On another engagement with DISA for Cyber Threat Emulation and Inspection Support, Gunnison developed, reviewed and updated security policies and plans to conduct audits of security programs for defense agencies and other DISA customers. Our team deployed on behalf of DISA to conduct security audits and perform vulnerability tests. All audits and tests were conducted against and in accordance with FISMA, NIST and DOD security guidelines. We identified and reported all findings through formal reports and briefings to all stakeholders, providing recommendations for mitigating vulnerabilities. Gunnison performed follow up assessments to ensure that mitigation strategies had been implemented and delivered the desired security results. Gunnison performed and developed multi-level insider threat detection and prevention inspection programs for the Department of Defense Information Network (DODIN) at the enterprise level.
