AWS Security
- IAM (Identity & Access Management): Every AWS service uses IAM to authenticate and authorize API calls.
- I - Authentication (caller identity)
- AM - Authorization (permissions)
- So, we need to create all IAM user accounts including admin user.
- Enable MFA (Multi-factor-authentication) - username/apssword + Authentication code from a device.
- AWS STS (Security Token Service) - it is a way of restrictiong long standing access key. To use temporary security credentials in code, we programmatically call an AWS STS API like AssumeRole and extract the resulting credentials and session token. We can then use those values as credentials for subsequent calls to AWS.
- Logging and Monitoring:
- Enable CloudTrail - it provides who did what from where and when.
- Enable GuardDuty - it is a security monitoring service. It addresses issues like escalations of privileges, uses of exposed credentials, and it can detect compromised EC2 instances serving malware or mining bitcoin.
- Build automated notifications via SNS (Simple Notification Service) with the inputs from CloudTrail, CloudWatch, or GuardDuty. We can receive the notifications on Slack or Jira. We can get notified at a root login event, security group changes etc.
- Infra Security:
- Patch Manager - it is a feature of AWS Systems Manager.. It automates the process of patching managed instances after scanning against the patches, policies, and configurations of an instance.
- Reduce target surface of attacks - via private subnets, security groups, or bastion hosts / vpn.
- Create an infra resilient to DDos - CloudFront (accepts only well-formed contents), AWS WAF / Shield.
- Data Protection: - Transit (data that travels through an email, web, collaborative work applications such as Slack or Microsoft Teams, instant messaging)
and at Rest (files stored on file servers, records in databases).
- Encryption via KMS
- AWS Secret Manager - do not store secrets in plain-text, rotate secrets, manage access with fine-grained policies.
- Incidence Response:
- Have a incidents plan and test it - high level roles and responsiblities, identify, contain, respond, and recover.
- Backup and restore - EC2 (EBS snapshot), S3 versioning.
