description: |
|
|
|
|
|
Checks for inbound rules in EC2 security groups allowing unrestricted access (0.0.0.0/0) to TCP port 443, increasing exposure to potential breaches.
|
|
|
|
|
impact: |
|
|
|
|
|
Unrestricted access to TCP port 443 can lead to unauthorized data exposure and increases the risk of security breaches.
|
|
|
|
|
remediation: |
|
|
|
|
|
Restrict inbound traffic on TCP port 443 to only necessary IP addresses, adhering to the principle of least privilege.
