As an Information Security Analyst Sr Principal, the work you do at GDIT will directly support the mission of our federal customer. You will play a critical role in achieving and sustaining the Authorization to Operate (ATO) for enterprise systems within a federal government agency. This position places you at the intersection of cloud technologies and Commercial Solutions for Classified (CSfC), contributing to an innovative and high-visibility program.

You will develop Security Impact Analyses (SIA) for system changes and update key security documentation, including the System Security Plan (SSP), Information Security Contingency Plan, and other required security artifacts. You will coordinate with Federal Government officials to obtain and maintain the system's Authorization to Operate (ATO).

You will ensure compliance with federal regulations and privacy requirements. Responsibilities include conducting investigations of information system security violations and incidents, security vulnerabilities, and reporting findings to management as necessary.
