QUESTION 455
Which of the following security architecture elements also has sniffer functionality? (Select TWO).
A. HSM
B. IPS
C. SSL accelerator
D. WAP
E. IDS
Answer: BE
Explanation:
Sniffer functionality means the ability to capture and analyze the content of data packets as they are transmitted across the network.
IDS and IPS systems perform their functions by capturing and analyzing the content of data packets.
An intrusion detection system (IDS) is a device or software application that monitors network or system activities for malicious activities or policy violations and produces reports to a management station. IDS come in a variety of “flavors” and approach the goal of detecting suspicious traffic in different ways. There are network based (NIDS) and host based (HIDS) intrusion detection systems. Some systems may attempt to stop an intrusion attempt but this is neither required nor expected of a monitoring system. Intrusion detection and prevention systems (IDPS) are primarily focused on identifying possible incidents, logging information about them, and reporting attempts. In addition, organizations use IDPSes for other purposes, such as identifying problems with security policies, documenting existing threats and deterring individuals from violating security policies. IDPSes have become a necessary addition to the security infrastructure of nearly every organization.
IDPSes typically record information related to observed events, notify security administrators of important observed events and produce reports. Many IDPSes can also respond to a detected threat by attempting to prevent it from succeeding. They use several response techniques, which involve the IDPS stopping the attack itself, changing the security environment (e.g. reconfiguring a firewall) or changing the attack’s content.
QUESTION 456
Which of the following would a security administrator implement in order to discover comprehensive security threats on a network?
A. Design reviews
B. Baseline reporting
C. Vulnerability scan
D. Code review
Answer: C
Explanation:
A vulnerability scan is the process of scanning the network and/or I.T. infrastructure for threats and vulnerabilities. Vulnerabilities include computer systems that do not have the latest security patches installed.
The threats and vulnerabilities are then evaluated in a risk assessment and the necessary actions taken to resolve and vulnerabilities.
A vulnerability scan is the automated process of proactively identifying security vulnerabilities of computing systems in a network in order to determine if and where a system can be exploited and/or threatened. While public servers are important for communication and data transfer over the Internet, they open the door to potential security breaches by threat agents, such as malicious hackers.
Vulnerability scanning employs software that seeks out security flaws based on a database of known flaws, testing systems for the occurrence of these flaws and generating a report of the findings that an individual or an enterprise can use to tighten the network’s security. Vulnerability scanning typically refers to the scanning of systems that are connected to the Internet but can also refer to system audits on internal networks that are not connected to the Internet in order to assess the threat of rogue software or malicious employees in an enterprise.

QUESTION 459
Which of the following should an administrator implement to research current attack methodologies?
A. Design reviews
B. Honeypot
C. Vulnerability scanner
D. Code reviews
Answer: B
Explanation:
A honeypot is a system whose purpose it is to be attacked. An administrator can watch and study the attack to research current attack methodologies.
According to the Wepopedia.com, a Honeypot luring a hacker into a system has several main purposes:
The administrator can watch the hacker exploit the vulnerabilities of the system, thereby learning where the system has weaknesses that need to be redesigned. The hacker can be caught and stopped while trying to obtain root access to the system. By studying the activities of hackers, designers can better create more secure systems that are potentially invulnerable to future hackers.
There are two main types of honeypots:
Production – A production honeypot is one used within an organization’s environment to help mitigate risk.
Research ?A research honeypot add value to research in computer security by providing a platform to study the threat.

QUESTION 464
Several users report to the administrator that they are having issues downloading files from the file server. Which of the following assessment tools can be used to determine if there is an issue with the file server?
A. MAC filter list
B. Recovery agent
C. Baselines
D. Access list
Answer: C
Explanation:
The standard configuration on a server is known as the baseline. In this question, we can see if anything has changed on the file server by comparing its current configuration with the baseline. The IT baseline protection approach is a methodology to identify and implement computer security measures in an organization. The aim is the achievement of an adequate and appropriate level of security for IT systems. This is known as a baseline.
A baseline report compares the current status of network systems in terms of security updates, performance or other metrics to a predefined set of standards (the baseline).
QUESTION 465

Explanation:
A performance baseline provides the input needed to design, implement, and support a secure network. The performance baseline would define the actions that should be performed on a server that is running low on memory.
QUESTION 466
Ann, the software security engineer, works for a major software vendor. Which of the following practices should be implemented to help prevent race conditions, buffer overflows, and other similar vulnerabilities prior to each production release?
A. Product baseline report
B. Input validation
C. Patch regression testing
D. Code review
Answer: D
Explanation:
The problems listed in this question can be caused by problems with the application code.
Reviewing the code will help to prevent the problems.
The purpose of code review is to look at all custom written code for holes that may exist. The review needs also to examine changes that the code–most likely in the form of a finished application–may make: configuration files, libraries, and the like. During this examination, look for threats such as opportunities for injection to occur (SQL, LDAP, code, and so on), cross-site request forgery, and authentication. Code review is often conducted as a part of gray box testing. Looking at source code can often be one of the easiest ways to find weaknesses within the application. Simply reading the code is known as manual assessment, whereas using tools to scan the code is known as automated assessment.
QUESTION 467
Which of the following assessment techniques would a security administrator implement to ensure that systems and software are developed properly?
A. Baseline reporting
B. Input validation
C. Determine attack surface
D. Design reviews
Answer: D
Explanation:
When implementing systems and software, an important step is the design of the systems and software. The systems and software should be designed to ensure that the system works as intended and is secure.
The design review assessment examines the ports and protocols used, the rules, segmentation, and access control in the system or application. A design review is basically a check to ensure that the design of the system meets the security requirements.

When implementing a VPN, an important step is the design of the VPN. The VPN should be designed to ensure that the security of the network and local systems is not compromised. The design review assessment examines the ports and protocols used, the rules, segmentation, and access control in the systems or applications. A design review is basically a check to ensure that the design of the system meets the security requirements.
QUESTION 469
Which of the following assessments would Pete, the security administrator, use to actively test that an application’s security controls are in place?
A. Code review
B. Penetration test
C. Protocol analyzer
D. Vulnerability scan
Answer: B
Explanation:
Penetration testing (also called pen testing) is the practice of testing a computer system, network or Web application to find vulnerabilities that an attacker could exploit. Pen tests can be automated with software applications or they can be performed manually. Either way, the process includes gathering information about the target before the test (reconnaissance), identifying possible entry points, attempting to break in (either virtually or for real) and reporting back the findings.
The main objective of penetration testing is to determine security weaknesses. A pen test can also be used to test an organization’s security policy compliance, its employees’ security awareness and the organization’s ability to identify and respond to security incidents. Penetration tests are sometimes called white hat attacks because in a pen test, the good guys are attempting to break in.
Pen test strategies include:
Targeted testing
Targeted testing is performed by the organization’s IT team and the penetration testing team working together. It’s sometimes referred to as a “lights-turned-on” approach because everyone can see the test being carried out.
External testing
This type of pen test targets a company’s externally visible servers or devices including domain name servers (DNS), e-mail servers, Web servers or firewalls. The objective is to find out if an outside attacker can get in and how far they can get in once they’ve gained access.
Internal testing
This test mimics an inside attack behind the firewall by an authorized user with standard access privileges. This kind of test is useful for estimating how much damage a disgruntled employee could cause.
Blind testing
A blind test strategy simulates the actions and procedures of a real attacker by severely limiting the information given to the person or team that’s performing the test beforehand. Typically, they may only be given the name of the company. Because this type of test can require a considerable amount of time for reconnaissance, it can be expensive.
Double blind testing
Double blind testing takes the blind test and carries it a step further. In this type of pen test, only one or two people within the organization might be aware a test is being conducted. Double-blind tests can be useful for testing an organization’s security monitoring and incident identification as well as its response procedures.
QUESTION 470
Which of the following is the MOST intrusive type of testing against a production system?
A. White box testing
B. War dialing
C. Vulnerability testing
D. Penetration testing
Answer: D

Mike, a security professional, is tasked with actively verifying the strength of the security controls on a company’s live modem pool. Which of the following activities is MOST appropriate?
A. War dialing
B. War chalking
C. War driving
D. Bluesnarfing
Answer: A
Explanation:
War dialing is a technique of using a modem to automatically scan a list of telephone numbers, usually dialing every number in a local area code to search for computers, Bulletin board systems and fax machines. Hackers use the resulting lists for various purposes: hobbyists for exploration, and crackers – malicious hackers who specialize in computer security – for guessing user accounts (by capturing voicemail greetings), or locating modems that might provide an entry-point into computer or other electronic systems. It may also be used by security personnel, for example, to detect unauthorized devices, such as modems or faxes, on a company’s telephone network.
