description: |
|
|
|
|
|
Identifies unrestricted inbound access to PostgreSQL databases in Amazon EC2 security groups, which can expose databases to security risks.
|
|
|
|
|
impact: |
|
|
|
|
|
Unrestricted access on TCP port 5432 increases vulnerability to unauthorized access and potential data breaches.
|
|
|
|
|
remediation: |
|
|
|
|
|
Restrict inbound traffic to PostgreSQL servers by setting stringent rules in EC2 security groups, limiting access to specific IPs or ranges.
