the first step in implementing any security process must

include a means of controlling the group of people 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 DocuPrint MX MICR fonts are supplied on one 3.5-

inch diskette 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, 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,
