• Support comprehensive cybersecurity monitoring and oversight of endpoint-security capabilities across the DHRA enterprise
• Validate that endpoint-security tools are properly deployed, configured, operational, and reporting required data
• Verify upstream rollup of endpoint-security data into applicable enterprise cybersecurity monitoring and reporting systems
• Validate endpoint-security reporting through the Defense Information Systems Agency Continuous Monitoring and Risk Scoring (DISA CMRS) capability, as applicable
• Maintain weekly records of endpoint-security data-rollup validation, coverage, configuration status, and identified deficiencies
• Identify and document systems or environments that are incorrectly configured, not reporting, or providing incomplete endpoint-security data
• Escalate endpoint-security configuration, connectivity, coverage, and reporting issues for corrective action
• Develop recommendations to optimize endpoint-security configurations to improve data collection, alert generation, visibility, and threat response
• Provide technically supported configuration recommendations to Government tool administrators for implementation
• Support network and server security scanning and validation activities associated with endpoint-security monitoring
• Perform compliance checks and cross-reference endpoint-security results against applicable Department of Defense, DHRA, and DMDC cybersecurity requirements
• Troubleshoot endpoint-security tool configuration, connectivity, deployment, data-rollup, and reporting issues
• Support Tier 2 troubleshooting and coordinate resolution with Government tool administrators, system owners, network and infrastructure teams, and cybersecurity personnel
• Evaluate recurring endpoint-monitoring results to identify coverage gaps, configuration trends, or systemic issues that may affect enterprise cybersecurity posture
• Document monitoring results, technical findings, corrective actions, and configuration recommendations
• Support improvements to endpoint-monitoring procedures, technical baselines, and cybersecurity monitoring practices
