Breach Security (www.breach.com) offers a product called BreachView SSL,
whose sole purpose is to passively decrypt SSL traffic for an IDS/IPS to
inspect. The product works as a preprocessor, sending the IDS both the
encrypted traffic as well as a corresponding packet containing the
decrypted content. An IDS is then able to analyze the traffic and
report on threats within encrypted traffic.
The product is available as either an appliance or a software plug-in
for Windows or Linux environments. Please see
http://www.breach.com/products/breachview-ssl.html for more details or a
free evaluation.

Subject: Re: How to monitor encrypted connections...
If the traffic is encrypted then it IDS will first have to decrypt the
traffic. The IDS will have the keys to decryopt the traffic. This kind
of design is certainly possible in HIPS where for SSL traffic keys can
be uploaded, IPS will first decrypt the trafic and then forward the
traffic to exploit/vulnerability specific rules. However it will be
computationaly expensive.
Still working on my IDS/IPS project...
When browsing some IDS/IPS vendors' datasheets, >I noticed that some of
them
claimed being able to monitor encrypted traffic.
Could someone provide me with some insight on >what is currently
possible (and already
implemented) and what are the eventual limita...
