- Participate in/prepare for weekly Change Advisory Board (CAB) reviews and support change execution activities.
- Technical Security Standards (TSS) & Compliance Support
- Support compliance activities for security appliances (identify misconfigurations, assist with remediation planning/execution via CRs).
- Vulnerability Management Support (BAU)
- Support remediation efforts for lower-severity vulnerabilities (primarily P2/P3), escalating P1s to full-time team members per process.
- Threat Defense Support (as needed)
- Support Cisco threat defense activities, including IDS/IPS context and tasks such as Snort signature update support (where applicable).
- Documentation / Diagram Updates
