Do you understand? The eight ultimate weapons in Win XP SP2

        On August 6, 2004, Microsoft finally released XP SP2 to the computer manufacturer. This marks that XPSP2 has passed the final test, and the RTM (a version provided to the manufacturer) stage, the end user will gradually get XP in a few weeks. SP2. This is nine months behind the initial expected time, a year and a half away from the previous service pack for Windows XP. What is the most advanced XPSP2 in history, which is the ultimate weapon that has been long-awaited? Let us explore it together. One of the ultimate weapons: Windows has a security master installed XPSP2 can start to see the security center window (shown in Figure 1), it is a web-based application, you can directly view the relevant Set the security options and set them.

Since most users don't know if their system is in a safe state, this leaves an opportunity for viruses or hackers to invade. The Windows Security Center monitors whether the system security components are working properly, and it can identify whether the Windows Firewall, Automatic Updates, and anti-virus software are working properly in the shortest amount of time. For normal settings, the Security Center will be displayed in green; if the corresponding option is abnormal (for example, turned off or disabled), it will be marked in red; if the status is unknown, it will be indicated in yellow (this compares the options on the anti-virus software) Common, mainly because some anti-virus software may not be recognized by the system for some reason. But don't worry, it doesn't mean that the anti-virus software doesn't work or is not compatible with the system. The red warning and the yellow error just indicate that the anti-virus software can't Security Center view). It is important to note that although firewalls and anti-virus software can be set up through the Security Center, these functions are not provided by the Security Center. The Security Center only serves as a centralized management. The ultimate weapon of the second: Windows Firewall new appearance In XPSP2, the once Internet ribbed ICF (Internet Connection Firewall) with a new look - Windows Firewall debut (as shown in Figure 2).

Since it is called Windows Firewall, it should be functionally valid for the entire Windows and not just for network connections. In fact, the Windows Firewall is a core security component in XPSP2, and it has become an indispensable security guard. Compared with the original ICF, there has been a significant improvement. 1. Global configuration, valid for all network connections. Change the problem that ICF must be configured separately for a single network connection. 2. Allow network connection configuration for an application (previous ICF is not acceptable), with the basic functions of the firewall. 3. Make it possible for network services to be effective in a designated network area. Windows Firewall can be divided into a range of network connections. For example, you can limit the scope of file and printer sharing to a network area (such as a subnet or IP range) that you specify, and computers outside this area cannot use the sharing feature. 4. Security protection at the start time. With previous Windows XP, there was a delay between when the computer entered the active state on the network and when the ICF began to protect the connection. This delay leaves an opportunity for unsolicited traffic to attack the computer during startup. Now, only DNS and DHCP are allowed during the startup process. Other network services must wait for the Windows firewall to work before it can be used. Hackers then want to attack at startup. 5. Windows Firewall also modified compatibility and can coexist peacefully with most programs. Although Windows Firewall provides a lot of features, it is relatively thin compared to professional-level firewall software. The ultimate weapon of the third: IE refuses to disturb to ensure stability As the most used web browser, IE's function and security has been receiving a lot of attention. 1. Reject pop-up window interruptions Before XPSP2, various ad pop-up window blocking plug-ins emerged in an endless stream, even Microsoft added this feature in its own MSN Toolbar. Now, with XPSP2, these plugins can be discarded, because Microsoft has also added a blocking ad pop-up window in IE6SP2 (Figure 3).

2. Manage IE add-ons In order to enjoy various conveniences when surfing the Internet, many users have installed various IE plug-ins, such as Flash ActiveX plug-ins. More plug-ins, Internet access may be very convenient, but if there are plug-ins "fighting" each other, IE will be overwhelmed, at any time on the verge of collapse. The "Add-on Management" feature has been added to IE6SP2 to control plugin conflicts. Add-ons, which you can install or not, can be disabled after installation. These settings can be easily done in the add-on management component (Figure 4).

3. Ensuring the security of downloaded files As the release idea of ​​XPSP2, it has also been widely embodied in IE6SP2. IE6SP2 will judge whether the downloaded file is masqueraded (MIME sniffing) according to its file content rather than the file extension, and according to the security of the downloaded file, a corresponding graphical warning prompt is given at the bottom of the download information dialog box. In addition, security enhancements including locking local computer areas, unauthorized ActiveX execution restrictions, digital signature control, MSJVM security settings, and IE binary behavior security settings are also added to XPSP2. Although XPSP2 provides a number of security settings, many security settings are not enabled by default for compatibility. Users need to edit the registry or modify Group Policy to use it. Fortunately, Microsoft has provided a number of guiding articles on XPSP2 security settings on its website. It is not difficult to enable these security settings. Tip: Add-ons A variety of programs that add functionality to the browser. Such as extra toolbars, animated mouse pointers, etc. The common MSN Toolbar is in the scope of add-ons.
