Procedural security deals with the establishment and enforcement of security procedures. Some of these procedures may be independent of the type or types of computers involved. Others may not. For example, perimeter security controls are usually similar for all type of systems. But desktop computers may require forms of antitheft protection not required by mainframes.
Procedural security regulates the performance of duties associated with system operation and use, and with the physical storage of system information. Common security practices include partitioning computer operating duties, using several operators, and storing backup tapes at bonded, offsite depositories. Procedural security also encompasses and may regulate company policies that deal with information security, such as policies that regulate the way individuals manage their own passwords.
