What is the ISC-squared Code of Ethics and what are its canons?

The ISC-squared Code of Ethics has a preamble and four mandatory canons that all CISSP holders must follow. First, protect society, the common good, necessary public trust and confidence, and the infrastructure. Second, act honorably, honestly, justly, responsibly, and legally. Third, provide diligent and competent service to principals. Fourth, advance and protect the profession. These canons are listed in order of priority, so protecting society takes precedence over loyalty to an employer.
