an hp.com URL and uses the same HTTP protocol to download the files. Administrators should be

aware that this might constitute a security weakness in their particular environment.

To address this weakness, administrators and users can download HP printer and MFP firmware in

self-extracting, signed files as follows:

1. Use Internet Explorer to visit the HP Support and Drivers Web pages at hp.com for a particular

product model.

3. On the Download Drivers and Software page, select the file to download, and then click

Download.

4. On the Do you want to run or save this file? dialog box, click Run. The file is downloaded, and

the Do you want to run this software? dialog box appears.

5. Verify that the publisher displayed is HP.

6. Optionally, click HP to examine the digital signature information.

7. If the publisher information is correct, click Run to extract the driver from the self-extracting file.

8. To upload the extracted firmware image to HP Web Jetadmin, go to Device Management >

Firmware > Repository, and then click Import.

NOTE At this time, HP does not sign firmware image downloads (DLD files) for HP Jetdirect print

servers.

Device disk security

Managing device credentials and passwords primarily prevents unauthorized management and

configuration. The following are other ways to protect devices. HP Secure Erase technology is applied

in two different ways to remove data from storage devices.

• Secure File Erase—Erases files on

a continuous basis as soon as

they are no longer needed to

perform the requested function.

This feature controls the way a

device deletes its files on an

ongoing basis and is set in the

File System category (Figure 14).

The mode in which a device

erases its files can be set to

Non-secure Fast Erase, Secure

Fast Erase, or Secure Sanitizing

Erase.

• Secure Storage Erase—Removes

all non-essential data from

storage devices in a manner

consistent with preparation for decommissioning or redeployment. This operation can be initiated

on demand or scheduled for a later time. Secure Storage Erase is a device feature that can be

invoked from the Storage tab on any device list for one or more devices. When this feature is

invoked, it clears all the user files from the disk in one of the three erase modes.
