Abuse-Detection Security

A potential threat to any website is a “denial of service” (DoS) attack where the attacker issues a large number of requests for service. Perpetrators of DoS attacks typically target sites or services hosted on high-profile web servers such as banks and credit card payment gateways.

DoS attacks can slow the response time to legitimate visitors, overwhelm the database server, and generate excessive emails that interfere with normal operation. To prevent these attacks, B2C Service provides web form and survey security through CAPTCHA, which automatically requires human validation when abuse is suspected. CAPTCHA validation is typically triggered only if there appears to be active abuse of a website. However, you can customize CAPTCHA requirements from the customer portal.
