The elements of security are as follows: 1.Confidentiality: It is the concealment of information or resources. 2.Authenticity: It is the identification and assurance of the origin of information. 3.Integrity: It refers to the trustworthiness of data or resources in terms of preventing improper and unauthorized changes. 4.Availability: It refers to the ability to use the information or resources as desired.

A cold site provides an office space, and in some cases basic equipment. However, you will need to restore your data to that equipment in order to use it. This is a much less expensive solution than the hot site. Answer D is incorrect. A hot site has equipment installed, configured and ready to use. This may make disaster recovery much faster, but will also be more expensive. And a school district can afford to be down for several hours before resuming IT operations, so the less expensive option is more appropriate. Answer C is incorrect. A warm site is between a hot and cold site. It has some equipment ready and connectivity ready. However, it is still significantly more expensive than a cold site, and not necessary for this scenario. Answer B is incorrect. Off site is not any type of backup site terminology.

Contingency plan is prepared and documented for emergency response, backup operations, and recovery maintained by an activity as the element of its security program that will ensure the availability of critical resources and facilitates the continuity of operations in an emergency situation. 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 D is incorrect. A disaster recovery plan should contain data, hardware, and software that can be critical for a business. It should also include the plan for sudden loss such as hard disc crash. The business should use backup and data recovery utilities to limit the loss of data. 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. Answer B is incorrect. 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.

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.
