Efficient and Appropriate Use ensures that the company’s IT resources are used for the purposes for which they were intended, in a manner that does not interfere with the rights of others. Availability is concerned with the full functionality of a system (e. g. finance or payroll) and its components. The potential causes of these losses are termed “threats”. These threats may be human or non-human, natural, accidental, or deliberate. 2. Domains of Security. This policy will deal with the following domains of security: • Computer system security: CPU, Peripherals, OS.

This includes data security. • Physical security: The premises occupied by the IT personnel and equipment. • Operational security: Environment control, power equipment, operation activities. • Procedural security by IT, vendor, management personnel, as well as ordinary users. • Communications security: Communications equipment, personnel, transmission paths, and adjacent areas. Reasons for IT Security Confidentiality of information is mandated by common law, formal statute, explicit agreement, or convention. Different classes of information warrant different degrees of confidentiality.

The hardware and software components that constitute the company’s IT assets represent a sizable monetary investment that must be protected. The same is true for the information stored in its IT systems, some of which may have taken huge resources to generate, and some of which can never be reproduced. The use of company IT assets in other than in a manner and for the purpose for which they were intended represents a misallocation of valuable company resources, and possibly a danger to its reputation or a violation of the law. Finally, proper functionality of IT systems is required for the efficient operation of the company.

Some systems, such as the web administration, data-base administration, order processing, and accounting systems are of paramount importance to the mission of the company.
