Leaking a private key is too high a price to pay for visibility into your SSL traffic, so take care! Think of this key as the combination to a safe guarding your valuables-make very sure that you only share it with trusted sources.

You must take extreme care with the handling of the private key – don’t leave copies of it lying around in temporary directories, make very sure it doesn’t end up on the Internet by accident, and make certain that the Sguil sensor you copy it to is as locked down as much as possible. With it, an attacker can decrypt the server’s SSL traffic or use it together with the server’s certificate in order to masquerade as a legitimate site. A word of warningĪs noted in the article on decrypting SSL, your server’s private key is a very sensitive thing indeed.

Windows also has the concept of a non-exportable private key a key stored in this way cannot normally be exported by the Windows certificate management tools (although tools like Jailbreak claim to be able to do it).

The file myExportedCertificate.pem will contain a block of text that looks like this:

When prompted, enter the password you gave when you exported the certificate and key. Once we’ve got the exported certificate, we can proceed to extract the private key using openssl like this:Ĭ:>openssl pkcs12 -in c:myExportedCertificate.pfx –out c:myExportedCertificate.pem -nodes In order to get the private key, we need to first export the certificate and key together as a PKCS12 file (read about that here). However, certain operating systems like Windows store certificates and keys in a “certificate store” instead of. pem file somewhere on the server, making it child’s play to copy it to the Sguil sensor. Getting the server’s private key onto the Sguil sensor could take a bit of work. The latter point means that the only SSL decryption we’re going to be able to pull off is decryption of traffic to and from servers that we own – we’re not going to be able to magically decrypt arbitrary SSL traffic (darn!) However, this is quite adequate from the viewpoint of intrusion detection and network forensics.

You must have access to the server’s private RSA key, and be able to copy it onto your Sguil sensor.

Fortunately, this is the most common form of key exchange for SSL based servers if you’re using DSA keypairs or the Diffie-Hellman key exchange mechanism you’re probably out of luck.

The server must be using the RSA key exchange mechanism (see here, bottom of page, and here, section F.1.1.2).

In a nutshell there are two conditions that must be met before we can proceed: We first need to understand a little about the mechanics of SSL decryption you can read about it in depth here.

Give your existing sensor platforms the means to decrypt the SSL sessions.Įach approach has its pros and cons this article will show you how to leverage the latter technique to restore the eyesight of your blind Sguil sensors.

Perform monitoring tasks on the webserver itself, perhaps by increasing the level of web and application logging.

You can then monitor the decrypted traffic between the loadbalancer and the webserver.

Terminate the SSL “in front of” the webserver, perhaps on a reverse-proxying loadbalancer or web application firewall.

There are a number of ways to get back the visibility stolen by SSL, including the following.

Also, if an incident is detected by other means (e.g., customer notification, web server log file monitoring, etc.) the investigative value of Sguil’s full packet capture is greatly diluted. No amount of tuning of the sensor’s Snort instance will help it detect intrusion attempts – the only traffic it will see is HTTPS. The webserver’s use of SSL means that network-based incident detection is problematic.
