Centralized AWS Security Monitoring
Engineered centralized security monitoring into an external SIEM, across the AWS landing zone, facilitating incident response and hardening the cloud
The Challenge
- Centralized Monitoring: Security logs across the AWS landing zone were unmanaged with no detection rules
- The platform engineering team lacked the capacity to deploy AWS security services beyond basic configurations
- Incident response without an enterprise SIEM was slow and error-prone
The Solution
- Deployed AWS security tools across landing zones, using infrastructure as code
- Centralized security logs into hardened S3 buckets and routed them into an external SIEM
- Standardized the detection engineering process with rules deployed as code
- Implemented security controls and hardening, supporting GRC efforts
The Impact
- Centralized security visibility across the AWS landing zone, via enterprise SIEM integration
- The incident response time accelerated, and false positive alerts reduced, resulting in better threat detections
- Improved compliance score on CIS and other industry-specific regulations
- Security deployments became repeatable and standardized, through infrastructure as code
