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

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

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

• Located in: 💼 Elastic Compute Cloud (EC2)

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.
