Poster: CERIAS Symposium 2014
In a service-oriented architecture (SOA) environment, a service can dynamically select and invoke any service from a group of services to offload part of its functionality. This is very useful to build large systems with existing services and dynamically add services to support new features. One of the main problems with such a system is that, it is very difficult to trust the service interaction lifecycle and assume that the services behave as expected and respect the system policies. We propose a centralized service monitor, that audits and detects malicious activity or compromised services by analyzing information collected via monitoring agents. The service monitor includes two modes of operation - active and passive - where one can evaluate service topologies with various policies.
