✅ AWS Security Group Hardening – Reviewed and restricted inbound/outbound rules based on least privilege.
Objective:
Strengthen cloud infrastructure security by auditing and enforcing least privilege principles in AWS Security Group configurations.
Summary:
- Conducted a full review of existing Security Groups across development, testing, and production environments.
- Removed overly permissive rules (e.g., 0.0.0.0/0 for SSH/RDP) and restricted access based on IP, service, and environment role.
- Applied granular inbound and outbound rules specific to EC2, RDS, and Bastion Host traffic flow.
- Documented rule sets and implemented tagging for visibility and ongoing audits.
Key Highlights:
- Minimized attack surface by locking down unnecessary open ports
- Improved compliance posture through least privilege enforcement
- Standardized security configuration across all AWS environments
