      ISS.net Sniffer FAQ ( original, circa 1996 ) -- nowhere to be found

    • The Following is susceptible to sniffing ( its passwd is clear text )
      • telnet, pop3, imap, ftp, snmp, nntp

    • Using Secure pop3 and Secure IMAP
      • will (?) prevent the the sniffer from seeing your login and passwd
      • will NOT prevent the the sniffer from reading your email in clear text
        when it travels around the world and comes into or leaves your mail server

    • More importantly, ALL unencrypted data is sniffable ( human readable )
      • send and receive only encrypted data for a trivial solution against sniffing

    • Using easy to guess login and passwd mitgates any encryption
      • it takes a few seconds or minutes to guess your passwd
        in the "100,000 word dictionary"

    • How do you know if someone is sniffing all your data
      • your competitors will sniff the incoming email to your mail servers

    • They can sniff ALL of your data, login, passwd and all emails
      • they can sniff ALL your data from all the routers you passed thru
      • they can sniff ALL your data from your ISP
      • they can sniff ALL your data from your colo
      • they can sniff ALL your data from your local network
      • they can sniff ALL your data from your wireless network
      • they can sniff ALL your data from your vpn connections at home
      • they can sniff ALL your data from the airport, coffee shops, etc
      • they can sniff ALL your data from outside your office or home

    Keyboard Sniffers - Loggers
    • if they installed a keyboard logger, you're dead ... gameover .. encryption will NOT help either since they can see your passphrase
      • if they installed the keyboardlogger remotely, you have other very serious securityproblems

    • if they have physical access, game over... just pull the plug and walk out with the PC or laptop with important data on it
