Sammanfattning
The architecture of a software system heavily influences the level of security achieved.
However, a perfectly designed architecture does not provide any security if the implementation does not conform to the constraints. Adhering to a defined architecture
is easier said than done as the representation of its design often requires manual
labor to validate the conformance of the implementation. Previous attempts at
solving the issue of creating a representation that allows for automatic conformance
checking has failed to gain adoption, perhaps due to the disparity between models
and code. In this thesis, we present our investigation and extension of the ArchUnit
library to support the validation of security architectural constraints. In contrast
to previously proposed approaches, ArchUnit represents architectural constraints
via rules that can be validated using conventional unit test runners. We compare
our extension of ArchUnit, called SecArchUnit, to both SonarQube and PMD to
distinguish any difference in their ability to detect violations of constrains as well
as their appropriateness of expressing architectural constraints. Our results show
that SecArchUnit was able to detect a wider variety of constraints and provides an
interface more suitable for defining constraints at the architectural level.
