ICSP CS case studies
ICSP CS · Put your knowledge to work in context.
The ICSP CS (ICSP Certified Specialist) is a vendor-neutral, multiple-choice certification aimed at practitioners who need working breadth across information security rather than depth in a single product. It suits security analysts, engineers, administrators and consultants who already handle day-to-day controls and want a credential that maps to recognised security domains: governance and risk, access control, cryptography, network and communications security, architecture and engineering, assessment and testing, operations, software development security, and asset security. The ICSP CS case studies are 5 cases and about 2,683 words.
