As the ISSO, you are responsible for the day-to-day security operations of one or more information systems and for maintaining the system’s Authorization to Operate (ATO) under the DoD Risk Management Framework (RMF). You will serve as the primary point of contact for the ISSM, the Authorizing Official’s representative, and the engineering team on all matters of system security.

You will track vulnerabilities, IAVMs, and STIG compliance; manage POA&M closure; coordinate audits and assessments; and review system changes for security impact. You translate policy (NIST 800-53, CNSSI 1253, DoDI 8500.01, 8510.01) into clear engineering guidance.
You proactively solve unusual and/or complex problems with little or no direction given and operate effectively in a fast-paced technical environment supporting senior military leadership.
