• Establish AWS multi-account security governance using AWS Organizations, Control Tower, SCPs, account baselines, and security guardrails.
• Define cloud security standards, reference architectures, onboarding patterns, and reusable security controls for AWS workloads.
• Lead cloud security architecture reviews for new workloads, migration projects, digital platforms, APIs, and third-party integrations.
• Drive defense-in-depth and zero-trust principles across AWS identity, network, workload, data, logging, and monitoring layers.

AWS Identity & Access Security

• Govern IAM, IAM Identity Center, federation, role-based access, permission boundaries, and least-privilege access models.
• Define privileged access management controls for AWS administrators, DevOps teams, application teams, and third-party users.
• Review IAM roles, policies, service-linked roles, access keys, cross-account access, and temporary access patterns.
• Establish access review, entitlement governance, and remediation processes for AWS accounts and workloads.

• Implement and enhance AWS threat detection using GuardDuty, Security Hub, CloudTrail, AWS Config, Inspector, Macie, Detective, CloudWatch, and EventBridge.
• Establish centralized logging, immutable audit trails, security telemetry collection, SIEM integration, and alert routing for AWS environments.
• Define detection use cases for suspicious IAM activity, data exposure, network anomalies, malware indicators, vulnerable workloads, and misconfigurations.
• Drive alert tuning, incident response playbooks, cloud investigation procedures, and continuous improvement of cloud detection capabilities.
• Govern encryption, key management, secrets management, certificate management, and data protection controls using KMS, Secrets Manager, ACM, Macie, and S3 security controls.
• Define secure workload patterns for EC2, S3, RDS, Lambda, ECS/EKS, API Gateway, CloudFront, and serverless applications.
• Lead vulnerability management, patch governance, hardening baselines, container/image scanning, and remediation tracking for AWS workloads.
• Ensure backup security, recovery readiness, logging retention, and resilience controls are built into cloud workloads.

DevSecOps & Automation

• Integrate security into CI/CD pipelines, Infrastructure-as-Code workflows, cloud deployment processes, and release governance.
• Review Terraform and IaC templates for insecure configurations, excessive permissions, exposed services, weak encryption, and logging gaps.
• Implement automation for compliance checks, security alerts, remediation workflows, tagging governance, and operational reporting.
• Collaborate with DevOps, platform engineering, application, and infrastructure teams to embed cloud security into delivery practices.

Cloud Compliance & Risk Management

• Ensure AWS security controls align with MAS TRM, MAS Cyber Hygiene, PDPA, ISO 27001, NIST CSF, CIS Controls, and internal cloud security standards.
• Support cloud risk assessments, audit evidence collection, regulatory reviews, security exceptions, and remediation plans.
