About Information System Security Officer

  Description: This position requires the candidate to function as the Information System Security Officer (ISSO) for multiple programs and performs as a technical liaison in support of the security standards and requirements relevant to the NIST Risk Management Framework (RMF) Step 1 thru Step 6 for the information systems. The desired candidate will possess a working understanding of the NIST 800-53 Security and Privacy Controls for Federal Information Systems and Organizations combined with a high degree of technical skills obtained through systems engineering or systems administration. The candidate must have working experience with the development, implementation, and maintenance of either the Linux and/or Microsoft Windows operating systems and supporting applications.

  The ISSO is responsible for the oversight of the information system’s security posture with emphasis placed on the application and sustainment of the security controls. In doing so, the primary functions include development and maintenance of the System Security Plan (SSP), Plan of Action and Milestones (POA&M), and Security Controls Traceability Matrix (SCTM) as primary RMF deliverables. The ISSO also performs routine system auditing as well as vulnerability and compliance scanning throughout the entire lifecycle of the system.

  • Intelligence Community Directive 503 (ICD-503)

  • DCSA Assessment and Authorization Process Manual (DAAPM)

  • National Industrial Security Program Operating Manual (NISPOM Chapter 8)

  • Joint Special Access Program (SAP) Implementation Guide (JSIG)

This ensures that the security controls are: (1) being met and (2) implemented correctly with respect to the environment. Deficiencies and weaknesses identified throughout the process will be reported back to the ISSM.

  Primary support activities include:

  • Perform routine self-inspection reviews of the information systems.

  • Perform comprehensive investigations of computer security incidents and ensuring proper measures are taken post discovery of the incident / event.

  • Manage and execute the information security continuous monitoring requirements relevant to the system.
