The Senior Information Security Analyst is a highly experienced cybersecurity professional responsible for ensuring the confidentiality, integrity, and availability of an organization's information systems. This role serves as a subject matter expert on all matters of operational cybersecurity, leading efforts to secure systems, manage risks, and ensure compliance with all governing policies and regulations. The Senior Analyst is responsible for implementing and managing the security posture of assigned systems throughout their lifecycle, from initial authorization to decommissioning. This individual works with system owners, administrators, and users to enforce security controls, respond to threats, and maintain the formal Authority to Operate (ATO).

compliance and prepare the system for security assessments and
audits.
Vulnerability Management and Remediation:
- Perform regular vulnerability scanning of systems and networks using
approved tools (e.g., ACAS/Nessus).
- Analyze scan results, prioritize vulnerabilities based on severity and
mission impact, and coordinate with system administrators to ensure
timely remediation.
- Track and report on remediation progress, and develop Plans of Action
and Milestones (POA&Ms) for vulnerabilities that cannot be
immediately fixed.
Security Operations and Monitoring:
- Monitor security logs and alerts from various sources (e.g., SIEM,
firewalls, endpoint security tools) to identify, analyze, and respond to
suspicious activity.
- Serve as a key player in the security incident response process,
including identifying the source of a threat, containing the impact, and
leading eradication and recovery efforts.

- Develop, implement, and enforce information security policies,
procedures, and guidelines based on DoD, DAF, and NIST standards.

- Promote security awareness by providing training and guidance to all
system users.
