The U.K.'s appalling losses from business crimes amount to .75 million pounds a year from burglary alone. Organizations often react to crime without a thorough understanding of specific security needs or familiarity with technological options. The commercial aspects of security programming concern employees, professional service agencies, competitors, and creditors. The custody, processing, and disposal of information and documents should be controlled to forestall security breaches. Command of the legal aspects of security involves knowledge of national security legislation, as well as regulations stipulated in local by-laws and by professional institutions and trade unions. Managers must be familiar with court procedures, specialized legal institutions, and their diverse personnel, appeal procedures, and dispute solution mechanisms. An organization's financial safeguards require competent accounting, auditing, and internal control systems to forestall fraud and embezzlement. Special measures must be taken with cash and wage payment security, and with receipt, storage, and issue of goods. Sales income, credit control, and computer operations likewise demand specialized security planning. Both deterrence and detection capability must be considered in the choice of equipment. Charts and an index are provided. Appendixes include common abbreviations in security literature, glossaries, Parliamentary acts relevant to security, and trade directory headings for security equipment.
