RE: Checkpoint smart defance as IPS

Not at all. Your comment was:
"An IPS that decrypts SSL does not exist."

This is blatantly false. IDS, IPS, Wireshark even all have SSL decryption
capabilities. There is no requirement for a separate proxy. 

Checkpoint has this capability. NO extra proxy. You seem to be missing that
distinction.

You are saying the same thing me and anyone else who has posted on the  
topic is saying, you're just using different words. You should read  
the whole thread before you make comments.

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.

I think that the client needs to buy a real IPS which can also
open the encrypted traffic.

Not sure what you mean by this? An IPS which can decrypt encrypted
traffic on the fly?
