Use Win7 Disk Quota Management to lock hackers out of the door

In most cases, hackers must upload Trojans or backdoors to the remote system to intrude into the remote system. To prevent such attacks, you must think of one thing: how can we cut off the hacker's path?

In fact, the disk quota function in the NTFS file system can help you easily manage disk space usage!

The following soft media provides a graphic description of this function, which is effective for Windows 7, Vista, and XP systems.

1. Open "computer" (the Windows XP system opens my computer). First, right-click an NTFS partition in the system and select "properties ", you can open the "partition property Settings" window, select the "quota" option, and click "display quota Settings", as shown in:

2. Check "enable quota management" and "Deny disk space to users who have exceeded the quota". All the quota options will be available. Then select the "disk space limit" option. In this case, we can specify the size of the disk space used by users in the system, such as 1 kb. in this way, if you pass in a file larger than 1 kb in the partition, the file will be rejected by the system and cannot be smoothly transmitted to the partition.

3. Similarly, there is a "Warning Level" option under the "disk space limit" option. If the file size at the warning level is set, when the user exceeds the warning level during disk space usage, the system will prompt the user that the file has exceeded the warning level in the disk quota.

4. Finally, the user can select "record events when the user exceeds the quota limit" and "record events when the user exceeds the warning level, in this way, if other users in the system exceed the partition warning level and quota limit, the system will automatically record these events to the system log, which is very helpful for the Administrator to monitor the system partition space.

5. After setting these configuration options, click the "OK" button in the window to complete the preliminary configuration of the Disk Quota function. You can be surprised to find that, there are still a lot of partitions available, and there is little space available now !!

6. At this time, you cannot write files larger than the quota to this partition. This configuration takes effect for all users in the system, including users in the Administrators group.

7. However, if the configuration takes effect for all users in the system, it is obviously inconvenient for users to perform operations on the system, in addition, the disk quota function provides a function to allocate space for different users. The implementation method is also very simple.

First, click the "quota items" button in the quota Configuration window. The "partition quota items" window is displayed. Click the "quota" option in the upper-left corner of the window, for example:

Then, select "new quota item", as shown in,

In this case, a user selection window is displayed, where you can enter or select a user name (such as Ruanmei.com) in the system. After confirmation, a disk space restriction option is displayed for this user, you can reasonably specify the space for the user based on the user's permissions and usage in the system, so that the configuration does not affect the normal operations of the system, it also enhances system security.
