Windows XP operating system security

Microsoft has boasted that "users of Windows XP will no longer need to worry about network access security," and that Windows XP is an NT-kernel operating system that is more powerful than any Windows system, but there are a number of worrying issues.

Let's take a look at the security of Windows XP, and first look at its advantages:

Safety

One, the consummation user manages the function

Windows XP uses the Windows 2000/nt kernel to be very secure in user management. Any additional users can see it when they log in, unlike Windows 2000, a user who has been added to an administrator group by hackers cannot find it. Using the NTFS file system, you can restrict user access to a folder by setting security options for a folder, such as a warning when a normal user accesses a document for another user. You can also enable auditing on a file (or folder), and log access to the file (or folder) to the security log file to further enhance the oversight of file operations.

Second, transparent software restriction policies

In Windows XP, software restriction policies isolate and use unreliable, potentially harmful code for user data in a "transparent" manner that protects your computer from all kinds of viruses, trojans, and worms that are transmitted via e-mail or Web pages, ensuring data security.

Iii. supporting the NTFS file system and Encrypting File System (EFS)

The Encrypting File System (EFS) in Windows XP is based on public keys and leverages the default EFS settings of the CryptoAPI structure, and EFS can also use the Extended Data encryption Standard (DESX) and Triple-des (3DES) As a cryptographic algorithm. Users can easily encrypt files.

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

Four, secure network access characteristics

The new features are mainly manifested in the following aspects:

1, Patch automatic Update, for users "burden"

2, the system with Internet Connection Firewall

Has an Internet firewall that supports LAN, VPN, dial-up connections, and so on. Support for "Custom settings" and "Log viewing" for the security of the system to build a "hacker defense."

3, close the "back door"

In previous releases, Windows systems had several "backdoor" ports, such as 137, 138, 139, which were "open doors," and are now closed in Windows XP.
