The alert came at midnight. A strange login attempt from an unfamiliar network. No one had seen it before. By dawn, the team knew: their infrastructure access security review was overdue.
An infrastructure access security review is more than a checklist. It is the direct analysis of every path into your systems, mapped against who can reach them, how they authenticate, and what happens when things go wrong. The review exposes gaps in access control, identity management, network segmentation, and audit logging. It measures your current state against hard policies and compliance requirements. It forces you to face the truth about your exposure.
Start with a complete inventory. Catalog every bastion host, VPN, Kubernetes admin console, cloud IAM role, and privileged account. Trace the chain from user to resource to confirm no undocumented access routes exist. Every link must have strong authentication—multi-factor should be mandatory for all elevated privileges.
Next, verify network isolation. Public endpoints should be minimal, monitored, and behind hardened gateways. Internal services should not be accessible without strict role-based credentials. Audit firewall rules and security groups, removing legacy entries that no longer serve a valid business purpose.
