The National Institute of Standards and Technology (NIST), known between 1901 and 1988 as the National Bureau of Standards (NBS), is a measurement standards laboratory which is a non-regulatory agency of the United States Department of Commerce. The institute's official mission is to promote U.S. innovation and industrial competitiveness by advancing measurement science, standards, and technology in ways that enhance economic security and improve quality of life. Answer: D is incorrect. The Committee on National Security Systems (CNSS) is a United States intergovernmental organization that sets policy for the security of the US security systems. The CNSS holds discussions of policy issues, sets national policy, directions, operational procedures, and guidance for the information systems operated by the U.S. Government, its contractors, or agents that contain classified information, involve intelligence activities, involve cryptographic activities related to national security, etc. Answer: A is incorrect.

The National Security Agency/Central Security Service (NSA/CSS) is a crypto-logic intelligence agency of the United States government. It is administered as part of the United States Department of Defense. NSA is responsible for the collection and analysis of foreign communications and foreign signals intelligence, which involves cryptanalysis. NSA is also responsible for protecting U.S. government communications and information systems from similar agencies elsewhere, which involves cryptography. NSA is a key component of the U.S. Intelligence Community, which is headed by the Director of National Intelligence. The Central Security Service is a co-located agency created to coordinate intelligence activities and co-operation between NSA and U.S. military cryptanalysis agencies. NSA's work is limited to communications intelligence. It does not perform field or human intelligence activities. Answer: C is incorrect. The United States Congress is the bicameral legislature of the federal government of the United States of America. It consists of the Senate and the House of Representatives. The Congress meets in the United States Capitol in Washington, D.C. Both senators and representatives are chosen through direct election. Each of the 435 members of the House of Representatives represents a district and serves a two-year term. House seats are apportioned among the states by population. The 100 Senators serve staggered six-year terms. Each state has two senators, regardless of population. Every two years, approximately one-third of the Senate is elected at a time. The United States Congress main function is to make laws. The Office of the Law Revision Counsel organizes and publishes the United States Code (USC). It is a consolidation and codification by subject matter of the general and permanent laws of the United States.

Continuous Monitoring is the fourth phase of the security certification and accreditation process. The Continuous Monitoring process consists of the following three main activities: Configuration management and control Security control monitoring and impact analyses of changes to the information system Status reporting and documentation The objective of these tasks is to observe and evaluate the information system security controls during the system life cycle. These tasks determine whether the changes that have occurred will negatively impact the system security. Answer: A and C are incorrect. Security accreditation decision and security accreditation documentation are the two tasks of the security accreditation phase.

Passive OS fingerprinting can identify attacks originating from a botnet. Network Administrators can configure the firewall to take action on a botnet attack by using information obtained from passive OS fingerprinting. Passive OS fingerprinting (POSFP) allows the sensor to determine the operating system used by the hosts. The sensor examines the traffic flow between two hosts and then stores the operating system of those two hosts along with their IP addresses. In order to determine the type of operating system, the sensor analyzes TCP SYN and SYN ACK packets that are traveled on the network. The sensor computes the attack relevance rating to determine the relevancy of victim attack using the target host OS. After it, the sensor modifies the alert's risk rating or filters the alert for the attack. Passive OS fingerprinting is also used to improve the alert output by reporting some information, such as victim OS, relevancy to the victim in the alert, and source of the OS identification. Answer: D is incorrect. A BPF-based filter is used to limit the number of packets seen by tcpdump; this renders the output more usable on networks with a high volume of traffic. Answer: B is incorrect. Recipient filtering is used to block messages on the basis of whom they are sent to. Answer: C is incorrect. IFilters are used to extract contents from files that are crawled. IFilters also remove application-specific formatting before the content of a document is indexed by the search engine.

BCP is a strategy to minimize the consequence of the instability and to allow for the continuation of business processes. The goal of BCP is to minimize the effects of a disruptive event on a company, and is formed to avoid interruptions to normal business activity. Business Continuity Planning (BCP) is the creation and validation of a practiced logistical plan for how an organization will recover and restore partially or completely interrupted critical (urgent) functions within a predetermined time after a disaster or extended disruption. The logistical plan is called a business continuity plan. Answer: B is incorrect. A contingency plan is a plan devised for a specific situation when things could go wrong. Contingency plans are often devised by governments or businesses who want to be prepared for anything that could happen. Contingency plans include specific strategies and actions to deal with specific variances to assumptions resulting in a particular problem, emergency, or state of affairs. They also include a monitoring process and "triggers" for initiating planned actions. They are required to help governments, businesses, or individuals to recover from serious incidents in the minimum time with minimum cost and disruption. Answer: C is incorrect. Disaster recovery planning is a subset of a larger process known as business continuity planning and should include planning for resumption of applications, data, hardware, communications (such as networking), and other IT infrastructure. A business continuity plan (BCP) includes planning for non-IT related aspects such as key personnel, facilities, crisis communication, and reputation protection, and should refer to the disaster recovery plan (DRP) for IT-related infrastructure recovery/continuity. Answer: A is incorrect. The Continuity Of Operation Plan (COOP) refers to the preparations and institutions maintained by the United States government, providing survival of federal government operations in the case of catastrophic events. It provides procedures and capabilities to sustain an organization's essential. COOP is the procedure documented to ensure persistent critical operations throughout any period where normal operations are unattainable.
