Rule Description: ELB Application Load Balancer Deletion Protection for NIST 800-53 Revision 5
The ELB (Elastic Load Balancer) Application Load Balancer Deletion Protection is a security measure that prevents accidental or unauthorized deletion of application load balancers within an AWS (Amazon Web Services) environment. This feature ensures the availability and continuity of services by reducing the risk of unintentional deletion or disruption.
Deletion Protection acts as a safeguard against accidental deletions caused by human error, malicious intent, or other unforeseen circumstances. When enabled, this protection feature restricts the deletion of Application Load Balancers, enforcing additional steps to complete deletion tasks.
By implementing this rule, businesses and organizations can enhance the security and stability of their AWS infrastructure by mitigating the risk of accidental data loss or downtime.
Troubleshooting Steps:
In case you face any issues or encounter errors while configuring or enabling ELB Application Load Balancer Deletion Protection, follow the troubleshooting steps below:
- 1.
Verify IAM (Identity and Access Management) permissions: Ensure that the user or role attempting to enable deletion protection has the necessary IAM permissions to perform this action. The required permission is
.elasticloadbalancing:ModifyLoadBalancerAttributes - 2.
Check load balancer status: Confirm that the load balancer you want to enable deletion protection for is in a functioning state and available. Deletion protection cannot be enabled for load balancers that are not active or experiencing any other issues.
- 3.
Verify AWS CLI (Command Line Interface) configuration: Ensure that you have valid AWS CLI credentials configured on your system. You can check this by running
and verifying the access and secret keys, along with the default region.aws configure - 4.
Review AWS documentation and forums: If you encounter any specific errors or difficulties, refer to the official AWS documentation on Elastic Load Balancing and Deletion Protection. Additionally, the AWS Developer Forums can provide insights and solutions from the community.
Necessary Codes:
To enable ELB Application Load Balancer Deletion Protection, you will need to run the following AWS CLI command:
aws elbv2 modify-load-balancer-attributes --load-balancer-arn <load_balancer_arn> --attributes Key=deletion_protection.enabled,Value=true
Replace
<load_balancer_arn>Step-by-Step Guide for Remediation:
Follow these step-by-step instructions to enable ELB Application Load Balancer Deletion Protection using the AWS CLI:
- 1.
Open the terminal or command prompt on your local machine.
- 2.
Ensure that you have the AWS CLI installed and configured with appropriate credentials.
- 3.
Run the following command to enable deletion protection for the desired ELB Application Load Balancer:
aws elbv2 modify-load-balancer-attributes --load-balancer-arn <load_balancer_arn> --attributes Key=deletion_protection.enabled,Value=true
Replace
<load_balancer_arn>- 1.Verify the response from the command to ensure that the modification was successful.
Once the deletion protection is enabled, any attempts to delete the load balancer will require additional confirmation steps, reducing the risk of accidental or unauthorized deletions.
Always ensure that you follow the best practices for managing and securing AWS resources. Regularly review and update your security measures to align with the latest industry standards and guidelines, such as NIST 800-53 Revision 5.
