who have access to the printing system, as well as limiting what

they can bring to, or remove from, the printer environment.

Controlling access to critical files

A combination of fonts, logos, signatures, and forms are used in

developing a Xerox MICR application. One approach to securing

these files is to place them on media that can be physically

secured.

The Xerox MICR fonts are supplied on CD ROMs in the ship kit for

the printers. These fonts can be loaded on the printer prior to

printing the MICR document, deleted from the printer after all

MICR jobs have been printed, and physically secured while the

diskette is not in use.

For PCL fonts (such as MICR, signature, and logo fonts), you

must restart the system after deleting the fonts, to ensure that the

fonts are completely removed from the system.

Securing paper stocks

The ability of the Xerox MICR printing system to print a form,

signature, logo, and MICR line on a check at the same time as the

variable data eliminates the security problems involved in keeping

a supply of preprinted checks in storage.

However, because the security paper constitutes one of several

resources used to print the checks, securing the paper stock is a

wise extra precaution. Paper stock should be kept in locked

storage, in sealed boxes, with each ream separately wrapped and

sealed.

The amount of paper brought out of storage for printing can be

used as an audit cross-check against the number of sheets

printed. After the check sheets are printed, the stacked

documents should be carefully secured, because loose sheets are

susceptible to pilfering.

Responsible presence

The key to physical security in any document generation process

is a responsible presence. An individual or group must have the

responsibility of safeguarding the printing process. For critical

applications, the responsibility usually lies with the auditing

operation. In small organizations, the printer operator may be

responsible for security.

Physical security, and the presence of a responsible individual or

group whenever the system and supplies are not secured, can

create a higher level of security. Thus, two persons can have

custody of the printing facility, either by dual-key access to the

physical media or by knowledge of a password to access the data

files and run the print job.
