    Removes one or more rules from a security group.

    Explanation:

    The command ec2-revoke-security-group-ingress is used to remove specific inbound (ingress) rules from an Amazon EC2 security group.

    • Security groups act as firewalls that control traffic to and from EC2 instances.
    • When a rule is revoked using this command, it means that the specified protocol, port, or IP range will no longer be allowed for incoming traffic.
    • This helps in restricting access to EC2 instances by modifying security group rules.
