With the cyber threat shifting its focus to sabotage rather than data theft, many of the defences deployed by public sector organisations will have to be adapted for the new world.
Information security policies are commonly guided by the CIA triad of confidentiality, integrity and availability. Many of the big security stories in the media relate to confidentiality, where data theft, for example, affects both individuals (eg. personal banking data) but also has a huge economic impact as a result of industrial espionage.
Integrity, or rather its loss, is most evident in the hijacking of websites by “hacktivists” seeking to deface content or replace it with political messages, but can also be associated with data, such as environmental monitoring, stock market trading or consumer price indices.
