetric with authentication D) symmetric with digital signature
C) asymmetric with authentication #RSA is used as the worldwide de facto standard for digital signatures. RSA is a public key algorithm that provides both encryption and authentication. It relies on the hacker's inability to factor large prime numbers.
You have just discovered that an application that your company purchased is intentionally embedded with software code that allows a developer to bypass the regular access and authentication mechanisms. Which software code is being described? A) pseudo-flaw B) multipart virus C) debugging hooks D) logic bomb
C) debugging hooks #A debugging or maintenance hook is software code that is intentionally embedded in the software during its development process to allow the developer to bypass the regular access and authentication mechanisms. These hooks can pose a threat to the security of the software and can be exploited if any maintenance hook is not removed before the software goes into production and an intruder is able to find the maintenance hook.
A hacker has used a design flaw in an application to obtain unauthorized access to the application. Which type of attack has occurred? A) maintenance hook B) buffer overflow C) escalation of privileges D) backdoor
C) escalation of privileges #An escalation of privileges attack occurs when an attacker has used a design flaw in an application to obtain unauthorized access to the application. There are two types of privilege escalation: vertical and horizontal.
Which access control principle ensures that a particular role has more than one person trained to perform its duties? A) separation of duties B) least privilege C) job rotation D) implicit deny
C) job rotation #Job rotation ensures that a particular role has more than one person trained to perform its duties. Personnel should be periodically rotated, particularly in important positions. Job rotation and separation of duties also help to prevent collusion.
You have recently been hired as a security administrator for your company. In the security documentation, it mentions that message authentication code (MAC) is implemented. What does this ensure? A) message confidentiality B) message replay C) message integrity D) message availability
C) message integrity #Message authentication code (MAC), which is also referred to as message integrity code (MIC), ensures the integrity of messages. MAC adds authentication capability to a one-way hashing function. MAC does not ensure message replay. It provides protection against message replay attacks. #MAC cannot ensure the availability of the data or the system. Nor does it provide message confidentiality or message replay.
You have been hired as a security administrator by your company. You have recommended that the organization implement a biometric system to control access to the server room. You recommend implementing a system that identifies an employee by the pattern of blood vessels at the back of the employee's eyes. Which biometric system are you recommending? A) iris scan B) eye recognition C) retina scan D) facial scan
C) retina scan #A retina scan is a biometric system that examines the unique pattern of the blood vessels at the back of an individual's eye. In a retina scan, a beam is projected inside the eye to capture the pattern and compare it with the reference records of the individual. The employee is authenticated only if a match is found. Retina scans provide better accuracy than iris scans.
You are configuring a wireless guest network, but you need to prevent guests from accessing the corporate intranet, while informing them of the acceptable use policy. Which access method should you use? A) WPA2-Personal B) WPS C) WPA2-Enterprise D) Captive portal
D) Captive portal #A captive portal is used to display a webpage to the user upon connection. It may or may not require authentication and may also post permissible activities. #WPA2 Enterprise is a version of EAP that uses AES encryption and requires the use of a RADIUS server. #WPA2 Personal is a version of EAP that uses either TKIP or AES encryption and can use passwords.
Management asks you to implement an encryption standard that uses a single 56-bit encryption key to encrypt 64-bit blocks of data. Which encryption standard should you implement? A) TDES B) SSL C) Blowfish D) DES
D) DES #(DES) is a block cipher encryption standard that uses a single 56-bit encryption key to encrypt 64-bit blocks of data. It is a symmetric or private key encryption algorithm. #Triple Data Encryption Standard (TDES) uses multiple DES encryption and decryption processes to create an encryption scheme that is stronger than DES. #Blowfish is a private key encryption algorithm, optimized for use on 32-bit processors, which supports encryption keys with a maximum length of 448 bits. Secure Sockets Layer (SSL) supports an encryption key length of 40 bits or 128 bits.

D) IPv4 #The version of addressing used by the packet is IPv4. The version is specified explicitly in the header as the first four bits. The first four bits of an IP header identifies its version. Version 6 is represented in binary as 0110 while version 4 is 0100. The source and destination addresses are also in the dotted quad format associated with IPv4.
As your organization's security officer, you are currently completing audits to ensure that your security settings meet the established baselines. In which phase of the security management life cycle are you engaged? A) Implement B) Plan and Organize C) Monitor and Evaluate D) Operate and Maintain
D) Operate and Maintain #You are engaged in the Operate and Maintain phase of the security management life cycle. This phase includes the following components: #Ensure that all baselines are met. #Complete internal and external audits. #Complete tasks outlined in the blueprints. #Manage service level agreements as outlined in the blueprints. #Completing audits is not part of any of the other phases.
What is the goal when you passively test security controls? A) Interfering with business operations B) Exploiting weaknesses C) Infiltrating the network D) Probing for weaknesses
D) Probing for weaknesses #When you passively test security controls, you are performing a vulnerability scan to identify weakness, but not exploiting those weaknesses. When you are scanning to identify a vulnerability (or several vulnerabilities), you are primarily looking for common misconfigurations and/or a lack of security controls. These misconfigurations or a lack of controls can lead to exploiting the identified weakness, interfere with business operations, and cause infiltration of the network.
Which general mechanism is used by cloud consumers to limit security exposure and running expenses? A) Container security B) Secrets management C) Resource clustering D) Resource policies
D) Resource policies #Cloud service providers can provide users with access to resources via policies. There are two ways to do this, role-based policies or resource based polices. You can use resource-based policies to provide access control where the user in a different cloud can be granted access to a resource in your account. You can also use role-based policies in which you assign a user to a role that has permission to use a resource.
You are signing up for a new account on a web site. After you enter a password, the website prompts you to provide the answers to security questions, such as the name of a childhood sweetheart or the color of your first car. What type of multifactor authentication is this? A) Something you have B) Something you do C) Something you are D) Something you know
D) Something you know #Any security question is something you know. This includes a password, a PIN, the name of a childhood sweetheart, the color of your first car, or the answer to a similar question.
Which of these options simulates a disaster and allows you to check the thoroughness of your disaster recovery plan? A) Critical business functions B) Business continuity plans C) After-action reports D) Tabletop exercises
D) Tabletop exercises #A tabletop exercise simulates a disaster and allows you to check the thoroughness of your disaster recovery plan. You should perform a document review during all exercises. Apart from a tabletop exercises, you can also perform a walkthrough, simulation, parallel testing, and cutover testing to test your disaster recovery plans. If your plan has a weakness, it is better to discover it during an exercise as opposed to discovering it during a live event. NOTE: After-action reports documents how well or how poorly the exercise went.
You are assessing whether your organization will need to comply with GDPR. Which of the following statements indicates compliance may be required? A) The organization anonymizes and generalizes any PHI of medical providers in the EEA. B) The organization consumes or provides services with an organization located in the EEA. C) The organization requires regular reporting and disposal of financial information to the EEA. D) The organization collects or stores PII from citizens located within the EEA.
D) The organization collects or stores PII from citizens located within the EEA. #GDPR is a European act that applies to any company that collects or processes personally identifiable information (PII) of the citizens of the EU. GDPR stands for the General Data Protection Regulation. The law also addresses the transfer of personal data outside of the EU and EEA areas.
Management is concerned that mobile device location information can be revealed to attackers. Which mobile device feature should you investigate? A) remote wiping B) white listing C) screen lock D) geotagging
D) geotagging #Geotagging is the process of attaching location information in the form of geographical metadata to digital media like web sites, videos, and photographs. Geotagging is a security concern because it can reveal location information. This feature embeds unseen code into a picture that records the longitude/latitude information of where the picture was taken. Geotags may also be applied to digital output and communications such as tweets or status updates on social media.
Your manager has asked you to improve network security by confining sensitive internal data traffic to computers on a specific subnet using access control lists (ACLs). On which device(s) should the ACLs be deployed? A) hubs B) firewalls C) modems D) routers
D) routers #The ACLs should be deployed on the routers. The ACLs will improve network security by confining sensitive data traffic to computers on a specific subnet. By implementing ACLs and rules, you can ensure that a secure router configuration is implemented, which will protect the routers and the subnets they manage. Another valid answer is switch. NOTE: Firewalls are typically deployed on the public network interfaces. They typically are not involved in any internal traffic. Therefore, deployment ACLs on firewalls would not confine sensitive internal data traffic to computers on a specific subnet. A firewall is classified as a rule-based access control device. Rules are configured on the firewall to allow or deny packet passage from one network to another. NOTE: hubs are typically deployed to connect hosts in a network. Active hubs provide signal regeneration, while passive hubs do not.
Management has recently become worried about DNS poisoning after reading an article about it. Which of the following BEST describes this attack? A) the practice of many computers transmitting malformed packets to the DNS server to cause the server to crash B) the practice of one computer transmitting malformed packets to the DNS server to cause the server to crash C) the practice of continually sending a DNS server synchronization messages with spoofed packets D) the practice of dispensing IP addresses and host names with the goal of traffic diversion
D) the practice of dispensing IP addresses and host names with the goal of traffic diversion #DNS poisoning is the practice of dispensing IP addresses and host names with the goal of traffic diversion. Properly configured DNS security (DNSSEC) on the DNS server can provide message validation, which, in turn, would prevent DNS poisoning.
What is the current de facto email security standard? a) PEM b) MOSS c) Hashing d) PGP
d) PGP #Pretty Good Privacy (PGP) is the current de facto e-mail security standard. The Internet Engineering Task Force (IETF) is currently developing a version of PGP known as Open-PGP.
