AWS Security Best Practices

Amazon Web Services provides powerful tools for building secure infrastructure, but proper configuration is essential to avoid common, costly mistakes.

Hardening IAM

Follow the principle of least privilege by granting only the permissions each user or service needs, enable multi-factor authentication for all accounts, and avoid using the root account for daily operations.

Securing S3 Buckets

Publicly exposed S3 buckets are a leading cause of AWS data breaches. Block public access by default, enable bucket policies and encryption, and regularly audit bucket permissions.

Network and Resource Protection

Use security groups and network ACLs to restrict traffic, isolate resources in private subnets within a VPC, and encrypt data using AWS KMS wherever sensitive information is stored.

Monitoring and Logging

Enable AWS CloudTrail to log all account activity and AWS Config to track configuration changes, giving security teams the visibility needed to detect and investigate suspicious behavior.
