Security Audit Report (sample)

SECURITY AUDIT REPORT
Scope: production infrastructure and primary backend service
Report date: [today]

EXECUTIVE SUMMARY

The scan output indicates a generally well-configured production environment with four findings warranting action. Three are high priority and can be addressed within the current sprint. One is medium priority and represents an operational hygiene investment for Q2. No critical findings were identified that would require immediate emergency remediation.

Highest-priority finding: the production database subnet currently accepts SSH traffic from the public internet on port 22. This is a high-severity, common misconfiguration and should be remediated today.

FINDINGS, PRIORITIZED

[HIGH] Finding 1. Public SSH exposure on production database subnet.
Severity rationale: the database tier should never be directly reachable from the public internet on a management port. Attackers routinely scan for open SSH on cloud provider IP ranges.
Evidence: nmap output shows port 22 open on 52.xx.xx.0/24 subnet.
Remediation: Remove the allow-all ingress rule on the database security group. Require SSH access to traverse a bastion host in the public subnet. Enable AWS Systems Manager Session Manager as a preferred alternative, eliminating the need for SSH entirely.
Estimated effort: 2-4 hours, including testing that legitimate access paths still work.

[HIGH] Finding 2. One transitive dependency with known RCE vulnerability.
Severity rationale: an RCE (remote code execution) CVE in a transitive dependency allows an attacker to run arbitrary code on your backend under certain conditions.
Evidence: npm audit flags lodash 4.17.15 (via an indirect dependency). The fixed version is 4.17.21 or later.
Remediation: Upgrade to latest minor release. Verify no breaking changes to your direct dependency that transitively requires lodash. Run your full test suite.
Estimated effort: 1-2 hours, assuming no test-suite regressions.

[HIGH] Finding 3. Three IAM roles with AdministratorAccess policy attached.
Severity rationale: overpermissioned IAM roles are the largest category of cloud-related breaches. Any compromise of credentials associated with these roles would grant full account access.
Evidence: IAM CSV shows three roles (dev-deploy, backup-service, support-debug) with the managed AdministratorAccess policy attached.
Remediation: Replace AdministratorAccess with specific policies scoped to each role's actual need. The dev-deploy role likely needs ECR + ECS + a narrow set of S3 actions. The backup-service role needs S3 read/write to specific buckets. The support-debug role likely needs read-only access to CloudWatch and a narrow set of RDS actions.
Estimated effort: 4-8 hours, including identifying the minimum viable policies for each role.

[MEDIUM] Finding 4. MFA not enforced on IAM users.
Severity rationale: without MFA, any leaked long-lived access key grants account access. MFA prevents this.
Evidence: IAM CSV shows 8 IAM users, only 3 have MFA devices registered.
Remediation: Enforce MFA via IAM policy on the remaining 5 users. Rotate their access keys after MFA enrollment.
Estimated effort: 2-3 hours including user communication.

KNOWN-CVE MATCH DETAILS

Direct-dependency audit findings: 0 high, 0 moderate (clean).
Transitive-dependency audit findings: 1 high (Finding 2 above), 3 low.
The three low-severity transitive findings are all in development-only dependencies (linters, test runners) and do not reach production code. Track but do not block on them.

REMEDIATION ROADMAP

This week (Findings 1, 2): Close public SSH exposure. Upgrade lodash. These are independent and can be worked in parallel by two engineers.

Next week (Finding 3): IAM role scoping. This is the most interesting engineering work and requires identifying each role's actual access pattern. Plan 1-2 days of engineer time.

This quarter (Finding 4): MFA rollout. Straightforward but requires user coordination.
