• Support the development and maintenance of endpoint alert triage procedures, escalation playbooks, and response runbooks, contributing practical observations and lessons learned from daily monitoring activities.
• Assist in identifying and documenting false positive alert patterns, supporting senior engineers in refining detection rules, alert thresholds, and EDR platform tuning to improve alert fidelity and reduce analyst fatigue.
• Monitor endpoint protection platform health and availability, identifying and escalating platform performance issues, service disruptions, and coverage gaps that may impact the program's ability to detect and respond to endpoint threats.

Vulnerability & Patch Management Support

• Assist in the execution of endpoint vulnerability scanning activities, supporting the scheduling, execution, and result collection of regular vulnerability scans across managed endpoints using enterprise vulnerability scanning platforms.
• Support the analysis and triage of endpoint vulnerability scan results, assisting senior engineers in identifying, categorizing, and prioritizing vulnerabilities based on severity, exploitability, and asset criticality under defined risk-based prioritization criteria.
• Assist in tracking and reporting on endpoint patch compliance status, monitoring patch deployment progress across managed endpoints and identifying systems with outstanding critical and high-severity patches requiring escalation.
• Support coordination with system administrators and desktop support personnel to facilitate timely endpoint patch deployment, providing technical assistance and escalation support as needed.
• Maintain accurate and current endpoint vulnerability and patch compliance records in the program's vulnerability management tracking system, supporting audit readiness and compliance reporting activities.

Endpoint Hardening & Compliance

• Assist in the implementation and validation of endpoint hardening standards, supporting the application of DISA STIGs, CIS Benchmarks, and client-specific security baselines across managed Windows, Linux, and macOS endpoint environments.
• Support configuration compliance scanning activities, assisting in the execution and analysis of Security Content Automation Protocol (SCAP) scans and configuration compliance assessments across managed endpoints.
• Assist in tracking and reporting on endpoint configuration compliance status, identifying non-compliant endpoints and supporting remediation activities to bring endpoints into compliance with applicable security baselines.
• Support the development and maintenance of endpoint hardening documentation, including hardening guides, configuration baseline specifications, and compliance reporting templates.

Incident Response Support

• Support cybersecurity incident response activities involving endpoint security events, assisting senior analysts and engineers in evidence collection, endpoint isolation, malware containment, and remediation activities under defined incident response procedures.
• Assist in the collection and preservation of endpoint forensic evidence, supporting chain of custody procedures and forensic acquisition activities under the guidance of senior digital forensics or incident response personnel.
• Document incident response activities accurately and completely in the program's ITSM platform, ensuring incident records contain sufficient detail to support post-incident review, root cause analysis, and lessons learned activities.
• Support post-incident review activities, contributing endpoint security observations and technical findings to root cause analysis discussions and corrective action development.

Compliance & Documentation Support

• Assist in maintaining endpoint security compliance documentation, including security control implementation evidence, configuration compliance records, vulnerability remediation tracking data, and audit artifacts, supporting the program's ATO and continuous monitoring obligations.
• Support the development and maintenance of endpoint security standard operating procedures, operational runbooks, and knowledge base articles, contributing practical operational knowledge to the program's documentation library.
