XP system security mechanism

First, perfect user management function
Windows XP uses Windows 2000/NT kernel, very safe in user management. 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 uses "transparent" to isolate and use unreliable and potentially harmful code for user data, which can protect Keep your computer safe from viruses, Trojans, and worms that spread through email or web pages.
Third, support NTFS file system and encrypted file system EFS
The encrypted file system (EFS) in Windows XP is based on the public key, and uses the default EFS settings of the 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 "lack off" & rdquo;
2, the system comes with Internet connection Firewall
Comes with an Internet firewall that supports LAN, VPN, dial-up connections, and more. Support “custom settings & rdquo; and & ldquo; log view & rdquo;, for the security of the system to build a "hacker defense line".
