Extensive media coverage of the array of Dedicated Denial of Service (DDoS) attacks that have been directed towards company websites opposed to Wikileaks has invariably raised concerns about internet security.
And with cloud computing- already perceived by some as being inherently less secure than traditional infrastructure- forecast for exponential growth; doubts and concerns about its security have been voiced.
Professor John Walker member of ISACA Security Advisory Group and CTO of Secure-Bastion, however, suggests that the Wikileaks cyber war’s recent DDoS attacks have in fact demonstrated it to be more robust than the alternatives:
“With the backdrop of common perception that 'anything' Cloud based is insecure, let us consider the inference of the recent successful Denial of Service attacks associated with the WikiLeaks events. Whilst some corporate brands fell under the logical weight imposed by Cyber Attacks, some Cloud based sites successfully sustained their operations during such adverse conditions. Does this not beg the question why this could be? Does this not suggest that some of the better Cloud providers have higher capacity to deal with sustained adverse conditions? Could this suggest that they may not be as insecure as perception would have us believe?”
So what exactly is DDOS? Noa Bar Yosef, Senior Security Strategist at Imperva explains:
“A DDoS, or Distributed Denial of Service attack. A coordinated, massively increased number of participants target a specific website, flooding it with traffic so that the server becomes overloaded. As the site attempts to process the large volume of malicious traffic it denies access from legitimate users and often crashes altogether.”
