13	Mapping the Attack Surface of Telecommunication Networks from the Public Internet / Kartläggning av Attackytan på Telekommunikationsnätverk från det Offentliga Internet Rathi, Jayshree January 2023 (has links) The telecommunications sector is increasingly connected to the Internet, resulting in an expanded attack surface accessible from the public Internet. This has increased the availability of information such as IP addresses, open ports, and other network details that anyone from the Internet can access. As a result, potential entry points for attackers have increased, making it essential to map the attack surface of telecommunication networks from the public Internet. While previous research has explored various tools and techniques for mapping the attack surface of the Internet of Things (IoT) and Industrial Control Systems (ICS), such techniques have not yet been extended to the telecommunications domain. This thesis aims to comprehensively map the attack surface of telecommunications operators from the public Internet. To achieve this, we conducted a thorough literature review and proposed a methodology for mapping the attack surface explicitly designed for the telecommunications sector. First, we devised a research workflow that outlines the steps involved in the methodology. Second, we developed a Python-based tool to automate the workflow. We used the tool for a particular mobile network operator. It successfully gathered DNS records, IP addresses, exposed ports, services, Autonomous System Numbers (ASN), server versions, and potential vulnerabilities. The collected data provides valuable insights into the network infrastructure of the operator, aiding in the understanding of potential security risks. / Telekommunikationssektorn blir allt mer kopplad till Internet, detta resulterar i en större attackyta som är tillgänglig från det offentliga Internet. Detta har gett en ökad tillgänglighet av information som till exempel IP adresser, öppna portar, och annan nätverksinformation som vem som helst kan få åtkomst till via Internet. På grund av detta, har potentiella ingångar för attacker ökat, detta gör det avgörande att kartlägga attackytan för telekommunikationsnätverk från det offentliga Internet. Medan tidigare forskning har undersökt olika verktyg och tekniker för att kartlägga attackytor för the Internet of Things (IoT) och Industrial Control Systems (ICS), så har sådana tekniker ännu inte sträckt sig till telekommunikationsdomänen. Denna avhandling har som mål att utförligt kartlägga attackytan för telekommunikationsoperatörer från det offentliga Internet. För att uppnå detta, har vi utfört en grundlig litteraturgranskning och föreslagit en metodologi för kartläggning av attackytor specifikt designat för telekommunikationssektorn. Först konstruerade vi ett forskningsarbetsflöde som beskriver stegen involverade i metodologin. Sedan konstruerade vi ett Python-baserat verktyg för att automatisera arbetsflödet. Vi använde verktyget för en särskild mobilnätverksoperatör. Den samlade framgångsrikt in DNS uppgifter, IP adresser, exponerade portar, tjänster, Autonomous System Numbers (ASN), versioner av servrar, och potentiella sårbarheter. Den insamlade informationen ger värdefulla insikter i nätverksinfrastrukturen hos operatören, vilket hjälper till att förstå potentiella säkerhetsrisker Attack Surface Mapping Telecommunication Passive Reconnaissance Mobile Network Operator Public Internet Kartläggning av Attackytan Telekommunikation Passiv Rekon- naissance Mobilnätsoperatör Offentligt Internet Computer and Information Sciences Data- och informationsvetenskap
14	Net Neutrality - Do We Care? : A study regarding Swedish consumers' point-of-view upon Net Neutrality / Nätneutralitet - Vem bryr sig? : En studie rörande svenska konsumenters syn på Nätneutralitet Patriksson, Andreas January 2017 (has links) Net Neutrality implicates that all data being transmitted online is treated equal by Internet Service Providers. In 2016, the public debate regarding Net Neutrality in Sweden started growing as two major Mobile Network Operators were investigated by the Swedish Post and Telecom Authority for violation of European Union Net Neutrality regulations. Several studies have been conducted regarding Net Neutrality, most of them written in a legal, financial or technological perspective. This study takes another direction, aimed at understanding the consumer’s point of view regarding Net Neutrality. This study investigates whether or not consumers are aware of the subject and if so, how they value it. To measure this, an online survey was constructed, containing a total of 12 questions and statements. 77 people participated in the survey and out of these, 10 people participated in qualitative follow-up interviews. The interviews were semi-structured and individually designed according to each participant’s answers in the survey. This was done in order to gain a deeper understanding of the consumer’s reasoning while answering the survey. The results show that consumers lack knowledge regarding Net Neutrality. A major part of the consumers had not heard of the term or did not know the meaning of it, making it hard to determine whether or not the consumers value NN. However, when given a more concrete example of the implications of Internet Traffic Management from ISPs, the participants had a better understanding of what kind of implications NN could have on their Internet usage. They valued the implications of Net Neutrality, even though they did not know the theory of the term itself. The study also revealed that consumers have a big confidence in National Regulatory Authorities when it comes to looking after the openness of the Internet. Therefore, it is likely that National Regulatory Authorities must inform and educate consumers in the matter of Net Neutrality for them to value it and see its long-term implications. / Nätneutralitet innebär kortfattat att all data som skickas över Internet ska behandlas likvärdigt utav Internetleverantörer (ISP). Under 2016 växte debatten kring nätneutralitet i Sverige då två stycken mobiloperatörer utreddes utav Post- och Telestyrelsen. Båda dessa mobiloperatörer lanserade kampanjer till sina kunder som ansågs strida mot EU:s förordning 2015/2120 rörande nätneutralitet. Ett antal studier har redan gjorts på ämnet nätneutralitet, dock har de flesta haft en infallsvinkel där man tittat på juridiska, finansiella eller tekniska perspektiv. Den här studien har en annan infallsvinkel och riktar sig istället mot konsumenters syn på nätneutralitet. Den ämnar undersöka huruvida konsumenter känner till begreppet nätneutralitet och om de gör det, hur värderar de konceptet? För att undersöka detta konstruerades en online-enkät, innehållandes 12 frågor. 77 personer deltog i enkäten och utav dessa så deltog 10 personer i uppföljande, kvalitativa intervjuer. Intervjuerna var semi-strukturerade och individuella med frågor baserade på individens svar i enkäten. Dessa intervjuer var till för att ge en fördjupad förståelse av konsumenternas syn på nätneutralitet och deras resonemang kring svaren under enkäten. Resultaten visar att konsumenter, deltagande i den här studien, har låg kunskap kring nätneutralitet. Majoriteten utav deltagarna hade inte hört termen eller kände inte till dess mening, vilket gjorde det svårt att dra några slutsatser kring huruvida konsumenterna värderar konceptet. Men när konsumenterna fick ett mer konkret exempel på hur Internetleverantörers datahantering påverkar kundernas Internetanvändande så tycktes konsumenterna förstå vilka implikationer nätneutralitet kan ha på deras eget Internetanvändande. De tycktes således värdera innebörden av nätneutralitet, även om de inte förstod teorin kring konceptet. Studien påvisade också att konsumenter har en stor tilltro till vederbörande myndighet, Post- och Telestyrelsen här i Sverige, när det gäller att se efter Internets öppenhet och mångfald. Det är därför troligt att Post- och Telestyrelsen kommer att behöva informera och utbilda konsumenter rörande nätneutralitet för att få konsumenter att se värdet av och de långsiktiga implikationerna utav det.

15	The complex necessity : A qualitative study exploring the current process for grid connection of large-scale onshore wind farms in Sweden Kuhlefelt, Anna January 2020 (has links) Sweden has a goal of having an electricity production solemnly comprising renewable energy sources by the year 2040. To cater for the fulfillment of this goal, more onshore wind power will be needed in Sweden. The wind farm itself has been studied both in terms of its impacts on societal and environmental interests as well as how the Swedish spatial planning system paves the way for more wind power or not. The connection of wind farms to the regional and national transmission grid is far less studied. Therefore, this thesis explores the grid connection process and how it is experienced by the practitioners in terms of wind power developers and network operators. Also, the ways in which the power grid is taken into account when finding a location for a wind farm is studied. This is done by a literature review and a thematic analysis of ten conducted interviews. The grid connection process is presented, along with the four main themes identified by the thematic analysis; Making two long processes parallel, The importance of grid capacity, Dialogue between the developer and the network operator and Proactive consideration of grid connection. The results suggest that the grid connection process, in combination with the wind farm development, is experienced as time-consuming, which gives rise to problems regarding technology development and puts the finalization of the entire project at risk. Consequently, the practitioners want to make the processes more parallel. This is however complicated by the associated risks of not being reassured grid capacity and inflexible permit procedures. Another important result is that the network operators and developers often have different interests to guard, which can complicate the grid connection process further. The available capacity in the grid is crucial when locating a wind farm, but also the economic distance to the point of connection, which in turn depends on several parameters. It is suggested that consideration of the power grid should be more integrated with the spatial planning in Sweden. This can improve the predictability of wind power planning, promote adequate power grid planning and facilitate the Swedish goal of an electricity production only comprised of renewable energy by 2040. / För att genomföra en grön omställning av Europas energisystem väntas mer elproduktion av förnyelsebar energi integreras.

16	An analysis of new functionalities enabled by the second generation of smart meters in Sweden / Analys av nya funktioner möjliggjort av andra generationen smarta mätare i Sverige Drummond, Jose January 2021 (has links) It is commonly agreed among energy experts that smart meters (SMs) are the key component that will facilitate the transition towards the smart grid. Fast-peace innovations in the smart metering infrastructure (AMI) are exposing countless benefits that network operators can obtain when they integrate SMs applications into their daily operations. Following the amendment in 2017, where the Swedish government dictated that all SMs should now include new features such as remote control, higher time resolution for the energy readings and a friendly interface for customers to access their own data; network operators in Sweden are currently replacing their SMs for a new model, also called the second generation of SMs. While the replacement of meters is in progress, many utilities like Hemab are trying to reveal which technical and financial benefits the new generation of SMs will bring to their operations. As a first step, this thesis presents the results of a series of interviews carried out with different network operators in Sweden. It is studied which functionalities have the potential to succeed in the near future, as well as those functionalities that are already being tested or fully implemeneted by some utilities in Sweden. Furthermore, this thesis analyses those obstacles and barriers that utilities encounter when trying to implement new applications using the new SMs. In a second stage, an alarm system for power interruptions and voltage-quality events (e.g., overvoltage and undervoltage) using VisionAir software and OMNIPOWER 3-phase meters is evaluated. The results from the evaluation are divided into three sections: a description of the settings and functionalities of the alarm, the outcomes from the test, and a final discussion of potential applications. This study has revealed that alarm functions, data analytics (including several methods such as load forecasting, customer segmentation and non-technical losses analysis), power quality monitoring, dynamic pricing, and load shedding have the biggest potential to succeed in Sweden in the coming years. Furthermore, it can be stated that the lack of time, prioritization of other projects in the grid and the integration of those new applications into the current system seem to be the main barrier for Swedish utilities nowadays. Regarding the alarm system, it was found that the real benefits for network operators arrive when the information coming from an alarm system is combined with a topology interface of the network and a customer notifications server. Both applications could improve customer satisfaction by significantly reducing outage time and providing customers with real-time and precise information about the problems in the grid.

17	Evaluating the Benefits of Optimal Allocation of Wind Turbines for Distribution Network Operators Siano, P., Mokryani, Geev January 2015 (has links) No / This paper proposes a hybrid optimization method for optimal allocation of wind turbines (WTs) that combines a fast and elitist multiobjective genetic algorithm (MO-GA) and the market-based optimal power flow (OPF) to jointly minimize the total energy losses and maximize the net present value associated with the WT investment over a planning horizon. The method is conceived for distributed-generator-owning distribution network operators to find the optimal numbers and sizes of WTs among different potential combinations. MO-GA is used to select, among all the candidate buses, the optimal sites and sizes of WTs. A nondominated sorting GA II procedure is used for finding multiple Pareto-optimal solutions in a multiobjective optimization problem, while market-based OPF is used to simulate an electricity market session. The effectiveness of the method is demonstrated with an 84-bus 11.4-kV radial distribution system.

18	Legal and regulatory aspects of mobile financial services Perlman, Leon Joseph 11 1900 (has links) The thesis deals with the emergence of bank and non-bank entities that provide a range of unique transaction-based payment services broadly called Mobile Financial Services (MFS) to unbanked, underserved and underbanked persons via mobile phones. Models of MFS from Mobile Network Operators (MNOs), banks, combinations of MNOs and banks, and independent Mobile Financial Services Providers are covered. Provision by non-banks of ‘bank-type’ services via mobile phones has been termed ‘transformational banking’ versus the ‘additive banking’ services from banks. All involve the concept of ‘branchless banking’ whereby ‘cash-in/cash out’ services are provided through ‘agents.’ Funds for MFS payments may available through a Stored Value Product (SVP), particularly through a Stored Value Account SVP variant offered by MNOs where value is stored as a redeemable fiat- or mobile ‘airtime’-based Store of Value. The competitive, legal, technical and regulatory nature of non-bank versus bank MFS models is discussed, in particular the impact of banking, payments, money laundering, telecommunications, e-commerce and consumer protection laws. Whether funding mechanisms for SVPs may amount to deposit-taking such that entities could be engaged in the ‘business of banking’ is discussed. The continued use of ‘deposit’ as the traditional trigger for the ‘business of banking’ is investigated, alongside whether transaction and paymentcentric MFS rises to the ‘business of banking.’ An extensive evaluation of ‘money’ based on the Orthodox and Claim School economic theories is undertaken in relation to SVPs used in MFS, their legal associations and import, and whether they may be deemed ‘money’ in law. Consumer protection for MFS and payments generally through current statute, contract, and payment law and common law condictiones are found to be wanting. Possible regulatory arbitrage in relation to MFS in South African law is discussed. The legal and regulatory regimes in the European Union, Kenya and the United States of America are compared with South Africa. The need for a coordinated payments-specific law that has consumer protections, enables proportional risk-based licensing of new non-bank providers of MFS, and allows for a regulator for retail payments is recommended. The use of trust companies and trust accounts is recommended for protection of user funds. \| vi / Public, Constitutional and International Law / LLD Agents Airtime transfer Airtime -based SOV Allocation of loss Allocation of risk Anti-Money Laundering (AML) Aristotle Australian school Auto-subscription Banks Banks Act Bilateral Juristic Act Bottom of Pyramid Branchless Banking BSD Business of banking Cash-In /Cash out Central Bank Claim school Competition Commission Condictiones Consumer protection Consumer Protection Act (CPA) Contract law Convergence CTF Dedicated Banks Bill Delict Regulatory philosophies Deposits Deposit-taking Directives Dodd-Frank Electronic Commerce (e-commerce) Electronic Funds Transfer (EFT) Electronic money (e-money) Electronic Money Directive (EMD) European Union (EU) FA Mann Fiat Fiat-based SOV FICA Financial inclusion Financial literacy Foley v Hill Hacking ICASA Kenya KYC Legal capacity m-Banking Means of exchange Means of payment MFS MFSP Miller v Race Minors MNO Mobile Banking (m-Banking Mobile Commerce (m-commerce) Mobile Financial Services (MFS) Mobile Financial Service Provider (MFSP) Mobile Financial Services Provide (MFSP) Mobile Network Operator (MNO) Mobile payments Mobile payments (m-Payments) Mobile purse Mobile wallet Money Money Laundering (ML) m-Payments m-pesa National Consumer Commission National Payment System National Payment System Act (NPSA) Non-Banks NPSA Orthodox school Oversight Payment instrument Payments law Pooled accounts Position paper Proportional regulation Prudential Regulation PSD PSPL PSRA Redeemable funds Regulator's dilemma Regulatory capture Remittances (RICA) (South Africa) Security SIM Card SIPS South African Reserve Bank SOV Specie Store of Value (SOV) Stored Value Account (SVA) Subscriber Supervison Systemic risk Telecommunications Transformational banking Trust accounts Unbanked Underserved Underbanked Unit of account United Dominions Trust (UDT) Unjustified enrichment USA Value Added Services (VAS) Wallet WASP WASPA Additive banking Regulatory arbitrage 346.82120680285 Banks and banking, mobile --South Africa
