Securing EC3 Instances
Key Pairs
Key pairs allows you to connect EC2 Instances.
Key pairs can be created two ways:
- During EC2 Deployment
- Witihn the EC2 management console
Deleting Keys
Several reasons for deletion:
- Periodic cycling
- Employee with a key leaving
- Security event resulting in loss of keys or access via keys.
If a key id deleted you can no longer use it to access associated EC2 instances.
- This deletes the AWS copy of the key but does not delete the public key for the EC2 instances.
- For this reason if you have the private key you can still connect.
- Think of this as deleting the key from AWS registry, it does not delete from the instance!!.
You can recover from a lost pem file Recovery_from_lost_EC2_PEM_file
