The certification
How to earn the CISSP
The CISSP (ISC2) is more than an exam: it also requires experience, an endorsement and an ethics commitment. Here are all the criteria.
2 · Prove your experience
5 years of cumulative, paid work experience in at least 2 of the 8 CBK domains. −1 year with a 4-year degree (or higher) or an ISC2-approved credential → 4 years minimum.
3 · No experience yet? Associate
You may sit the exam before having the experience: if you pass, you become an Associate of ISC2 and have 6 years to earn the required 5 years.
4 · Get endorsed
Within 9 months of passing, an existing ISC2-certified professional attests to your experience. Otherwise ISC2 can act as endorser.
5 · Agree to the code of ethics
Subscribe to and uphold the ISC2 Code of Ethics (4 canons); answer the legal/background questions at registration.
6 · Maintain the certification
120 CPE credits over 3 years (continuing education, ~40/year) plus the Annual Maintenance Fee (AMF). Otherwise it expires.
