M.Com. (Informatics) / The aim of this study is to introduce a model that can be used to manage the security profiles by using a role oriented approach. In chapter 1 the addressed problem and the aim of the study, are introduced. In chapter 2 the different approaches used in the management of security profiles and the security profiles in Computer Associates's TOP SECRET and IBM's RACF, are discussed, In chapter 3 the Model for Role Profiles (MoRP) is introduced and discussed. Chapter 4 consists of a consideration of the possible problems of MoRP and an extension of MoRP is discussed.' The extended model is called ExMoRP. Chapter 5 consists of an analysis of the Path Context Model (pCM) for security and the principles of the PCM are added to ExMoRP to enhance security. In chapter 6 ExMoRP, with the principles of the PCM, are applied on a case study: In chapter 7 a methodology for the implementation of ExMoRP in an environment, is introduced. In chapter 8 it is shown how the principles of ExMoRP can be applied in UNIX, In chapter 9 it is shown how the principles of ExMoRP can be applied in Windows NT. In chapter 10 it is shown how the principles of ExMoRP can be applied in ORACLE. Chapter 11 consists of a review of the management of security and the present trends.
