I tune behavioral thresholds with analysts and turn telemetry into useful actions for Tier 3 and Tier 4 support . My work includes RMF artifact development , ATO lifecycle execution , and coordination with ISSOs, control owners, assessors, and government customers. I have performed hands-on reviews of Windows servers, Unix hosts, network appliances, and enclave services against DISA STIG requirements .
