As you know, in most cases hacking remote systems must upload trojans or backdoor programs to the remote system. Then, to guard against it, surely think of a point: how to cut off the hacker's path?
In fact, the disk quota feature in the NTFS file system can help users easily manage disk space!
The following software for this function to make a graphic description of Windows7, Vista system and even XP are effective.
1, open "Computer" (XP system is to open My computer), first, click the right mouse button on an NTFS partition in the system, select Properties, you can open the Partition Properties Settings window, select the Quota option, and click Show quota settings, as shown in the following figure:
2, first check "Enable quota management" and "deny disk space to exceed the quota limit of users," then all the quota options will become an optional state. Then select the disk space limit option, where we can specify the amount of disk space that the user in the system uses, such as 1KB. So if a user passes in a partition with a file greater than 1KB, the file is rejected by the system and cannot be successfully passed into the partition.
3. Similarly, under the disk space limit option, there is also a warning level option, and if a warning level file size is set, the user is prompted to exceed the warning level when using disk space, and the system prompts users that the file exceeds the warning level in disk quotas.
4, the final user can be selected on the "user exceeds the quota limit when the record event" and "users exceed the warning level logging event" two options, so if the system has other users exceeding the warning level of the partition and quota limit, the system will automatically record these events in the system log, It is very helpful for the administrator to monitor the system partition space.
5, when the completion of these configuration options settings, click the window under the "OK" button, you can complete the disk quota function of the initial configuration, then the user can be surprised to find that there are many remaining space of the partition, now free space has become very little!!
6, the user has been unable to write to this partition is larger than the quota file. And this configuration takes effect for all users in the system, including users in the Administrators group.
7, but if the configuration for all users of the system, it is obviously inconvenient for users to operate the system, but also in the disk quota function provides a space for different users to partition the function. The implementation method is also very simple.
First, click the Quota Entry button in the Quota Configuration window, which will pop up the partition Quota Entries window and click the Quota option at the top left of the window, as shown below:
Then, select New quota entry in it, as shown in the following illustration,
A user's window will pop up, fill it in or select a user name (such as ruanmei.com) in the system, and then there will be an option to use disk space limits for that user, depending on the user's permissions and usage in the system. A reasonable use of space for the user, so that the configuration does not affect the normal operation of the system, but also enhance the security of the system.
