Analysis of Five Security Strategies for Windows XP Operating System

        With the popularity of Windows XP on personal computers, more and more people are beginning to work with Windows XP, even though Windows XP has superior stability and reliable security. However, the vulnerabilities discovered one after another have caused Windows XP to be threatened by attacks. It is necessary to fix the patches released by Microsoft in time, but in addition, what can our users do for the security of our own computers? I have a feeling of reading online, summed up the five points of network security knowledge, DIY our own security.

First, close the unneeded service

The service components used by ordinary users are limited, and hackers often exploit the vulnerability of some service programs. computer. In addition, in the case of relatively tight system resources, additional services can lead to more system resources and system instability. Therefore, ordinary users should try to stop those services that are not needed. The operation is as follows: In the "Start" of Windows XP, find "My Computer", right-click to open the "Administration" item, and then click the "Services" sub-directory "Services". Information about "Services" will appear on the right side of the "Window" and you can close or open the service as prompted.

Second, important information needs to be encrypted

Important information encryption is too important! The information we store in the computer will leak out from a variety of vulnerabilities, including direct attacks on computers, trojans, peeks when insiders use the author to leave temporarily, and so on. Therefore, the simplest one to deal with the above threats is encryption. Perfect encryption can make others can't open the file, and can't see the file, which achieves the purpose of confidentiality. Windows XP provides encryption of folders and files when using the NTFS format. The operation is: find the folder or file that needs to be encrypted and right click to bring up the property page.

3. Lock your computer if necessary.

If you are in a hurry to use your computer and need to leave the computer for a short time, many people know that you can pass Use the CTRL+ALT+DEL key combination or screen saver to achieve the purpose of locking the screen. However, there is some complexity here. The following way allows you to lock the machine by simply creating a shortcut and tapping it. Refer to the following process: first right click on the Windows XP desktop, then select "New" /"Shortcut" in the right-click menu, then follow the on-screen prompts, enter "rundll32.exe user32." in the command line text box. The dll, LockWorkStation" command character, and then enter the specific name of the corresponding shortcut in the subsequent wizard window, you can directly name the shortcut "lock the computer".

4. Windows XP comes with a firewall function

Windows XP comes with the "Internet Connection Firewall" function. With this function, Windows XP can access the system. All of the information is filtered dynamically to minimize hackers on the network from accessing their network. The operation process is as follows: Click the "Settings" /"Network Connections" menu item in the Start menu, then select the corresponding connection from the pop-up window, right-click the connection, select "Properties", and then pop up the Dialing Properties window. Then click the "Advanced" tab, select the "Internet Connection Firewall" option, and then click the corresponding "Settings" button of the firewall to set up the firewall according to your requirements, so that the firewall can work more efficiently, generally Do not tick all options.

V. Screen Protector Programs Available at Any Time

Generally, the screen saver will be started only when the computer is not operated for a preset time. I want to start the screen saver at any time. The process is as follows: In the Windows XP Start menu, click "Start" /"Search" /"Files or Folders" and enter "In the text box of the corresponding file name" *.scr" characters. Finally, all the files searched for are mostly screen saver files. Just create a shortcut to the screen saver on the desktop, naturally letting you see your cute screensaver anytime, anywhere.
