How to Obtain CISSP Certification

Prerequisites

To be eligible for the CISSP certification, candidates must have a minimum of five years of cumulative, paid work experience in at least two of the eight domains of the CISSP Common Body of Knowledge (CBK). A four-year college degree or an approved credential from the (ISC)² list can substitute for one year of experience.

Examination

The CISSP exam is a rigorous test of an individual’s knowledge and skills across the eight domains. It consists of 100-150 questions and must be completed within three hours. The exam is adaptive, meaning the difficulty of questions varies based on the candidate’s responses.

Endorsement

After passing the exam, candidates must be endorsed by another (ISC)² certified professional, verifying their professional experience and good standing in the cybersecurity community.

Continuing Education

CISSP certification requires ongoing professional development. Certified individuals must earn Continuing Professional Education (CPE) credits to maintain their certification. This ensures that CISSPs stay current with evolving security trends and technologies.
