Management of security information in the security industry

Govender, Doraval 06 1900 (has links)
Incidents, threats and vulnerabilities have the potential to negatively affect an organisation’s assets. Information on these incidents, threats and vulnerabilities are important to security. It is therefore necessary for this security information to be effectively and efficiently managed, so that correct decisions may be made on the implementation of security risk control measures. This study explored the management of security information in the security industry by undertaking the following: • establishing the “status quo” of the collection and analysis of security information and the implementation of security risk control measures in practice; • identifying the nature and extent of problems experienced in the collection and analysis of security information and the implementation of security risk control measures; and the • discovery of a new Security Information Management Model (SIMM). Mixed methods research was used to study the management of security information in the security industry. The explorative research design was used for this purpose. Semi-structured and focus group interviews were conducted with senior security managers and operational security officers, respectively. The grounded theory research design was used to analyse the qualitative data in order to generate a substantive grounded theory. The theory is that security officers operate without a standardised framework to manage security information. The data from the semi-structured and the focus group interviews were used to design a questionnaire to conduct a survey using the quantitative approach. The non-experimental research design was used to conduct this self-administered questionnaire survey. The data from this questionnaire survey helped validate and confirm the substantive grounded theory. The study found that there was the need for a Security Information Management Model to manage security information in the security industry. Based on this finding the researcher recommended a new Security Information Management Model for the management of security information in the security industry. / Criminology and Security Science / D.

The psychological effects experienced by computer forensic examiners working with child pornography

Whelpton, Juliette 02 1900 (has links)
Convergence of technology has made access to the Internet faster, easier and cheaper. Criminals, including paedophiles, child abusers and pornography traders make use of this technology to commit criminal offences. Computer Forensic Examiners (CFEs) are members of the Cyber Crime Unit, a professional, specialised unit of the South African Police Service (SAPS) who are responsible for computer forensic examination including the investigation of child pornographic images. The aim of the study was to seek understanding on what psychological effects the CFEs experienced when working with the images and was conducted from within the social constructionism and the narrative frameworks. The images had a severe impact on the CFEs as was clearly uncovered in the stories of six CFEs who participated in this study. The participants' stories were recorded and transcribed after which the application of thematic content analysis found that the participants all suffered similar negative effects. These findings were integrated with the findings of a focus group as well as with the findings of a similar study that was conducted during the same time by the Crimes against Children Research Center at the University of New Hampshire and resulted in identifying symptoms of trauma and stress experienced by the CFEs. Based on these results recommendations regarding the support for the CFEs were made. / Psychology / M.A. (Psychology)

Les caractéristiques individuelles, de l'événement criminel et de l'enquête criminelle en matière d'homicides sexuels sériels et non-sériels

James, Jonathan 05 1900 (has links)
Au cours des trois dernières décennies, plusieurs modèles théoriques de l’homicide sexuel ont été proposés. Ces modèles ont suggéré qu’il existe une diversité de facteurs associés à la commission d’un ou de plusieurs homicides sexuels, notamment des facteurs développementaux, psychologiques et de l’événement criminel et ont permis de proposer un profil des individus ayant commis un homicide sexuel. Cependant, aucun de ces profils n’a intégré l’ensemble de ces facteurs en un tout cohérent. De plus, ces modèles et profils, à l’exception du modèle proposé par des chercheurs associés au Federal Bureau of Investigation, ont été réalisés à partir d’échantillons d’individus ayant commis un seul homicide sexuel. En conséquence, bien que ces modèles et profils proposent une explication de l’émergence de ces comportements, ils ne permettent pas d’expliquer dans quelles circonstances ceux-ci se répètent et prennent fin. Étant donné que ces modèles et profils n’ont pas pris en considération les caractéristiques du parcours de vie de l’individu après la commission du premier homicide sexuel, ceux-ci n’intègrent pas de paramètres post-homicides, tels que les paramètres de l’enquête criminelle. En conséquence, il existe actuellement peu de certitudes concernant les caractéristiques du profil des individus pouvant constituer des facteurs permettant potentiellement d’expliquer pourquoi certains individus commettront une série d’homicides sexuels tandis que d’autres n’en commettront qu’un. L’objectif principal de cette thèse est d’identifier les caractéristiques distinctives des individus ayant commis une série d’homicides sexuels, afin de proposer des profils d’individus sériels et non-sériels. Afin d’atteindre cet objectif, une série d’études comparatives entre des individus ayant commis des homicides sexuels en série (HSS; n = 33) et des individus ayant commis un seul homicide sexuel (HS; n = 87) ont été réalisées. Les résultats de cette étude mettent en évidence que les caractéristiques qui distinguent les sériels des non-sériels ne se limitent pas à des facteurs individuels ou à la façon dont les individus commettent leur crime, mais aussi à l’échec des intervenants de l’enquête criminelle à appliquer les pratiques considérées comme étant indispensables à la résolution rapide d’un homicide. D’autre part, les résultats de cette étude mettent en évidence qu’il existe deux principaux profils d’individus ayant commis un homicide sexuel, celui des HSS et celle des HS. Finalement, les résultats de cette étude ont servi de fondations au développement d’un modèle conceptuel théorique de l’homicide sexuel sériel et non-sériel qui permet d’expliquer dans quelles circonstances le phénomène semblerait émerger, se répéter et prendre fin. / Over the last three decades, many theoretical models of sexual homicide have been proposed, which have made it possible to propose a profile of individuals. Although these models and profiles have suggested associations between the commission of one or more sexual homicides and a wide variety of factors—notably developmental, psychological, and crime-phase—none has produced a unified vision of sexual homicide that takes into account all factors. Moreover, these models and profiles, with the exception of that of the US Federal Bureau of Investigation, have been based on samples of individuals having committed a single homicide. As a result, although they propose explanations of the emergence of sexual homicide, current models and profiles are silent on the determinants of its repetition and cessation. Additionally, these models and profiles do not address post-homicide parameters, such as those related to the criminal investigation, since they do not take into account the sexual murderer’s life course following the commission of the homicide. For all these reasons, considerable uncertainty remains about why some individuals commit a series of sexual homicides while others commit only one. The principal objective of this thesis’s research was therefore to identify the distinctive characteristics of individuals having committed a series of sexual homicides, in order to proposed profiled of serial and nonserial sexual murderers. To this end, comparative analyses of serial sexual murderers (HSSs; n = 33) and nonserial sexual murderers (HSs n = 87) were conducted. The results indicate that the two groups of participants in this sample can be distinguished not only on individual factors and the manner in which the homicide was committed, but also on the failure of criminal investigators to apply best practices and rapidly resolve the homicides. Finally, this thesis’ research establishes a foundation for the development of theoretical models of serial and nonserial sexual homicide that explain the circumstances responsible for the emergence, repetition, and cessation of this phenomenon.

Perceptions and experiences of investigators in the SAPS regarding the application of polygraph in criminal investigations

Gumala, Manjula 21 January 2021 (has links)
In spite of the SAPS having a dedicated polygraph capacity since 1998, little research has been conducted with regard to the use of the polygraph in criminal investigations. Consequently, the aim of this research was to focus on the perceptions and experiences of investigators in the SAPS regarding the application of polygraph testing in criminal investigations, the application of the polygraph as an investigative aid, the extent to which it is used by SAPS investigators to resolve criminal cases opened by the general public and/or in internal departmental criminal investigations; and whether or not it has helped to solve cases by giving direction and/or focus to the investigator when an investigation is at an impasse. A qualitative research approach was conducted among investigators within the SAPS. The research design selected for this study was grounded theory. The sample consisted of twenty investigators, ten of whom had previously used polygraph examinations in their investigations and ten of whom had not. Data was collected from interviews, document analysis, field notes and memoranda which presented and detailed the perceptions and experiences of investigators in the SAPS regarding the application of polygraph tests in criminal investigations. / Criminology and Security Science / M.A. (Criminology)

The use of Automated Fingerprint Identification System in identifying fraudulent voters’ registration in Lesotho

Chigando, Lesole John January 2018 (has links)
The research was prompted by constant criticism of the Independent Electoral Commission (IEC) because of its poor voter registration and voters’ roll. Free and fair elections are the strong arm of democracy. The identified research problem was investigated by means of qualitative research. A thorough literature study from various sources of information, a case file analysis and structured interviews were used to gather the required data. The interviews were conducted with fingerprint experts, a data processor and constituency electoral assistants from the Lesotho Mounted Police Service, the National Identity and Civil Registry at the Ministry of Home Affairs and the IEC respectively. It was found that using fingerprints and the Automated Fingerprint Identification System (AFIS) can assist in investigations and in combating voter’s fraud, as fingerprints are unique. AFIS can be utilised for various purposes by institutions in the private and public sectors. Like any apparatus, AFIS has its own strengths and weaknesses. / Criminology and Security Science / M.

Utilisation of the financial intelligence centre as a crime intelligence source

Mostert, Derick 11 1900 (has links)
The research was conducted as a result of the researcher‟s concern that the possibility exists that members of the different law enforcement agencies in South Africa might have a misconception about the mandate and functions of the Financial Intelligence Centre. If such a misconception in fact exists, it poses a huge challenge towards fruitful co-operation among the Centre and the different law enforcement agencies. The researcher identified certain practical problems, namely, that investigators are not aware of the types of intelligence that the Centre could provide them with, and that investigators might not be informed about the specific procedures to follow when they need to request intelligence from the Centre. The research has shown that, in the past, the Centre has been a useful source of crime intelligence concerning a range of predicate offences including narcotics, fraud and tax related crimes. The research has further found that, although the majority of participants gained a lot of experience in law enforcement and investigations, they had limited awareness about the Financial Intelligence Centre and its functions. This research project studied the utilisation of the Financial Intelligence Centre as a crime intelligence source. / Police Practice / M. Tech. (Forensic Investigation)

Les facteurs favorisant la réussite de l'instigation en matière de drogues à Montréal en 2018

Robitaille, Maurice Jr 08 1900 (has links)
La montée de la nouvelle gestion publique est « l’une des tendances internationales les plus marquantes de l’administration publique » (Hood, 1991). Les services de police n’ont pas été épargnés par ce nouveau type d’administration (Dupont, 2003). C’est dans ce contexte de reddition de compte, de gestion entrepreneuriale, de contraintes économiques, de recherche de l’efficacité et de l’efficience que de nombreuses études sur l’évaluation et la performance de la police ont été effectuées à partir des années 1970, notamment en lien avec la priorisation des dossiers et les facteurs favorisant sa résolution. La présente étude s’inscrit dans cette visée d’évaluation des enquêtes criminelles, plus particulièrement à l’efficacité et l’efficience de la gestion des enquêtes en matière de drogues et les facteurs favorisant sa réussite. La présente étude a pour but de répondre à trois objectifs. Le premier objectif est de dresser un portrait détaillé des dossiers d’instigation en matière de drogue au SPVM en 2018. Le second objectif est, de façon exploratoire, de tester la transférabilité du modèle de l’instigation de Kilfeather (2011) à l’instigation en matière de drogue au SPVM en 2018. Enfin, le troisième objectif, directement en lien avec l’efficacité policière, est d’identifier les facteurs non institutionnels et institutionnels qui favorisent la réussite de l’instigation. Des analyses descriptives ont été produites afin de répondre aux deux premiers objectifs et des régressions logistiques et linéaires ont été utilisées afin de dégager les facteurs favorisant la réussite de l’enquête en matière de drogue à Montréal en 2018. L’analyse descriptive des 324 dossiers d’enquête en matière de drogue à Montréal en 2018 permet de constater un processus similaire à Kilfeather (2011) dans lequel trois éléments sont essentiels dans ce type d’enquête, soient l’utilisation d’une source humaine, l’utilisation de la surveillance physique et la saisie de drogue, lors d’une perquisition ou par un agent d’infiltration. Les analyses multivariées de l’étude suggèrent que, pour les trois définitions de la réussite qu’est la résolution, l’arrestation et la soumission d’une demande d’intenter des procédures, les trois facteurs significatifs qui favorise la réussite sont le fait que l’infraction est commise sur la voie publique, le fait que le suspect se déplace en véhicule et le nombre de surveillances. / The rise of new public management is "one of the most significant international trends in public administration" (Hood, 1991). The police services were not spared by this new type of administration (Dupont, 2003). It is in this context of accountability, entrepreneurial management, economic constraints, the search for effectiveness and efficiency that many studies on the evaluation and performance of the police have been carried out based on 1970s, particularly in relation to the prioritization of files and the factors favoring its resolution. This study is in line with this aim of evaluating criminal investigations, in particular the effectiveness and efficiency of the management of drug investigations and the factors favoring its success. The present study aims to meet three objectives. The first objective is to draw up a detailed portrait of the drug instigation files at the SPVM in 2018. The second objective is, in an exploratory manner, to test the transferability of the model of Kilfeather's instigation (2011) to the drug instigation at the SPVM in 2018. Finally, the third objective, directly related to police efficiency, is to identify the non-institutional and institutional factors that promote the success of the instigation. Descriptive analyzes were produced in order to meet the first two objectives and logistic and linear regressions were used to identify the factors favoring the success of the drug investigation in Montreal in 2018. Descriptive analysis of the 324 files drug investigation in Montreal in 2018 reveals a process similar to Kilfeather (2011) in which three elements are essential in this type of investigation, namely the use of a human source, the use of physical surveillance and drug seizure, during a search or by an undercover officer. The study's multivariate analyzes suggest that, for the three definitions of success of resolving, arresting and submitting a lawsuit, the three significant factors that promote success are the fact that the offense is committed on public roads, the fact that the suspect is traveling in a vehicle and the number of watches.

An analysis of information in South African electronic newspaper articles on cash-in-transit robberies as a source of intelligence

Nemutshili, Tshianzi 01 1900 (has links)
The escalating number of cash-in-transit robberies in South Africa is of major concern and this requires information in South African electronic newspaper articles as a source of intelligence. The aim of this study is to determine if newspaper articles on Cash-in-transit robbery can be a source of intelligence. The researcher identified sources which can be used for data collection that could be turned into intelligence. Electronic newspaper articles were explored and turned into informative documents in terms of information that can be gathered about cash-in-transit robberies. The researcher discussed the available sources of intelligence and intelligence that can be gathered through newspaper articles. The researcher conducted the study with the purpose of exploring, describing, and empowering. Exploring existing method used to gather intelligence on crime and CIT robberies, exploring and the topic under investigation the by consulting national and international sources and local newspaper articles, in order to obtain new knowledge on the problem, exploring if newspaper articles could provide intelligence on CIT robberies, by examining existing literature to gather information about the sources of intelligence. Furthermore, the researcher also wanted to describe how newspaper articles can be used in the investigation of CIT robberies. Lastly, to ensure that this research is made available to other researchers who have an interest in exploring the sources of information and the crime intelligence-gathering process. To accomplish this, the researcher examined national and international literature found in textbooks, research articles; master’s dissertations and PhD theses; newspaper articles (online); and searched the internet with the intention of finding data that could answer the research questions. / Police Practice / M.A. (Criminal Justice)

Utilising advanced accounting software to trace the reintegration of proceeds of crime, from underground banking into the formal banking system

Botes, Christo 30 April 2008 (has links)
The aim of this paper is to research how advanced accounting software can be used by police detectives, financial risk specialists and forensic investigation specialists, who are responsible for the investigation and tracing of the reintegration of proceeds of crime, from underground banking into formal banking system (pro active and reactive money laundering investigation) with a view on criminal prosecution. The research started of by looking at the basic ways how proceeds of crime are smuggled before it is integrated into the formal banking system. In that context, the phenomenon of Underground banking was researched. Currency smuggling, Hawala currency transfer schemes and the way in which it is used to move proceeds of crime were discussed in detail. Thereafter Formal banking and the way in which proceeds of crime is reintegrated from underground banking structures into formal banking systems were discussed. The use of advanced accounting software to trace the point where proceeds of crime are reintegrated into formal banking were researched extensively. Accounting software and investigative techniques on how to trace financial transactions which might be tainted with proceeds of crime were discussed. Accounting software which can be used on office computers such as laptops were discussed and more advanced automated systems which can be used to trace proceeds of crime transactions in the formal banking systems were also discussed. In specific, the investigative techniques on how to use these systems as investigative tools were discussed in great detail. This research paper gives a truly unique perspective on the financial investigative and analytical angle on proceeds of crime and money laundering detection. / Criminal Justice / M.Tech.

Pointing out of crime scenes : a technique used to link a suspect with a crime

Van der Merwe, Dirk, 1964- 10 1900 (has links)
Crime in South Africa is very close to getting out of control. There is a dramatic increase especially in violent crimes such as murder, hijacking, business robberies, house robberies, rapes and armed robberies where innocent people get killed daily. This has the public shivering in fear. The South African Police Service are responsible for the prevention and investigation of all crimes committed. The Detective Service has the unpleasant task of hunting down the criminals that are responsible for committing these crimes. When a crime is committed and a suspect is arrested, the detectives must use all techniques and methods available to them to connect the suspect with the crime. The positive linkage of a suspect with a crime can lead to a conviction in court and one less criminal on the streets of South Africa. One technique that can be used is pointing out of a crime scene. This research is all about the pointing out of crime scenes. / Police Practice / M. Tech. (Forensic Investigation)
