Windows XP Security Policy (1)

1. Block Unneeded Service Components Although the more service components are installed, the more service functions users can enjoy. However, the service components that users usually use are still limited, and those components that are rarely used not only take up a lot of system resources, but also cause system instability. It also provides multiple ways for hackers to remotely invade. Therefore, we should try to shield those service components that are not needed. The specific operation method is as follows: first find the "Services and Applications" icon in the Control Panel, and then open the "Services" dialog box, select the program to be masked in the dialog box, and click the right mouse button to pop up the shortcut. Select the "Properties" /"Stop" command in the menu, and set the "Startup Type" to "Manual" or "Disabled" so that the specified service components can be blocked. 2, the use of power protection function When using a computer to process files, the most worrying thing is that the computer suddenly loses power, because this sudden power failure will not only make their hard work results instantly disappear, but also seriously damage the computer. In order to prevent accidental power failure under various conditions and to ensure the safe and normal operation of the computer, we should enable the function of asking or directly sleeping when the power button is pressed in the power management. If you want to enable the power protection function, you can use the mouse to click "My Computer" /"Control Panel" /"Power Options" on the Windows XP desktop, select the "Advanced" tab in the pop-up settings box, Under the corresponding tab page, find the "When the computer power button is pressed" setting item, and then select the "Hibernate" or "Ask me what to do" option in the settings box. If you select the "Shutdown" option, it is equivalent to no power supply. Protective function. 3. Encrypt important information To prevent others from using their own computers to peek at the file information stored in the computer, Windows XP specifically provides us with "file and folder encryption" function, which is used by ordinary users. We can encrypt important information stored on the computer so that other users cannot access the contents of the file or folder without a password. When encrypting a file, we first open the Windows XP Explorer, then find the file or folder that needs to be encrypted in the Explorer window, then right-click on the selected file or folder and pop it up. Select the "Properties" command in the shortcut menu, then Windows XP will pop up the file encryption dialog box, click the "General" tab in the dialog box, and then select "Advanced" /"Encrypt content to protect data". 4, lock your computer If you need to leave the computer for a short time in the process of using the computer, many people worry that their computer will be occupied by others, often take the first to shut down, then leave, then come back and then boot Handling, but this frequent switching of the machine is not good for the computer. So, is there any way we can do it without shutting down and preventing others from using our own computer? Of course, there are ways to quickly lock the keyboard and display by double-clicking the desktop shortcut without using the CTRL+ALT+DEL key combination or screen saver. When locking your computer, you can follow the steps below: right-click on the Windows XP desktop, then select "New" /"Shortcut" in the context menu, then follow the on-screen instructions in the command Enter the "rundll32.exe user32.dll,LockWorkStation" command character in the text box of the line, and then enter the specific name of the corresponding shortcut in the subsequent wizard window. Here, for the convenience of calling later, you can directly take the shortcut for the shortcut. It is ok to call "lock the computer". In the future, you can achieve the purpose of locking by simply double-clicking "Lock Computer" on the desktop. 5, the use of "connected firewall" function In the network era, the virus's mode of transmission, speed of transmission and destructive power has changed dramatically, and hacking is also operating worldwide. In order to prevent random invasion of viruses and hackers, many users have installed firewalls on their own computers. Windows XP has added a free "Internet Connection Firewall" feature. With this feature, Windows XP can dynamically filter all information coming in and out of the system, allowing the system to agree to access people and data into

Your own internal network, while not allowing users and data to be blocked, to prevent hackers on the network from accessing their network to prevent them from changing, moving or even deleting important information on the network. When using the "Connect to Firewall" function, you can click the "Settings" /"Network Connections" menu item in the Start menu, then select the dial-up connection you need to access the Internet from the pop-up window, then right-click the connection Icon, and select the "Properties" command, then click the "Advanced" tab in the dialing properties window that pops up, select the "Internet Connection Firewall" option in the corresponding tab page, and then click the corresponding "Settings" button of the firewall. To set up a firewall according to your own requirements, so that the firewall can work more efficiently. 6. Use the screen saver program at any time. When you see the word “screen saver”, you will naturally think of the screen saver in the computer. It mainly uses the different methods to display the specified picture in turn to achieve the purpose of screen protection. But the system will only start the screen saver when the computer is not operated for a preset time. What if we want to start the screen saver in any given time? We can do this by following the steps below: In the Windows XP Start menu, click "Start" /"Search" /"Files or Folders", then in the pop-up search dialog, click "All Files and Type "type" and enter the "*.scr" character in the text box of the corresponding file name. In the search range drop-down list, select "Native Disk (C:)" or the drive where the system file is stored on the computer. Finally, Click the "Search" button. Then in the list of screen savers found, select the desired screen saver, and then create a shortcut for the screen saver on the desktop. When you start the screen saver, double-click the screen saver shortcut on the desktop. 7. Assigning administrative rights to yourself Many programs installed in the Windows XP operating system require users to have certain administrative privileges in order to allow users to use the program. Therefore, in order to be able to use the program, we sometimes need to temporarily allocate an access program for ourselves. Administrative rights. When assigning administrative rights, we can log in to the Windows XP system as a normal user, then right-click the program installation file, and hold down the Shift key on the keyboard, and click "Run mode" from the shortcut menu that appears. ", finally enter the user name and password with the appropriate administrative rights in the pop-up window. 8, the elimination of system suspended animation in the operation of Windows XP applications, due to improper operation or the system itself, resulting in the operation of the program has not responded for a long time, many people think that the computer is definitely a crash, so many people choose Shut down directly or use Ctrl+Alt+Delete to restart your computer. In fact, in Windows XP, some programs that are not working properly will cause the system taskbar to die. This phenomenon is mainly caused by the incompatibility between the currently executed program and the system. When this happens, we can find the executable file of the program, then click the right mouse button, select the "Compatibility" tab in the pop-up dialog box, and then select the corresponding running environment under "Compatibility Mode".
