Information security has become a much discussed subject all over the world in the last few years. This is because information security is no longer a luxury, but a necessity in all organisations. The securing of information is not an easy task because information security is flexible and always seems to be in a state of development. This means that information security has undergone different development changes due to new technologies in the past few years. Information security became prominent around 50 years ago and had a very strict technical approach. In this approach, industries mainly worked with mainframes, with little or no concept of management aspects such as security policies or awareness programmes. The technical approach thus included little or no management effort in terms of information security. The need to manage information security began when new technologies such as the Internet and the World Wide Web were introduced to the information security environment. This caused information security to shift from the technical to the more managerial approach. The move of information security from the technical to the managerial approach may be identified through different development trends. These development trends have occurred mainly to improve information security management in any organisation. The primary purpose of this dissertation is therefore to identify and investigate different development trends that have an influence on information security, especially from a managerial point of view. / Prof. J.H.P.
