Abstract:

Récemment, le 3GPP (3rd Generation Partnership Project) a standardisé les systèmes LTE/LTE-A (Long Term Evolution/LTE-Advanced) qui ont été approuvés par l'UIT (Union Internationale des Télécommunications) comme des réseaux de télécommunications mobiles de 4éme génération. La sécurité est l'une des questions essentielles qui doivent être traitées avec soin pour protéger les informations de l'opérateur et des utilisateurs. Aussi, le 3GPP a normalisé plusieurs algorithmes et protocoles afin de sécuriser les communications entre les différentes entités du réseau. Cependant, l'augmentation du nive

Abstract:

Modern cellular networks including LTE (Long Term Evolution) and the evolving LTE- Advanced provide high-speed and high-capacity data services for mobile users. As we become more reliant on wireless connectivity, the security of voice and data transmissions on the network becomes increasingly important. While the LTE network standards provide strict security guidelines, these requirements may not be completely followed when LTE networks are deployed in practice. This project provides a method for improving the security of LTE networks by 1) characterizing a gap between security requirements de

Abstract:

Security protocols are ubiquitously used in various applications with the intention to ensure secure and private communication. To achieve this goal, a mechanism offering reliable and systematic protocol verification is needed. Accordingly, a major interest in academic research on formal methods for protocol analysis has been apparent for the last two decades. Such methods formalize the operational semantics of a protocol, laying the base for protocol verification with automatic model checking tools. So far, little work in this field has focused on protocol standardization. Within this thesis

Abstract:

High data rates and interoperability of vender devices have made WiMAX a prime desire for use worldwide. WiMAX is based on the IEEE 802.16 standard. IEEE 802.16a, b, c & d versions were updated within three years of the first launch of WiMAX. However, during those early years reports were published that highlighted the security weaknesses of the standard. These weaknesses prompted the IEEE to issue a new version, 802.16e to tackle the security issues. Despite this security enhancement, WiMAX remains vulnerable. This research project looks at the vulnerability of WiMAX 802.16e Subscriber Statio

In modern society, security has become an increasingly important subject, as technologyhas become an integrated part of everyday life. The security of a system can be tested withthe help of fuzzing, where incoming messages to the system are altered.

Abstract:

Formal support in the design and implementation of security-aware applications increases the assurance in the final artifact. Formal methods techniques work by setting a model that unambiguously defines attacker capabilities, protocol parties behavior, and expected security properties. Rigorous reasoning can be done on the model about the interaction of the external attacker with the protocol parties, assessing whether the security properties hold or not. Unfortunately, formal verification requires a high level of expertise to be used properly and, in complex systems, the model analysis r

The surge of mobile devices, such as smartphones, and tables, demands additional capacity.

Additionally, some use cases, such as automated manufacturing process, automated transportation, and smart grid, require latency as low as 1 ms, and reliability as high as 99.99\%. To enhance throughput and support massive connectivity, sharing of the unlicensed spectrum (3.5 GHz, 5GHz, and mmWave) is a potential solution. On the other hand,

5G telecommunication systems must be ultra-reliable to meet the needs of the next evolution in communication. The systems deployed must be thoroughly tested and must conform to their standards.

With fuzzing, testers can send crafted inputs to monitor the System Under Test (SUT) for a response. 3GPP, the standardization body for the telecom system, produces new versions of specifications as part of continuously evolving features and enhancements.

Organizations have many employees that lack the technical knowledge to securely operate their machines. These users may open malicious email attachments/links or install unverified software such as P2P programs. These actions introduce significant risk to an organization's network since they allow attackers to exploit the trust and access given to a client machine. However, system administrators currently lack the control of client machines needed to prevent these security risks. A possible solution to address this issue lies in attestation.

Abstract:

De nos jours, l’e-commerce est devenu un écosystème complexe où de multiples solutions (en termes de plateforme) sont possibles et réalisables pour un e-commerçant. En parallèle, un nouveau paradigme a fait son apparition, celui du Cloud Computing. Malgré les avantages certains qu’il apporte, peu des plateformes existantes sont pensées pour fonctionner sur une architecture Cloud. De plus, face à la complexité d’obtenir une plateforme d’e-commerce (PE) sécurisée, flexible et évolutive s’appuyant sur des applications et services hétérogènes existants et répondant aux besoins des e-commerçants, i

The tendency after the end of the Cold war to downsize national armies on the one hand and persistent armed conflicts in unstable African, Near East and Balkan regions on the other created opening conditions for the revival and rapid evolvement of the private business structures that provide military and security services. Prevailing viewpoint that PMSCs and their personnel represent the new form of the mercenary is not correct from the IHL perspective and could lead to serious human rights abuses.

Abstract:

Internete galima rasti nemažai svetainių, kurios yra sukurtos naudojantis viena iš daugelio šiuo metu prieinamų žiniatinklio turinio valdymo sistemų (TVS). TVS paprastai nereikalauja išsamių techninių žinių, jos ir kuriamos su idėja, kad bet kuris naudotojas galėtų nesunkiai sukurti ir paskelbti savo interneto svetainę. Deja, eiliniai TVS naudotojai dažnai turi nedaug žinių informacijos saugumo srityje. Turinio valdymo sistemų pagrindu sukurtoms svetainėms, kaip ir nuo pagrindų suprogramuotiems tinklalapiams, kyla panašios bendrosios su saugumu susiję grėsmės. Tačiau be bendrųjų grėsmių dar eg

Each solution component provides security capabilities designed to meet its own requirements. However, it is not enough to look at security purely from the perspective of individual components. To provide security for the overall solution you must also consider how the components interact. This paper describes the common characteristics of .NET Web applications from a security perspective.

Šios programos leidžia vartotojams įvesti informaciją ir ją įvedus formuojamos SQL užklausos, kurios siunčiamos į duomenų bazės serverį. Darydamas SQL injekcijos ataką, atakuotojas per įvesties laukus suformuoja kenksmingą SQL užklausos segmentą, kuris modifikuoja buvusią užklausą. Naudodamas SQL injekcijos ataką, atakuotojas gali prieiti prie konfidencialios informacijos, ją modifikuoti ar, apeidamas autorizacijos scenarijų, prisijungti prie sistemos nežinodamas slaptažodžio.
