Tips: Best Practices for The Other AWS Amazon EC2 Resources
In addition to the aws_default_vpc, AWS Amazon EC2 has the other resources that should be configured for security reasons. Please check some examples of those resources and precautions.
aws_default_vpc
Ensure to avoid using default VPC
It is better to define the own VPC and use it.
aws_network_acl_rule
Ensure your network ACL rule blocks unwanted inbound traffic
It is better to block unwanted inbound traffic.
aws_ebs_volume
Ensure to use a customer-managed key for EBS volume encryption
It is better to use a customer-managed key for EBS volume encryption. It can be gain more control over the encryption by using customer-managed keys (CMK).
aws_instance
Ensure to avoid storing AWS access keys in user data
It is better to avoid storing AWS access keys in user data. `aws_iam_instance_profile` could be used instead.
aws_security_group
Ensure your security group blocks unwanted inbound traffic
It is better to block unwanted inbound traffic.

Explanation in CloudFormation Registry
Specifies a target for your Traffic Mirror session.
A Traffic Mirror target is the destination for mirrored traffic. The Traffic Mirror source and the Traffic Mirror target (monitoring appliances) can be in the same VPC, or in different VPCs connected via VPC peering or a transit gateway.
A Traffic Mirror target can be a network interface, or a Network Load Balancer.
To use the target in a Traffic Mirror session, use AWS::EC2::TrafficMirrorSession.
