Development of an IT-Security Performance Measurement System

Inhaltsangabe:Abstract:
Adequate security of information and the systems that process it is a fundamental management responsibility. Management must understand the current status of their IT-Security program in order to make informed decisions.
In this context, this Bachelor Thesis proposes a Performance Measurement System for IT-Security, which is designed to be well-balanced and comprehensive. It views IT-Security from four perspectives: Organisational, Financial, Operational and Personnel.
The documentation of the system contains the key figures and their interrelationships. With its modular design, it can either be used out-off-the-box or tailored to the specific requirements of the organisation.
Chapter 1 briefly discusses the reason for this Bachelor Thesis and introduces the problem statement. Chapter 2 explores the basic concepts behind both IT-Security and performance measurement. Chapter 3 covers general requirements, which are fundamental principles needed to be taken into consideration when building an IT-Security Performance Measurement System. Chapter 4 describes the approach taken for the design of the system. Chapter 5 introduces the Performance Measurement System for IT-Security.
