💼 [EC2.18] Security groups should only allow unrestricted incoming traffic for authorized ports

• ID: /frameworks/aws-fsbp-v1.0.0/ec2/18

Description

Security groups provide stateful filtering of ingress and egress network traffic to AWS. Security group rules should follow the principal of least privileged access. Unrestricted access (IP address with a /0 suffix) increases the opportunity for malicious activity such as hacking, denial-of-service attacks, and loss of data. Unless a port is specifically allowed, the port should deny unrestricted access.
