Feature interaction: the security threat from within software systems

Feature interaction: the security threat from within software systems

Security engineering is about protecting assets from harm. The feature interaction problem occurs when the composition of features leads to undesirable system behaviours. Usually, this problem manifests itself as conflicting actions of features on a shared context. Security requirements may be violated by feature interactions creating security vulnerabilities which can potentially be exploited ...

Assessing Software Security Using Threat Models

Integrated smart grid systems security threat model

The smart grid (SG) integrates the power grid and the Information and Communication Technology (ICT) with the aim of achieving more reliable and safe power transmission and distribution to the customers. Integrating the power grid with the ICT exposes the SG to systems security threats and vulnerabilities that could be compromised by malicious users and attackers. This paper presents a SG syste...

Software Security Vulnerabilities Seen As Feature Interactions

The security of software applications is an important domain, and one that mixes formalisms (e.g. when dealing with cryptography and security protocols) with very ad hoc, low level practical solutions. In this paper, we look at a subset of the “security” field: the production of secure, general purpose software from a software engineering viewpoint. We call this simply “software security”. We s...
