QUESTION 543
A computer is suspected of being compromised by malware. The security analyst examines the computer and finds that a service called Telnet is running and connecting to an external website over port 443. This Telnet service was found by comparing the system’s services to the list of standard services on the company’s system image. This review process depends on:
A. MAC filtering.
B. System hardening.
C. Rogue machine detection.
D. Baselining.
Answer: D
Explanation:
Application baseline defines the level or standard of security that will be implemented and maintained for the application. It may include requirements of hardware components, operating system versions, patch levels, installed applications and their configurations, and available ports and services. Systems can be compared to the baseline to ensure that the required level of security is being maintained.

Identifying a list of all approved software on a system is a step in which of the following practices?
A. Passively testing security controls
B. Application hardening
C. Host software baselining
D. Client-side targeting
Answer: C
Explanation:
Application baseline defines the level or standard of security that will be implemented and maintained for the application. It may include requirements of hardware components, operating system versions, patch levels, installed applications and their configurations, and available ports and services.

QUESTION 545
A new application needs to be deployed on a virtual server. The virtual server hosts a SQL server that is used by several employees.
Which of the following is the BEST approach for implementation of the new application on the virtual server?
A. Take a snapshot of the virtual server after installing the new application and store the snapshot in a secure location.
B. Generate a baseline report detailing all installed applications on the virtualized server after installing the new application.
C. Take a snapshot of the virtual server before installing the new application and store the snapshot in a secure location.
D. Create an exact copy of the virtual server and store the copy on an external hard drive after installing the new application.
Answer: C
Explanation:
Snapshots are backups of virtual machines that can be used to quickly recover from poor updates, and errors arising from newly installed applications. However, the snapshot should be taken before the application or update is installed.
QUESTION 546
The information security technician wants to ensure security controls are deployed and functioning as intended to be able to maintain an appropriate security posture. Which of the following security techniques is MOST appropriate to do this?
A. Log audits
B. System hardening
C. Use IPS/IDS
D. Continuous security monitoring
Answer: D
Explanation:
A security baseline is the security setting of a system that is known to be secure. This is the initial security setting of a system. Once the baseline has been applied, it must be maintained or improved. Maintaining the security baseline requires continuous monitoring.
QUESTION 547
Which of the following solutions provides the most flexibility when testing new security controls prior to implementation?
A. Trusted OS
B. Host software baselining
C. OS hardening
D. Virtualization
Answer: D
Explanation:
Virtualization is used to host one or more operating systems in the memory of a single host computer and allows multiple operating systems to run simultaneously on the same hardware. Virtualization offers the flexibility of quickly and easily making backups of entire virtual systems, and quickly recovering the virtual system when errors occur. Furthermore, malicious code compromises of virtual systems rarely affect the host system, which allows for safer testing and experimentation.
QUESTION 548
A company is about to release a very large patch to its customers.
An administrator is required to test patch installations several times prior to distributing them to customer PCs.
Which of the following should the administrator use to test the patching process quickly and often?

B. Create an image of a patched PC and replicate it to servers
C. Create a full disk image to restore after each installation
D. Create a virtualized sandbox and utilize snapshots
Answer: D
Explanation:
Sandboxing is the process of isolating a system before installing new applications or patches on it so as to restrict the software from being able to cause harm to production systems. Before the patch is installed, a snapshot of the system should be taken. Snapshots are backups that can be used to quickly recover from poor updates, and errors arising from newly installed applications.
