Cloud Security Posture Management (CSPM) continuously checks your cloud config against best practices and benchmarks - because the #1 cause of cloud incidents is a misconfiguration, not a zero-day.
The misconfigs that hurt most
- Public storage - S3 buckets / blobs open to the internet (data exposure).
- Over-permissive IAM - wildcard
*actions/resources, unused admin roles, long-lived keys. - Public management surfaces - databases, RDP/SSH, or dashboards exposed to 0.0.0.0/0.
- No MFA / root usage - especially root account activity or missing MFA on privileged users.
- Disabled logging - CloudTrail/Activity logs off or not centralized.
- Unencrypted data - at rest or in transit where it should be encrypted.
How CSPM helps
Tools like Prowler, ScoutSuite, Trivy and cloud-native posture services scan your accounts and score them against CIS benchmarks, flagging drift as it happens. The goal is to catch the open bucket before an attacker does.
Make it operational
- Run posture scans continuously (not once a year) and alert on new criticals.
- Fix the highest-impact classes first: public data, IAM privilege, exposed management.
- Pair posture (config) with detection (behavior) - CSPM finds the open door; your CloudTrail detections catch someone walking through it.
