When you pass the exam, you still need to attest to the CISSP code of ethics and have an existing CISSP complete a endorsement form for you.
When you receive notice of your passing grade, a blank endorsement form will be sent with it. The endorsement form must be completed by someone who can attest to your professional experience and who is an active CISSP in good standing. If you don't know anyone who is CISSP certified, ISC2 allows endorsements from other professionals who are certified, licensed, or commissioned, and an officer of the corporation where you are employed. You can review complete information on the endorsement form at the ISC2 website.
