What are the vulnerabilities of operating systems?

1. There are generally two ways for Heirong to discover the vulnerabilities of the system, one is the accidental discovery (the so-called coincidence), and the other is the discovery based on the analysis after obtaining the core information.

2. Why are there vulnerabilities, to put it simply, there is basically no perfect thing in this world, and the same is true for computer operating systems.

1. The current mainstream system is very complex, and it is difficult for a complex thing to be perfect, which is the so-called fault and loophole. Just like the world's first central building, maybe the wind can't blow down, the ground can't move, and the plane will fall down as soon as it hits.

2. When a system is used, it may face a variety of situations, and many of them do not exist at the time of design. Or is it like the center of the world, who would have thought of hitting it with a plane! Taking a step back, even if you don't have to hit it with a plane, maybe the saboteurs will be able to enter through the sewers and vents and put bombs in ......

3. Therefore, if there is enough information to understand and study a complex system, many ways can often be found to destroy it and illegally tamper with it.

3. Why couldn't Microsoft find out in the first place?

It's too hard for Microsoft, and no company can make something perfect. What's more, one's own mistakes often can't be discovered by oneself, and that is also the most common law, the so-called authorities are confused.

The network is inseparable from the operating system, and the security of the operating system has a very important impact on the security of the network. The lack of the operating system is trapped, there are leaks in the source of the operating system program, and the improper configuration of the operating system program.

The SSR server security plus-fix system adopts the internal-core plus-fix technology, and sets up an independent and controllable security shell in the core-core layer of the existing commercial operating system to block the access to resources by blocking and intercepting threats to ensure that the personnel in the system are credible, the applications are trustworthy, and the permissions are controllable, so as to realize the last line of defense for the operating system to resist security attacks.

Use cracked programming tools; insecure programming habits; Ill-conceived architectural design.

System vulnerabilities refer to technical flaws or program errors in the development process of the operating system, which are often exploited by hackers to spread malicious programs to attack computer systems, such as web trojans.

Therefore, system vulnerabilities must be fixed in time to effectively prevent computers from being hacked. System developers typically release the latest patches every month to fix newly discovered vulnerabilities.

First of all, to be clear, the programmer may leave a backdoor in the hidden place of the program** to facilitate later debugging. If the operating system is compared to a building, then the application is the room in it, the system user is the occupant of the building, and the vulnerability is some doors and windows that should not exist, or a hole in the wall that inexplicably, these defects and problems can cause strangers to invade the building, so that the security of the building is threatened.

Taking the common Windows operating system as an example, its huge kernel leads to many unknown vulnerabilities, and a large number of intruders are constantly looking for vulnerabilities and stealing value information for profit. The "black box operation" attribute of the Windows operating system makes it impossible for ordinary users to obtain the source of the operating system**, and can only ensure system security through continuous update of patches by R&D personnel after the vulnerability is discovered.
