Analysis: Counting the cost of a DDoS attack
In the past month, the Information Commissioner’s Office (ICO), the Leveson inquiry website, Visa and Virgin Media have all been hit by distributed denial of service (DDoS) attacks. Much had been made of the motives for such attacks, and the methods that attackers use, but what impact do they have on the victim’s finances?
John Pescatore, analyst at research firm Gartner, told Computing that there were three main costs associated with attacks. “There is the cost of the outage, as it means that a business’s customers cannot reach them through the internet. Then there is the cost of making the attack stop – and, often, a third cost in the form of a potential extortion fee,” he said.
Obviously losses vary, depending on how much revenue is generated directly from a company’s web presence. John Roberts, head of managed services at MSP Redstone, said: “If a betting organisation trades £600m a year – or £2m a day in revenue terms – and 50 per cent of that comes from the web, then they are losing £1m a day.” Any web-dependent organisation within the global 1,000 might incur similar losses, he added.
