Abstract
CONTROL PROCEDURES BEFORE A COMPUTER SYSTEM IS INSTALLED ARE EXAMINED, INCLUDING A PRELIMINARY SURVEY, ESTABLISHMENT OF STEERING COMMITTEE, A FEASIBILITY STUDY, AND SELECTION OF EQUIPMENT AND SERVICES. A REVIEW OF SPECIAL ORGANIZATIONAL CONTROLS NEEDED IN A COMPUTER SYSTEM COVERS DIVISION OF DUTIES, FUNCTIONS OF A DATA CONTROL GROUP, AND REPORTS TO SENIOR MANAGEMENT. CONTROL ELEMENTS INVOLVED IN DEVELOPING AND TESTING A NEW SYSTEM ARE EXAMINED, EMPHASIZING COOPERATION BETWEEN DATA PROCESSING PERSONNEL AND OTHER DEPARTMENTS. METHODS ARE THEN OUTLINED TO ENSURE EFFECTIVE PRODUCTION BY COMPUTER PERSONNEL AND TO PROVIDE PHYSICAL SECURITY FOR INFORMATION STORED IN THE COMPUTER FACILITY. CONTROL TECHNIQUES WHICH GUARANTEE THE COMPLETENESS, ACCURACY, AND AUTHORIZATION OF PROCESSED DATA OFTEN EXIST IN SEVERAL ALTERNATIVE FORMS, BUR ARE REVIEWED ACCORDING TO THE COMMON CATEGORIES OF HARDWARE, INPUT AND OUTPUT, AND PROGRAMMED CONTROLS. ALSO COVERED ARE OBJECTIVES AND PROCESSES OF DOCUMENTATION, SUCH AS OPERATING STANDARDS, MANUALS, FILE MAINTENANCE, AND FILE PROTECTION. FINALLY, OUTSIDE DATA CENTERS AS ALTERNATIVES TO A COMPANY'S PURCHASING ITS OWN EQUIPMENT ARE CONSIDERED WITH REGARD TO SELECTION, INPUT AND OUTPUT CONTROLS, AND SECURITY OVER CUSTOMER DATA. CHARTS ARE USED THROUGHOUT THE TEXT, AND A GLOSSARY OF TECHNICAL TERMS IS PROVIDED. A SUMMARY OF THE CONTROL OBJECTIVES, MINIMUM CONTROL STANDARDS, AND CONTROL TECHNIQUES DETAILED IN THE REPORT IS APPENDED FOR EASY REFERENCE. (MJM)
