You will monitor security tools and applications for malicious behavior, investigate alerts, and develop mitigation strategies while documenting all findings in a ticketing system with precise technical writing. The role involves collaborating with infrastructure, storage, database, and application teams to align monitoring with operational requirements during a transition to a secure cloud environment. Required skills include proficiency with Windows, Red Hat, AWS, Azure, and networking protocols like IDS/IPS systems and firewalls. You will utilize tools such as Splunk or Elastic for log analysis while applying DISA best practices to manage hardware security settings within a high-security, mission-critical network defense infrastructure.

  • Perform incident detection and response to identify and characterize anomalous activity within the enterprise network.
  • Monitor security tools and applications to investigate alerts and develop mitigation strategies.
  • Document all events and technical analyses in a ticketing system with accurate reporting.
  • Manage direct customer interactions and resolve issues independently as they are raised.
  • Improve internal processes and procedures to enhance overall team performance.
  • Perform regular system checks and ensure all documentation is complete and accurate.
  • Assist senior leadership with forecasting and modeling current cyber threats.
  • Coordinate with infrastructure, storage, and database teams to align monitoring with cloud migration requirements.

What we're looking for

  • Bachelor's degree and 2+ years of related experience; additional education or training may be considered in lieu of a degree.
  • Active TS/SCI security clearance required.
  • DoDD 8140 IAT Level II (or Level III) certification, such as Security+ CE.
  • Strong knowledge of Windows, Red Hat, Cloud (AWS, Azure), and networking protocols including IDS/IPS systems and firewalls.
  • Experience implementing application/hardware security settings using vendor and DISA best business practices.
  • Prior CND experience in a large enterprise or DoD/IC program environment (preferred).
  • Experience monitoring intrusion detection appliances, analyzing alerts, and documenting responses in ticketing systems (preferred).
  • Experience with SIEM tools like Splunk or Elastic, manual log review, and disaster recovery concepts (preferred).
