Understanding Information Security Culture in an Organization: An Interpretive Case Study

Bess, Donald Arlo 01 January 2012 (has links)
Information systems are considered to be a critical and strategic part of most organizations today. Because of this it has become increasingly important to ensure that there is an effective information security program in place protecting those information systems. It has been well established by researchers that the success of an information security program is heavily dependent upon the actions of the organizational members that interact with the information security program. Because of the interaction between people and the information security program an appropriate information security culture is required to effectively influence and control the actions of the members within that organization. While the importance of an information security culture has been well established by researchers there has been little research conducted to date that assist in understanding and managing information security culture within organizations. To expand the body of knowledge in this area this study will explore the information security culture of a large organization using interpretive case study methodology. The use of semi-structured interviews to collect data has allowed the researcher to report back their interpretation of shared meanings, consciousness, language and artifacts observed while at the research site. Structuration theory was applied as a theoretical lens with which to better understand information security culture and explore ways in which organizations can better understand and manage information security culture. We found structures of signification and legitimacy were the most influential on employee's behavior towards information security. While the structure of domination exerted minimal influence over employee's behavior. This research study contributes to the existing body of knowledge regarding information security culture by examining the role of structural properties exhibited within information security culture. Structural properties of information security culture have not been adequately considered within the existing literature. By expanding our understanding of the role of social structures such as systems of meaning, power and legitimacy on information security culture researchers will have a deeper understanding of this phenomena call information security culture. This will enable us to better understand how to develop and manage an appropriate information security culture.

Extracting Windows event logs using memory forensics

Veca, Matthew 18 December 2015 (has links)
Abstract Microsoft’s Windows Operating System provides a logging service that collects, filters and stores event messages from the kernel and applications into log files (.evt and .evtx). Volatility, the leading open source advanced memory forensic suite, currently allows users to extract these events from memory dumps of Windows XP and Windows 2003 machines. Currently there is no support for users to extract the event logs (.evtx) from Windows Vista, Win7 or Win8 memory dumps, and Volatility users have to rely on outside software in order to do this. This thesis discusses a newly developed evtxlogs.py plugin for Volatility, which allows users the same functionality with Windows Vista, Win7 and Win8 that they had with Windows XP and Win 2003’s evtlogs.py plugin. The plugin is based on existing mechanisms for parsing Windows Vista-format event logs, but adds fully integrated support for these logs to Volatility.

Behavioural monitoring via network communications

Alotibi, Gaseb January 2017 (has links)
It is commonly acknowledged that using Internet applications is an integral part of an individual’s everyday life, with more than three billion users now using Internet services across the world; and this number is growing every year. Unfortunately, with this rise in Internet use comes an increasing rise in cyber-related crime. Whilst significant effort has been expended on protecting systems from outside attack, only more recently have researchers sought to develop countermeasures against insider attack. However, for an organisation, the detection of an attack is merely the start of a process that requires them to investigate and attribute the attack to an individual (or group of individuals). The investigation of an attack typically revolves around the analysis of network traffic, in order to better understand the nature of the traffic flows and importantly resolves this to an IP address of the insider. However, with mobile computing and Dynamic Host Control Protocol (DHCP), which results in Internet Protocol (IP) addresses changing frequently, it is particularly challenging to resolve the traffic back to a specific individual. The thesis explores the feasibility of profiling network traffic in a biometric-manner in order to be able to identify users independently of the IP address. In order to maintain privacy and the issue of encryption (which exists on an increasing volume of network traffic), the proposed approach utilises data derived only from the metadata of packets, not the payload. The research proposed a novel feature extraction approach focussed upon extracting user-oriented application-level features from the wider network traffic. An investigation across nine of the most common web applications (Facebook, Twitter, YouTube, Dropbox, Google, Outlook, Skype, BBC and Wikipedia) was undertaken to determine whether such high-level features could be derived from the low-level network signals. The results showed that whilst some user interactions were not possible to extract due to the complexities of the resulting web application, a majority of them were. Having developed a feature extraction process that focussed more upon the user, rather than machine-to-machine traffic, the research sought to use this information to determine whether a behavioural profile could be developed to enable identification of the users. Network traffic of 27 users over 2 months was collected and processed using the aforementioned feature extraction process. Over 140 million packets were collected and processed into 45 user-level interactions across the nine applications. The results from behavioural profiling showed that the system is capable of identifying users, with an average True Positive Identification Rate (TPIR) in the top three applications of 87.4%, 75% and 61.9% respectively. Whilst the initial study provided some encouraging results, the research continued to develop further refinements which could improve the performance. Two techniques were applied, fusion and timeline analysis techniques. The former approach sought to fuse the output of the classification stage to better incorporate and manage the variability of the classification and resulting decision phases of the biometric system. The latter approach sought to capitalise on the fact that whilst the IP address is not reliable over a period of time due to reallocation, over shorter timeframes (e.g. a few minutes) it is likely to reliable and map to the same user. The results for fusion across the top three applications were 93.3%, 82.5% and 68.9%. The overall performance adding in the timeline analysis (with a 240 second time window) on average across all applications was 72.1%. Whilst in terms of biometric identification in the normal sense, 72.1% is not outstanding, its use within this problem of attributing misuse to an individual provides the investigator with an enormous advantage over existing approaches. At best, it will provide him with a user’s specific traffic and at worst allow them to significantly reduce the volume of traffic to be analysed.

SECURITY PRACTICES: KEEPING INDIVIDUALS SAFE AND AWARE IN THE CYBER WORLD

Respicio, Annie 01 June 2019 (has links)
We currently live in a day and age where nearly everyone uses electronic devices and connects to the web. Whether it be from a desktop, laptop, or smartphone, staying connected and having information at your fingertips is easier than ever. Although technology has become so intermingled with our daily lives, the idea around security is not as momentous as it should be. As mentioned by the Multi-State Information Sharing and Analysis Center (MS-ISAC), “based on recent statistics, the average unprotected computer can be compromised in a matter of minutes. The majority of individuals who thought their computers were safe…were wrong.” (MS-ISAC 2) This paper specifically investigates what types of security practices individuals in Southern California are aware of, how much of these practices are actively implemented and how can we not only further spread awareness, but also keep them engaged in these practices. This study shows that most of the participants feel confident about their level of knowledge regarding basic cyber security practices. Similarly, they were also confident in their active and frequent implementation of security practices. Nonetheless, it is imperative that implementing security measures become an active part of people’s behavior. As technology and interconnectedness continues to grow, security will only become even more at risk. Since it is a difficult task to change the behavior of people, this study suggests the best route is to begin consistently teaching people at a young age. By doing so, many of these practices can become embedded within people and nearly function as second nature as they mature. Although this suggestion does not focus on security awareness and implementation on those individuals who currently use smartphones, computers, and other devices, it is a sure way of ensuring the future populations become more engaged in understanding the importance of security measures and practice them.

Time trends and advertising presentation of information security advertisement

Weng, Wen-di 08 October 2004 (has links)
There are many studies about information security, but merely limited in the technologic and managerial fields. The purpose of this research is to discover information security advertisement in two ways ¡V the time trends and the advertising presentation. The research uses the content analysis with four variances ¡V time, category of products, type of enterprises, and targeted customers to analyze information security advertisement on computer magazines in the past ten years (1994~2003). According to research findings, there are some obvious changes in category of product, appeal strategy, amount of advertising message, topic reply and brand image in time trends. On the other hand, picture-headline effect, proportion structure, appeal strategy, presentation type, and brand image have apparent differences in advertising presentation. It can be concluded to eight findings from research results: 1.¡¨product¡¨ is always the main marketing objective; 2.advertising presentation is from ration to emotion; 3.follow the ¡§product life period¡¨ and ¡§advertising strategy¡¨ rule; 4.the amount of topic reply has gradually decreased; 5.different advertising purposes have different advertising presentation; 6.¡§expression of safety¡¨ is primary objective; 7.huge amounts of image usage; 8.the amount of advertising messages in information security advertisement is more than other types of advertisements.

Information security management in Australian universities : an exploratory analysis

Lane, Tim January 2007 (has links)
Australian Universities increasingly rely on Information Technology (IT) systems for essential business operations, including administration, teaching, learning and research. Applying information security to university IT systems is strategically important to maintaining overall business continuity in universities. However, the process of effectively implementing information security management in the university sector is challenging for security practitioners. University environments consist of a cultural mix of academic freedoms, student needs and compliance mandates. Consequently, unique and divergent demands are placed on securing and accessing university IT systems. This research undertook a qualitative based exploratory analysis of information security management in Australian universities. The aims and objectives of the research (represented as the research questions) were to determine: 1) What is the current status of information security management practices in the Australian university sector? 2) What are the key issues and influencing factors surrounding the effectiveness of information security management practices? 3) How could improvements in information security management be achieved? The findings from the research led to a comprehensive and insightful examination of the current status, issues and challenges facing information security practitioners in Australian universities. The research findings culminated in the development of a Security Practitioner's Management Model. An essential aim of the model is to assist security practitioners to successfully implement and progress information security in the Australian university environment. The research improves current understanding of information security issues and reinforces the pertinence of information security management as a strategically important business function for Australian universities.
