"Three-point technology, seven-point management" is a famous saying in the field of network security. Its original intention is that 30% of network security depends on computer system information security equipment and technical support, and 70% depends on the improvement of users' safety management awareness and the update of management mode. Specific to the network version of anti-virus software, three points rely on anti-virus technology, seven points rely on centralized management of the network. Perhaps the above statement is not necessarily accurate, but it can emphasize the importance of centralized network management and network anti-virus system.
