Information security of digital automation systems

While the phrase "information security attack" is never good news, it is paricularly ominous in the context of production environments.

Broadly speaking, attacks against industrial automation systems can be divided into two groups: unintentional and intentional. In an unintentional attack, the industrial automation system is just collateral damage. Such an attack arises when malware intended for ordinary ICT systems enters a production environment. Intentional threats are always targeted attacks against particular operators - the attacks designed to disrupt Ukraine’s power supply in December 2015 are a good example of this.
