Security constraint  

Explanation: Security constraint is a type of declarative security, which specifies the protection of web content. It also specifies access privileges to a collection of resources by using the URL mapping. A deployment descriptor is used to define the security constraint. Security constraint includes the following elements: Web resource collection Authorization constraint User data constraint Answer: A is incorrect. Code Access Security (CAS), in the Microsoft .NET framework, is Microsoft's solution to prevent untrusted code from performing privileged actions. When the CLR (common language runtime) loads an assembly it will obtain evidence for the assembly and use this to identify the code group that the assembly belongs to. A code group contains a permission set (one or more permissions). Code that performs a privileged action will perform a code access demand, which will cause the CLR to walk up the call stack and examine the permission set granted to the assembly of each method in the call stack. The code groups and permission sets are determined by the administrator of the machine who defines the security policy. Answer: D is incorrect. Access Management is used to grant authorized users the right to use a service, while preventing access to non- authorized users. The Access Management process essentially executes policies defined in IT Security Management. It is sometimes also referred to as Rights Management or Identity Management. It is part of Service Operation and the owner of Access Management is the Access Manager. Access Management is added as a new process to ITIL V3. The sub-processes of Access Management are as follows: Maintain Catalogue of User Roles and Access Profiles Manage User Access Requests Answer: C is incorrect. Configuration Management (CM) is an Information Technology Infrastructure Library (ITIL) IT Service Management (ITSM) process. It tracks all of the individual Configuration Items (CI) in an IT system, which may be as simple as a single server, or as complex as the entire IT department. In large organizations a configuration manager may be appointed to oversee and manage the CM process. 

DARPA 

Explanation: The Defense Advanced Research Projects Agency (DARPA) is an agency of the United States Department of Defense responsible for the development of new technology for use by the military. DARPA has been responsible for funding the development of many technologies which have had a major effect on the world, including computer networking, as well as NLS, which was both the first hypertext system, and an important precursor to the contemporary ubiquitous graphical user interface. DARPA supplies technological options for the entire Department, and is designed to be the "technological engine" for transforming DoD. Answer: D is incorrect. The Defense Information Systems Agency is a United States Department of Defense combat support agency with the goal of providing real-time information technology (IT) and communications support to the President, Vice President, Secretary of Defense, the military Services, and the Combatant Commands. DISA, a Combat Support Agency, engineers and provides command and control capabilities and enterprise infrastructure to continuously operate and assure a global net-centric enterprise in direct support to joint warfighters, National level leaders, and other mission and coalition partners across the full spectrum of operations. Answer: B is incorrect. The Defense Technical Information Center (DTIC) is a repository of scientific and technical documents for the United States Department of Defense. DTIC serves the DoD community as the largest central resource for DoD and government-funded scientific, technical, engineering, and business related information available today. DTIC's documents are available to DoD personnel and defense contractors, with unclassified documents also available to the public. DTIC's aim is to serve a vital link in the transfer of information among DoD personnel, DoD contractors, and potential contractors and other U.S. Government agency personnel and their contractors. Answer: A is incorrect. The Defense-wide Information Assurance Program (DIAP) protects and supports DoD information, information systems, and information networks, which is important to the Department and the armed forces throughout the day-to-day operations, and in the time of crisis. The DIAP uses the OSD method to plan, observe, organize, and incorporate IA activities. The role of DIAP is to act as a facilitator for program execution by the combatant commanders, Military Services, and Defense Agencies. The DIAP staff combines functional and programmatic skills for a comprehensive Defense-wide approach to IA. The DIAP's main objective is to ensure that the DoD's vital information resources are secured and protected by incorporating IA activities to get a secure net-centric GIG operation enablement and information supremacy by applying a Defense-in-Depth methodology that integrates the capabilities of people, operations, and technology to establish a multi-layer, multidimensional protection. 

Pipes and filters 

Explanation: In the pipes and filters architecture style, a device receives input from connectors and generates transformed outputs. A pipeline has a series of processing elements in which the output of each element works as an input of the next element. A little amount of buffering is provided between the two successive elements.

Keystroke logging

Explanation: Keystroke logging is used by attackers to record everything a person types, including usernames, passwords, and account information. Keystroke logging is a method of logging and recording user keystrokes. It can be performed with software or hardware devices. Keystroke logging devices can record everything a person types using his keyboard, such as to measure employee's productivity on certain clerical tasks. These types of devices can also be used to get usernames, passwords, etc. Answer: D is incorrect. Wiretapping is used to eavesdrop on voice calls. Eavesdropping is the process of listening in on private conversations. It also includes attackers listening in on network traffic. Answer: C is incorrect. Spoofing is a technique that makes a transmission appear to have come from an authentic source by forging the IP address, email address, caller ID, etc. In IP spoofing, a hacker modifies packet headers by using someone else's IP address to hide his identity. However, spoofing cannot be used while surfing the Internet, chatting on-line, etc. because forging the source IP address causes the responses to be misdirected. Answer: A is incorrect. Packet sniffing is a process of monitoring data packets that travel across a network. The software used for packet sniffing is known as sniffers. There are many packet-sniffing programs that are available on the Internet. Some of these are unauthorized, which can be harmful for a network's security. 

National Institute of Standards and Technology (NIST) 

Explanation: 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.
