Marrying IEC62443 Cybersecurity Levels (SL) with IEC61508 SIL
The standard IEC 62443: Security for industrial automation and control systems (IACS) proposes the assignment of security levels 1-4 to IACS zone provisions.
The temptation is to see these as comparable to the four Safety Integrity Levels of IEC 61508, but this would be a mistake; there is no equivalence. This paper will explore the relationship between SL and SIL and show how they may be related through an appropriate risk calibration for a given enterprise.
