• Document and report anomalies to appropriate channels for further investigation and notification.
• Document vulnerable findings and provide recommendations through appropriate channels that increase both security and operational capacity of the respective network.
• Recommend improvements to current operations for potential incorporation into the overall program.
• Collaborate with cross-functional teams to support incident response, system hardening, and policy development as needed.
• Additional duties, as assigned.
• 5-10% CONUS Travel

Requirements:

• Active TS clearance with SCI eligibility required
• Bachelor s or Master s degree in a technical field such as computer science or cybersecurity; additional direct operational experience may be considered in lieu of degree.

• Practical experience with firewalls, network TAPs, IDS/IPS, endpoint protection, and other network defense technologies
• Adept in evaluating network protocols utilizing network analyzers, such as Wireshark, Tshark, and tcpdump
• Experienced in analyzing network datasets, including Zeek and firewall logs, to support threat hunting and security investigations.
• Experienced in leveraging data analysis platforms, such as Splunk, Kibana, and Arkime, to detect and analyze anomalous network activity
• Proficient in triaging Suricata alerts, tuning rules, and creating custom detections.
• In-depth understanding of network vulnerabilities and misconfigurations
• Experience working within the framework of a CONOPS or similar operational document
• Awareness of DoD cybersecurity frameworks (e.g., RMF, CMMC, NIST 800-53) and their application in secure system design and monitoring.
• Knowledge of common enterprise network architectures and defense mechanisms
