The chasm in the protection of classified information in South African government indicates that all the departments have at their disposal information that is to some extent sensitive in nature and obviously requires security measures. This study shows that government officials who in their official duties come to contact with classified information are either vulnerable or are implementing the security controls incorrectly. It is also clear that in the absence of a comprehensive statutory framework, the government departments’ classified information has resulted in an unstable and inconsistent classification and declassification environment. The statutory framework would, in addition to other things, address the rising threat of espionage and antagonistic activities, the selling of information and the protection of critical records in government, without hindering the constitutional rights of citizens to access information. This would create a system of valuable informantion and clarify which information requires security measures with respect to the protection of classified information. / Kgaohanao e tshireletsong ya tlhahisoleseding e sireleditsweng ke mmuso wa Afrika Borwa e supa hore mafapha ohle a ona a na le tlhahisoleseding eo, ka ho hong, e leng ya sephiri mme e hloka maemo a tshireletso.

La pratique quotidienne d'une activité génère un ensemble de connaissances qui se traduisent par un savoir-faire, une maîtrise, une compétence qu'une personne acquiert au cours du temps. Pour les préserver, la capitalisation des connaissances est devenue une activité essentielle dans les entreprises. Nos travaux de recherche ont pour objectif de modéliser et mettre en œuvre un système afin d'extraire et de formaliser les connaissances issues des anomalies qui surviennent dans un contexte de production industrielle et de les intégrer dans un framework facilitant la maintenance corrective et préventive. Ce framework structure la connaissance sous la forme de groupes d'anomalies. Ces groupes peuvent être rapprochés des patterns : ils représentent un problème auquel une ou plusieurs solutions sont associées. Ils ne sont pas définis a priori, c'est l'analyse des anomalies passées qui génère des groupes pertinents, qui peuvent évoluer avec l'ajout de nouvelles anomalies. Pour identifier ces patterns, supports de la connaissance, un processus complet d'extraction et de formalisation de la connaissance est suivi, Knowledge Discovery in Databases. Ce processus a été appliqué dans des domaines très variés. Nous lui donnons ici une nouvelle dimension, le traitement d'anomalies et plus particulièrement celles qui surviennent au cours de processus de production industrielle. Les étapes génériques qui le composent, depuis la simple sélection des données jusqu'à l'interprétation des patterns qui supportent les connaissances, sont considérées pour affecter à chacune un traitement spécifique pertinent par rapport à notre contexte applicatif.

The protection of security information in government departments requires the active engagement of executive management to assess emerging threats and provide strong security risk control measures. For most government departments, establishing effective protection of security information is a major initiative, given the often continuous, strategic nature of typical security efforts. This requires commitments or support from senior management and adequate resources. It necessitates the elevation of information security management to positions of authority commensurate to the required responsibilities. This has been the trend in recent years as government departments are increasingly dependent on their information assets and resources, while threats and disruptions continue to escalate in frequency and cost. It is clear from numerous recent studies that organisations that have taken the steps described in this research document and have implemented effective information security risk control measures have achieved significant results in reduced losses and improved resource management. Given the demonstrable benefits, it is surprising that there have not been greater progress in effectively managing information assets. Although regulatory compliance has been a major driver in improving the protection of security information overall, this study has also shown that nearly half of all government departments are failing to initiate meaningful compliance efforts. Failure to address the identified vulnerabilities by government departments will result in espionage, covert influencing manipulation, fraud, sabotage and corruption. Information security risk control measures include the elements required to provide senior management assurance that its direction and intent are reflected in the security posture of the organisation by utilising a structured approach to implement an information security programme. Once those elements are in place, senior management can be confident that adequate and effective protection of security information will protect, as far as possible, the department’s vital information assets. / Criminology and Security Science / M.
