Of course you can detect a sniffer, but are you willing to pay the cost of doing so?You can't "detect a sniffer" from looking at the net; the only way you can try is to identify specific software indications of one being run on your machine. If it's run on a different machine, on one you can't check (perhaps on a palmtop someone has plugged into the net), then you can't detect it at all. Even if it's being run on your server, you can detect it if the author of the sniffer didn't know about, and defeat, the particular detection mechanism you use.
Incorrect - you can detect a sniffer - but it's not cheap. -- ----------------- \Management /\/| 216-686-0090 - PO Box 1480, Hudson, OH 44236 \ /\/ | Check out info-security heaven and test your system \/\ /\/ | for known vulnerabilities (1st time for free) at URL: \/Analytics| (scans deeper than SATAN or ISS) http://all.net:8080 ----------------- Read "Protection and Security on the Information Superhighway" John Wiley and Sons, 1995 ISBN 0-471-11389-1, 320 pp, $24.95
