Estimated from BLS employment for this occupation and area, per-skill prevalence across our listing corpus, and published wage benchmarks — as of Jul 28, 2026. It is a model, not a headcount.
Why we read it this way (7)
The posting is titled 'entry level' but requires a minimum of 8 years of experience with a BS/BA (6 with MS/MA, 3 with PhD, or 4 additional years in lieu of a degree) — the actual requirements support a Senior-level classification despite the advertised framing.
The clearance gate is TS/SCI with the ability to obtain a polygraph (hard required); an active TS/SCI with Poly is listed under Desired Qualifications as a preferred upgrade.
CISSP or Security+ is listed in the required qualifications section; both are captured as alternatives on a single must-have skill.
Cisco Packet Tracer (or similar) and DoD 8570.01-M IAT I/II certifications appear under Desired Qualifications and are marked preferred accordingly.
The role's primary day-to-day work is systems/network administration and end-user support (provisioning, troubleshooting, hardware/software maintenance), which maps to 15-1244. The security clearance requirement and CISSP/Security+ certification create some overlap with 15-1212, noted as the runner-up.
Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): DoD 8570.01-M IAT.
Requires a TS/SCI clearance — the cleared population is a small fraction of this occupation, so the real candidate pool is materially smaller than the estimate below, which does not model clearance.
