  • BProvide diligent and competent service to principals
  • CAct honorably, honestly, justly, responsibly, and legally
  • DProtect society, the commonwealth, and the infrastructure

Explanation

Working simultaneously for two competing organizations in the same security role creates a conflict of interest that violates the duty of diligent and competent service to principals under the (ISC)2 Code of Ethics.

Common mistakes.

  • A. Canon IV ('Advance and protect the profession') concerns behaviors that reflect on the reputation of the cybersecurity field as a whole, such as discrediting the profession publicly - not conflicts of interest between employers.
  • C. Canon II ('Act honorably, honestly, justly, responsibly, and legally') addresses personal integrity and lawful conduct broadly; while dual employment may touch on honesty, the more specific and directly applicable canon is the duty owed to principals.
  • D. Canon I ('Protect society, the commonwealth, and the infrastructure') pertains to safeguarding the public and critical infrastructure from harm, which is not the primary issue raised by a conflict of interest between two private employers.
