Deleting a Security Group Rule

Scenarios

If your security group rule is no longer required, you can delete it.

Notes and Constraints

Security group rules use whitelists. Deleting a security group rule may result in ECS access failures. Security group rules work as follows:
  • Inbound rule: If an inbound request matches the source in an inbound security group rule with Action set to Allow, the request is allowed.
  • Outbound rule: If the destination of an outbound security group rule with Action set to Allow is 0.0.0.0/0, all outbound requests are allowed.
