FREMONT, CA: Distributed Denial of Service, popularly known as (DDoS) has become a serious security concern for the Data Center operators worldwide. A report done by Arbor Networks – the Ninth Annual Worldwide Infrastructure Security report – generated after querying 220 security and network professionals says that Data Center operators are having heightened DDoS attacks that are stronger than ever, reports David Weldon of FierceCIO.

The survey states that DDoS attacks have gone up by 26 percent since 2012, 41 percent of firewalls and IPS systems are reported to have been affected by these attacks,  26 percent of load balancers were hit by these attacks, 36 percent of Data Center operators were affected by these attacks that crossed the available internet bandwidth, 27 percent of these operators reported revenue loss and 81 percent of operators reported operational expenses due to the DDoS attacks.

The DDoS attack size has gone up by 3 times reaching up to a speed of whopping 309Gbps. Secure Sockets Layer (SSL), a protocol for encrypting information over the Internet is also facing more and more attacks, the report says. 33 percent of those surveyed have reported Advanced Persistent Threats (APTs.) Attacks on network infrastructure is up by 6 percent.  As for the Data Centers’ customers, they have every reason to be worried as the report says that they are the most common targets of attack. A significant rise in DDoS attacks has also been reported against the financials and governments.

Focusing at different layers of the network protocol stack, 24 percent of all the attacks were targeted towards the application layer, 82 percent were directed towards web services and as far as Domain Name Server (DNS) is concerned, it saw 77 percent attacks in the year 2013.
