MICR User Guide 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. 23
