DB Networks Looks to Detect SQL Injection With New Appliance
The new Linux-powered appliance aims to limit the risk for SQL injection attacks.Year after year, in study after study, SQL injection is identified as a leading cause of data breaches and a top security vulnerability. There are a lot of vendors trying to help solve the problem, one of them being DB Networks, which announced a new security appliance this week designed to help detect the scourge that is SQL injection. DB Networks was founded in 2009 and has raised $7 million in funding to date, Steve Hunt, president and chief operating officer of DB Networks, told eWEEK. This week, the company is officially launching its new core intrusion detection system (IDS), the IDS-6300 hardware appliance. The IDS-6300 is a continuous monitoring device for SQL injection detection, according to Hunt. In a SQL injection attack, the attacker injects bad input into a database SQL statement in an effort to gain unauthorized access to the data. Hunt noted that one of the common ways that organizations try to defend against SQL injection is with a Web application firewall (WAF). However, Hunt said, attackers today can hide their attacks in ways that can get around a WAF, which is why the IDS-6300 takes a behavioral approach in contrast with the signature-based approach typically employed on a WAF. The IDS-6300 connects into the network via a Test Access Port (TAP) or Switched Port Analyzer (SPAN) port inside of an organization's existing network switching infrastructure. By using TAP or SPAN, the IDS-6300 is seeing a copy of the data traffic that is generated between the application server and the database server. As such, the IDS-6300 sits out-of-band on a network and does not impact the performance of the network or the database.
"We're modeling the behavior of the application traffic and then using advanced SQL injection behavioral analysis to detect attacks," Hunt said. "We're really looking for the difference between normal behavior and the abnormal behavior."
