Duration
6–9 weeks
Team
Cloud security engineer, DevOps, Security lead
Situation
Multiple cloud accounts created by different teams led to inconsistent security posture, drifted IAM permissions, and cost spikes.
Objectives
- Establish a baseline security posture across environments
- Reduce identity and configuration risk (least privilege + guardrails)
- Improve visibility and make security repeatable
What We Did
Baseline Controls
Used CIS Benchmarks as a reference for secure configuration.
IAM Cleanup
Inventoried permissions, introduced RBAC, removed broad privileges, and added break-glass access.
Logging and Detection
Centralized security logs and alerts for risky changes (public buckets, firewall rules, etc.).
Challenges & Solutions
Fear of outages
Solution: Used staged rollouts and "monitor-only" periods before enforcing guardrails.
Ownership gaps
Solution: Created an ownership registry—every account had a named owner.
Tool fragmentation
Solution: Consolidated controls into standard templates.
Key Outcomes
- Significant reduction in high-risk misconfigurations
- Faster root cause analysis due to consistent logging
- A repeatable baseline for future environments
Deliverables
- Cloud posture report + prioritized backlog
- IAM refactor plan
- Standard baseline templates and onboarding checklist
