3 Terms and Definitions Definitions: Clearing Clearing is the process of eradicating the data on media before reusing the media so that the data can no longer be retrieved using the standard interfaces on the instrument. Clearing is typically used when the instrument is to remain in an environment with an acceptable level of protection. Sanitization Sanitization is the process of removing or eradicating stored data so that the data cannot be recovered using any known technology. Instrument sanitization is typically required when an instrument is moved from a secure to a non-secure environment such as when it is returned to the factory for calibration. (The instrument is declassified.) Agilent sanitization procedures are designed for customers who need to meet the requirements specified by the US Defense Security Service (DSS). These requirements are outlined in the Clearing and Sanitization Matrix issued by the Cognizant Security Agency (CSA) and referenced in National Industrial Security Program Operating Manual (NISPOM) DoD M ISL 01L-1 section Security erase Security erase is a term that is used to refer to either the clearing or sanitization features of Agilent instruments. Instrument declassification A term that refers to procedures that must be undertaken before an instrument can be removed from a secure environment such as is the case when the instrument is returned for calibration. Declassification procedures will include sanitization and or removal. Agilent declassification procedures are designed to meet the requirements specified by the DSS NISPOM security document (DoD M chapter 8). 3

5 Memory Clearing, Sanitization and/or Removal Procedures for 5000A/6000A This section explains how to clear, sanitize, and remove from you instrument for all that can be written to during normal operation and for which the clearing and sanitization procedure is more than trivial (such as rebooting your instrument).

6 User and Remote Interface Security Measures USB Mass Storage Device Security The user is responsible for providing security for the I/O ports for remote access by controlling physical access to the USB ports. Remote Access Interfaces The user is responsible for providing security for the I/O ports for remote access by controlling physical access to the I/O ports. Instrument should only be connected to a secure network or left unconnected. The I/O ports must be controlled because they provide access to all user settings, user states and the display images. The I/O ports include USB device, GPIB and LAN. Procedure for Declassifying a Faulty Instrument If the instrument is not functioning, proceed with one of the following options: 1. Boot from USB mass storage device with the latest firmware version loaded in the USB s root directory, and attempt to recover the instrument to full functionality. If this works, skip step If option 1 fails. Power the oscilloscope off and send the oscilloscope to your local Agilent service center for repair. 6
