Cyber-security threats will have an impact on every business, whether they are an organisation that has carried out a full digital transformation program or they are just a small business with online banking. The threats are varied and adaptable. They range from high volume, opportunistic attacks where technical expertise is bought, not learned, such as DDoS attacks to highly sophisticated threats involving bespoke malware created to compromise specific targets.
The idea of cyber-crime being carried out by script kiddies in hoodies has been replaced by criminal groups attacking financial institutions and state sponsored cyber-attacks with the potential to influence elections. The past year has seen cyber-attacks on a scale and boldness we have not seen before. These include the largest recorded cyber heist, the largest DDoS attack and the biggest data breach ever being revealed. And the attacks on the Democratic National Party, Ukrainian energy infrastructure, the NHS and Bangladesh Bank demonstrate that no organisation is safe.
The threat is real and it isn’t just an IT problem causing minor disruption. The financial impact is vast. A study conducted by Oxford Economics found that companies’ share prices fall by an average of 1.8% on a permanent basis following a severe data breach. In August 2017, the Government announced that British organisations could face fines of up to £17m, or 4% of global turnover if they fail to take measures to prevent cyber-attacks that could result in major disruption to services such as transport, health or electricity networks. This means a typical FTSE 100 firm is worse off by an average of £120m after a breach, according to the study. It looked at 315 breach events with a focus on 65 “severe” and “catastrophic” breaches occurring since 2013 across seven global stock exchanges.
The analysis showed that investors have lost at least £42bn due to severe public domain cyber-security incidents since 2013.
