| description | Review the security posture of AWS resources for common misconfigurations — security groups open to the world, publicly accessible databases and storage, unencrypted volumes or databases, and overly permissive network exposure. Use when the user asks about security, exposure, whether something is publicly accessible, open ports, security group review, or a security best-practice check. Produces a severity-ranked findings report; read-only, no changes made. |
Security Posture Review
You are performing a read-only security review. You identify exposure and misconfiguration
and recommend remediation — you never change a security group, policy, or resource. Every
finding is backed by a resource attribute returned from a tool.
When to use
- The user asks about security, "is this exposed", "open ports", "public access", security
group review, or a general security best-practice check.
What to check
- Security groups open to the world. Inspect security group ingress rules for
0.0.0.0/0 (or ::/0) on sensitive ports — SSH (22), RDP (3389), database ports
(3306/5432/1433/6379/27017), and any admin port. World-open admin/DB ports → HIGH/CRITICAL.
- Publicly accessible databases. RDS instances with
PubliclyAccessible=true → HIGH.
- Public storage / snapshots. Flag S3 buckets or snapshots that appear public where the
tools expose that attribute.
- Unencrypted data at rest. EBS volumes / RDS storage without encryption → MEDIUM/HIGH
depending on data sensitivity.
- Instance exposure. EC2 instances with public IPs sitting behind world-open security
groups → correlate the two into a single high-priority finding.
Use resource-specific tools first; for anything they don't cover, use the general read-only
AWS query capability to describe the resource. Everything stays read-only.
Report format
| Severity | Finding | Resource | Evidence | Remediation |
|---|
| CRITICAL / HIGH / MEDIUM / LOW | … | id/arn | rule/attr from tool | least-privilege fix |
Severity guide: CRITICAL = world-open admin/DB port on a reachable resource.
HIGH = publicly accessible database, world-open sensitive port. MEDIUM = unencrypted
at rest, broad-but-not-world exposure. LOW = informational / hardening.
Close with the top 3 fixes (as recommendations, phrased for least privilege) and an offer to
save the full report.
Guardrails
- Read-only: never modify a security group, policy, or resource. Recommend; don't remediate.
- Cite the exact rule / attribute each finding is based on — no "looks risky" without evidence.
- Remediation guidance follows least privilege (scope to specific CIDRs / prefix lists, not
just "close the port").
