Seneca Global Services, LLC seeks a highly motivated Information Systems Security Officer (ISSO) to join our technical team supporting the National Cyber Range Complex (NCRC). The NCRC plays a critical role in enhancing the resilience of DoD systems and the effectiveness of U.S. cyber operations by delivering full-spectrum test and evaluation, workforce training, and mission rehearsal events.

• Review and analyze audit logs (e.g., Splunk, Windows EVTX, Linux syslogs) to detect potential anomalies or threats.
• Perform validation checks to ensure CM-approved software and antivirus definitions are installed on assigned systems.
