State-Based Security Policy
Enforcement in Component-Based E-Commerce
Universität Dortmund, FB Informatik, LS IV, D-44221 Dortmund
Software component technology supports the cost-effective
development of e-commerce applications but also introduces special
security problems. In particular, a malicious component is a threat
to any application incorporating it. Therefore wrappers are of
interest which control the behavior of components at run-time and
enforce the application's security policies. The wrapper of a
component monitors the component behavior at its interfaces and
checks its compliance with the security behavior constraints of
the component's employment contract. We propose state-based
security policy definitions, report on their suitable design, and
clarify their employment by means of a component-structured
Security policy enforcement, component security, security wrappers.
