Cyber Security Research Paper Essay
1. Preface This security profile of the Department of Veterans Affairs (VA) is based on two documents of public record. The first is the published VA Handbook 6500 (VAH 6500) which defined policy and procedures for systems within the purview of the VA (Department of Veterans Affairs, 2007). The second document is the Federal Information Security Management Act Assessment for FY 20011 commissioned by the VA Office of Inspector General (OIG) and performed by Ernst & Young in accordance with Federal Information Security Management Act (FISMA) guidelines (VA Office of Inspector General, 2012, p. i). 2. Identification of Controls This security profile presents one control function from three primary policy and procedure controls. These controls are ââ¬Å"System/New Technology Development Life Cycleâ⬠from Management Controls, ââ¬Å"Security Training, Education, and Awarenessâ⬠from Operational Controls, and ââ¬Å"Remote Accessâ⬠from Technical Controls. These controls are selected based on the lack of resolution based on information provided fiscal year 2006, 2010 (VA Office of Inspector General, 2011) and 2011 (VA Office of Inspector General, 2012) FISMA audits. 3. Management Controls The protection of systems via risk mitigation techniques are referred to as management controls. Management controls are designed to minimize risk associated with development process and systems implementation. 4.1. VAH6500 Section 6.a.(7) System/New Technology Development Life Cycle VAH6500 requires that any new technology undergo a systems development life cycle (SDLC) specific to the VA. The cycle consists of Initiation, Development / Acquisition, Implementation, Operation / Maintenance and Disposal. Systems must be able to encrypt/decrypt data. Systems not capable of this must receive a waiver from the OIG. 4.2. Implementation Assessment The SDLC program provided does not provide the necessary information for an effective program. No supporting material or references to NIST SP 800-64 Rev2 Security Considerations in the System Development Life Cycle or VAH 6500.5 Incorporating Security and Privacy into the System Development Life Cycle is made. 4.3. Implementation Impact The OIG 2011 FISAM Assessment indicates that ââ¬Å"FISMA Section 3544 requires establishing policies and procedures to ensure information security is addressed throughout the life cycle of each agency information systemâ⬠(VA Office of Inspector General, 2012, p. 9). Based on the lack of consistency in use of SDLC and change control, major security risks may go unnoticed. 4. Operational Controls Operational controls focus on techniques and procedures put in place by Information Technology staff or systems managers. The purpose is to increase security and provide deterrence via system controls. 5.4. VAH6500 Section 6.b.(11) Security Training, Education, and Awareness VAH6500 provides a concise policy which states any individuals that access sensitive information or systems must complete annual security training. Key persons with ââ¬Å"significantâ⬠roles must attend additional training. All training is monitored for completeness. Policy indicates before employees can use systems security training must be completed. 5.5. Implementation Assessment Policy indicates that fourteen key pieces of information must be covered before an individual is allowed to begin work. This training must also be refreshed annually. The tracking of this information is the responsibility of the local ISO (Department of Veterans Affairs, 2007, p. 57). 5.6. Implementation Impact The distributed manner of training management is not conducive to consistent security training. The OIG 2011 FISAM Assessment findings indicate a centrally managed training database be used to ensure personnel receive the proper training needed for their job function (VA Office of Inspector General, 2012, p. 15). 5. Technical Controls The technical control area focuses on minimizing and/or preventing access to a system(s) by unauthorized individuals via technical measures. The measures are designed to ensure the confidentiality, integrity and availability of a system(s) (VA Office of Inspector General, 2012, p. 54). 6.7. VAH6500 Section 6.c.(3) Remote Access Control VAH6500 relies on nineteen policy requirements to enforce technical control. VA policy states that no sensitive information may be transmitted via internet or intranet without proper security mechanisms that meet NIST FIPS 140-2 criteria (Department of Veterans Affairs, 2007, p. 61). Each department within the Agency is responsible for monitoring remote access and privilege functions. Access can be revoked by a supervisor or superior at any time. The remaining requirements cover contractor access, PKI certificate distribution and termination of accounts. System protection is the responsibility of the ISO for each area of access. 6.8. Implementation Assessment VAH6500 does not utilize NIST SP 800-46 Guide to Enterprise Telework and Remote Access Security. The OIG 2011 FISAM Assessment also indicates some remote access systems do not provide Network Access Control (NAC) to block systems that do not meet predefined security requirements (VA Office of Inspector General, 2012, p. 6). 6.9. Implementation Impact The diversity of ISO management practices coupled with a lack of specific procedures for management, auditing and access creates opportunity for security breaches. 6. Summary The three controls outlined in this document show the disparity between written policy, procedure, and implementation. In order for the VA to be successful in meeting the standards of future FISMA assessments, a fundamental change in operations within the VA is required. 7. Comments The multifaceted nature of operations within the VA requires guidelines that meet the needs of multiple departments within the Agency. All three controls discussed in this document have very broad definitions to accommodate the extensive variety of services the VA provides. This flexibility coupled with a drop in training acceptance, legacy systems (VA Office of Inspector General, 2012, p. 7) and the lack of an ââ¬Å"implemented components of its agency-wide information security risk management programâ⬠(VA Office of Inspector General, 2012, p. 3) will continue to limit future progress. These delay factors provide an understanding of why twelve recommendations from prior FISAM assessments remain open. Of the twelve recommendations listed in the VA FISMA FY 2011 report, only three have been closed, while three other recommendations have been superseded by new recommendations (VA Office of Inspector General, 2012, p. 19). The recent announcement of the Continuous, Readiness in Information Security Program (CRISP) seems to indicate a fundamental shift in the way the VA views security issues (United States Department of Veterans Affairs). In order for this program to be successful, this message must be understood and acted upon by all persons under the VA umbrella. 8.References Department of Veterans Affairs. (2007). VA Handbook 6500.
