RE: Checkpoint smart defance as IPS

["Craig S. Wright" <craig.wright () Information-Defense com>]

"An IPS that decrypts SSL does not exist."
Of course it does. You decrypted e the key. This means that it is decrypted, scanned and re-encrypted. There are 
several products that can do this.

This does have a large CPU hit and it also means that the key is stored on the IPS and hence lowers security (as well 
as adding a few privacy concerns). Checkpoint has been able to do the SSL re-key bit since version 3.x. So this is not 
even novel on CP.

I first setup a reverse SSL proxy on Netscape proxy server back in the mid 90's. So this is not even new.

An IPS that decrypts SSL does not exist. Research SSL and how it works
and you will understand why.

A simple solution to the problem (based on what I gathered from the
snippets of conversation) is to place a proxy on the outside edge of
the network; force all clients to use proxy. The proxy will recreate
the SSL connection with a given webserver on the net for the client
and any traffic that is passed back to a client will be decrypted by
the proxy on its way back. On the inside edge of the proxy, place an
IPS inline to inspect the decrypted traffic.
