Cloud attack emulation and CSPM: are your controls actually tested?

TL;DR: CSPM and CNAPP find misconfigurations and runtime issues, but they do not prove how an attacker could chain them into a breach, according to OFFENSAI. The core lesson is that cloud security maturity now depends on demonstrated exploitability, not just posture visibility.

By the numbers:

• Cloud-first or cloud-native enterprises now represent over 80% of organisations, making cloud control validation a mainstream governance problem.
• Only 5.7% of organisations have full visibility into their service accounts, leaving machine identity governance incomplete.
• 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface.

Questions worth separating out

Q: What breaks when cloud posture tools are used without attack validation?

A: Posture tools identify misconfigurations, but they do not show whether those weaknesses can be chained into privilege gain or data exposure.

Q: Why do over-permissive cloud identities make CSPM findings more dangerous?

A: Because CSPM often flags the configuration, while identity misuse is what turns that configuration into impact.

Q: How do security teams know whether cloud access policy is actually working?

A: They should test whether policy decisions are traceable from discovery to approval to revocation.

Practitioner guidance

• Validate exploitable cloud paths, not just misconfigurations Test whether exposed buckets, permissive roles, and weak secrets can be chained into privilege gain and data access.
• Add identity-centric checks to cloud validation Include access keys, service accounts, and IAM role scope in every cloud attack test so the exercise reflects how attackers actually move through cloud environments.
• Use runtime findings to narrow the remediations queue Separate posture noise from issues that an attacker can reach in a live environment.
