Everyone said that using computer is software, the importance of software is self-evident. However, as the basis of the computer, hardware is the most basic element to ensure the reliable operation of the software. In fact, software and hardware are mutually dependent and interdependent. For example, in many cases, for security reasons, we often want to make the necessary restrictions on the use of hardware. The easiest way to handle this is to use a variety of security software to lock the relevant hardware. This article introduces several software related to hardware security. Below, the system home Xiaobian introduces you how to implement ADSL Modem, camera, keyboard and mouse, printer, USB port, Bluetooth, CD-ROM, IEEE1394, infrared port. , technology such as network card locks. I hope that I can start the role of throwing bricks and lead the jade, and guide everyone to discover more security software to better realize the safe use of hardware. For the ADSL cat plus "dark lock", neighbor Wang Ayi recently bought a new computer, installed broadband, wonderful network world, brought a lot of fun to Wang Ayi's family life. However, the troubles followed, and the children of Wang Ayi’s family fell in love with online games, causing the academic performance to decline. This makes Wang Ayi very worried, it seems necessary to take control measures to prevent children from indulging in the network.

At the same time, when you want to be able to lock the mouse and keyboard at any time to lock the mouse and keyboard, then at any time enter the unlocking whisper to restore the vibrancy of the mouse and keyboard. All kinds of port lock company CEOs handed over some important documents to the secretary Xiaohua, telling him to keep it safe and not to let unrelated people contact. Xiaohua naturally does not dare to neglect, but can not always hold the computer, it seems that they have to think about other strategies. After some thinking, Xiaohua believes that as long as the possible leaks of the computer are completely closed, the data can naturally sit back and relax. With the software of Port Locker, Xiaohua finally found a good solution to the problem. Port Locker can completely block the connection between the USB port, IEEE 1394 port, network card port, optical drive port, printer port, infrared port and other computers connected to the outside world, just like locking all the windows and doors of the room.
