How Do I Start a Career in Network Administration?

The requirements of the network administrator industry for network administrators are basically big and comprehensive. They do not need to be proficient. So, to sum up, a qualified network administrator is best to have solid theoretical knowledge and application skills in six aspects: network operating system, network database, network equipment, network management, network security, and application development. To be handy and easy. ^{[1] The} national professional qualification examination qualification certificate defines the network administrator as the application ability of personnel engaged in computer network operation and maintenance.

Network administrators are too cautious

The whole point of "Mr. Security" is to prevent anything that is bad for his network

Love happens. The line is operated by the contractor, and the cabinets, patch panels, routers, and UPS are installed by the manufacturer. All he is responsible for is to place a dusty mouse ball in his drawer. Use it as a replacement. " His approach to avoiding conflicts was to lock the system so tightly that no one or anything could change the system. Sometimes this means that all users can do is log in and change their own password, and every time they use the password, it may become invalid. Running programs and editing files is too dangerous for users, so users can only face one login interface and one ordinary desktop system. Such administrators have never been attacked by a virus for years, and they will never encounter it again. Not only did he disable the USB slot in the BIOS of each workstation, but the BIOS was also password protected, and even the jack was sealed with glue to prevent tiny data from leaking out through the USB storage device. The mail server is not allowed to install any other attachments; if the network line is changed, the workstation cannot be started; the hardware equipment of the system has been fixed, and the flexibility of the equipment has been lost. If someone tries to open the casing of the machine, a small explosive device will render the machine unusable (and may harm the operator).

Network administrators frequently update the network

Regardless of whether you want him to do so, this type of network administrator will manage application and system upgrades through remote control. Automatically shut down your workstation at the end of each day's work, and you can't stop him from doing so because he puts each workstation on the network into Wake on LAN mode. If you really want to stop him, you must disconnect the network cable from your workstation. When you get off work at 5 pm, your computer is still fully functional, but when you go to work the next morning, you will find that your system has completely changed into another look. You can't find any programs you used yesterday .

Network administrator's work is rigid

Such administrators can often be encountered in the UK's administrative department. If you ask him to do something exceptional, he will answer you: "That's beyond my job duties."

Try to bring a USB storage device to the office while he is on duty and see if it will

What happened! If he puts the storage device in his lunch bag when he didn't notice, he would even have to deal with his default. One day, if he finds that the e-mail sent by a machine is not completely related to work, he will think it is a work accident that should not occur.

Network administrator does not consider consequences

This type of inconsiderate administrator is constantly experimenting with new patches or upgrades.

Most sensible network administrators test a small experimental network before applying the new solution to an existing system. However, such administrators operate directly in the existing system, which often brings unnecessary boredom to users. This is similar to the response of users to administrators who frequently update the network. The difference is that the administrator who frequently updates the network will definitely try to ensure that his product or upgrade behavior is really effective and will not cause any other impact on the network and users.

Network administrator considers network private

As the name suggests, the network is considered private property by such administrators. Anything that might affect the smooth operation of the network will excite him. You might think this is a good thing, but the "private property owner" has done a little too much. He keeps detailed logs to show that the network performance is 100%. But this can be achieved without any network resources allocated to ordinary applications.

System process

We used to appear in large numbers in academia in the past. Usually there is enough redundant space on the network, and some students will use them for their thesis or research work. However, the main function in these redundant spaces is to provide a gaming platform for managers of IT equipment in schools. Most of the network resources are only available to those who log in as "administrators". These people regularly play online battles. In the game, they use various highly imaginative means to make the other party disappear from the network. Today, these people can also play games at home thanks to the availability of cheap, small routers and switches. After a day's work in the computer room, nothing is more relaxing than playing a few hours of gaming in the online world.
