CCAR Accomplishment
[Context] As the lead INFOSEC analyst for a 15,000-endpoint enterprise network, [Challenge] I was tasked with reducing the agency's mean time to detect (MTTD) security incidents from 72 hours to under 24 hours following an OIG audit finding. [Action] I designed and deployed a SIEM correlation engine with 200+ custom detection rules, integrated threat intelligence feeds from CISA, and established a 24/7 SOC rotation. [Result] Reduced MTTD to 4.2 hours (94% improvement), identified and remediated 3 critical zero-day vulnerabilities before exploitation, and received the Secretary's Award for Cybersecurity Excellence.
