With cyber-attacks continuing to grow in sophistication and frequency, both public and private organisations have been forced to change their outlook on cyber-security and re-examine their strategies when it comes to protecting their networks. System breaches are no longer considered unlikely, and the mindset has shifted to cyber-attacks being a matter of ‘when’ rather than ‘if’. With cyber-attacks continuing to grow in sophistication and frequency, both public and private organisations have been forced to change their outlook on cyber-security and re-examine their strategies when it comes to protecting their networks. System breaches are no longer considered unlikely, and the mindset has shifted to cyber-attacks being a matter of ‘when’ rather than ‘if’. Many critical infrastructure installations are controlled by Supervisory Control And Data Acquisition (SCADA) solutions that were never designed to be secure. However, with the correct strategic focus and resources applied, SCADA systems can be secured. Ross Brewer of LogRhythm suggests that a ‘protective monitoring’ approach can be tailored around networks that support high-value cyber-assets.
