Patch refers to a small program released to solve problems (generally discovered by hackers or virus designers) exposed during the use of large software systems (such as Microsoft operating systems).

Just like clothes that need to be patched when they are rotten, it is impossible for people to write perfect programs, so software will inevitably have bugs, and patches are specially made to fix these bugs because the originally released software has flaws. , after discovering it, compile a small program to make it perfect. This small program is commonly known as a patch. Patches are made by the original author of the software and can be downloaded from the website.

Extended information

Research shows that vulnerabilities in operating systems and application software often become entry points for security attacks. The most direct and effective way to solve vulnerability problems is to apply patches, but patching is a relatively passive method. For enterprises, the related patching processes such as collection, testing, backup, and distribution are still a rather cumbersome process, and even Patches themselves have the potential to become new vulnerabilities.

To solve the confusion of patch management, we first need to establish an automated patch knowledge base covering the entire network. The second step is to deploy a distribution system to improve patch distribution efficiency. Not only the patch management program, but the entire vulnerability management system also needs to be integrated with other security systems such as the enterprise's anti-intrusion system and anti-virus system to build a complete line of risk management defense.
