description CISSP Overview
CISSP, short for Certified Information Systems Security Professional, is an ISC2 credential aimed at experienced information security practitioners. Its scope covers eight domains, including asset security, identity and access management, and software development security. The emphasis extends beyond individual technical tools to the decisions involved in designing, implementing and managing security across an organization. That breadth makes it relevant to security architects and managers who need to connect technical controls with business risk.
It is not a certification focused on a single vendor's products, nor does passing an exam alone establish practical expertise. Earning the full credential also involves experience and endorsement requirements. The official exam outline sets out the domains and eligibility framework.
