Nicholas A. Southern, GRC and Cybersecurity Compliance Analyst

Skill Tree

Six years of allocated points. Main spec: GRC. Off-spec: operations. The build is deliberate.

Main specialization

GRC & compliance

Federal frameworks

Daily-driver frameworks from four years of DoD programs. Assessed, not just studied.

NIST 800-53 Rev 5NIST 800-171800-37 / RMFCMMC 2.0FedRAMPSTIG

Commercial frameworks

Commercial attestation work: SOC 2 program operations end to end, ISO alignment, trust reviews.

SOC 2 / TSCISO 27001:2022NIST CSF

Control lifecycle

The full loop, repeatedly shipped: gap analysis → remediation planning → narratives → evidence → POA&M closure.

GRC automation

The multiplier skill: evidence collection as code instead of screenshots-in-folders.

  • 5Wrote the package and defended it to the assessors. SOC 2, CMMC 2.0, NIST CSF.
  • 4Implemented end to end on a real program, full control lifecycle. NIST 800-53, RMF, ISO 27001.
  • 3Worked it regularly, not the whole lifecycle.
  • 2Studied and mapped, limited hands-on.
  • 1Familiar.

Self-rated, October 2026. The scale is mine; the evidence is on the resume and in the writing.

Second specialization

Security operations

Detection & response

Four years on a 24/7 watch floor. 1,000+ incidents from first alert to closed ticket.
