• Understanding and managing the interaction between YAML configuration and its runtime engine, including rule loading, protocol decoding, and logging.
• Tuning IDS/IPS for optimal performance with NICs, including configuring Direct Memory Access (DMA), RSS queues, interrupt coalescing, and leveraging any NIC‑specific acceleration features.
• Collaborating with security teams to integrate IDS/IPS with SIEM and other security monitoring platforms.
• Troubleshooting installation and operational issues specific to IDS/IPS on Red Hat Enterprise Linux, addressing compatibility, kernel module requirements, SE‑Linux policies, and performance tuning.
• Identifying and mitigating common pitfalls encountered when deploying IDS/IPS in large‑scale enterprise environments, including package dependencies, system resource constraints, and NIC driver or configuration issues.
• Providing detailed documentation and runbooks for Suricata configuration, tuning NICs, and deployment processes.
• Staying current with Platform IDS/IPS Software releases, NIC driver updates, and community best practices for network interface tuning and IDS/IPS performance enhancement.

• Experience working with network IDS/IPS systems such as Snort, Suricata, or Corelight, including hands‑on management of YAML configuration files.
• Experience administering Red Hat Enterprise Linux (RHEL) systems, including package management such as yum or dnf, kernel module management, SE‑Linux configuration, and system optimization via Unix CLI and remote shell access vectors.
• Experience tuning Suricata for high‑performance packet capture with Napatech NICs or advanced network interface cards.
• Experience with NIC‑specific features such as DMA, Receive Side Scaling (RSS), interrupt moderation, and offload capabilities, and how to configure them for Suricata.
• Experience troubleshooting Suricata’s interaction with NIC drivers and kernel modules in an enterprise environment.
• Knowledge of configuration structure, syntax, and how it controls detection rules, logging, and output modules.
• Active TS/SCI clearance; willingness to take a polygraph exam.
• Associate’s degree and 5+ years of experience supporting IT projects and activities OR Bachelor’s degree and 3+ years of experience supporting IT projects and activities OR Master’s degree and 1+ year of experience supporting IT projects and activities.
