Access Control Assessment

Access control rarely fails loudly. GSS assesses the technology and the procedures behind it against what actually happens on site, including the exposure created by the people the program is built to trust.

OPERATIONAL CONTEXT

Access control fails quietly, long before an alarm ever sounds

An access control program is the combination of credentialing, authorization, badge or biometric technology, and escort and visitor procedure that governs who is allowed where. Most failures in these programs aren't technology failures. They're administrative drift, such as authorizations that outlive their justification, escort practice that has quietly become informal, and exceptions that became the rule.

GSS assesses both the technology and the governing procedure, and checks each against observed practice on site rather than against the written policy alone. The evaluation is explicitly insider-threat aware, because the population with trusted access is also the population best positioned to defeat the controls meant to check them, and an assessment that ignores that isn't measuring the actual risk.

Findings translate into both technology recommendations and policy updates, coordinated with GSS's own policy development and program audit work rather than delivered as a standalone finding set.

METHODOLOGY
  1. 01

    Program & Procedure Review

    Credentialing, authorization, and escort procedures reviewed against governing documentation.

  2. 02

    Technology Assessment

    Badge, biometric, and access-control system performance evaluated against site requirements.

  3. 03

    Practice Observation

    Actual site practice observed against written procedure to identify drift.

  4. 04

    Insider-Threat Consideration

    Access population and authorization scope reviewed explicitly for insider-threat exposure.

  5. 05

    Authorization Audit

    Sample of active authorizations checked for currency and justification.

  6. 06

    Findings & Remediation Plan

    Gaps prioritized into a remediation plan with owners and timelines.

FAQ
Does this assessment cover cyber access controls too?The core assessment is physical access; where systems are digitally controlled, the work coordinates directly with cyber-physical and threat-hunting capability.
How do you find drift between written procedure and actual practice?Direct observation, sampling, and interviews on site. A paper review alone rarely surfaces where practice has quietly diverged from policy.
What does "insider-threat-aware" mean here specifically?The assessment evaluates whether trusted-access holders could themselves defeat the controls, not only whether the controls stop an outsider.
