Re: Blocking phishing URL's

Since there was some interest how we utilize our Packetlogic to block phishing links I wrote up a small how-to.

We are using our Packetshaper  (Packetlogic) to redirect users to a landing page on campus alerting them they have 
clicked on a phishing link. It's a manual process, but I set up a rule and only need to add the url. Works pretty well, 
plus I see how many hits the rule gets.

Greetings!

I've been asked to investigate what other institutions are doing to block access to URL's at the edge (i.e. block 
connections when people click on a URL, despite virtual hosting or fastflux DNS).

Feel free to respond privately.  Thanks.

Best,
Cathy
