Sammanfattning : This thesis presents an innovative approach to implementing a security enforcement mechanism in the contexts of untrusted software systems, where a piece of code in a base system may come from an untrusted third party. The key point of the approach is that it is lightweight in the sense that it does not need an additional policy language or extra tool. LÄS MER
Sammanfattning : This thesis studies an alternative implementation of asecurity reference monitor in the contexts of extensible and opensystems. A security reference monitor is a classic approach to imposing asecurity policy on an otherwise untrusted system by using a trusted componentwhich intercepts security-relevant resource requests and applies a securitypolicy to decide whether to grant such requests.

Sammanfattning : The times when malware was mostly written by curious teenagers are long gone. Nowadays, threats come from criminals, competitors, and government agencies. Some of them are very skilled and very targeted in their attacks. LÄS MER
Sammanfattning : Software networking promises a more flexible network infrastructure, poised to leverage the computational power available in datacenters. Virtual Net- work Functions (VNF) can now run on commodity hardware in datacenters instead of using specialized equipment disposed along the network path. LÄS MER
Sammanfattning : Reference monitor inlining is a technique for enforcing security policies by injecting security checks into the untrusted software in a style similar to aspect-oriented programming. The intention is that the injected code enforces compliance with the policy (security), without adding behavior (conservativity) or affecting existing policy compliant behavior (transparency). LÄS MER
