Multi-layered security pitfalls in blocking DoS attacks

Prolexic Technologies : 15 November, 2013  (Technical Article)
Prolexic releases a white paper explaining the pitfalls to businesses of deploying multi-layered network security as a means of blocking DoS attacks
Multi-layered security pitfalls in blocking DoS attacks

Prolexic has published a new white paper that alerts businesses of the pitfalls of a multi-layered network security approach for blocking denial of service attacks. The paper can be downloaded from the Prolexic web-site.

“Experience has shown that the more layers of security, appliances and providers involved in mitigation, the longer it takes to block a DDoS attack,” said Stuart Scholly, president of Prolexic. "There are too many possible weak links in a multi-layered approach that increase the risk of website downtime rather than reduce it. That is why Prolexic recommends a ‘single, strongest defense’ strategy to block DDoS attacks.”

The free Prolexic white paper, Why a Multi-Layered Security Strategy is Not Ideal for DDoS Mitigation, examines the common types of cyber security measures and the DDoS attack variants that can easily penetrate them. Prolexic states a strong case for switching from the industry norm to a single, strongest DDoS defense as the best way to achieve the fastest mitigation, block DDoS attacks, and minimize downtime.

The white paper will help executive-level and IT management gain a better understanding of:

* The broad impact of lengthy DDoS-driven site outages
* How complex DDoS variants can topple firewalls, routers, on-premise appliances, self-hosted DNS servers, and other traditional cyber security measures
* Why multiple layers of security devices and vendors can actually delay DDoS mitigation

The Prolexic white paper also includes a case study that provides a real-world example of a financial firm, whose multi-layered cyber security defense failed to block a complex DDoS attack, resulting in serious financial losses due to lengthy downtime. In contrast, a second case study illustrates the benefits of having a specialist DDoS mitigation service in place as a first responder to a DDoS attack.
