IEC/ISA 62443 Cybersecurity Bootcamp Day 1 Part 2

When one asset has multiple vulnerabilities then multiple threats and risks also will be there so that multiple SL-T also will be there. Can Multiple SL-T allowed for single assets ?

Hi @sayoojmpremji, It does not work this way, The highest is chose for the device, but against each FR (1 to 7) you can have different levels of SL-T as well.

​@shivkataria Is it same criteria for zones too? I mean a zone will have different assets with different SL-T. So the highest SL-T will become the zone's SL-T ?
