Critical infrastructure organisations need a cyber-resilience strategy

22/01/2013

Critical infrastructure companies have long been a target of cyberattackers, especially advanced persistent threats (APTs) with the objective of stealing information or compromising information systems. In addition to the cyberattacks, critical infrastructure companies can be affected by weather changes and other unforeseen circumstances, which can lead to severe disruption on their operations. Experts warn that having a cyber-resilience strategy in place is of paramount importance to critical infrastructure companies for ensuring operational continuity.
 
Alan Calder, CEO of cybersecurity experts IT Governance, says, “Cyber-resilience means that an organisation's systems and processes are resilient against outside attack or natural disaster. This is best achieved by integrating an organisation’s information security management system (ISMS) with its business continuity management system (BCMS). Severe weather leading to power cuts and traffic disruptions can affect all organisations. It can be particularly damaging for critical infrastructure companies, on which all of us are reliant. Unless they have a well-managed business continuity system to ensure continuity of operations the situation can easily get out of control.”
 
Calder adds, “The importance of mitigating the disruption to information technology services has been at the heart of disaster recovery and business continuity plans for many years. Ensuring that an organisation’s IT systems and processes are resilient against natural disaster, or outside attack, is a key principle underlining the ISO22301 and ISO27001 standards.”
 
Organisations can integrate these two systems by using the ISO/IEC 27031 Guidelines for ICT Readiness for Business Continuity. ISO27031 provides a bridge between general business continuity management and information technology, tying together ISO27001 and ISO22301 and enabling information and communications technology (ICT) business continuity preparedness.
 
Critical infrastructure companies can obtain internal knowledge and skills of implementing and integrating both systems by sending staff on specialist training courses. Both ISO27001 Certified ISMS training courses and ISO22301 Certified BCMS training courses are available from IT Governance. They can be booked online at www.itgovernance.co.uk/training.aspx.
