AWS Security Starter Pack: 5 Essential Tools

Source: Dev.to

Most cloud breaches aren’t the result of sophisticated attacks or genius hackers. They’re often caused by simple misconfigurations—like a public S3 bucket or an IAM role with overly permissive permissions. AWS provides built‑in tools to prevent these issues; the challenge is that many teams don’t enable them.

GuardDuty

GuardDuty monitors your AWS environment 24/7. It ingests data from CloudTrail, VPC Flow Logs, and DNS logs to establish a baseline of normal activity and alerts you when anomalies are detected.

Security Hub

When you run multiple security tools, findings can become scattered across different services. Security Hub aggregates those findings into a single dashboard, giving you a unified view of your security posture.

IAM Access Analyzer

Permissions can quickly become tangled. Cross‑account access granted for a project may linger long after the project ends, leading to unnecessary exposure. IAM Access Analyzer helps you identify and remediate such overly permissive policies.

CloudTrail

CloudTrail records API activity across your AWS account, providing an immutable audit log. It’s essential for forensic investigations and for understanding who did what, when.

Config

AWS Config continuously records configuration changes and evaluates them against your defined rules. It helps you catch drift—such as temporary security‑group openings or unencrypted resources—before they accumulate into larger compliance gaps.

Why All Five?

These tools are intentionally overlapping:

• GuardDuty detects active threats in real time.
• Security Hub offers a consolidated security overview.
• IAM Access Analyzer prevents permission sprawl.
• CloudTrail supplies the forensic trail when incidents occur.
• Config stops misconfigurations from building up.

Running all five provides comprehensive coverage at a minimal cost compared to the expense of a breach. If you’re scaling your AWS footprint, these basics are essential for a solid security foundation.
