Best Practices for Securing AWS Environments for a New AWS Security Specialist

Question

**Hello AWS Community,**

I’m Mahesh Shukla, and I’m currently preparing for the AWS Security Specialist certification. As I dive deeper into cloud security, I’m eager to learn from the experienced professionals here.

Could you please share some best practices for securing AWS environments? Specifically, I’m interested in:

Essential security measures every AWS setup should have.
Tools and services within AWS that are particularly effective for maintaining security.
Common pitfalls to avoid when securing an AWS environment.
Any advice, resources, or experiences would be greatly appreciated. Thank you in advance for your help!

Hello.

I recommend that you start by reviewing the Well-Architected Framework's security documentation.  
This document includes best practices for securing your AWS accounts and a description of the AWS services you use to protect them.

> Tools and services within AWS that are particularly effective for maintaining security.

You can enable AWS Security Hub and check your score to see how well your AWS account settings align with security best practices.  
Check results in AWS Security Hub are displayed as a score. Based on these results, you can ensure a certain level of security by solving problems one by one and increasing your score.
