We are in search for a Linux System Administrator - Active TS/SCI Required to work at our customer site at the National Maritime Intelligence Center, Suitland, MD. In this role you will provide operations, engineering, and technical support services and associated supplies to support certain AWS resources, Red Hat Enterprise Linux servers, Splunk software, Python scripting language, REGEX parsing, and .xml presentation format development, architecture, administration, and Risk Management Framework (RMF) requirements and operations of the Hopper ISC CYBERDEP Security Information Event Management and NAVINTEL Enterprise Audit Capability (SIEM/NEAP).

THE MISSION

The Hopper Information Services Center (ISC) is an IT service provider for the Office of Naval Intelligence (ONI) and for 70+ Navy Intelligence Community (IC) ashore organizations across the globe with the mission to deploy and operate classified information systems, networks, communications systems, and cybersecurity capabilities. Within Hopper ISC, the Cybersecurity Department (CYBRDEP) is comprised of four divisions (Defensive Cybersecurity Operations [N62], Cybersecurity Mission Operations [N63], Assessment & Validation [N64], and Cybersecurity Engineering [N66]), and these divisions collectively secure, protect, assess, and monitor fielded Information Technology (IT) capabilities against a full range of internal and external threats.

Security Information Event Management (SIEM) platforms support threat detection, compliance, and security incident management through the collection and analysis (both near real-time and historical) of security events, as well as a wide variety of other event and contextual data sources. The core capabilities are a broad scope of log event collection and management, the ability to analyze log events and other data across disparate sources, and operational capabilities (such as incident management, dashboards, and reporting). Enterprise Audit is an activity that “provides authorized personnel with the ability to review and examine any action that can potentially cause access to, generation of, or affect the release of classified or sensitive information.”
