The invention discloses a method and a
system for protecting hard disk information of a notebook computer, and relates to the technical field of information protection. During operation of the
system, data of various operations in the
system are monitored and recorded, the acquired data are formatted and standardized,
encryption keys are stored and managed, and all
encryption and decryption operations are executed; a physical isolation environment is provided to protect a secret key from external access, a multi-factor identity
verification technology is used to verify the identity of an access user, only the user passing
verification is allowed to access hard disk data, the
access control security of a system is improved, real-time
encryption and decryption operation of data is performed according to the secret key provided by an HSM, and the security of the system is improved. The security of data in the read-write process is ensured, complete encryption in the data storage and transmission process is realized, the
confidentiality and integrity of the data are ensured, system operation is monitored, all logs about hard disk access and security events are recorded, and detection and response of the security events are implemented.
