The Shared Responsibility Model
Cloud security operates on a shared responsibility model. The cloud provider (e.g., AWS, Azure) is responsible for the "security *of* the cloud" – protecting the infrastructure that runs all the services. The customer is responsible for "security *in* the cloud" – securing their data, applications, and configurations. My expertise lies in mastering the customer's side of this model to build secure and compliant cloud environments.
Key Areas of Focus
Identity & Access (IAM)
Crafting least-privilege IAM policies, managing roles and users, and securing root accounts with MFA.
Network Security
Configuring VPCs, Security Groups, and Network ACLs to create secure, segmented network architectures.
Data Protection
Implementing encryption at rest (KMS, S3 Encryption) and in transit (TLS) to protect sensitive data.
Infrastructure as Code (IaC)
Scanning Terraform and CloudFormation templates for misconfigurations before they are deployed.
Container Security
Securing container orchestration platforms like EKS and GKE, and implementing container image scanning.
Logging & Monitoring
Configuring CloudTrail, CloudWatch, and VPC Flow Logs for threat detection and incident response.
Posture Management (CSPM)
Using tools to continuously monitor for misconfigurations and compliance deviations in the cloud environment.
Serverless Security
Hardening serverless functions (e.g., AWS Lambda) by securing their execution roles and dependencies.
My Approach to Cloud Security
I view the cloud not as a risk, but as an opportunity to build security in from the ground up. My approach is automation-centric, leveraging Infrastructure as Code (IaC) to create reproducible, secure, and auditable environments. I have significant hands-on experience with AWS, where I've designed secure multi-account strategies, implemented fine-grained IAM policies, and built automated guardrails to prevent common misconfigurations. I use tools like Prowler and custom scripts to audit environments for compliance and security best practices, ensuring that the dynamic nature of the cloud does not compromise its security posture.
