OCTO touts near‑perfect uptime and extensive vulnerability scanning while acknowledging ongoing risks
Summary
Stephen Miller told the committee OCTO's NOC achieved 99.8% network uptime, resolved most tier‑1 tickets within 30 minutes, and conducted nearly 12,000 vulnerability assessments in FY25 while stressing persistent cyber threats and the need for continued investment.
Stephen Miller told the committee that OCTO's network operations center maintains high availability for district systems and serves as the first line of defense for cybersecurity incidents.
"99.8% network uptime means systems are available whether the demand is at 10AM or 10PM," Miller said, describing monitoring of thousands of components and rapid ticket resolution. He said the NOC resolved roughly 92% of tier‑1 tickets within 30 minutes and that OCTO conducted nearly 12,000 vulnerability assessments in fiscal year 2025 to identify and remediate weaknesses.
Miller framed the effort as essential infrastructure for public services: reliable communications and data services underpin 311 calls, benefits processing, school systems and emergency response. He also warned that the District faces ongoing threats from sophisticated actors and daily probe attempts, and emphasized continuous monitoring, multifactor authentication and zero-trust principles as the center of OCTO's security program.
Committee members asked for documentation of contingency and disaster recovery plans and for more transparency on uptime and incident metrics; Miller said those plans are reviewed annually with HEMA and that OCTO would provide additional details on recovery capabilities.
