The first guarantee of data security is "the security of the network system." Because the network system is particularly important in the database, it is the first barrier for the database. If the security of the network system is broken, the security of the database will be in danger, and the data in the database will be destroyed and leaked.

Network system, full name network operating system, this term is used to represent two quite different concepts: a special operating system running on routers, network switches, and firewalls; (Recommended learning: web Front-end video tutorial)
An operating system for computer networks that allows multiple computers in the network to access shared files and printers, allowing sharing of data, users, groups, security, applications and other networks Function. Usually deployed on a local area network or private network. Since general-purpose operating systems now include many features, this statement is a thing of the past.
At present, there are mainly the following types of network operating systems in local area networks:
Windows type
Microsoft's Windows system is not only It has an absolute advantage in personal operating systems, and it is also very powerful in network operating systems. This type of operating system configuration is the most common in the entire LAN configuration. However, because it has higher hardware requirements for servers and is not very stable, Microsoft's network operating system is generally only used in mid- to low-end servers and high-end servers. Usually non-Windows operating systems such as UNIX, LINUX or Solairs are used.
NetWare class
Although the NETWARE operating system is far less popular than it was in the early years, and has long lost its dominance in the local area network, the NetWare operating system is still The requirements for network hardware are low (the workstation only needs to be a 286 machine) and it is favored by some small and medium-sized enterprises with relatively backward equipment, especially schools.
Unix system
The currently commonly used UNIX system versions mainly include: Unix SUR4.0, HP-UX 11.0, SUN's Solaris8.0, etc. It supports network file system services and provides data and other applications. It is powerful and launched by AT&T and SCO.
Linux
This is a new type of network operating system. Its biggest feature is that its source code is open and many applications can be obtained for free. There are also Chinese versions of Linux, such as REDHAT (Red Hat), Red Flag Linux, etc.
