Cvber chameleon: a changing threat

摘要

Ten years ago the number and sophistication of malware attacks was relatively trivial compared with those experienced today. Even five years ago, a defence strategy with a perimeter defence (a firewall) and a good antivirus (AV) product could reasonably protect endpoints. Details of any attacks would be quickly shared by AV vendors around the world resulting in the creation of patches to prevent malware spreading. Provided an organisation was not patient zero (or more likely one of the first 10,000) - and had the resources to apply patches in a timely fashion - it was unlikely to be severely affected. Today's attacks are much more sophisticated. There is no longer a perimeter to protect because most organisations have transformed (or are in the process of transforming) their services to be fully digital, systems are moving from on-premise to the cloud, including finance systems, and client interactions are increasingly delivered via digital applications.
