You cannot protect what you do not know you have, and you cannot afford to protect everything equally. Asset identification and classification solve both problems. Identification builds an inventory of information and of the assets that store, process or transmit it. Classification assigns each a level of sensitivity or criticality so that protection is proportional to value. Together they form the foundation of Domain 2, Asset Security, and feed into risk management, access control and incident response.
