Abstract:

<p>Software vulnerabilities in programs and malware deployments have been increasing almost every year since we started measuring them. Information about how to program securely, how malware shall be avoided and technological countermeasures for this are more available than ever. Still, the trend seems to favor the attacker. This thesis tries to visualize the effects of a selection of technological countermeasures that have been proposed by researchers. These countermeasures: non-executable memory, address randomization, system call interception and file integrity monitoring are described alon

En analyse de risques, les arbres d’attaque sont utilisés pour évaluer les menaces sur un système. Les méthodes formelles permettent leur analyse quantitative et leur synthèse, mais les propriétés exprimant la qualité des arbres d’attaque par rapport au système n’ont pas été formalisées. Dans ce document, nous définissons un nouveau cadre formel pour les arbres d’attaque prenant en compte un modèle opérationnel du système, et dotant les arbres d’une sémantique de chemins.

Abstract:

Computer network systems are constantly under attack or have to deal with attack attempts. The first step in any network's ability to fight against intrusive attacks is to be able to detect intrusions when they are occurring. Intrusion Detection Systems (IDS) are therefore vital in any kind of network, just as antivirus is a vital part of a computer system. With the increasing computer network intrusion sophistication and complexity, most of the victim systems are compromised by sophisticated multi-step attacks. In order to provide advanced intrusion detection capability against the multi-step

"Security for medical devices has gained some attractions in the recent years following some well- publicized attacks on individual devices, such as pacemakers and insulin pumps. This has resulted in solutions being proposed for securing these devices, usually in stand-alone mode. Medical devices are however becoming increasingly interconnected and interoperable as a way to improve patient safety, decrease false alarms, and reduce clinician cognitive workload. Given the nature of interoperable medical devices (IMDs), attacks on IMDs can have devastating consequences. This work outlines our eff

Abstract:

Fingerprint identification is becoming increasingly popular as a means of authentication for handheld devices of different kinds. In order to secure such an authentication solution it is common to use a TEE implementation. This thesis examines the possibility of replacing a TEE with a hypervisor-based solution instead, with the intention of keeping the same security features that a TEE can offer. To carry out the evaluation a suitable method is constructed. This method makes use of fault trees to be able to find possible vulnerabilities in both systems, and these vulnerabilities are then docum

Security of systems can be reasoned about using threat models to discover security issues in the system.

碩士<br>東吳大學<br>資訊管理學系<br>105<br>A "Cloud Platform" is resource sharing through Internet access that supports users’ on-demand computing resources based on the service types provided by the Cloud Service Provider (CSP).
