Viruses and security breaches are just a running risk to most businesses, causing some bad days for the IT team. Can they cause catastrophic damage?
It is true that there is a level of virus damage that is fairly ubiquitous: over 50% of businesses suffered some damage according to the DTI 2004 survey. However the survey also showed that 1% of businesses that suffered a security incident experienced a very major disruption of between a week and a month, and a further 1% experienced major disruption of over a month. The most severe security incidents cost over £500,000.
