SYS342 is an intensive, 40-hour, instructor-led course that includes eight small-group exercises in which attendees apply principles learned in the class to a representative case study weapon system. This course provides students assigned as Security Control Assessors (SCA/SCAR) and Information System Security Managers (ISSM), weapon system engineers, developmental and operational testers and mission defense team (MDT)members with the knowledge required to conduct architectural analyses to identify cybersecurity threats to weapon system designs and to assess and mitigate the cybersecurity vulnerabilities associated with those designs. The focus of SYS342 is on weapon systems in the sustainment phase of the system lifecycle. Course Objectives: (1) Know core requirements of cyber risk assessments and authorization packages (2) Understand how to assess the cybersecurity mission risk to a weapon system (3) Understand how to build an acceptable authorization package.
