Instance and Container Security
Securing and accessing EC2 instances as well as ECS or EKS clusters within AWS requires a strategic approach to ensure both robust security measures and efficient accessibility. Here are some best practices, starting with EC2.
EC2 Security
EC2 instances reside within a VPC (Chapter 2, Virtual Private Cloud), so they are able to benefit from VPC security measures such as security groups and network access control lists (NACLs) to limit access. You can also use IAM roles to further control what other AWS services can be used from within the EC2 instance and to grant access to users. You should also consider using encryption of the data that is held on the EC2 instances to ensure it cannot be accessed without authorization. Now take a look at the main areas of security you have available:
- Security groups: Implement security groups to control inbound and outbound traffic to EC2 instances. Define rules based on IP addresses, ports, and protocols...
