Repudiation

Repudiation is using a device without leaving usage information. This includes preventing the device

from logging data or bypassing security checks such as user authentication. This also includes finding

ways to use an MFP without paying by bypassing job accounting software. Examples include:

 Accessing usage logs to delete entries

 Removing origination information from file metadata

 Bypassing user authentication

 Using remote management software to access the device

You can minimize the risks of repudiation in the following ways:

 Enable IPSec to encrypt the data stream to include log data and file metadata

 Close unused ports and protocols

 Save copies of log data at a separate location

 Add security solutions such as smartcard, swipe-card and thumbprint readers

Information Disclosure

Information disclosure is gathering information from a device and providing it to unauthorized users.

This can include authentication information, usage log information, or information from the contents of

a job. Such data stored on your hard drive is considered ‘at rest’ while data being transmitted by

your MFP device is considered ‘in transit. Examples include:

 Reading stored print jobs on the device hard drive.

 Downloading log information

 Downloading address books

 Intercepting print jobs, copy jobs, fax jobs, or digital send jobs (such as email)

You can minimize the risks of information disclosure in the following ways:

 Enable IPSec to protect data in transit

 Use hardware encryption to protect data at rest

 Close unused ports and protocols

 Configure all possible password settings

 Configure authentication

 Configure SNMPv3 for Web Jetadmin

Denial of Service

Denial of service is any type of interference with normal use of an MFP. Examples include:

 Canceling or pausing the print jobs of others

 Turning off the device remotely

 Disconnecting power to the device

 Removing the device formatter board

 Disconnecting the device from the network

 Causing interference with network communication to the device

 Changing the network location of the device

 Causing an error state that interrupts service

 Changing access configurations

Here are some methods of minimizing opportunities for denial of service on a device:

 Lock the control panel

 Lock EWS configuration settings
