Why we read it this way (6)
Location is not specified in the posting; no CBSA or state could be determined. Given Peraton's national-security government-contracting focus, the role is likely in the DC metro area or another cleared-work hub, but this is not stated.
The degree requirement allows substitution: a Bachelor's + 8 years is the baseline, but 4 additional years of relevant experience or specialized training may be accepted in lieu of the Bachelor's degree. The minimum formal degree is set to Bachelor's because that is the stated baseline; the experience-in-lieu clause is noted here.
The IAT Level II certification is a hard gate; CompTIA Security+ is the preferred option within that gate. Other IAT Level II-qualifying certs (e.g., CySA+, CCNA Security) would also satisfy the requirement.
The desired certifications list (CASP+, CISM, CISSP-ISSAP, CISSP-ISSMP, FITSP-D, GCIA, GCSA, GICSP, GSEC, GDSA, GMON, CCSP, CISSO, Cloud+, CSSLP) appears under 'Desired Qualifications' and is therefore preferred. CISSP is listed as the primary with the most common peers in alternatives; the full list is too long to enumerate individually.
The 8-year minimum experience figure reflects the Bachelor's-degree path (8+ years); the Master's path requires 6+ years and the PhD path 3 years. The lowest stated minimum across all paths is 3 years, but the most common baseline (Bachelor's) is 8 years, which is used for the overall years minimum.
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.
