What we assess
Access settings
Privileged accounts, authentication controls and effective permissions.
Exposure and defaults
Management access, unnecessary features, debug settings and network rules.
Data and transport
Storage permissions, secrets handling and relevant TLS configuration.
Evidence and baselines
Logging controls, documented exceptions and applicability of an agreed hardening baseline.
Who it is for
Platform teams, IT owners and engineering leaders preparing a deployment, addressing audit observations or standardizing hardening.
Before we start
Identify the systems, versions, baseline and review objective. Share sanitized configuration exports or arrange least-privilege access securely. Agree how business-required exceptions should be evaluated.
Methodology
From scope to verified fixes.
Select a baseline appropriate to the actual platform; CIS guidance or relevant NIST controls may inform the review. Compare intended and effective settings, validate important deviations and separate accepted exceptions from unresolved risks. This is a scoped technical review, not a certification.
- Agree authorization, coverage, test limits and evidence handling.
- Discover and manually validate candidate weaknesses.
- Report confirmed findings, unverified observations and coverage limitations distinctly.
- Discuss remediation and retest the specified fixes within the agreed window.
Typical issues we look for
Examples of possible issues, not findings from R53SEC client engagements. Actual results depend on the system and scope.
- A default administration setting exposes functionality beyond the intended audience.
- An inherited permission grants broader access than the documented policy.
- A logging configuration omits an event needed to investigate a sensitive action.
What you receive
A baseline and applicability summary, evidence for deviations, business-context risk, proposed hardening changes and verification steps for approved remediation.
The report includes an executive summary, finding identifiers, severity rationale, impact, evidence, remediation and coverage limitations. CVSS is included where appropriate with its version, vector and assumptions. Retest scope, timing and commercial terms are agreed before work begins.
Questions about Security Configuration Review
Do you apply a benchmark without considering the environment?
No. Platform version, deployment model and business constraints affect applicability. Exceptions should have a documented rationale and owner.
Will configuration changes be applied during the review?
The assessment reports recommendations. Applying changes, testing compatibility and rolling back are separately agreed activities.
Does a passed review guarantee compliance?
No. A technical review addresses its agreed scope and evidence. Broader legal, contractual or certification requirements need their own evaluation.
