c. grsecurity
A network administrator needs to disable World Wide Web Publishing on all desktops in the domain. What tool will allow this task to be completed quickly with minimal effort? (A) SC.EXE (B) Group Policy (C) Services Tool (D) PowerShell
(B) Group Policy The System Services section of a GPO is more-or-less the Services applet; here you can disable any service you want, and that service will be disabled on all the systems to which the GPO applies. Services Tool is scaled through the system services section of the GPO. PowerShell and SC.EXE can be scripted but that would require more work than using Group Policy. SC.EXE is available through a resource kit and it may not be installed on all desktops in the domain.
A security minded Linux administrator is carving out separate partitions for some key logical file systems. Which of the following can be safely mounted as read only? (A) /usr (B) /home (C) /var (D) /dev
(A) /usr /usr is the place where most of the critical components of the operating system live, including system binaries, programming libraries and tools, and online documentation. You can think of this directory structure being read-only after the operating system is loaded; not many changes under /usr should occur unless the operating system is upgraded or patches are installed. /var is the place where the system keeps frequently changing data, such as log files and temporary queues for system services such as email and printing. /var is for logs that will need to be written too. /home is for users and user's will need to write to their home directories /dev is for device files including the system disk drives... some of which will need to be written to in order to function.
In which directory can executable programs that are part of the operating system be found? (A) /usr/bin (B) /dev (C) /home (D) / (E) /var/lib
(A) /usr/bin Although programs provided with the operating system end up in directories like /usr/bin and /usr/sbin, other programs can be found throughout the system. A standard convention is to put thirdparty software obtained from the Internet into the /usr/local directory. SYSV-derived systems, such as Solaris and HP-UX, often put third-party software (particularly commercial software) into /opt. Different sites may choose to use a different directory naming scheme for third-party software, however, such as /pkg or /sw.
Which of the following is an advantage of a Host Intrusion Detection System (HIDS) versus a Network Intrusion Detection System (NIDS)? (A) Ability to detect malicious traffic after it has been decrypted by the host (B) Ability to detect malicious traffic before it has been decrypted (C) Ability to listen to network traffic at the perimeter (D) Ability to decrypt network traffic
(A) Ability to detect malicious traffic after it has been decrypted by the host Notably, a Host Intrusion Detection System (HIDS) does not suffer from the same restrictions of the Network Intrusion Detection System (NIDS) when processing encrypted traffic, since the HIDS can process the traffic after it is unencrypted by the host.
Which of the following is used to protect passwords from successful pre-computation attacks? (A) Adding a random value to a password before hashing (B) Configuring account lockout after failed login attempts (C) Using a strong key with AES to encrypt passwords (D) Storing private keys separate from password values
(A) Adding a random value to a password before hashing By pre-computing hashes of possible passwords and storing the results in a database or table, matching hashes with passwords is only a matter of searching through the pre-computed tables. Adding a random value, or a salt, to a password hash makes this process much more difficult for the attacker. As pre-computation attacks are offline attacks, lockout thresholds don't apply. They are not typically associated with symmetric encryption
Which of the following is a characteristic of a cookie? (A) Can keep track of user authentication data and application session state (B) Can contain data which the web server searched for and found on the user's hard drive (C) Sent using SSL when the browser initially sets the optional secure flag (D) Editable by users when stored on the hard drive, but not when residing in memory (E) Set when the browser adds the set-cookie header to one of its requests
(A) Can keep track of user authentication data and application session state Cookies normally keep track of user authentication data and the session state of the application. They are set when the server adds the set-cookie header to one of its responses. The web server does not search a client's hard drive to find information to put into cookies, the user provides the web server with that type of information. The server can set an optional secure flag on a cookie to notify the browser to send it only using SSL. Cookies can be edited when they are on the hard drive, or in memory using a proxy like Paros or ZAP.
If a Windows user wanted to run basic Linux commands in his native environment, which of the following tools/software would he need to install? (A) Cygwin (B) GIMP (C) Ninite (D) Parallels
(A) Cygwin Cygwin consists of GNU and Open Source tools which provide Linux functionality on Windows. Ninite is a package management system for Windows. Parallels is software which provides virtualization on Macintosh computers. GIMP, or GNU Image Manipulation Program, is a program used for photo retouching, image composition, etc.
You've enabled egress traffic filtering on your organization's firewall. This action would help you prevent or eradicate which of the following incidents? (A) Four unknown computers on your network are part of a distributed. Denial of Service attack against an external website. (B) A competitor is spoofing the email address of several employees in your organization, causing those employees to receive replies to emails they never sent. (C) An unknown employee downloaded confidential information from the accounting file server to his office computer and saved the data to a thumb drive. (D) An attacker from the Ukraine used an SQL injection technique on your website's order form, which inserted an unauthorized record into your customer database.
(A) Four unknown computers on your network are part of a distributed Denial of Service attack against an external website. With egress traffic logging turned on, you can prevent or identify the four unknown computers participating in the DoS attack against an external website. Because the accounting data leakage incident occurred entirely on the organization's internal network, egress filtering would not prevent or eradicate the incident. The SQL injection attack relies on ingress (inbound) traffic from your public website, so egress (outbound) filtering would not prevent this incident. Spoofing an employee's email address occurs entirely outside of your network, so egress filtering would not prevent it.
A security analyst is preparing a vulnerability assessment against her organization's network. Which is the appropriate first step? (A) Get signed permission from the data owner (B) Configure the scanning tool for passive activity (C) Determine which hosts are in-scope for the scan (D) Get a network diagram from the administrator
(A) Get signed permission from the data owner The difference between a penetration tester and an attacker is permission! Be sure you have it. If you are just now coming up with a scanning policy in your organization, get written permission from the highest level possible in your organization (like your Chief Information Officer).
Which of the following is considered a recommended practice but not a business requirement? (A) Guideline (B) Standard (C) Baseline (D) Procedure
(A) Guideline Guidelines, unlike standards and policies, are not mandatory. Guidelines are more of a recommendation of how something should be done.
Where are most of the configuration settings for a Windows computer's hardware, operating system, applications and its user's preferences stored? (A) In the registry (B) In %SystemRoot% (C) In the Local Administrator's directory (D) At a local copy of the SAM database
(A) In the registry Virtually all configuration settings for the computer's hardware, operating system, applications and its users' preferences are stored in a special miniature database called the "registry".
Which of the following is a characteristic of a Windows NT File System (NTFS)? (A) The CHKDSK.EXE program is run automatically after a power failure or Blue Screen of Death (B) Permissions on a file or folder are not enforced when that object is accessed using FTP (C) Allow permissions take precedence over Deny permissions on a file or folder (D) The driver does not provide compression on the file system, a separate application is required
(A) The CHKDSK.EXE program is run automatically after a power failure or Blue Screen of Death NTFS uses transaction oriented processing on write operations to keep the file system in a consistent state, even after a power failure or Blue Screen of Death. In these cases, the system runs chkdsk.exe when the machine reboots. If a user is a member of two groups with conflicting permissions on a file or folder, DENY always takes precedence over ALLOW. On NTFS, file and folder permissions are always enforced by the operating system regardless of how the file is accessed. Compression is provided by the NTFS driver, no third party application is required.
What is the preferred method of setting up decoy ports on a server? (A) Use software which makes ports appear to be open but is not related to the real services (B) Enable the actual services for the decoy ports and then keep them patched and up to date (C) Set up the host to use a very small window size to manage flow control to the ports (D) Configure a host-based firewall to respond with RST packets when the decoy port is the destination port
(A) Use software which makes ports appear to be open but is not related to the real services To set up decoy ports, the systems administrator should not enable the actual services. Even if fully patched, each additional service would make the system more vulnerable. Installing software which makes the ports appear to be open but are not running the actual services is a better option. Another recommended option is to set up a gateway device which would lead an outsider to believe more ports were open. Configuring a host based firewall to send reset packets for ports would not give the illusion the ports were open. Changing the window size to manage flow control could be used to tie up an attacker's resources, but would have nothing to do with decoy ports.
You discover that the password hashes on your system are a combination of the hash of the base password, the username, the domain name and the client and server challenges. This technique for handling passwords is best described by which of the following: (A) a method used by Windows to prevent generic password precomputation attacks (B) a method used by Windows to prevent LAN MAN passwords from being broken into easily decrypted 7-character chunks (C) a method for ensuring minimum password complexity on the Linux operating system (D) a method for ensuring minimum password complexity on the macOS operating system
(A) a method used by Windows to prevent generic password precomputation attacks The inclusion of a hash of the base password with other data (such as the user and domain names) into the password hash is a technique used in NTLMv2 in Windows to defend against generic pre-computation attacks. Linux systems use a method that is similar in concept, but rather than incorporating the same information that Windows systems use (i.e. domain names, etc) Linux uses strings to "salt" the hashes. This generates unique hashes, even if two given passwords are the same. This particular method is used on Windows, not on the Mac operating system This method is used to improve the security of NTLMv2 passwords, not LAN MAN passwords.
An attacker performs a scan of all ports on a device and receives SYN/ACK responses on every port. What could be the cause of this? (A) A DNS sink hole (B) A network device with decoy ports (C) A routing loop on the device (D) A crashed system that was set to fail open
(B) A network device with decoy ports An implementation of active defense would be to set up decoy ports on network devices that instead of responding with a RST packet to ports that are not open, they response with a SYN/ACK to any requests aimed at them. This can significantly slow down an attacker as not only will their scan take longer to complete, but also because they'll have to vet each individual port to see if it actually is open.
How is a TCP/IP Packet generated as it moves down through the TCP/IP stack? (A) Application Layer -> Internet Layer -> Transport Layer -> Network Layer (B) Application Layer -> Transport Layer -> Internet Layer -> Network Layer (C) Network Layer -> Transport Layer -> Internet Layer -> Application Layer (D) Network Layer -> Internet Layer -> Transport Layer -> Application Layer
(B) Application Layer -> Transport Layer -> Internet Layer -> Network Layer As a packet is generated the packet goes from the Application Layer to the Transport Layer to the Internet Layer and finally to the Network Layer.
A pen tester found a page on the secured website she was testing that allowed her to access the site's content without asking for a login. What is the term for what she discovered? (A) One-time pad (B) Authentication bypass (C) Hidden form field (D) Brute force attack
(B) Authentication bypass An authentication bypass attack avoids accessing the authentication mechanism. An attacker might know or be able to guess the names of files or folders related to the web application that do not check for proper authentication before displaying the page. In this case, the attacker will try to type these addresses into his browser without first authenticating through the login page. Brute force attacks repeatedly try username/password combinations, changing a value with each attempt, trying to discover a set that works. One-time pad authentication schemes rely on something you have - the user is generally provided a list of onetime passwords, or a bingo card style grid they can use to create a one-time password for each authentication attempt. Hidden fields within a website are fields that are never displayed to the user.
What is the set of NTFS permissions on a folder or file called? (A) ACE (B) DACL (C) XCACL (D) SACL
(B) DACL A set of NTFS permissions on a folder or file is called a "Discretionary Access Control List (DACL)".
The perimeter firewall blocks 3389/tcp as RDP is not used within the organization. An attacker bypasses the perimeter and uses a 0- day vulnerability in RDP to pivot inside the organization. Which is the best option that would have prevented the pivot? (A) Install all RDP patches to clients on the network (B) Disable RDP in Group Policy updates (C) Use a smartcard SSO system for RDP (D) Require 128-bit RC4 for the service
(B) Disable RDP in Group Policy updates Removing unused services is the best way of ensuring they are not exploited, zero day vulnerabilities are always a possibility so patching or securing is not the best way if you do not use the service.
What could a systems administrator do to protect data in a virtualized cloud environment? (A) Build on third party application programming interfaces (B) Encrypt the snapshots of the virtual machines (C) Avoid using data fragmentation for public servers (D) Apply the same security patches to the hypervisor and virtual machines
(B) Encrypt the snapshots of the virtual machines Encrypting VM snapshots helps prevent them from being stolen or cloned. If an attacker is able to access a snapshot, he would have access to the data for that particular VM. Depending upon the security of an API, and then building upon it, increases risk and is not a sound security practice. Oftentimes in a virtual environment, the hypervisor is running a different OS than the virtual machines. In that case, and administrator could not apply the same patches to different OSes. Data fragmentation in a cloud environment is splitting a file over multiple locations so that a user (or attacker) has to get a certain number of file fragments in order to read the file. This is a security enhancement.
What defensive measure could have been taken that would have protected the confidentiality of files that were divulged by systems that were compromised by malware? (A) Monitoring for abnormal traffic flow (B) Encrypting the files locally when not in use (C) Installing file integrity monitoring software (D) Ingress filtering at the host level
(B) Encrypting the files locally when not in use Egress filtering, not ingress, may have prevented some files from getting out, but the best guarantee of preserving the confidentiality of files is to store them in encrypted form, so that even if they do get exposed, they cannot be exploited.
What alert types are a nuisance with IDS technology, but a much more significant problem with IPS technology? (A) True Negative (B) False Positive (C) True Positive (D) False Negative
(B) False Positive Where false-positive detects can be a nuisance with IDS technology, they are a much more significant problem in IPS technology.
Which of the following characterizes UDP as compared to TCP? (A) Guaranteed delivery (B) Faster (C) More complex (D) Connection oriented
(B) Faster UDP is a simpler protocol than TCP which also makes it faster. UDP is a connectionless protocol and is used when a small amount of packet loss is acceptable.
What is Advanced Application Shielding as it pertains to HIPS software? (A) Preventing an application from accessing a system resource (B) Isolating an application so it can't interact with other applications (C) Stopping malicious network traffic from accessing a listening application (D) Preventing a compromised system binary from accessing an application
(B) Isolating an application so it can't interact with other applications Advanced Application Shielding sandboxes, or isolates, a local application so it can't interact with another application. Preventing an application from accessing a system resource is system call interception. Sandboxing occurs locally, not over the network. An HIPS could identify a compromised system binary through file integrity checking, but that is not Advanced Application Shielding.
In a non-proprietary cryptosystem, which component is most likely to be compromised? (A) Ciphertext (B) Key (C) Message digest (D) Algorithm
(B) Key Good cryptography is very strong and usually hard to break, but humans are still involved in managing and controlling the key. Cryptographic keys are simply values used to initialize a particular algorithm. The important aspect of keys regarding cryptosystems is that only the key, not the algorithm, needs to be protected. That protection is provided by humans who introduce uncertainty into how effectively the key is protected. Also, the keyspace (size of the key) determines the likelihood of a successful brute force attack. Algorithms are often widely distributed and their internal workings publicly documented. The message digest - the result of a hash - by design is strong. Hash collisions, in which two files produce the same message digest using the same algorithm, are rare. By design, in good cryptography ciphertext is very difficult to crack
What is one obstacle to successfully spoofing a TCP connection? (A) Reliable authentication on the local host (B) Predicting the Initial Sequence Number (ISN) that the destination host will choose (C) Predicting the initial window size that the remote host will use for the connection (D) Getting detected by the authentication service
(B) Predicting the Initial Sequence Number (ISN) that the destination host will choose When spoofing a connection, ACKs (connection request replies) do not go back to the attacker. The ACK, however, has the ISN, a large number which uniquely identifies the connection and without which spoofing will fail. So to complete the connection, the attacker needs to somehow figure out the correct ISN. This is non-trivial... unless you are clever.
There are three key factors in selecting a biometric mechanism. What are they? (A) Encryption strength, authorization method, and cost (B) Reliability, user acceptance, and cost (C) User acceptance, encryption strength, and cost (D) Reliability, encryption strength, and cost
(B) Reliability, user acceptance, and cost The key factors in selecting a biometric mechanism are usually reliability, user acceptance, and cost.
Some of your users are complaining that they cannot access web sites and email. They are able to SSH to your corporate SSH gateway at 10.10.10.13, and ping their local gateway 10.10.10.24. What port (TCP and UDP) is the users' host based firewall blocking that would cause this behavior? (A) The firewall is blocking port 35 (B) The firewall is blocking port 53 (C) The firewall is blocking port 23 (D) The firewall is blocking port 32
(B) The firewall is blocking port 53 The fact that the users are able to ping multiple IP addresses indicates that this is not a network connectivity problem. Before the clients can connect the computer must convert the domain name to an IP address. This is generally done via the DNS service. The DNS service typically runs on TCP and UDP port 53 (UDP for queries, TCP for zone transfers). Port 23 is used for Telnet. The other ports are not typically found on most networks.
A security administrator downloads a template from NIST and applies it to user workstations. Complaints about not being able to access some network services soon flood the helpdesk. Which of the following choices is the most likely cause of the incident? (A) The firewall doesn't recognize changes made by the template (B) The template needs to be customized for the network (C) NIST templates are designed for stand alone systems (D) Security configurations need to be built on the individual machines
(B) The template needs to be customized for the network Security templates may have to be customized to fit a specific network, as not everything can be taken into account, an administrator must know their own network but they don't have to start from scratch.
Which of the following is characteristic of a procedure? (A) Sets a starting point (B) Presents a recommendation (C) Addresses the how to do it (D) Addresses the what to do
(C) Addresses the how to do it Procedures address the HOW to do it; are referenced when having trouble following the policy; are detailed and step by step; and are tactical. Policies address the WHAT to do; are read cover to cover; are concise and focused; and are strategic - high level. Guidelines present a recommendation as they are neither binding nor enforceable. Baselines set a starting point for comparison. Procedures are derived from policies; if you can characterize the procedures you follow (and you should be able to do that easily), then you can derive the parent policy. This is true even if it has not yet been written and signed. By walking through the who, what, when, where, and why, the parent policy is derived from an understanding of the procedure.
Which of the following is a characteristic of public key crypto algorithms? (A) No key encryption (B) 1-key encryption (C) Asymmetric key (D) Symmetric key
(C) Asymmetric key Public key crypto algorithms are asymmetric and have a dual or 2- key encryption scheme.
Idaho Taco Company has decided they want to deploy a honeypot to detect potential attack traffic against their public facing web server. Which network segment would be best suited for the placement of the honeypot? (A) Research & Development (B) File Storage (C) DMZ (D) Userland
(C) DMZ When using honeypots to detect potential attack traffic, it is best to patch the honeypots to similar levels as the target system and to place it on the same network segment.
Which of the following should be ensured before initiating a vulnerability scan? (A) Ensure that all denial of service filters are enabled (B) Ensure that the entire network is configured to be assessed at the same time (C) Ensure that IT staff and system owners have plenty of warning (D) Ensure that only commercial vulnerability scanners are utilized
(C) Ensure that IT staff and system owners have plenty of warning You should also be sure to give people plenty of warning before starting your scan. Things can go very wrong when you are scanning. Scans often crash systems, and people will be a lot more forgiving if you warn them ahead of time and make sure it is easy for them to find you.
Which of the following is a steganographic technique that places information into unused areas of a carrier file? (A) Generation (B) Permutation (C) Injection (D) Substitution
(C) Injection Injection is a steganography technique that places information into "holes," or unused areas of the file. Substitution is a popular steganography technique used to hide data in a host file. The concept is that elements are replaced on a bit-by-bit basis with information that is being hidden in the host document. Substitution also covers some cryptographic techniques. Arbitrary substitution requires a mapping for every character in the alphabet. An alternate substitution method that does not require mapping is rotation. Permutation, also called transposition, shuffles the order in which characters (or bytes) appear. Generation is another steganography technique that involves the actual generation of a new file from the data to be hidden. This is the only form of stego where a carrier isn't needed beforehand. A carrier file is needed, but it is generated on the fly by the stego program. The carrier file is actually created from the source information to be concealed. This can be used to generate such output as readable text or fractals. With each unique input file, a completely new and unique output file is generated..
What type of network design is needed to understand how network traffic is flowing in and out of an organization? (A) Virtual (B) Netflow (C) Logical (D) Conceptual
(C) Logical A logical design gives a more detailed view of the conceptual network design which will include major components such as business usage labels and specific application names. The logical architecture design can give you a clear understanding of how and where data is communicating in and out of your network. Conceptual design an abstract view of the network that gives an understandable picture of the network. Virtual network designs are network designed that only outlines the interconnection of virtual machines within and organization or data center.
What technique do Network Intrusion Prevention Systems use to identify host operating systems, network architecture, and vulnerabilities present on the network? (A) Protocol Scrubbing (B) Application Behavior Monitoring (C) Passive Analysis (D) Anomaly Analysis
(C) Passive Analysis In order to help the NIPS identify false-positive traffic, vendors make use of passive analysis techniques to identify host operating systems, network architecture and what vulnerabilities are present on the network. Once this information is gathered, the NIPS can use it to classify attacks against internal systems based on their operating system and vulnerabilities.
In keeping with the Principle of Least Privilege, which of the following NTFS group permissions should be assigned for Authenticated Users? (A) Encrypt & save (B) Create (C) Read & execute (D) Write
(C) Read & execute Principle of Least Privilege is this: Grant users the fewest permissions and privileges possible that still allow them to get their legitimate work done, but grant no more than that. If you're not sure where to start, a reasonable default set of permissions would be Full Control for System, Administrators and CREATOR OWNER, and just Read & Execute for Authenticated Users. In a more lax environment, you might grant Modify to Authenticated Users, which would also allow editing and deleting files.
A company allows RDP to be used for remote management of specific servers on the network. An attacker uses a Helpdesk employee's stolen credentials to remotely access a file server that is not on the list of approved RDP servers. Which security control would have prevented this attack vector? (A) Centralized logging (B) Anti-malware signatures (C) System hardening (D) Patch management
(C) System hardening Disable any and all services that are not essential to a system's function. Many operating systems come with unnecessary services installed and enabled out of the box, which can place a system at immediate risk once connected to a network. By carefully selecting options during installation and routinely auditing systems for unnecessary services or applications, risk can be significantly reduced
A user with local admin rights on a computer that is a member of a domain sets the group policy on their machine to allow a service not allowed in the domain group policy. After the user returns 2 hours later the service is disabled. Why is the service disabled? (A) A domain administrator noticed the discrepancy and restored the setting (B) Local GPO changes cannot enable services that are not enabled in the domain group policy (C) The domain GPO overwrote the local GPO when the system checked for updates (D) Local GPO changes only lasts for 1 hour
(C) The domain GPO overwrote the local GPO when the system checked for updates The computer will check for a group policy update every 90min by default for the domain and overwrite the local versions.
Which of the following is a trait of persistent cookies? (A) Additional authentication could be required to establish a session (B) They are stored in memory (C) They can create privacy concerns (D) They are the preferred mechanism to track web session state
(C) They can create privacy concerns Persistent cookies can create privacy concerns. Persistent cookies are stored on the disk. Because of this they create security concerns when used to track session state and additional authentication is required to establish a session.
Which of these log-monitoring detections is the highest priority security event for the log analyst performing daily log review? (A) Connections denied by the firewall (B) Web browsing to non-work-related websites (C) Unauthorized configuration changes (D) Collection of baseline data from a new logging source
(C) Unauthorized configuration changes Unauthorized configuration changes are indicators of compromise, and so should be investigated promptly. The remaining answers are tasks that typically are dealt with monthly or quarterly if at all.
What is a recommended action to take to make a wireless network more secure? (A) Implement per-packet authentication per the wired equivalency protocol spec (B) Implement MAC based access control on the Access Points (C) Use network authentication software like PEAP or TTLS (D) Use equipment which generates a strong signal to reduce interference (E) Configure the Access Points to hide or cloak the SSID
(C) Use network authentication software like PEAP or TTLS To prevent an attacker from spoofing the identity of an access point or legitimate node, an administrator can implement software like PEAP or TTLS which requires mutual authentication. If a wireless network is configured to hide or cloak its SSID, all an attacker has to do is sniff packets and wait until a client authenticates. Then he can grab the SSID. MAC based access control doesn't work effectively as a security mechanism because the attacker can sniff packets and determine "allowable" MAC addresses and then use one himself. To reduce the likelihood of eavesdropping, the recommendation is to limit signal strength through range-limiting antennas, placing access points as far from the exterior of the building as possible, etc. The wired equivalency protocol (802.11) spec does not address per-packet authentication.
A software engineer is expected to present on some lessons learned from a secure coding seminar they attended. Which best-practice would be included in the software engineer's presentation? (A) Ensure all alternative access methods are well hidden so that an adversary cannot take advantage of them (B) Display detailed error messages to facilitate speedy bug fixes (C) Validate all user input so that systems do not end up in an unintended state (D) Develop encryption algorithms using a reliable coding language so that the encryption will be robust
(C) Validate all user input so that systems do not end up in an unintended state User input always needs to be validated in order to protect against various input attacks. Clear error messages should not be displayed to the end user because that information would be valuable to a potential adversary. Detailed error messages should be logged, and vague error messages should be displayed to the end user. Homegrown encryption should be avoided because it is fragile and easy to break. Secrets should not be built into your code, no matter how well hidden. Code should be reviewed by a peer that understands the common mistakes that lead to vulnerabilities.
When two guest machines on the same physical host communicate, what is needed to make sure all traffic is properly analyzed? (A) Physical firewall (B) VLAN (C) Virtual firewall (D) NIDS
(C) Virtual firewall As a result of virtualization, standard network-based security controls are blind to this traffic and cannot perform monitoring or in-line blocking. In-line virtual appliances help to solve this problem; another approach to this issue is hardware-assisted virtualization, which requires integration with hardware hypervisors and virtualization management frameworks
What is the name of the registry key that is used to manage remote registry share permissions for the whole registry? (A) rrsreg (B) regkey (C) winreg (D) regmng
(C) winreg Whatever permissions you set on the "winreg" key regulate not only access to that key itself, but also the share permissions for the registry as a whole.
How many concurrent TCP streams can a firewall handle, using port address translation and a single, public, IP address? (A) 255 (B) 262140 (C) 10000 (D) 65535
(D) 65535 The port field was two bytes long or 16 bits - 2^16 is 65,536; because 0 is not typically a legal port value, this leaves us with 65,535 possible source or destination ports. This means that a firewall can track up to 65,535 concurrent UDP streams and 65,535 TCP connections from a single NAT address.
Which is a HIPS feature that locks an application into a sandbox, preventing communication with other applications? (A) Host Intrusion Process Sandboxing (B) Application Process Whitelisting (C) Application Process Validation (D) Advanced Application Shielding
(D) Advanced Application Shielding Advanced Application Shielding has recently been introduced in many vendor products over the last year. Often exploits rely on a systems applications to launch its attack(s). Advanced Application Shielding essentially locks an application into a sandbox where it is unable to communicate with other applications. Preventing an application from communicating with other applications in this case can mitigate a large threat. Neither Application Process Whitelisting, Host Intrusion Process Sandboxing, or Application Process Validation are recognized established features or methods of a Host Intrusion Prevention System.
Which of the following active defense tools opens up ports on a system to mislead, monitor, track, and block connections? (A) Decloak (B) NOVA (C) Honey Badger (D) BearTrap
(D) BearTrap BearTrap opens up ports on a system to mislead, monitor, track, and block connections. Decloak tries to discover an attackers "true" IP address. Honey Badger determines the physical location of a system. NOVA has the ability to launch several virtual machines.
Which class of IDS events occur when the IDS fails to alert on malicious data? (A) False Positive (B) True Positive (C) True Negative (D) False Negative
(D) False Negative False Negative events occur when the IDS identifies data as benign when in fact it is malicious.
Which of the following services/protocols does NOT integrate with Kerberos authentication under Windows 2000/2003? (A) Hypertext Transfer Protocol (HTTP) (B) Remote Procedure Calls (RPC) (C) Common Internet File System (CIFS) (D) File Transfer Protocol (FTP)
(D) File Transfer Protocol (FTP) The Kerberos authentication protocol can be used to authenticate many of the services that Microsoft Windows 2000/2003 utilizes regularly, including HTTP, Server Message Block (SMB)/CIFS, RPC and more. However, it cannot be used to authenticate telnet or FTP sessions.
A network uses 10.1.1.0/24 addressing for client systems and 10.5.5.0/24 for internal servers. Which of the following would prevent a host on the client network from sending packets with a spoofed source address of 10.5.5.101 to a host on the server network? (A) HIDS (B) Anti-virus (C) DHCP (D) Firewall
(D) Firewall Firewalls know which IP addresses should appear only inside a network segment and reject external traffic bearing those addresses. Spoofing will fail because the firewall will reject spoofed packets, which originated from outside the network yet appeared to use an internal IP address
When malware adds files or backdoors to a system, it violates which of the core CIA principles? (A) Availability (B) Identity (C) Authentication (D) Integrity
(D) Integrity By adding files, and possibly backdoor programs, to a system, worms and other malicious code create a problem of integrity. The system is no longer able to be altogether trusted. These do not inherently affect the availability of the system. Identity and Authentication are not part of CIA.
Which of the following best describes Defense-in-Depth? (A) Separation of duties (B) Risk management (C) Hardened perimeter security (D) Layered controls
(D) Layered controls Defense-in-depth is best characterized by layered defenses. The idea is that any layer of defense may eventually fail, but a Layered Defense offers better protection. Risk management, separation of duties, and hardened perimeters are part of a layered defense but do not describe the full concept of DiD.
What is a disadvantage of virtualizing a DMZ infrastructure? (A) Forensics analysis of a web server is more difficult (B) Still requires physical switches and firewalls (C) Guest hosts on the DMZ need to be running the same OS (D) Multiple systems running on the same physical hardware
(D) Multiple systems running on the same physical hardware If multiple virtual guests are running on the same hardware platform, and that system fails, all of the guest hosts will fail. Forensics analysis is easier in a virtual environment because a systems administrator could keep multiple instances of a server running at once, and if the instance bound to the network interface fails, he can unbind it and bind another instance to the network interface. In this case, he would have the compromised instance available for forensics analysis and it would not accessible to the network. Guest machines running different OSes can run in the same virtual environment. In a fully collapsed DMZ environment, switches and firewalls may be virtualized.
A company has network segments consisting of 200 machines each, with a firewall separating each segment. They use standard configuration for the workstations, firewalls, and switches in each segment that is appropriate for the security needs of that segment. This is an example of what type of defense strategy? (A) Vector-Oriented (B) Uniform Protection (C) Information-Centric (D) Protected Enclaves
(D) Protected Enclaves Protected enclaves involve segmenting your network. This can be done by implementing many VPNs across a single network, VLAN segmentation of switches, or firewalls to separate out the network. This is a simple, yet effective, technique. Reducing the exposure or visibility of a system can greatly reduce the impact malicious code can have. For example, if you have 5,000 systems on a network and a virus infection breaks out, it could spread to all systems. However if you create separate segments with 100 systems per segment, the virus would now impact only a small percent of your systems and cleanup and damage would be minimal.
From a security perspective, what should ALWAYS be used in conjunction with HTTP Basic Authentication? (A) Hypertext Markup Language (HTML) (B) Open Shortest Path First (OSPF) (C) Internet Control Message Protocol (ICMP) (D) Secure Sockets Layer (SSL)
(D) Secure Sockets Layer (SSL) Basic authentication sends passwords unencrypted. SSL should be used whenever basic authentication is required.
What information would an attacker need to carry out a TCP RST attack? (A) Routing table for the router (B) Router admin account and password (C) Target host MAC address (D) Source and target port numbers
(D) Source and target port numbers To carry out a TCP RST attack, an attacker would need to sniff packets exchanged between two hosts and determine the source and destination IP addresses, source and destination ports, and the changing sequence number. Then he could craft a packet with the Reset flag set by spoofing the original source port, IP address, and sequence number to make the target system think the original source wanted to end the conversation. An attacker with administrative access to a router would not be able to craft and inject packets into an ongoing TCP conversation. The TCP protocol does not include the MAC address. A routing table is used by a router to determine where to send packets based on IP addresses.
An analyst noticed that an internal database server exceeded its baseline outbound traffic. She then found the events below in syslog. What tool would accelerate this type of investigation? • External port scans on three external systems • Several login failures on the three external systems • Several login failures on a different internal server • Privileged account login on the database server (A) MySQL (B) Kiwi (C) grep (D) Splunk
(D) Splunk The events were from diverse systems and required investigation of many different log sources. By correlating the information across web servers, firewalls, and other security devices, tools such as Splunk can help identify those anomalies quickly. Kiwi (another syslog server) and MySQL centralize and store various logs, but won't correlate these events. Grep is useful for searching, but doesn't provide correlation.
Which is a property of an APT? (A) Automation (B) Opportunistic (C) Consistency (D) Stealth
(D) Stealth One of the properties of an APT is Stealthy. Three properties of a traditional threat are automated, consistent, and opportunistic.
Which type of steganography imposes limits on the amount of data that can be hidden? (A) Differential (B) Injection (C) File Generation (D) Substitution
(D) Substitution Substitution is the most popular stego method used to hide data in a host file. The concept is that elements are replaced on a bit-by-bit basis with information that is being hidden in the host document. Because the information is substituted in place of existing information, the file size of the carrier remains the same. However, since data is overwritten there are limits to how much data can be hidden. Both injection and file generation will increase carrier file size to accommodate the data to be hidden. Differential is a cryptanalysis technique.
What assurance do users have from a server using SSL? (A) The domain can be trusted for active content (B) The cookies will not store private information (C) The site has not been hacked (D) The certificate matches the domain
(D) The certificate matches the domain Server identity verification: Basically the name on the web server SSL certificate needs to exactly match the domain name in the browser's address bar. This confirms to the users that they are talking to the server to which they think they are talking.
Which of the following is necessary to detect unusual events through log correlation for the devices in an organization? (A) Visualization software for the combined system log files for the organization (B) Triggering for incident response team activation when anomalies are detected (C) Methodology for rotating and hashing central log files to prevent tampering (D) Understanding the normal network traffic and host activity for the organization
(D) Understanding the normal network traffic and host activity for the organization You first want to establish a baseline (what does the system look like under normal load?). This gives you something to compare to as utilization grows or when problems or incidents occur.
An organization is using RDP services to provide help desk support to their employees. They are using TLS encryption for the connections. What other action will improve the security of this process? (A) Use Group Policy to ensure that port 3389/tcp is blocked (B) Set the Terminal Services Authentication setting to "Negotiate" (C) Set the client to only connect through RDP Web Access (D) Use two-factor authentication for account sign-on
(D) Use two-factor authentication for account sign-on If possible, use Windows Server 2008 or later on the server to benefit from Network Level Authentication (NLA) and RDP single sign-on. The single sign-on works with either password or smart card authentication, so prefer smart cards too.
How is a Windows 2008 or 2012 server affected when the administrator disables the NetBIOS service? (A) The server's File and Print Sharing services will run over TCP port 139 (B) The server will be immune to null user session attacks (C) It will disable the Remote Procedure Call service on TCP port 135 (D) The server will not be able to access SMB shares on remote hosts (E) It will not have full backward compatibility with legacy systems like Windows NT
(E) It will not have full backward compatibility with legacy systems like Windows NT Disabling the NetBIOS service on a Windows server causes the server to not have full backward compatibility with old systems like Windows NT or legacy applications. The server will, however, be able to access SMB shares on other hosts as long as the NetBIOS Helper service is still running. Null Session user attacks do not require NetBIOS. The RPC service will not be affected if the NetBIOS service is disabled. When NetBIOS is running, file and print sharing services run over TCP port 139, otherwise they run on TCP port 445.

B. You did not enable auditing on the files
You are doing some analysis of malware on a Unix computer in a closed test network. The IP address of the computer is 192.168.1.120. From a packet capture, you see the malware is attempting to do a DNS query for a server called iamabadserver.com so that it can connect to it. There is no DNS server on the test network to do name resolution. You have another computer, whose IP is 192.168.1.115, available on the test network that you would like for the malware connect to it instead. How do you get the malware to connect to that computer on the test network? A.
