About Ayuba Obamina

I am an Information System Security Officer (ISSO) with 6+ years of experience supporting FISMA compliant systems across federal, healthcare, and corporate environments. I specialize in owning security posture, maintaining continuous ATO, and helping organizations survive audits without operational disruption.I have served as primary ISSO and ATO point of contact for multiple systems, leading RMF lifecycle activities including SSP development, security control assessments, POA & M remediation, and continuous monitoring. I work closely with system owners, ISSMs, privacy officers, and government stakeholders to translate regulatory requirements into practical security outcomes.My background includes hands-on experience with eMASS, NIST SP 800-53 FISMA reporting, and vulnerability management using tools such as Nessus and Splunk. I am equally comfortable operating in cleared federal environments and supporting business-focused security governance in commercial settings.I bring a risk-based, operational mindset—focused on protecting systems, reducing findings, and keeping missions moving.Clearance: Active SecretFocus Areas: ISSO | RMF | ATO | GRC | Audit Readiness | Cloud Security Governance
