What does an information security management system (ISMS) have to do with critical infrastructure?

The current events surrounding the COVID crisis or the almost daily new news about “hacked” companies show us all how important the secure operation of (critical) infrastructures is for our society and your business success. We take it for granted that the supply of electricity or food is maintained just as much as the operation of hospitals or the production of medical goods. But it is also necessary for the manufacturing industry that production processes experience as few interruptions as possible.
WHAT DOES THIS HAVE TO DO WITH INFORMATION SECURITY MANAGEMENT?
Information Security Management (ISM) makes a significant contribution to the safe (Safety & Security) operation of IACS/OT plants (IACS: Industrial Automation and Control Systems, OT: Operational Technologies). Within the scope of the ISMS, the following protection goals, among others, are addressed with technical and organizational (protection) measures:
- Availability
e.g. precaution against pandemic, protection against cyber attacks (e.g. cyber extortion, economic warfare in cyber space, ransomware) – respectively protection against IT/OT failures - Integrity
prevention of data corruption e.g. customer data, IT/OT system configurations - Confidentiality
e.g. know-how protection, data protection
At this point, allow me to ask: “Have you already had problems with one or the other protection goal in your company?”
In any case, the legislator sees the challenges for society. The NIS-G and supplementary ordinances were enacted to ensure security of supply. Essentially, the goal is to protect our (critical) infrastructure from the effects of cyber attacks – e.g., to prevent a blackout. In order to achieve these goals, the legislator stipulates that the companies concerned must establish protective measures for secure IT/IACS/OT operations and prove their effectiveness via regular audits.
To deal with this task in a structured manner, it makes sense to establish an Information Security Management System (ISMS). There are a large number of best practices and standards for this purpose. The most widely used standard in Europe is ISO/IEC 27001, while the IEC 62443 family of standards has been developed for security in IACS/OT environments. While ISO/IEC 27001 essentially addresses the challenges of IT, IEC 62443 specifically targets the requirements in IACS/OT environments. The standards are comprehensively compatible at management system level and thus offer the possibility of forming an end-to-end security management system.
An essential component or the core process of an ISMS is Information Security Risk Management. This enables structured improvement potentials to be identified in the operation of the IACS/OT infrastructure.
With the Risk Management tool CRISAM® an Austrian solution is available which is already used by more than 50% of the ISO 27001 certified companies in Austria.
