With the recent “denial of service” attacks wreaking havoc on online banking sites, concerns over security are increasing. Banks have been unable to defend themselves against these attacks, and it’s creating a customer-service nightmare when websites go down. Hackers have identified a weakness in security technology and are taking full advantage of it.
Attackers use a classic diversion tactic, explains the FBI in a recent warning, by inundating sites with over twice the amount of traffic they’re equipped to handle. Criminals have developed refined botnets—a “network of computers infected by a program that communicates with its creator in order to send unsolicited emails, attack websites, etc” (Dictionary.com)—to generate bogus traffic that debilitates website functionality. When current security measures are overloaded as they sort through vast amounts of phony traffic, hackers are able to make fraudulent transactions unnoticed. The websites are also temporarily disabled, making customers unable to do their online banking.
Increasing bandwidth to handle more traffic could be a solution, but it comes with its own set of problems. From a budgetary standpoint, it would be quite costly to purchase, and the extra bandwidth would be wasted during periods without attempted attacks. Technology professionals in the banking industry clearly face a challenge when it comes to implementing security measures to protect websites from “denial of service” attacks that have been largely successful so far.
Technology professionals in the banking industry are challenged by recent and largely successful “denial of service” cyber attacks. Read more about this issue at NBCNews.com
