This article will explain in detail what is the security loophole in the computer that belongs to the operating system itself. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

The security loophole that belongs to the operating system itself is the "back door" of the operating system itself. Vulnerabilities are defects in the specific implementation of hardware, software, protocols, or system security policies, which can enable an attacker to access or destroy the system without authorization.

Vulnerabilities are defects in the specific implementation of hardware, software, protocols, or system security policies, which can enable an attacker to access or destroy the system without authorization. For example, logic errors in Intel Pentium chips, programming errors in earlier versions of Sendmail, weaknesses in authentication methods in NFS protocols, and improper configuration when setting anonymous Ftp services by Unix system administrators may be used by attackers to threaten the security of the system. Therefore, these can be regarded as security loopholes in the system.

Vulnerability refers to the weakness or flaw of a system, the sensitivity of the system to a specific threat attack or dangerous event, or the possibility of the threat effect of an attack. The vulnerabilities may come from defects in the design of the application software or operating system or errors in coding, or from design defects in the interactive processing of the business or unreasonable logical processes. These defects, errors, or irrationality may be exploited intentionally or unintentionally, thus adversely affecting the assets or operations of an organization, such as information systems being attacked or controlled, important data stolen, and user data tampered with. The system is used as a springboard to invade other host systems. Judging from the loopholes found at present, the vulnerabilities in the application software are far more than those in the operating system, especially the WEB application system accounts for the vast majority of the information system vulnerabilities.

I. the relationship between vulnerabilities and specific system environments and their time-related characteristics

Vulnerabilities will affect a wide range of software and hardware devices, including the system itself and its supporting software, network client and server software, network routers and security firewalls. In other words, there may be different security vulnerabilities in these different hardware and software devices. There will be different security vulnerabilities in different kinds of software and hardware devices, between different versions of the same device, between different systems composed of different devices, and under different setting conditions of the same system.

The problem of vulnerabilities is closely related to time. From the day of the release of a system, with the in-depth use of users, the loopholes in the system will continue to be exposed, and these previously discovered vulnerabilities will continue to be patched by the system vendor. Or be corrected in a later release of the new version of the system. While the new version of the system corrects the vulnerabilities in the old version, it will also introduce some new vulnerabilities and errors. Therefore, with the passage of time, old loopholes will continue to disappear, new loopholes will continue to appear. The problem of loopholes will also persist for a long time.

Therefore, it is meaningless to discuss vulnerabilities apart from the specific time and specific system environment. We can only talk about the possible vulnerabilities and feasible solutions according to the actual environment such as the system version of the target system, the software version running on it and the service running settings.

At the same time, it should be noted that the research on vulnerabilities must track the latest developments of the current computer systems and their security problems. This is similar to the study of the development of computer viruses. If you can't keep track of new technologies at work, you won't have a say in talking about system security vulnerabilities, and even previous work will gradually lose value.

Second, the harm of loopholes and its prevention

The existence of loopholes can easily lead to the invasion of hackers and the presence of viruses, which will lead to data loss and tampering, privacy disclosure and even loss of money, such as websites being invaded because of loopholes. Website user data will be leaked, website functions may be destroyed, and even the server itself will be controlled by the intruder. At present, with the development of digital products, loopholes extend from computers as carriers to digital platforms, such as mobile phone QR code vulnerabilities, Android application vulnerabilities and so on.
