What it is
Cloud security is the practice of protecting cloud-based applications, data, and infrastructure. It covers identity management, encryption, network security, compliance, and access control across cloud environments.
Why cloud & devops developers need it
A misconfigured cloud resource can expose data to the entire internet. Understanding cloud security practices — least-privilege access, encryption, and security auditing — is essential for any cloud or DevOps role.
What to learn
IAM best practices: least privilege, MFA
Encryption: at rest and in transit
Network security: VPCs, security groups, NACLs
Secrets management: Vault, AWS Secrets Manager
Security auditing and compliance scanning
Container security: image scanning, runtime policies
Incident response in cloud environments
Practice project
Security Audit
Audit your cloud environment: review IAM policies for least privilege, enable encryption on storage, configure VPC security groups, set up CloudTrail logging, and document your security posture.
