360 security guards release system vulnerability patching "three principles"

Computer operating systems and software often expose various vulnerabilities, and Trojan viruses can invade computers at any time through these vulnerabilities. Just like a house has a crack, even if the door and window are locked, the thief can enter and exit freely. Therefore, we must promptly patch the vulnerability. However, patching is also a matter of learning. Scanned vulnerabilities and recommended patches vary widely using different operating systems, different software, and different patching tools. So, how can we fix the patch safely and scientifically?

360 security experts say, should be patched to fix high-risk security vulnerabilities as the main purpose, rather than play better. If you install blindly inappropriate or incorrect patches, you will not only waste system resources, but also cause blue screens or even crashes on your computer. Users of non-genuine Windows operating systems should pay special attention to patch screening. To this end, 360 security experts reminded netizens that patching needs to follow three principles: patching is not repeated, invalid patches should not be played, and risk patches are not easy to play.

patch a principle: do not repeat the patch has been installed to play

use a variety of third-party users may experience problems installing the patch when repeated patching tools. Some third-party patching tools often scan the vulnerabilities that have been fixed in the system in order to invite users to “defectively” to deceive users to repeatedly install patches. Because the Windows XP system does not have a verification mechanism for repeated patch installation, the same patch can be installed multiple times by different tools, which will not only improve the security of the system, but will occupy system resources and may even cause unknown problems. In response to such situations, the 360 ​​Security Guard can prompt the user to avoid loss due to repeated patching.

Principle Two: Invalid patch should not fight

invalid patch divided into four, namely: not suitable user operating system environment patch, patch the current software is not suitable for the environment, Expired patches and patches that fail to install repeatedly.

can imagine, the patch should not be mixed for different operating systems, such as Windows XP patch can not be installed on Windows 7 system; if you do not have to use a Microsoft software (system components), The corresponding patch should not be played. An outdated patch is an alternate version of Microsoft that has released a patch for a vulnerability and only needs to install the latest patch. In addition, some patches may experience repeated installation failures in non-genuine systems, because the files of such operating systems have been modified by third parties, making the official Microsoft patch invalid.

for the revocation patch, the user needs the patch tool to accurately identify and be shielded, otherwise the system is not only a waste of resources and time, and may result in abnormal.
Principle 3: Risk patches are not easy to play

Risk patches are patches with large compatibility issues with user systems, especially non-genuine Windows operating systems modified by third parties. Certain patches are particularly susceptible to system failure. According to user feedback, the 360 ​​Security Center found that multiple patches such as KB956572, KB971657, and KB977165 can easily cause some Windows operating system versions to fail, such as a blue screen on the computer, constant reboot, or inaccessibility to “safe mode”. For these patches with installation risks, 360 security guards classify them as “not recommended to install” patches, users should carefully install them. And 360 users only need to enable "trojan firewall" to ensure that the corresponding vulnerability will not be attacked.

360 security experts concluded that, if there are other ways users mistype more than three patches, 360 security guards will be automatically prompted to provide security for the user, informing the user to install the risks that may exist. As the most popular security software in China, 360 Security Guard is the preferred patching tool for most Internet users in China. It has accumulated rich experience in the identification, download and installation of patches, and has established a sound operational feedback mechanism to detect in time. A risk patch that can easily lead to system failure. At the same time, 360's "Repair Vulnerabilities" function intelligently and accurately recommends patches based on the user's computer system and software environment, rather than recommending all patches to the user.
