Some Finer-Grained Security
The basic setup I showed so far allows everyone on your network to have access to your USB drives. This may or may not be desirable. To restrict access to the networked USB drive, go to the Advanced tab of the DNS-120 web interface and create a user by filling out the form and providing a username and password. I created a user named "bicky," as shown in Figure 11.

From here, click the Folder button in the left navigation panel (see Figure 12).

Next, you can click the Modify Setting button (see Figure 13) to control access for a share.

Uncheck the All Accounts check box next to the User drop-down list. Then you can select users that you created earlier (in my case, the user "bicky"), as shown in Figure 14.

The user can be granted authority to read/write or read only. Figure 15 shows the successful granting of share access to my share for the user bicky.

As a result of the network access setting I've just defined, a user will have to provide the username (bicky, in this example) and associated password to connect to the share named USB_TO_I_a1 by using the Easy Search Utility, before being able to mount the USB drive across the network.
