Confidentiality is the security objective that best ensures that information is protected against unauthorized disclosure. Confidentiality means that only authorized parties can access or view sensitive or classified information. Integrity means that information is accurate and consistent and has not been tampered with or modified by unauthorized parties. Authenticity means that information is genuine and trustworthy and has not been forged or misrepresented by unauthorized parties. Nonrepudiation means that information can be verified and proven to be sent or received by a specific party without any possibility of denial.

Senior management seeks to understand the business justification for investing in security. This can best be accomplished by tying security to key business objectives. Senior management will not be as interested in technical risks or examples of successful attacks if they are not tied to the impact on business environment and objectives. Industry best practices are important to senior management but, again, senior management will give them the right level of importance when they are presented in terms of key business objectives.
