The continuous development of network information technology and the continuous improvement of hardware configuration will inevitably mean that old equipment will be eliminated, but what should be done with the storage media of those classified computers that are to be eliminated?

Solution: 1.Before the use of office automation equipment such as computers involving secrets is eliminated, technical equipment that meets national confidentiality standards shall be used to remove information related to secrets or sensitive internal information, so as to ensure that it cannot be restored.

2.Send the secret-related computers and other secret-related office automation equipment that are about to be phased out to the destruction agency set up by the department for the administration and management of secret-guarding or the designated underwriting unit for destruction.

It is difficult to completely erase the information by simply deleting or formatting the information from the computer or removable storage media, but it can still be recovered by relevant technical means.

Therefore, it requires the use of specialized technology for destruction. The destruction of professional secret-related carriers refers to the use of special technical means to completely eliminate confidential information stored in confidential computers and confidential mobile storage media, so that the information content cannot be recovered by any technical means. Obsolete and scrapped classified computers and classified mobile storage media are still secret carriers and cannot be transferred, donated or used as scrap at will.
