What are the security mechanisms of win7 all 5

1.Protect the kernel.

The kernel is at the heart of the operating system, which makes it a prime target for malware and other attacks. Basically, if an attacker is able to access or manipulate the kernel of an operating system, they can execute malicious at a level that is undetectable by other applications or even by the operating system itself. Microsoft has developed "kernel-mode protection" to protect the core and ensure that there is no unauthorized access.

2.Protection mechanisms.

User Account Control (UAC) is a great example of what Windows Vista is a love-hate experience for us all. With Win7, UAC is still there, but Microsoft has added a slider that allows us to control ourselves the level of protection that UAC provides - so that the number of pop-ups is limited by the number of files allowed to be accessed and executed.

Pop-ups are only a small aspect of what UAC can do. Under Windows Vista, many users simply disable all UACs, but that also disables protected mode IE and some other operating systems. In Win7, the slider is set to the same protection as Windows Vista by default, but you can customize it in the Control Panel.

3.Security tools and applications.

Due to kernel protection and other changes made by Microsoft, old antivirus and other security software are not compatible with Win7 in terms of how or not applications are allowed to interact with the core functions of the operating system. Developers like McAfee, Symantec, Trend Micro, and other security software developers offer Win7-compatible versions, but if you don't want to invest more money, Microsoft also offers free security tools to protect Win7.

Windows Firewall and Windows Defender anti-spyware tools are included in the base installation package for Windows 7. You can also install Microsoft Security Essentials, a free antivirus recently released by Microsoft. However, all of the above mentioned all of this needs a premise to be guaranteed, that is, genuine win7 system, which is the most important point to ensure the safety and reliability of the personal computer, otherwise everything is empty talk. ■
