The boom of hybrid cloud, BYOD and private virtual clouds are upon us, and as the use of bandwidth-intensive enterprise applications spiking, many large players are spearheading the adoption of Software Defined Networks (SDN) for flexibility, availability and performance. After all the initial skepticism was put to rest, it is quite clear that SDN is here to stay. But the pressing issue seems to be the protection of its dynamic potentiality from compromise.

http://bit.ly/1tBd6Fd | The Storm Network Stress Tester DDoS crimeware toolkit targets Windows XP (or higher) operating systems, infecting computers with malicious software that turns them into attacker-controlled, obedient zombies. Once infected, malicious actors can manipulate the computers they control remotely, allowing an almost unlimited variety of abuse. Find out more about this DDoS threat in the full Prolexic Storm Network Stress Tester Threat Advisory,

http://bit.ly/1nyT8CX | By exploiting vulnerable DNS servers – or setting up their own – malicious actors can launch powerful DDoS reflection attacks using the new DNS Flooder cybercrime toolkit. The toolkit exploits nuances of the DNS protocol to amplify attacks by a factor of 50 or more, while making the attacker almost entirely anonymous.
