QUESTION: 198

Which of the following is an open source network intrusion detection system?

NETSH
Macof
Sourcefire
Snort

Answer(s): D

Explanation:

Snort is an open source network intrusion prevention and detection system that operates as a network sniffer. It logs activities of the network that is matched with the predefined signatures. Signatures can be designed for a wide range of traffic, including Internet Protocol (IP), Transmission Control Protocol (TCP), User Datagram Protocol (UDP), and Internet Control Message Protocol (ICMP). The three main modes in which Snort can be configured are as follows:
Sniffer mode: It reads the packets of the network and displays them in a continuous stream on the console. Packet logger mode: It logs the packets to the disk. Network intrusion detection mode: It is the most complex and configurable configuration, allowing Snort to analyze network traffic for matches against a user-defined rule set. Answer B is incorrect. Macof is a tool of the dsniff tool set and used to flood the local network with random MAC addresses. It causes some switches to fail open in repeating mode, and facilitates sniffing. Answer C is incorrect. Sourcefire is the company that owns and maintains Snort. Answer A is incorrect. NETSH is not a network intrusion detection system. NETSH is a command line tool to configure TCP/IP settings such as the IP address, Subnet Mask, Default Gateway, DNS, WINS addresses, etc.

QUESTION: 200

Adrian is the project manager of the NHP Project. In her project there are several work packages that deal with electrical wiring. Rather than to manage the risk internally she has decided to hire a vendor to complete all work packages that deal with the electrical wiring. By removing the risk internally to a licensed electrician Adrian feels more comfortable with project team being safe. What type of risk response has Adrian used in this example?

Acceptance
Avoidance
Mitigation
Transference

Answer(s): D

Explanation:

This is an example of transference. When the risk is transferred to a third party, usually for a fee, it creates a contractual-relationship for the third party to manage the risk on behalf of the performing organization. Risk response planning is a method of developing options to decrease the amount of threats and make the most of opportunities. The risk response should be aligned with the consequence of the risk and cost-effectiveness. This planning documents the processes for managing risk events. It addresses the owners and their responsibilities, risk identification, results from qualification and quantification processes, budgets and times for responses, and contingency plans. The various risk response planning techniques are as follows: Risk acceptance: It indicates that the project team has decided not to change the project management plan to deal with a risk, or is unable to identify any other suitable response strategy. Risk avoidance: It is a technique for a threat, which creates changes to the project management plan that are meant to either eliminate the risk or to protect the project objectives from this impact. Risk mitigation: It is a list of specific actions being taken to deal with specific risks associated with the threats and seeks to reduce the probability of occurrence or impact of risk below an acceptable threshold. Risk transference: It is used to shift the impact of a threat to a third party, together with the ownership of the response.

QUESTION: 201

You work as a CSO (Chief Security Officer) for Tech Perfect Inc. You have a disaster scenario and you want to discuss it with your team members for getting appropriate responses of the disaster. In which of the following disaster recovery tests can this task be performed?

Structured walk-through test
Full-interruption test
Parallel test
Simulation test

Answer(s): D

Explanation:

A simulation test is a method used to test the disaster recovery plans. It operates just like a structured walk-through test. In the simulation test, the members of a disaster recovery team present with a disaster scenario and then, discuss on appropriate responses. These suggested responses are measured and some of them are taken by the team. The range of the simulation test should be defined carefully for avoiding excessive disruption of normal business activities. Answer A is incorrect. The structured walk-through test is also known as the table-top exercise. In structured walk-through test, the team members walkthrough the plan to identify and correct weaknesses and how they will respond to the emergency scenarios by stepping in the course of the plan. It is the most effective and competent way to identify the areas of overlap in the plan before conducting more challenging training exercises. Answer B is incorrect. A full-interruption test includes the operations that shut down at the primary site and are shifted to the recovery site according to the disaster recovery plan. It operates just like a parallel test. The full-interruption test is very expensive and difficult to arrange. Sometimes, it causes a major disruption of operations if the test fails. Answer C is incorrect. A parallel test includes the next level in the testing procedure, and relocates the employees to an alternate recovery site and implements site activation procedures. These employees present with their disaster recovery responsibilities as they would for an actual disaster. The disaster recovery sites have full responsibilities to conduct the day-to-day organization's business.
