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.

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... ------------------------------------------------------------------------ Test Your IDS Is your IDS deployed correctly?
