What does the term "information" include in a security context?

The term "information" in a security context encompasses a wide range of data types that organizations handle. This includes not only proprietary data, which is sensitive and critical to the business's operations and competitive advantage, but it also covers other forms of information that could be subject to security measures. Proprietary data typically includes trade secrets, intellectual property, confidential business plans, client and customer information, and other sensitive data that, if compromised, could harm the organization.

Considering various types of proprietary data as part of "information" is essential for effective risk assessment and security planning. It allows organizations to identify and classify data based on importance, develop relevant security controls, and ensure compliance with legal and regulatory requirements.

Other options, while important in their own contexts, do not capture the comprehensive nature of "information" as it pertains to security. Public domain data is generally not sensitive and does not require the same level of protection. General knowledge available to all employees often does not reflect the proprietary nature of information that warrants a security focus. Classified information, while indeed a critical category, is just one subset of the larger spectrum of data that may require protection depending on its context and sensitivity.
