1. A protocol management system coupled with a local network, the local network interfaced with an external network, the protocol management system comprising:
- a gateway configured to receive all instant message traffic flowing into and out of the local network;
a blacklist comprising a list of links;
a security module configured to check each instant message coming into the local network via the gateway, determine whether the instant message includes a Universal Resource Locator (URL), if so determine whether the URL is in the blacklist and send a challenge to a sender associated with the instant message when it is determined that the URL is not in the blocklist.
