I'm concerned about the security of some critical EC2 instances on AWS. Is there a way to prevent these instances from being maliciously terminated, rather than just accidentally? Specifically, I'm looking for a method where two or more engineer accounts would need to approve the termination of these instances. Also, is there a way to set up automatic daily backups for these EC2s? Any guidance would be appreciated!

Just a quick note: enabling termination protection can be done with a simple command, and it's essential for critical instances. Daily backups through AWS Backup are very useful; you can select the instances you want to back up specifically.
You can enable termination protection on critical EC2 instances to help prevent accidental deletions. Also, using IAM policies with strict permissions can add an extra layer of protection. For automatic backups, consider setting up AWS Backup to create daily backups of your instances.
To enhance your security, you can use Service Control Policies to deny the termination of specific EC2 instances based on IAM roles. It’s a more granular approach that helps prevent unauthorized access. Also, definitely check out the AWS Backup service to automate your backup routine.
It's also important to limit IAM roles to the least privileges necessary. That way, even if someone tries to be malicious, their access is restricted. But, in any case, having regular backups should give you peace of mind!
A solid method is to integrate a CI/CD pipeline for managing EC2 instances. This way, only approved merges can trigger deletions, ensuring no one can delete instances directly without going through a review process.
