• New ISA84 Technical Report on Security Countermeasures Related to SIS

    The ISA84 standards committee on functional safety has published ISA-TR84.00.09-2013, Security Countermeasures Related to Safety Instrumented Systems (SIS). The new technical report addresses and provides guidance on countermeasures used to reduce the likelihood of a security breach of the SIS that degrades its ability to perform its functions.

    The technical report is part of a series of ISA84 standards and technical reports that address the issue of SIS security. It describes performance criteria to guard against internal and external security threats to the SIS and provides guidance on how to comply with IEC 61511 and ANSI/ISA-84.00.01-2004 with respect to cybersecurity.

    The underlying premise of the document is that the means to implement, operate, and maintain system security should not compromise the performance of the SIS. To this end, SIS installations should be designed and maintained using the foundational requirements found in IEC 61511 and ANSI/ISA-84.00.01-2004, and in the ISA99/IEC 62443 series on cyber security.
