RISK ASSESSMENT on the Department of the Army IT Systems Essay Example for Free

RISK ASSESSMENT on the Department of the Army IT Systems Essay 1.Introduction 1.1 Purpose This risk assessment was to identify threats and vulnerabilities related to the Department of the Army (DoA) Information Technology (IT) systems. It will be utilized to identify vulnerabilities in the Computer Network Defense (CND) Capabilities and mitigation plans related to DoA’s IT systems. It was realized that this was a potential high-risk system as noted by the Department of Defense (DoD) Chief Information Officer (CIO). (DoD, 2012) 1.2 Scope This risk assessment applies to all DoA Non-secured Internet Protocol Router Network (NIPRNET) and Secured Internet Protocol Router Network (SIPRNET) for Regular Army and Reserve Components. This is a major system that is used by millions of Soldiers, contractors and DA civilians worldwide. The DoA’s IT system is comprised of Army Global Network Operations and Security Center (A-GNOSC) which is responsible for the Army’s day-to-day Tier 2 CND Service Provider. The research methods will present both quantitative and qualitative data which will identify hazards and vulnerabilities to include International-Transnational Terrorism and Domestic Terrorism and present an assessment of the potential risks from them. Information will be collected mainly from DoD’s and DA’s websites. SYSTEM CHARACTERIZATION The DoD uses DODI 8510.01, DoD Information Assurance Certification and Accreditation Process (DIACAP), as the process for implementing Certification and Accreditation (CA) within their information system. The Information Assurance (IA) Controls, or security measures that must be implemented on a system, as stated in the DODI 8500.2, Information Assurance (IA) Implementation. The control selection relies on the Mission Assurance Categories (MAC) and Confidentiality Levels (CL). Information Systems (IS) will be allotted a MAC level which shows the importance of the information which is used to determine the IA controls for integrity and availability regarding DODI 8500.2 and will be decided by the DoD or Army by the DIACAP  team (Information Assurance, 2009) MISSION ASSURANCE CATEGORY MAC IIs a high integrity, high availability for DoD ISs handling information that is determined to be vital to the operational readiness or mission effectiveness of deployed and contingency forces in terms of both content and timeliness. The consequence of loss of integrity or availability is unacceptable and could include the immediate and sustained loss of mission effectiveness. MAC IIIs a high integrity, medium availability for DoD ISs handling information that is important to the support of deployed and contingency forces. The consequence of loss of integrity is unacceptable. Loss of availability is difficult to deal with and can only be tolerated for a short time. MAC IIIIs a basic integrity, basic availability for DoD ISs handling information that is necessary for the conduct of day-to-day business, but does not materially affect support to deployed or contingency forces in the short- term. The consequences of loss of integrity or availability can be tolerated or overcome witho ut significant impacts on mission effectiveness or operational readiness. CONFIDENTIALITY LEVELAll ISs will be assigned a confidentiality level based on the classification or sensitivity of the information processed. The confidentiality level is used to establish acceptable access factors and to determine the DODI 8500.2 IA Controls applicable to the information system. DOD has defined the following three confidentiality levels: 1.ClassifiedInformation designated top secret, secret or confidential in accordance with Executive Order 12356. 2.SensitiveInformation the loss, or unauthorized access to or modification of could adversely affect the national interest or conduct of Federal programs, or Privacy Act information. Includes, but is not limited to For Official Use Only (FOUO), Privacy data, unclassified controlled nuclear information, and unclassified technical data. 3.PublicInformation has been reviewed and approved for public release.

(2012) THREAT IDENTIFICATION Data from the DoD shows a 20% rise in attacks against its information systems from 43,880 to 54,640 between 2007 to 2008. â€Å"Each of these penetrations involves a series of actions that do not differ substantially whether the intruder is acting on behalf of a terrorist group, a foreign government, a corporation, or is acting as individual. The severe intrusions into cyber systems involve penetrating system security, navigating and mapping the cyber system, targeting the nodes that control the system and contain the most critical data, and often, extracting the data.† (Wortzel, 2009) â€Å"In February 2011, the Deputy Secretary of Defense said that more than 100 foreign intelligence agencies have tried to breach DOD computer networks and that one was successful in breaching networks containing classified information.2 Also, the President of the United States has identified this threat as one of the most serious national security challenges facing the nation.† (Dâ€⠄¢Agostino, 2011, pp. 1) VULNERABILITY IDENTIFICATION THREAT CapabilitySecurity Test ResultsAudit CommentsSeverity SW BaselineNo SW baselineThe DA does not have a documented software inventory.

(DAIG IA, 2009) SUMMARY Risk Vulnerability/ThreatRisk LevelRecommended ControlsAction Priority Hardware baseline inventory is incomplete. This could lead to the introduction of unauthorized into the network and also makes it difficult to maintain an effective life cycle managementLowComplete current hardware baseline and continue to identify and document future assets.Low Configuration management is not complete and this could lead to changes being made to the environment that unknowingly introduce vulnerabilities. This should be assessed by an IA team before introduced to the network.LowFinalize the configuration management process and implement a plan to assess IA impact of change to the system.Low Open ports, protocols and services. Changes made to the open PPS will lead to exploits and/or data compromise.MediumEnsure that the change management process relating to PPS are developed and enforced.Medium REFERENCES Bendel, B.
