Infrastructure Security

Overview

Infrastructure security covers the underlying environments used to run and connect workloads. It includes architecture, configuration, access control, segmentation, patching, encryption, monitoring, backup, capacity, physical safeguards, and administrative interfaces.

Weak infrastructure can compromise many applications at once through exposed management ports, excessive privileges, vulnerable hosts, shared secrets, flat networks, or unsafe dependencies. Cloud provider controls do not remove customer responsibility for deployed resources and identities.

Organizations should inventory assets, harden baselines, restrict administration, isolate critical services, monitor changes, patch vulnerabilities, and test recovery. Configuration should be reproducible and reviewed, while exceptions need owners, expiration, and compensating controls. Ownership and criticality should guide remediation priority decisions.

Infrastructure Security is a security mechanism or control discipline that protects computing, cloud, network, storage, identity, and platform foundations that applications and business services depend upon. Infrastructure security reduces shared failure paths by controlling assets, administration, configuration, segmentation, monitoring, patching, and recovery across foundational systems.

A production treatment of Infrastructure Security should test protection of computing, cloud, network, storage, identity, and platform foundations that applications and business services depend upon within the relevant asset, decision, or service state. The Infrastructure Security context record for computing, cloud, and network should preserve source data, configuration or policy version, responsible actor, exception, and outcome. Review of Infrastructure Security should determine whether safeguards addressing computing, cloud, and network changed exposure in practice, not merely whether a document or setting existed.

Quality review for Infrastructure Security should sample real cases involving computing, cloud, and network, compare expected and actual outcomes, and track unresolved exceptions until remediation is independently verified.
