Deleting a Security Group Rule

Scenarios

If you no longer need a security group rule to control the traffic to and from the instances in a security group, you can delete it.

Notes and Constraints

Note that deleting a security group rule may interrupt your services or cause network security risks.

Security group rules are like a whitelist. If there are no rules that allow or deny some traffic, the security group denies all traffic to or from the instances in the security group.
