security word, are critical to any operating system. Only the security of the system is guaranteed to allow the system to operate unimpeded. So in the xp system, how can we do the security protection of the system that everyone is highly respected? Let's study it together.
1. Conventional security protection
The so-called regular security protection is the same as the Windows 98 installation of anti-virus software, upgrade system, prohibit Ping three security methods. It should be emphasized that Windows XP and its predecessor, Windows 2000, have numerous loopholes. The upgrade of the system cannot be as sloppy as Windows98. In addition to installing Microsoft's vulnerability patch for shockwave, it is recommended to upgrade WindowsXP to the latest ServicePack1 (it will be upgraded after upgrade). Resource possession, but security and stability have improved).
2. Disable remote assistance, block idle ports
On Windows XP, there is a function called Remote Assistance, which allows users to send remote assistance invitations to friends on MSN when they have difficulty using the computer. Solve the problem yourself.
And this remote assistance function is exactly the representation of the RPC (RemoteProcedureCall) service that the Blaster virus is attacking on Windows XP. Users are advised not to use this feature, and should also install the RPC vulnerability tool and shockwave immunization program provided by Microsoft before use. The method for disabling remote assistance is to open the System Properties dialog box (right-click on My Computer, Properties) and remove the remote item from the front of the remote assistance invitation.
The port can be restricted using the TCP/IP filtering service that comes with the system. The method is as follows: Right click on the network connection, select Properties, open the Network Connection Properties dialog box, select the Internet Protocol (TCP/IP) in the General tab and click the [Properties] button below to configure the Internet Protocol (TCP). /IP) Properties window, click the [Advanced] button below, select the option item in the pop-up advanced TCP/IP settings window, click the [Properties] button below, and finally pop up the TCP/IP filtering window, through the window Only allow radio buttons, add ports allowed by network protocols such as TCP, UDP, and IP. If you do not provide various services, you can block all ports. This is the best form of security.
3. Disabling Terminal Services Remote Control
Terminal Services is a form of service left over by Windows XP on Windows 2000 (Windows 2000 uses this service for remote server hosting). Users can use the terminal to achieve remote control. Terminal services and remote assistance are different. Although they all implement remote control, terminal services pay more attention to the user's login management rights. Each connection requires a specific login ID of the current system and is isolated from each other. Terminal services are provided. Independent of the invitation of the current computer user, you can log in to the remote computer independently and freely.
Under Windows XP, Terminal Services is opened by default (Windows 2000 system needs to install the corresponding components before you can open and use Terminal Services). That is, if someone knows a user login ID on your computer, and Knowing the IP of your computer, it gives you complete control over your computer.
The method of turning off Terminal Services in Windows XP system is as follows: Right-click to select my computer, properties, select remote items, and remove the user to remotely connect to the front of this computer.
4. Turn off the Messenger service
The Messenger service is a communication component that Microsoft integrates into Windows XP system. It is also opened by default. When using it to send information, as long as you know the IP of the other party, and then enter the text, the corresponding text message window will pop up on the other party's desktop, and will be accepted if the Messenger service is not closed.
Many users don't know how to turn it off, but they are harassed by information. In fact, the method is very simple, enter the control panel, select the management tool, start the service item inside, then right click on the Messenger item and select Stop.
5. Prevent IPC default sharing
WindowsXP allows any user to get all account and share lists of the system through the empty user connection (IPC$) after the default installation. This is to facilitate LAN users to share resources and files, but Any remote user can use this empty connection to get a list of your users. Hackers use this feature to find a list of users on the system and use some dictionary tools to attack the system. This is the more popular IPC attack on the Internet.
To prevent IPC attacks, you should start with the default configuration of the system. You can make up for the vulnerability by modifying the registry:
Step 1: Set the RestrictAnonymous item of HKEY_LOCAL_MacHINESYSTEMCurrentControlSetControlLSA to 1, you can disable empty user connections.
Step 2: Open the HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesLanmanServerParameters item in the registry.
For the server, add the key value AutoShareServer, type REG_Dword, with a value of 0.
At the client, add the key value AutoShareWks, type REG_DWORD, with a value of 0.
6. Reasonable management Administrator
Windows2000/XP system, after installation, the system will create an Administrator user by default, which has the highest management authority of the computer. Some users did not set a password for the Administrator user at the time of installation. Hackers use this to log in to the other computer using an advanced user. Therefore, individual users should properly keep the Administrator user information. When Windows 2000 logs in, it is required to enter the login password of the Administrator user. After Windows XP starts normally, the Administrator user cannot be seen. It is recommended that users using Windows XP enter the security mode and then control. Add a password to the Administrator user in the user account of the panel, or delete it to avoid hidden dangers.
A powerful system requires multiple security settings to protect it. Only in a secure system environment, users can use it with confidence. If you are hesitant about whether your xp system is safe enough, then you may wish to come. Try it.
