Abstract:

The paper is devoted to the issues of computer security assessment of instrumentation and control systems (I&C systems) of nuclear power plants (NPPs). The authors specified the main areas of assessing the computer security of NPP I&C systems, especially the assessment of cyber threats, vulnerabilities of I&C computer security, sufficiency of applied measures for ensuring I&C systems computer security, risks of I&C system computer security as well as periodic reassessment of I&C computer security. The paper considers the assessment of I&C computer security vulnerabilities, sufficiency of applied measures for ensuring I&C computer security (assessment of cyber threats and the risks of I&C computer security are discussed in detail in other publications from the series “Computer Security of NPP Instrumentation and Control Systems”). Approaches to assessing the computer security vulnerabilities of I&C systems and software at each stage of I&C life cycle are considered. The recommendations for assessing vulnerabilities regarding technical and software protection against unauthorized access or connection to I&C, protection of local networks, implementation of organizational measures and procedures for computer security are provided. The paper describes the scope and procedures for the initial assessment and periodic reassessment of NPP I&C computer security. Recommendations for the formation of an appropriate evaluation team are provided. Methods of assessing I&C computer security are considered, namely: analysis of documents (computer security policy, program, plan, reports, etc.), survey of staff (administrative, operational, service and computer security experts), direct review of I&C systems, their components and local networks. The evaluation stages (collection of information, detailed analysis, reporting) and the scope of work at each stage are described. General information about the possibility and necessity of assessing the computer security risks of I&C systems in the case of using risk-informed approaches is provided. The need to document the results of the assessment is noted separately and specific proposals about the procedure for developing relevant reports are made.

Abstract:

This study sought to identify the drivers of mobile money services development in Zimbabwe using Ecocash as a case study. Through purposive sampling, respondents were selected from financial institutions, regulatory bodies, customers, and agents. The research showed that in Zimbabwe the development of mobile money services is influenced by several factors such as a high mobile telephone penetration rate, a high number of unbanked people owing to poor access to traditional banking services, a lower level of internet penetration levels, customer awareness of the service because of aggressive branding, security and ease of use, and a dense networks of agents. Fast technology diffusion was also a factor that influenced the fast adoption of mobile money services in Zimbabwe. More research is needed to assess the impediments in countries where the adoption of mobile money services has not been as spectacular as in Zimbabwe or Kenya.

Abstract:

This dissertation concerns investigations on two of the most important problems in establishing communication security in computer networks: (1) developing a model which precisely describes the mechanism that enforces the security policy and requirements for a secure network, and (2) designing a key management scheme for establishing a secure session for end-to-end encryption between a pair of communicants. The security mechanism attempts to ensure secure flow of information between entities assigned to different security classes in different computer systems attached to a computer communication network. The mechanism also controls the accesses to the network devices by the subjects (users and processes executed on behalf of the users). The communication security problem is formulated by using a mathematical model which precisely describes the security requirements for the network. The model integrates the notions of access control and information flow control to provide a Trusted Network Base (TNB) for the network. The demonstration of security of the network when the security mechanism is designed following the present model is given by using mathematical induction techniques. The problem of designing key management schemes for establishing end-to-end encrypted sessions between source-destination pairs when the source and the destination are on different networks interconnected via Gateways and intermediate networks is examined. In such an internet environment, the key management problem attains a high degree of complexity due to the differences in the key distribution mechanisms used in the constituent networks and the infeasibility of effecting extensive hardware and software changes to the existing networks. A hierarchical approach for key management is presented which utilizes the existing network specific protocols at the lower levels and protocols between Authentication Servers and/or Control Centers of different networks at the higher levels. Details of this approach are discussed for specific illustrative scenarios to demonstrate the implementational simplicity. A formal verification of the security of the resulting system is also conducted by an axiomatic procedure utilizing certain combinatory logic principles. This approach is general and can be used for verifying the security of any existing key management scheme.

Abstract:

Slow and suspicious activities on modern computer networks are increasingly hard to detect. An attacker may take days, weeks or months to complete an attack life cycle. A particular challenge is to monitor for stealthy attempts deliberately designed to stay beneath detection thresholds. This doctoral research presents a theoretical framework for effective monitoring of such activities. The main contribution of this work is a scalable monitoring scheme proposed in a Bayesian framework, which allows for detection of multiple attackers by setting a threshold using the Grubbs’ test. Second contribution is a tracing algorithm for such attacks. Network paths from a victim to its immediate visible hops are mapped and profiled in a Bayesian framework and the highest scored path is prioritised for monitoring. Third contribution explores an approach to minimise data collection by employing traffic sampling. The traffic is sampled using the stratification sampling technique with optimum allocation method. Using a 10% sampling rate was sufficient to detect simulated attackers, and some network parameters affected on sampling error. Final contribution is a target-centric monitoring scheme to detect nodes under attack. Target-centric approach is quicker to detect stealthy attacks and has potential to detect collusion as it completely independent from source information. Experiments are carried out in a simulated environment using the network simulator NS3. Anomalous traffic is generated along with normal traffic within and between networks using a Poisson arrival model. Our work addresses a key problem of network security monitoring: a scalable monitoring scheme for slow and suspicious activities. State size, in terms of a node score, is a small number of nodes in the network and hence storage is feasible for very large networks.

Abstract:

Mobile ad hoc networks (MANETs) are generating much interest both in academia and the telecommunication industries. The principal attractions of MANETs are related to the ease with which they can be deployed due to their infrastructure-less and decentralized nature. For example, unlike other wireless networks, MANETs do not require centralized infrastructures such as base stations, and they are arguably more robust due to their avoidance of single point of failures. Interestingly, the attributes that make MANETs attractive as a network paradigm are the same phenomena that compound the challenge of designing adequate security schemes for these innovative networks.
One of the challenging security problems is the issue of certificate revocation in MANETs where there are no on-line access to trusted authorities. In wired network environments, when certificates are to be revoked, certificate authorities (CAs) add the information regarding the certificates in question to certificate revocation lists (CRLs) and post the CRLs on accessible repositories or distribute them to relevant entities. In purely ad hoc networks, there are typically no access to centralized repositories or trusted authorities; therefore the conventional method of certificate revocation is not applicable.
Another challenging MANET security problem is the issue of secure routing in the presence of selfish or adversarial entities which selectively drop packets they agreed to forward; and in so doing these selfish or adversarial entities can disrupt the network traffic and cause various communication problems.
In this thesis, we present two security protocols we developed for addressing the above-mentioned MANET security needs. The first protocol is a decentralized certificate revocation scheme which allows the nodes within a MANET to have full control over the process of certificate revocation. The scheme is fully contained and it does not rely on any input from centralized or external entities such as trusted CAs. The second protocol is a secure MANET routing scheme we named Robust Source Routing (RSR). In addition to providing data origin authentication services and integrity checks, RSR is able to mitigate against intelligent, colluding malicious agents which selectively drop or modify packets they are required to forward.

Abstract:

The corporate scandals of the last few years have changed the face of information security and its governance. Information security has been elevated to the board of director level due to legislation and corporate governance regulations resulting from the scandals. Now boards of directors have corporate responsibility to ensure that the information assets of an organisation are secure. They are forced to embrace information security and make it part of business strategies. The new support from the board of directors gives information security weight and the voice from the top as well as the financial muscle that other business activities experience. However, as an area that is made up of specialist activities, information security may not easily be comprehended at board level like other business related activities. Yet the board of directors needs to provide oversight of information security. That is, put an information security programme in place to ensure that information is adequately protected. This raises a number of challenges. One of the challenges is how can information security be understood and well informed decisions about it be made at the board level? This dissertation provides a mechanism to present information at board level on how information security is implemented according to the vision of the board of directors. This mechanism is built upon well accepted and documented concepts of information security. The mechanism (termed An Organisational Information Security Profile or OISP) will assist organisations with the initialisation, monitoring, measuring, reporting and reviewing of information security programmes. Ultimately, the OISP will make it possible to know if the information security endeavours of the organisation are effective or not. If the information security programme is found to be ineffective, The OISP will facilitate the pointing out of areas that are ineffective and what caused the ineffectiveness. This dissertation also presents how the effectiveness or ineffctiveness of information security can be presented at board level using well known visualisation methods. Finally the contribution, limits and areas that need more investigation are provided.

Abstract:

The Internet has become important since information is now stored in digital form and is transported both within and between organisations in large amounts through computer networks. Nevertheless, there are those individuals or groups of people who utilise the Internet to harm other businesses because they can remain relatively anonymous. To prosecute such criminals, forensic practitioners have to follow a well-defined procedure to convict responsible cyber-criminals in a court of law. Log files provide significant digital evidence in computer networks when tracing cyber-criminals. Network log mining is an evolution of typical digital forensics utilising evidence from network devices such as firewalls, switches and routers. Network log mining is a process supported by presiding South African laws such as the Computer Evidence Act, 57 of 1983; the Electronic Communications and Transactions (ECT) Act, 25 of 2002; and the Electronic Communications Act, 36 of 2005. Nevertheless, international laws and regulations supporting network log mining include the Sarbanes-Oxley Act; the Foreign Corrupt Practices Act (FCPA) and the Bribery Act of the USA. A digital forensic model for computer networks focusing on network log mining has been developed based on the literature reviewed and critical thought. The development of the model followed the Design Science methodology. However, this research project argues that there are some important aspects which are not fully addressed by South African presiding legislation supporting digital forensic investigations. With that in mind, this research project proposes some Forensic Investigation Precautions. These precautions were developed as part of the proposed model. The Diffusion of Innovations (DOI) Theory is the framework underpinning the development of the model and how it can be assimilated into the community. The model was sent to IT experts for validation and this provided the qualitative element and the primary data of this research project. From these experts, this study found out that the proposed model is very unique, very comprehensive and has added new knowledge into the field of Information Technology. Also, a paper was written out of this research project.

Abstract:

Data-centric security is significant in understanding, assessing and mitigating the various risks and impacts of sharing information outside corporate boundaries. Information generally leaves corporate boundaries through mobile devices. Mobile devices continue to evolve as multi-functional tools for everyday life, surpassing their initial intended use. This added capability and increasingly extensive use of mobile devices does not come without a degree of risk - hence the need to guard and protect information as it exists beyond the corporate boundaries and throughout its lifecycle. Literature on existing models crafted to protect data, rather than infrastructure in which the data resides, is reviewed. Technologies that organisations have implemented to adopt the data-centric model are studied. A utopian model that takes into account the shortcomings of existing technologies and deficiencies of common theories is proposed. Two sets of qualitative studies are reported; the first is a preliminary online survey to assess the ubiquity of mobile devices and extent of technology adoption towards implementation of data-centric model; and the second comprises of a focus survey and expert interviews pertaining on technologies that organisations have implemented to adopt the data-centric model. The latter study revealed insufficient data at the time of writing for the results to be statistically significant; however; indicative trends supported the assertions documented in the literature review. The question that this research answers is whether or not current technology implementations designed to mitigate risks from mobile devices, actually address business requirements. This research question, answered through these two sets qualitative studies, discovered inconsistencies between the technology implementations and business requirements. The thesis concludes by proposing a realistic model, based on the outcome of the qualitative study, which bridges the gap between the technology implementations and business requirements. Future work which could perhaps be conducted in light of the findings and the comments from this research is also considered.

Abstract:

The phrase 'Internet of Things' refers to the pervasive instrumentation of physical objects with sensors and actuators, and the connection of those sensors and actuators to the Internet. These sensors and actuators are generally based on similar hardware as, and have similar capabilities to, wireless sensor network nodes. However, they operate in a completely different network environment: wireless sensor network nodes all generally belong to a single entity, whereas Internet of Things endpoints can belong to different, even competing, ones. This difference has profound implications for the design of security mechanisms in these environments. Wireless sensor network security is generally focused on defence against attack by external parties. On the Internet of Things, such an insider/outsider distinction is impossible; every entity is both an endpoint for legitimate communications, and a possible source of attack. We argue that that under such conditions, the centralised models that underpin current networking standards and protocols for embedded systems are simply not appropriate, because they require such an insider/outsider distinction. This thesis serves as an exposition in the design of decentralised security mechanisms, applied both to applications, which must perform access control, and networks, which must guarantee communications security. It contains three main contributions. The first is a threat model for Internet of Things networks. The second is BottleCap, a capability-based access control module, and an exemplar of decentralised security architecture at the application layer. The third is StarfishNet, a network-layer protocol for Internet of Things wireless networks, and a similar exemplar of decentralised security architecture at the network layer. Both are evaluated with microbenchmarks on prototype implementations; StarfishNet's association protocol is additionally validated using formal verification in the protocol verification tool Tamarin.

Abstract:

AbstractThe drive for automation and constant monitoring has led to rapid development in the field of Machine Learning (ML). The high accuracy offered by the state-of-the-art ML algorithms like Deep Neural Networks (DNNs) has paved the way for these algorithms to being used even in the emerging safety-critical applications, e.g., autonomous driving and smart healthcare. However, these applications require assurance about the functionality of the underlying systems/algorithms. Therefore, the robustness of these ML algorithms to different reliability and security threats has to be thoroughly studied and mechanisms/methodologies have to be designed which result in increased inherent resilience of these ML algorithms. Since traditional reliability measures like spatial and temporal redundancy are costly, they may not be feasible for DNN-based ML systems which are already super computer and memory intensive. Hence, new robustness methods for ML systems are required. Towards this, in this chapter, we present our analyses illustrating the impact of different reliability and security vulnerabilities on the accuracy of DNNs. We also discuss techniques that can be employed to design ML algorithms such that they are inherently resilient to reliability and security threats. Towards the end, the chapter provides open research challenges and further research opportunities.

Abstract:

The purpose of this chapter is to address the security breaches in cybercafés and also suggest measures of securing the unsecured computers. In order that cybercafés operate breach free Internet services, there is need for measures to be put in place to secure their network. This chapter of the book therefore unveils the security situation in cybercafés with the view to address network security, network breaches, and methods of protecting cybercafés’ systems. The chapter reveals some ways through which cybercafés encountered breaches such as Trojan horse programs, back door and remote administration programs, unauthorized access, denial of service, and so forth, and equally suggests measures of protecting the computers or networks such as installation of firewalls, use of antivirus, avoidance of opening unknown attachments, disabling of hidden filename extensions, keeping all applications parched, disconnecting from the net when not in use, regular backup of data, virtual private networks, and so forth.

Abstract:

The modern network and Internet security vulnerabilities expose state and local government networks to numerous threats such as denial of service (DoS) attacks, computer viruses, unauthorized access, confidentiality breaches, and so forth. For example, in June 2005, the state of Delaware saw a spike of 141,000 instances of “suspicious activity” due to a variant of the mytopb worm, which could have brought the state’s network to its knees had appropriate steps not been taken (Jarrett, 2005; National Association of State Chief Information Officers [NASCIO], 2006b). On an average day, the state of Michigan blocks 22,059 spam e-mails, 21,702 e-mail viruses, 4,239 Web defacements, and six remote computer takeover attempts. Delaware fends off nearly 3,000 attempts at entering the state’s network daily (NASCIO, 2006b). Governments have the obligation to manage their information security risks by securing mission- critical internal resources such as financial records and taxpayer sensitive information on their networks. Consequently, public-sector information security officers are faced with the challenge to contain damage from compromised systems, prevent internally and Internet-launched attacks, provide systems for logging and intrusion detection, and build frameworks for administrators to securely manage government networks (Oxlenhandler, 2003). This chapter discusses some of the cost-effective measures needed to address government agency information security vulnerabilities and related threats.

Abstract:

The purpose of this study was to understand the effects of cybercrime to Zimbabwe's peace and security. In the 21st century, cybercrime has become an international threat. This has necessitated many states to enact legislation and other measures to curb cybercrime. Primary data was gathered through key informant interviews, while documentary search was used to review scholarly literature on the subject. Key informants for the study were drawn from institutions that deal in combating cybercrime. Zimbabwe does not have adequate and effective legislative instruments to combat cybercrime. Cybercrime is a threat to peace and security as it can be used to bring down critical infrastructure and disrupt communication networks of the country. Some of the measures identified to curbing cybercrime include prevention and awareness, training and development, development of new technology and introduction of new laws, and updating of current and introduction of new legislations.

Abstract:

Operations has grown beyond relying only on SCADA infrastructure — can you operate without your non-scada infrastructure? As the operator of the world’s longest and most complex liquids pipeline, Enbridge Pipelines Inc. relies heavily on automated systems to control, monitor, maintain our pipeline system. As the scope of automation continues to expand beyond the SCADA control system, so to does the dependence on ancillary computer applications such as pipeline scheduling, electronic ticketing, nominations and oil accounting. Uninterrupted operation of the pipeline system now depends on an increasingly complex electronic infrastructure and new levels of reliability are required from this infrastructure. This paper will describe the inherent risks as we continue to increase the automation of pipelining functions such as scheduling, oil accounting and electronic ticketing. We will discuss the type of technological threats (system failure, design flaws, security) and the strategies adopted by Enbridge for mitigating each of them. Further to the risks, this paper will explore the infrastructure components where exceptional risk mitigation is required, and the measures that Enbridge has taken to minimize the risks associated with those components. Specific areas to be analysed include; wide and local area networks, power and environmental systems, system clustering, hot and cold standby systems, network segment isolation and system backup solutions. Attention will also be paid to the increasing dependence on shared infrastructure services such as the Internet and telecommunications. For each of these technology areas, we will discuss the level of adoption within Enbridge, and the value proposition for these decisions. We will attempt to answer the questions; Why go that far? Why not go further? Finally, we will discuss the technology infrastructure requirements for business resumption. We will discuss system and site redundancy alternatives employed by Enbridge, the challenges involved in establishing business resumption plans, and how they are used by Enbridge to minimize the operational risk to our pipeline.
