The national standard GB/T21028-2007 "Information Security Technology Server Security Technical Requirements" jointly released by the Standardization Administration of China and the General Administration of Quality Supervision, Inspection and Quarantine began to be officially implemented on December 1. The information security national standard system, led by Inspur and participated in by domestic server manufacturers such as Lenovo and Dawning, is China's first server security standard. It is understood that according to the security level of the server procurement party, different server security standards will be implemented. Level three is the dividing line between mandatory and non-mandatory. Due to the restrictions of the export policies of Europe and the United States, some products of international manufacturers in the current Chinese market do not meet the requirements of this level, such as IBM, HP servers using UNIX operating systems and Microsoft's Windows server operating systems.
