How to Whitelist IP on AWS

To whitelist, an IP means that you are giving access to that IP for all the traffic. In AWS, it can be done using the security group rules. You can add a rule to whitelist any IP address of your choice. On the other hand, if you want to blacklist an IP address, you need to visit the network ACL service in AWS.
