Ensuring that security groups do not have ingress open to any ( means that the security groups have restricted access and only allow incoming traffic from specific IP addresses or ranges. Allowing open ingress to any IP address can pose a significant security risk as it may allow unauthorized access to AWS resources.


To ensure that security groups do not have ingress open to any (, organizations should implement the following remediation steps:

  1. Review Security Groups: Review all existing security groups in the AWS environment to identify any that have ingress open to any (
  2. Restrict Ingress Access: Update the security groups to restrict ingress access to specific IP addresses or ranges that require access to the resource. This should be done by updating the security group rules for the relevant security groups to include only the IP address or range that requires access.
  3. Remove Unused Rules: Remove any unused rules from the security groups to ensure that only necessary access is allowed.
  4. Regularly Audit and Review: Regularly audit and review security groups to ensure that ingress access is restricted and there are no open rules.

By implementing these remediation steps, organizations can help ensure that security groups do not have ingress open to any ( and that access to AWS resources is restricted to only necessary IP addresses or ranges. This helps to reduce the risk of unauthorized access to AWS resources and enhances the overall security posture of the AWS environment.
