The Information and Communications Technology (ICT) environment constitutes an integral part of our daily lives. Individual computer users and large corporate companies are increasingly dependent on services provided by ICT. These services range from basic communication to managing large databases with corporate client information. Within these ICT environments something is bound to go wrong for a number of reasons, which include an intentional attack on information services provided by an organisation. These organisations have in turn become interested in tracing the root cause of such an incident with the intent of successfully prosecuting a suspected malicious user.Digital forensics has developed significantly towards prosecuting such criminals. The volumes of information and rapid technological developments have contributed to making simple investigations rather cumbersome. In the digital forensics community a number of digital forensic process models have been proposed encapsulating a complete methodology for an investigation. Software developers have also greatly contributed toward the development of digital forensics tools. These developments have resulted in divergent views on digital forensic investigations. This dissertation presents the IDFPM -Integrated Digital Forensic Process Model.The model is presented after examining digital forensic process models within the current academic and law enforcement literature. An adapted sequential logic notation is used to represent the forensic models. The terminology used in the various models is examined and standardised to suit the IDFPM. Finally, a prototype supports a limited selection of the IDFPM processes, which will aid a digital forensic investigator. There are a great many things about architecture that are hidden from the untrained eye.-Frank Gehry Acknowledgements• Thank you God for giving me the strength, wisdom, endurance and the patience to do this, despite the constant challenges.• I would like to thank my mother and father, Gary and Magsie, for their constant support, love and encouragement.

Abstract:In every organisation an information security culture emerges from the way in which people behave towards information and the security thereof. The procedures that employees use in their daily work could represent the weakest link in the information security chain. It is therefore important to develop and improve information security culture through a structured model that addresses employee behaviour. This article will discuss the concept of information security culture and an assessment approach developed to implement and improve such a culture.
