1.？ physical features
Network physical security is the premise of the whole network system security. Active or passive emission information (number) such as electromagnetic sound and light generated by processing confidential information; If the classified equipment and secret carrier formed after copying, copying and printing are not properly protected or handled, the classified information may be restored by foreign spy intelligence agencies through special tools.
2.？ Hardware aspect
Network hardware security usually includes two aspects: hardware equipment and protection intensity configuration. Generally speaking, by setting traps in hardware devices, we can monitor other people's networks in real time, steal secrets and destroy networks.
3.？ Software aspect
Software is the "brain" and "soul" of computers and computer networks. Using software vulnerabilities to attack and steal secrets is one of the most commonly used means for hackers.
4.？ The human aspect
The awareness of network information security and confidentiality of unit personnel also affects the network security of enterprises. The insider's intentional or unintentional behavior will cause leaks.
5.？ External attack
Network security is closely related to national security, and the purpose, subject, methods and means of network attacks have also changed accordingly. The corresponding network information security solutions of enterprises should also be handled accordingly.
Secondly, we must rely on professional network information security management experts.
There are mature management systems such as domain shield, safety enterprise spirit and Zhongke safety enterprise. It uses the idea of system management, makes full use of technical means such as operation audit, authority control and document encryption, and comprehensively solves intranet security problems such as information security, behavior management and system operation and maintenance.
It can realize six information security management functions.
Including centralized management, security management, security audit, outreach control, security strategy, key management, in-depth behavior analysis and so on.
Through online behavior review, chat record and screen control, we can defend beforehand and stifle risks in the cradle; By restricting the use of USB flash drive and prohibiting software, you can control the office computer in the process and make it healthier; By recording the computer operation in detail, we can trace the responsibility afterwards.
To sum up, the solution of enterprise network information security is a complex subject, which needs to be considered and studied from many aspects.
