The classic techniques include things such as sniffing, which captures
all of the data coming from a connection and then analyzes

since they capture all of the data coming through a network, these
tools can be useful for mischief.

Sniffers might be a concern if you spend a lot of time surfing the Web

protections built into most Web sites that handle transactions,
there's a good deal of data that sniffers can't see, says Chris

He warns that it's far simpler for malicious cyber-types to write and
