TDI's mission is to create the world's most advanced cybersecurity ecosystem. Learn more about our products & services today to get started.

Tetrad Digital Integrity (TDI) is a leading-edge cybersecurity firm with a mission to safeguard and protect our customers from increasing threats and vulnerabilities in this digital age.

TDI is seeking a Vulnerability Analyst to join the Compartmented Enterprise Services Office (CESO) effort. This program is establishing a modern secure web service (SWS) operation as part of a state-of-the-art, highly automated platform capable of supporting a rapidly expanding customer population. Apply today to become part of the Leidos team assisting CESO as it migrates to a high security cloud environment, providing vulnerability management, risk assessment, and compliance services that protect the integrity of the platform throughout its lifecycle.

Multiple positions are available, including day-shift opportunities in Arlington, VA, and night-shift opportunities in San Antonio, TX. All positions are fully onsite and require an active TS/SCI clearance.

RESPONSIBILITIES:

  • Responsible for meeting both regulatory (Legal and Mandated Requirements) and non-regulatory (Real-World Threat Reduction) compliance demands across the CESO environment.
  • Assist in the management and maintenance of the IAVA (Information Assurance Vulnerability Alerts) program for CESO systems.
  • Manage and enforce information security policies, and train and educate end-users on proper security practices.
  • Conduct security and risk assessments using established frameworks (e.g., NIST, RMF, Common Criteria), mitigating risk via security controls and testing and evaluation to certify and accredit commercial security products used within the CESO platform.
  • Develop, update, organize, maintain, and track RMF documentation using information obtained from the customer.
  • Ensure privacy of data throughout its lifecycle; perform vulnerability management (scanning, assessment, reporting, and mitigation verification), business continuity, and disaster recovery activities.
  • Coordinate with infrastructure, storage, database, and application teams to align vulnerability management activities with CESO's operational and compliance requirements.
  • Maintain documentation, operational procedures, and compliance reports supporting CESO's secure cloud migration.
  • Responsible for a combination of duties to protect information and maintain security controls across the CESO system, site, or program in order to reduce risk.

QUALIFICATIONS:

  • Candidate must currently have a TS/SCI with the ability to obtain and maintain a CI Poly.
  • DoDD 8140 compliant certification, at minimum IAT Level II (e.g., Security+ CE), at start.
  • Bachelor's degree and 2+ years of related IT security experience; additional experience, education, or training may be considered in lieu of degree.
  • Experience with the Defense Information Systems Agency (DISA) security model, controls, and authorization processes for standard computing systems and cloud computing environments across the Department of Defense.
  • Experience conducting activities associated with Information Assurance Vulnerability Alerts (IAVAs), including those issued by the Cybersecurity and Infrastructure Security Agency (CISA).
  • Experience creating and maintaining Information Assurance documentation, including Security Control Traceability Matrices (SCTMs), Risk Assessment Reports (RARs), Security Assessment Reports (SARs), and Plans of Action and Milestones (POA&Ms).
  • Experience with ACAS and SIEM tools.
  • Experience implementing application and hardware security settings in accordance with vendor and/or DISA best business practices.
PAY RANGE:

The anticipated salary range for this position is $110,000 - $120,000. This range is a good-faith estimate and not a guarantee of compensation. Final compensation will be based on factors including experience, education, skills, geographic location, internal equity, market data and applicable contract requirements, and may fall outside the posted range.
