The first phase in the IACS Cybersecurity Lifecycle (defined in ISA 62443-1-1) is to identify and document IACS assets and perform a cybersecurity vulnerability and risk assessment in order to identify and understand the high-risk vulnerabilities that require mitigation. Per ISA 62443-2-1, these assessments need to be performed on both new (i.e. greenfield) and existing (i.e. brownfield) applications. Part of the assessment process involves developing a zone and conduit model of the system, identifying security level targets, and documenting the cybersecurity requirements into a cybersecurity requirements specification (CRS).
This course will provide students with the information and skills to assess the cybersecurity of a new or existing IACS and to develop a CRS that can be used to document the cybersecurity requirements for a project.
Length: 3 days
CEU Credits: 2.1
This course is part of the ISA Cybersecurity Certificate Program.
You will be able to:
◾Identify and document the scope of the IACS under assessment
◾Specify, gather, or generate the cybersecurity information required to perform the assessment
◾Identify or discover cybersecurity vulnerabilities inherent in the IACS’ products or system design
◾Organize and facilitate a cybersecurity risk assessment for an IACS
◾Identify and evaluate realistic threat scenarios
◾Identify gaps in existing policies, procedures, and standards
◾Establish and document security zones and conduits
◾Develop a cybersecurity requirements specification (CRS)
