The short version of the (ISC) 2 code of ethics contains four canons:
Protect society, the commonwealth, and the infrastructure.
Act honorably, honestly, justly, responsibly, and legally.
Provide diligent and competent service to principals.
Advance and protect the profession.
When you earn the CISSP certification, you are obligated to do these things. In fact, you are required to take on a new responsibility as a protector of the organizations that you are directly or indirectly involved with.
Tip The best approach to complying with the (ISC) 2 code of ethics is to never partake in any activity that will provide even the appearance of an ethics violation. Making questionable moves puts your certification at risk, and it may also convey to others that such activity is acceptable. Remember to lead by example!
