If the security of an operating system is relatively weak, it is not likely to have wide application in business. However, this kind of situation is absolutely not allowed by Microsoft Corporation. In fact, Microsoft Corporation has released many operating systems with high security. For example, as one of the most classic operating systems, Windows XP is equipped with various security mechanisms.
Windows XP security mechanism
If the security of Windows XP can’t be guaranteed, its market share will not be able to reach the expectation of Microsoft. Therefore, many Windows XP security mechanisms, such as user management function and software restriction policy have been adopted for the purpose of high security. Now, we’d like to explain them one by one:
Windows XP security mechanism one: complete user management function
Employing the kernel of Windows 2000/NT, Windows XP is very safe in user management. By setting folder security options of NTFS, Windows XP administrators are able to restrict users’ access to folders. In this way, the system will warn when a normal user tries to access other users’ documents. Windows XP administrators can also enable the auditing function for a file (or folder) to record users’ access situation of this file (or folder) to secure log files so as to further strengthen the supervision of file operations. User management function is indeed useful.
Windows XP security mechanism two: transparent software restriction policy
Windows XP software restriction policy provides a transparent way to isolate or prevent those untrusted and potentially harmful codes. In this case, users will be away from all kinds of losses caused by viruses, Trojans and worms through email and internet. Software restriction policy is able to protect the system against attacks of infected e-mail attachments. Meanwhile, transparent software restriction policy can also protect users from being attacked by the embedded URL/UNC links of untrusted Web pages in started Internet Explorer or other applications.
Windows XP security mechanism three: support of multiple users to encrypting file system
The encrypting file system of Windows XP has been greatly improved to allow multiple users to access the encrypted documents simultaneously. Users can encrypt a file or folder through setting its encryption attributes. Once a folder is encrypted, all files and subfolders created in or added to this folder will also be encrypted automatically. Therefore, the implementation of cryptographic operations on folder is advisable.
Windows XP security mechanism four: secure network access feature
In previous versions, Windows systems will always keep a few “back doors”. However, there are three new features in Windows XP: automatic update of patch, close of “back door” and the built-in internet connection firewall (which is one of the most important features of Windows XP).
Windows XP security mechanism five: security improvements in Ethernet
Secure Wireless/Ethernet LAN increases the ability to develop secure wired network and wireless local area network. This feature is actually accomplished by allowing the deployment of server on an Ethernet or wireless LAN. The Secure Wireless/Ethernet LAN in Windows XP achieves high security on the basis of wired and wireless LAN in IEEE 802.11 specification.
