Detect and break the cloud post-compromise attack chain (AWS / Azure / GCP) — per-stage CloudTrail / Activity-Log / Audit-Log detection signals and the preventive controls that close each step. Use for cloud detection engineering, hardening, remediation write-ups, or blue-team posture review of the lateral-movement -> privilege-escalation -> exfiltration -> evasion chain.

From the source SKILL.md

The blue-team counterpart to [cloud-containers](../cloud-containers/SKILL.md). For each attacker move — lateral movement, privilege escalation, data exfiltration, defense evasion — this skill gives the log event to alert on and the single control that removes the technique. Use it to turn an offensive cloud finding into a concrete detection and remediation.

What this skill does

Cloud Defense is a community-contributed Claude Code skill in the cloud-security sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/cloud-defense/ and loads when your prompt matches the skill's trigger.
