Enhancing Security Win XP's Top Ten Service References: Windows provides a lot of very valuable services, but many services are double-edged swords. Many security risks. The following ten services are services that pose a greater threat to security. It is recommended that ordinary users must disable it. Services that Win XP must ban 1.NetMeeting Remote Desktop Sharing: Allow authorized users to access each other on the network through NetMeeting. This service is not very useful for most individual users, and the opening of the service will also bring security problems, because the service will send the user name in clear text to the client connecting it, and the hacker's sniffing program is very These account information can be easily detected. 2.Universal Plug and Play Device Host: This service is for general plug-and-play devices. There is a security hole in this service, and computers running this service are vulnerable. An attacker who sends a fake UDP packet to a network with multiple Win XP systems may cause these Win XP hosts to attack the specified host (DDoS). In addition, if a UDP packet is sent to the system port 1900, and the address of the "Location" field is pointed to the charging port of another system, it may cause the system to enter an infinite loop, consuming all the resources of the system (required when installing hardware) Manually turned on). 3. Messenger: Commonly known as messenger service, computer users can use it for data exchange in the LAN (transmitting Net Send and Alerter service messages between client and server, this service has nothing to do with Windows Messenger. If the service stops, Alerter will not Being transmitted). This is a dangerous and annoying service. The Messenger service is basically used in enterprise network management, but spammers and spammers often use the service to post pop-up ads under the heading “Courier Service”. And this service has loopholes, and MSBlast and Slammer viruses use it for rapid propagation. 4.Terminal Services: Allows multiple users to connect and control one machine and display desktops and applications on remote computers. If you don't use Win XP's remote control feature, you can disable it. 5.Remote Registry: Enables remote users to modify the registry settings on this computer. The registry can be said to be the core content of the system. Generally, users do not recommend changing it themselves, let alone others to modify it remotely, so this service is extremely dangerous. 6.Fast User Switching Compatibility: Provides management for applications that need assistance under multiple users. Windows XP allows fast switching between multiple users on a single computer, but this feature has a vulnerability. When you click "Start →Logout & Rarr; Fast Switch", enter a user repeatedly in the traditional login mode. When the name is logged in, the system considers it to be brute force and locks all non-administrator accounts. If you don't use it often, you can disable it. Or cancel “Use Fast User Switching" in “Control Panel →User Account →Change User Login or Logout Mode”. 7. Telnet: Allows remote users to log in to this computer and run programs, and supports a variety of TCP/IP Telnet clients, including UNIX and Windows-based computers. Another dangerous service, if started, remote users can log in, access local programs, and even use it to modify network settings such as your ADSL Modem. Unless you are a network professional or your computer is not being used as a server, be sure to disable it. 8.Performance Logs And Alerts: Collect performance data from local or remote computers based on pre-configured schedule parameters, then write this data to a log or trigger an alert. In order to prevent data from being searched by remote computers, it is strictly prohibited. 9.Remote Desktop Help Session Manager: If this service is terminated, Remote Assistance will not be available. 10.TCP/IP NetBIOS Helper: NetBIOS is often used by people to attack under Win 9X. For users who do not need file and print sharing, this item can also be disabled. Advanced services can be disabled. Services that can be banned as needed: 1. Alerter: Notifies selected users and computers about system management level alerts. If you are not connected to the LAN and do not need to manage alerts, you can disable them. 2. Indexing Service: Indexed content and attributes of files on local and remote computers, providing quick access to files. This service is of little use to individual users. 3. Application Layer Gateway Service: Provides support for third-party protocol plug-ins for Internet Connection Sharing and Internet Connection Firewall. If you don't have Internet Connection Sharing or Windows XP's built-in firewall enabled, you can disable this service. 4.Uninterruptible Power Supply: Manages the uninterruptible power supply connected to the computer. Users who do not have a UPS installed can disable it. 5.Print Spooler: Load the file into memory for printing later. If the printer is not installed, it can be disabled. 6. Smart Card: Manages the computer's read access to the smart card. Basically not used, you can disable it. 7.Ssdp Discovery Service: Starts automatic discovery of upnp devices on the home network. There are not many devices with upnp, and this service is useless for us. 8.Automatic Updates: Automatically update patches from the Windows Update network. Using the Windows Update function to upgrade, the speed is too slow, it is recommended that you download the patch to the local hard disk through the multi-threaded download tool, and then upgrade. 9. Clipbook: Enable “Clipboard Viewer Store information and share it with remote computers. If you do not want to share information with a remote computer, you can disable it. 10.Imapi Cd-burning Com Service: Imapi management CD recording, although this feature is built into Win XP, most of us will choose professional burning software, and if you do not have a recorder installed, you can also disable the service. 11.Workstation: Create and maintain a client network connection to the remote service. These connections will not be available if the service is stopped. 12.Error Reporting Service: Error reporting is allowed when services and applications are running in a non-standard environment. If you are not a professional, this error report is useless to you. Then there are the following services that have no effect on the average user. You can decide on your own choices, such as: Routing and Remote Access, Net Logon, Network DDE, and Network DDE DSDM.
