# Cloud Security Cloud security posture assessment skill for detecting IAM privilege escalation, public storage exposure, network configuration risks, and infrastructure-as-code misconfigurations. This is NOT incident response for active cloud compromise (see incident-response) or application vulnerability scanning (see security-pen-testing) — this is about systematic cloud configuration analysis to prevent exploitation. --- ## Table of Contents - [Overview](#overview) - [Cloud Posture Check Tool](#cloud-posture-check-tool) - [IAM Policy Analysis](#iam-policy-analysis) - [S3 Exposure Assessment](#s3-exposure-assessment) - [Security Group Analysis](#security-group-analysis) - [IaC Security Review](#iac-security-review) - [Cloud Provider Coverage Matrix](#cloud-provider-coverage-matrix) - [Workflows](#workflows) - [Anti-Patterns](#anti-patterns) - [Cross-References](#cross-references) --- ## Overview ### What This Skill Does This skill provides the methodology and tooling for **cloud security posture management (CSPM)** — systematically checking cloud configurations for misconfigurations that create exploitable attack surface.

What does the cloud-security skill do?
Use when assessing cloud infrastructure for security misconfigurations, IAM privilege escalation paths, S3 public exposure, open security group rules, or IaC security gaps. Covers AWS, Azure, and GCP posture assessment with MITRE ATT&CK mapping.
How do I install it?
Run `npx skills add alirezarezvani/claude-skills --skill cloud-security --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From alirezarezvani/claude-skills, a repository with 23,791 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
