description: |
|
|
|
|
|
Check Amazon EC2 security groups for inbound rules that allow unrestricted RDP access and restrict access to trusted IPs.
|
|
|
|
|
impact: |
|
|
|
|
|
Unrestricted RDP access increases the risk of unauthorized access and potential breaches.
|
|
|
|
|
remediation: |
|
|
|
|
|
Modify the EC2 security group rules to limit RDP access (TCP 3389) to known, trusted IP addresses or ranges.
