Introduction to WinXP Security Mechanism

Although WinXP has withdrawn from the historical arena, there are still many users who choose to use it. Everyone is most concerned about the security of WinXP system. In fact, WinXP itself comes with a very secure mechanism, which is not so easy to be invaded by the outside world. The following small series brings you a comprehensive understanding of what is WinXP security mechanism.

First, the perfect user management functions

Windows XP using Windows 2000 /NT kernel, in the user management is very safe. Any additional users can see it when they log in. Unlike Windows 2000, users who have been added an administrator group by hackers can't find it. Using the NTFS file system, you can restrict user access to a folder by setting a folder's security options, such as when a normal user accesses another user's document. You can also enable auditing for a file (or folder) and log the user's access to the file (or folder) to a security log file to further enhance the supervision of file operations.

Second, transparent software restriction policy

In Windows XP, the software restriction policy is to isolate and use unreliable and potentially harmful user data in a "transparent" manner. The code that protects your computer from viruses, Trojans, and worms that spread through email or web pages to keep your data safe.

Third, support NTFS file system and encrypted file system EFS

The encrypted file system (EFS) in Windows XP is based on public key, and uses the default EFS setting of CryptoAPI structure, EFS can also Use the extended Data Encryption Standard (DESX) and Triple-DES (3DES) as encryption algorithms. Users can easily encrypt files.

When encrypting, EFS automatically generates an encryption key. When you encrypt a folder, all the files and subfolders in the folder are automatically encrypted, and your data is more secure.

Fourth, secure network access features

The new features are mainly in the following aspects:

1, the patch is automatically updated, for users "ldrink" & rdquo; Br>

2, the system comes with Internet connection firewall

Comes with Internet firewall, supports LAN, VPN, dial-up connection, etc. Support “custom settings & rdquo; and & ldquo; log view & rdquo;, for the security of the system to build a "hacker defense line".

It can be seen that WinXP's own security mechanism still has a certain protective effect. As long as we do not often touch some problem websites, we will not be attacked by the outside world. Coupled with the help of some security software today, we have reason to believe that the classic WinXP system can still play for a few more years!
