Information System Security Officer (ISSO)

Job Description

Responsibilities
Noblis is hiring an ISSO in Huntsville, AL to supporting the Threat Management Office (TSMO). The mission of the Threat Systems Management Office (TSMO) is to manage the Army Threat System Programs to include the total life cycle of threat systems for testing and training in the live, virtual, and constructive environments. TSMO designs, builds and tests representations of operational and emerging hostile systems with virtually identical performance capabilities that match the identified threat. TSMO ensures all threat systems are continually developed, upgraded, and/or modified and tested to reflect the current threat weapons systems platforms with state-of-the-art technology to support new and emerging DOD weapon systems. Additionally, TSMO conducts threat assessment and analysis in conjunction with the Army, Navy and other joint services operations.
TSMO utilizes a combination of simulators and simulation models, foreign material acquisition, commercial-off-the-shelf (COTs), and new development efforts to achieve its goal of providing threat relevant Electronic Warfare (EW), Information Operations (IO), integrated air defense (IADs), and command and control (C2) capabilities to support Operational Test and Evaluation (OT&E) events. These OT&Es include Network Integration Evaluations (NIEs), Combatant Commander events, as well as other testing and training events. TSMO requires a range of activities associated with conceptualizing, developing, and supporting the execution of testing events. Support is required to allow for more realistic threat representation testing for both hardware and/or software, and to upgrade threat systems and sub-systems with modern techniques that will offer superior threat representation testing against foreign threats. The TSMO requires the design of threat representations in order to reproduce live, virtual, and constructive threat simulations that satisfy the U.S. Army Test and Evaluation Command (ATEC) to support future test and training events.

In this role, the Information Systems Security Officer (ISSO) leads the Risk Management Framework process for systems assigned, and will support the full lifecycle of the Department of Defense (DoD) RMF process, from system categorization and control implementation through assessment, authorization, and continuous monitoring.

The ISSO will be responsible for preparing artifacts and documents to support government Authorization to Operate (ATO) activities. Additionally, the ISSO will conduct and/or support vulnerability and security compliance assessments using applicable tools, including ACAS/Nessus, SCAP Compliance Checker (SCC), STIG Viewer, and Evaluate-STIG. The Contractor shall analyze assessment results, document security deficiencies, support remediation activities, and maintain evidence necessary to demonstrate compliance with applicable NIST, DoD, DISA, and Army cybersecurity requirements.

Specific duties and responsibilities include:

Assist in the implementation of the required government policy (i.e., NISPOM, NIST, DoD), and documenting process activities.
Develop security artifacts to support the Information Assurance program to include System Security Plans (SSP), Plan of Action and Milestones (POA&M), System Diagrams, System User Guides, Privileged User Guides, and other documentation as needed.
Perform self-assessments of systems and networks within the environment, using passive evaluation audit tools such as: STIG Viewer, SCAP Compliance Checker (SCC), and active evaluations through ACAS/NESSUS.
Track enterprise reporting and efficiencies through automatic generation of required security compliance reports, integration of security tools, system documentation, and other artifacts utilizing the Enterprise Mission Assurance Support Service.
Track security updates for Windows and Linux-based operating systems, VMWare based products, and associated software applications to ensure compliance.
Periodically conduct a review of system audits, monitor corrective actions until all actions are closed, and identify deficiencies during RMF assessment activities.
