Cloud Security Posture Management (CSPM) is a category of tooling that continuously inspects cloud environments for misconfigurations, policy violations, and compliance drift. The reason it exists is blunt: a large share of cloud breaches trace back to simple mistakes like a public storage bucket, an over permissive IAM role, or a database exposed to the open internet, and CSPM catches those before an attacker stumbles onto them.
What makes the cloud hard is velocity. Developers create and destroy resources constantly, and a manual security review is stale the moment it is written. CSPM tools plug into cloud provider APIs to get near real time visibility and flag anything that deviates from a defined baseline. The pitfall is alert overload. Point one of these at a large estate and it will surface thousands of findings, so teams that do not prioritize by real exposure end up ignoring the tool entirely.
Why does CSPM matter for the CISSP exam?
CSPM connects to Domain 3 (Security Architecture and Engineering), with ties to assessment and testing. Candidates should understand the shared responsibility model and continuous compliance monitoring in dynamic environments. See Domain 3: Security Architecture and Engineering.
