Rule Description
To comply with CISA Cyber Essentials guidelines, it is important to have a backup plan in place for EC2 instances. This backup plan ensures that critical data stored on the instances is protected and can be recovered in the event of data loss, corruption, or system failure.
Troubleshooting Steps
- 1.
Identify the EC2 instances that do not have an active backup plan.
- 2.
Verify if the instances have important data that needs to be backed up.
- 3.
Check if the necessary permissions are in place to create and manage backups.
- 4.
Ensure that there is enough storage capacity available for storing backups.
