Jeff, As far as I know these guys http://www.nitrosecurity.com/ pioneered the concept of the stackless control channel. Basically directing control packets towards an IP on the opposite side of the device. They wrote snort-inline and hogwash. Here's my feeble attempt at describing the process: Stackless Control Channel - AES encrypted packets directed through the appliance by attempting to send traffic to a host on the opposite side Recognizer - Code running on the appliance capable of interpreting encrypted control packets, decrypting them, and executing the embedded instructions Control Panel - GUI interface generates control packets and directs them through the appliance Each packet that passes through the appliance is checked for a "magic token" in the payload. If the token is found, the appliance will attempt to decrypt the payload following the magic token. If the token is found again immediately following the first magic token, the appliance knows it has found a control packet and processes the command. The innovative stackless architecture offers optimal placement for packet inspection and interdiction without necessitating network topology modifications. Bi-directional access means it's possible to manage the device securely from anywhere on the globe that supports Internet connectivity. Hope this helps. ----- Original Message ----- From: "Jeff McCarthy" <intel1914a () yahoo com> To: <focus-ids () securityfocus com> Sent: Wednesday, January 05, 2005 2:17 PM Subject: IPS with no IP address?
Hello, I recently sat in on an IPS vendor presentation. They stated that their IPS has 2 Ethernet interfaces, neither of which have IP addresses yet they can manage and monitor the device over IP. I thought this was interesting and somewhat unique. Are there any other vendors that do that? I know at least one other vendor has no IP on the interfaces listening to traffic but they have a seperate interface with an IP for management. Thanks, Jeff McCarthy USM __________________________________ Do you Yahoo!? Yahoo! Mail - Easier than ever with enhanced search.
