Overview
Implementation and evolution of AWS security and governance controls.
Context
Cloud security required controls across identity, configuration, workloads, network, logging and organizational governance.
Challenge
Connect prevention, detection and response in a sustainable operational model.
My role
- IAM, access policies, Organizations and SCP
- GuardDuty, Inspector, AWS Config and monitoring
- Event analysis, investigation and troubleshooting
- Security, cloud and operations integration
Architecture
The approach grouped controls across three complementary capabilities: prevent, detect and respond.
Technical decisions
- Security by Design
- Preventive controls at the appropriate level
- Detective signals with operational context
- Response supported by logs, investigation and remediation
Security & governance
Prevent: IAM, SCP and network controls. Detect: GuardDuty, Inspector, Config and monitoring. Respond: investigation, logs, troubleshooting and remediation.
Engineering challenges
The challenge was reducing noise, preserving context and turning findings into risk-proportionate action.
Results
- More coherent security coverage
- Closer SecOps and Cloud Engineering integration
- A better foundation for investigation and control evolution
