Position Summary

ECS is seeking a Network Security Engineer (CDAP) - Journeyman to support the Army National Guard (ARNG) Enterprise Network Operations and Cybersecurity Support (ENOCS) program. This role supports Task 3 - Cybersecurity Operations Support by helping implement and sustain network security monitoring capabilities that defend ARNG classified and unclassified network environments across the DoDIN-Army-NG area of responsibility. The Network Security Engineer (CDAP) integrates data from network sensors and boundary protection devices, assists with correlation rule tuning and ingestion troubleshooting, validates detection coverage under senior direction, and documents configuration updates that support reliable, compliant cybersecurity operations. The position works as part of the broader ENOCS cyber team supporting Security Operations Center activities, monitoring and analysis, vulnerability management, and DCO-IDM execution.

Please Note: This position is contingent upon contract award.

This position contributes to a mission environment that delivers DoDIN services and cyber defense support to more than 120,000 users and approximately 141,000 endpoints across about 2,800 sites in 54 states and territories, including support for Title 10 and Title 32 missions. The role operates within an enterprise cybersecurity architecture that includes integrated SIEM/C2C/DLP analytics, USIEM detection engineering, IDS/IPS, EDR, Zeek metadata, Sysmon-based ATT&CK analytics, and coordination with NETCOM Global Cyber Center and DISA DCDC. The work directly supports ARNG mission continuity, mobilization readiness, domestic emergency response, and the protection of both NIPRNet and SIPRNet-connected operations through sustained monitoring reliability and improved detection visibility.

Responsibilities

  • Integrate data from network sensors and boundary protection devices to support CDAP network security monitoring across ARNG classified and unclassified environments.
  • Assist with tuning correlation rules and analytics under senior direction to improve detection fidelity, monitoring effectiveness, and coverage validation.
  • Troubleshoot event ingestion issues affecting security monitoring data streams and support restoration of reliable telemetry into enterprise monitoring platforms.
  • Validate detection coverage for monitored network traffic and document gaps, updates, and recommended adjustments to support DCO-IDM operations.
  • Maintain documentation for configuration changes, monitoring updates, and performance optimization activities to support compliance alignment and operational traceability.
  • Support monitoring reliability for security capabilities that feed centralized visibility through integrated SIEM/C2C/DLP analytics and USIEM-enabled operations.
  • Coordinate with senior cybersecurity personnel supporting SOC monitoring, detection engineering, and network security operations to align sensor data and monitoring outputs.
  • Help optimize monitoring performance for boundary protection technologies such as firewalls, IDS/IPS, VPN, and other enterprise network equipment identified within the ENOCS environment.
  • Contribute to cybersecurity operations conducted in coordination with the NETCOM Global Cyber Center and DISA DCDC by supporting accurate, sustainable network security data integration.

ECS gained market share in 2011 in the Department of Defense and Federal spaces through both organic and acquisition growth. In May, ECS completed its first strategic acquisition with the purchase of OAK Management, Inc., a leading provider of marine environmental services, ship systems engineering, maritime consulting and platform acquisition management. The OAK acquisition kicked off ECS’ intention to add tactical acquisitions as a part of its long term strategy to supplement and expand upon organic growth and to build enterprise value. ECS closed out 2011 with the acquisition of Paradigm Technologies, Inc. The Paradigm transaction added approximately 200 employees to ECS’ existing 900+ employees. Paradigm also added new Defense clients for ECS, including the Missile Defense Agency, the Navy’s Program Executive Officer for Integrated Warfare Systems, the United States Marine Corps, and the U.S. Marshals Service.

In 2012, ECS completed the acquisition of iLuMinA Solutions, Inc. iLuMinA brings large-scale Enterprise Resource Planning (ERP) software implementation and infrastructure design and development to ECS’ expanding capabilities.
