The world has become reliant on computers and digital personal and business information. This has exposed individuals, organizations and entire countries to significant threats, and these must be managed as new forms of cyber-terrorism, cyber-crime and cyber-fraud that are emerging. With products and services increasingly provided, sourced and accessed online, the security of sensitive personal and corporate data and systems is vital if cyber-attacks are not to damage operations and reputations. Theft of digital information has become the most commonly reported fraud, surpassing physical theft, and recent research indicates that the relative insecurity of small and medium-sized enterprises is making them a growing focus for cyber-attacks.
