The greatest benefit of information asset classification is providing a basis for imple-menting a need-to-know policy. Information asset classification is a process of catego-rizing information based on its level of sensitivity and importance, and applying appro-priate security controls based on the level of risk associated with that information1. A need-to-know policy is a principle that states that access to information should be granted only to those individuals who require it to perform their official duties or tasks2. The purpose of a need-to-know policy is to limit the exposure of sensitive information to unauthorized or unnecessary parties, and to reduce the risk of data breaches, leaks, or misuse. Information asset classification provides a basis for implementing a need-to-know policy by:

•Defining the value and protection requirements of different types of information

•Labeling the information with the appropriate classification level, such as public, internal, confidential, secret, or top secret

•Establishing the roles and responsibilities of information owners, custodians, and users

•Enforcing access controls and encryption for the information

•Documenting the security policies and procedures for the information

By providing a basis for implementing a need-to-know policy, information asset classi-fication can help organizations to protect their sensitive information, comply with rele-vant laws and regulations, and achieve their business objectives. The other options are not the greatest benefits of information asset classification. Helping to determine the recovery point objective (RPO) is not a benefit, but rather a consequence of applying security controls based on the classification level. RPO is the acceptable amount of data loss in case of a disruption3. Supporting segregation of duties is not a benefit, but rather a prerequisite for implementing a need-to-know policy. Segregation of duties is a principle that states that no single individual should have control over two or more phases of a business process or transaction that are susceptible to errors or fraud4. De-fining resource ownership is not a benefit, but rather a component of information asset classification. Resource ownership is the assignment of accountability and authority for an information asset to an individual or a group5.
