3.0 IT Security Management


As the requirement for information technology grows, the complexity of people's requirements has grown continuously. Increasingly, implementation and maintenance of a reasonable level of IT security is requiring planned and organised action on the part of all those involved. The efficient implementation of IT security measures and review of their efficacy therefore necessitates a well thought out, controlled IT security process. This planning and control task is referred to as IT security management. It is imperative that functional IT security management is established at the start of the IT security process.

However, functional IT security management must be integrated into the existing management structures of a given organisation. It is therefore virtually impossible to specify a single IT security management structure will be directly usable within every organisation. Instead, modifications to organisation-specific circumstances will frequently be necessary.

This chapter is intended to present a systematic approach to establishing functional IT security management and improving it over time in line with developments in business operations. The approach presented is therefore intended to be viewed as a framework which can be modified in line with specific characteristics of a given organisation.

Note: In some other sections of this manual the term IT security management is also used to refer to the IT Security Management Team, i.e. to that group of persons which is responsible for the IT security process within an organisation.

Threat Scenario

Safeguard S 2.191 Establishment of the IT security process should be worked through at the outset in every case. This safeguard describes a procedure for initiating and implementing a complete IT security process. The steps and activities which are necessary for this are described, and these in turn are covered in detail in the safeguards which follow.

The safeguards package for the area "IT security management" is summarised below.
