Many people's first reaction when they hear about a computer system vulnerability is that I want to fix it immediately, but do we actually understand it? the answer is negative. "Computer system vulnerabilities" may often pop up a window after the system starts to prompt the detection of high-risk vulnerabilities, so there must be some computer maintenance software on each of us, such as computer housekeeper.
But what we often hear does not mean that we also understand them. What harm will windows vulnerabilities cause to computers? Today, Sunflower will explain to you about the vulnerabilities of computer systems.
What are Windows System Vulnerabilities?
Windows system vulnerabilities refer to technical defects or program errors in the development process of the operating system. These defects may cause other users (such as hackers) to illegally access or use viruses to attack the computer system, thereby stealing important computer data and information, and even destroying the operating system. . Therefore, system developers (such as Microsoft) generally release the latest patches every month to fix newly discovered vulnerabilities.
Vulnerabilities will affect a wide range, including the system itself and its supporting software, network client and server software, network routers and firewalls, etc. In other words, there may be different vulnerability problems in these different software and hardware devices. Different types of software and hardware devices, different versions of the same device, different systems composed of different devices, and the same system under different setting conditions will have different vulnerabilities.
System vulnerabilities are mainly divided into two types, one is high-risk vulnerabilities, and the other is functional vulnerabilities:
1. High-risk vulnerabilities: system core and Office vulnerabilities, these vulnerabilities allow remote code execution, making the computer at risk of being hacked
2. Functional vulnerabilities: software version updates or adding practical functions to the system to solve common computer problems and improve computer performance
So what are the dangers of system vulnerabilities? Sunflower will explain to you.
1. System loopholes are often used by lawbreakers or hackers to forcefully install malicious programs, spread viruses, and implant Trojan horses to computers;
2. System loopholes can easily lead to the theft of important data and information of the computer. In severe cases, the operating system will be destroyed and all computer data will be lost;
3. In the LAN environment, it will also cause the spread of viruses, causing other computers to be paralyzed, which is extremely harmful;
4. The severely damaged operating system can only be solved by reinstalling the system, the tutorial diagram of reinstalling ghost win7 from the U disk.
Many people are curious, is it necessary to fix system vulnerabilities?
Failure to repair system vulnerabilities may not necessarily bring danger to the computer, but the probability of computer system being attacked will increase. Therefore, Sunflower recommends that you repair the "high-risk" vulnerabilities. As for other functional vulnerabilities, they are optional. Select the required patches and install them to avoid wasting system resources.
