Security threats in e-commerce environment

The landscape of threats facing e-commerce systems.

Where attacks happen in a transaction

In a credit-card purchase: a keylogger on the client captures the card number (client threat); a hacker breaches the merchant server and steals millions of stored cards (server threat); a sniffer intercepts the card number in transit (communications threat).

Ponemon Institute surveys show that the most prevalent attack types include viruses, worms, Trojans, malware, web-based attacks, botnets, and phishing — affecting nearly every surveyed company.
