Abstract. Run-time assertion checking is one of the useful techniques for detecting faults, and can be applied during any program execution context, including debugging, testing, and production. In general, however, it is limited to checking state-based properties. We introduce SAGA, a general framework that provides a smooth integration of the specification and the run-time checking of both data-and protocoloriented properties of Java classes and interfaces. We evaluate SAGA, which combines several state of the art tools, by conducting an industrial case study from an eCommerce software company Fredhopper.

“…Many specification-based runtime-monitoring frameworks have been proposed, including four approaches to parametric monitoring: an automaton-based approach [5,7,15,16,18,20,28,34]; a regular expression-and grammar-based approach [1,18,24]; an approach based on temporal logic [6, 8, 9, 18-20, 24, 32, 33, 39, 48-50]; and a rule-based approach [4,6,35].…”

“…polyLarva [17] is an extension of LARVA [15,16] designed for distributed systems, by which a user can control the location of verifiers in the distributed system explicitly. LARVA specifies the properties of monitored systems by sets of automata which can communicate each other through channels.…”

Runtime Verification

Abstract. Most existing specification languages for runtime verification describe the properties of the entire system in a top-down manner, and lack constructs to describe concurrency in the specification directly. CSP E is a runtime-monitoring framework based on Hoare's Communicating Sequential Processes (CSP) that captures concurrency in the specification directly. In this paper, we define the syntax of CSP E and its formal semantics. In comparison to quantified event automata (QEA), as an example, CSP E describes a specification for a concurrent system in a bottom-up manner, whereas QEA lends itself to a top-down manner. We also present an implementation of CSP E , which supports full CSP E without optimization. When comparing its performance to that of QEA, our implementation of CSP E requires slightly more than twice the time required by QEA; we consider this overhead to be acceptable. Finally, we introduce a tool named stracematch, which is developed using CSP E . It monitors system calls in (Mac) OS X and verifies the usage of file descriptors by a monitored process.

“…It was thus decided that we adopt a standard runtime verification tool, Larva [CPS09], to process the data efficiently, using techniques from [CP13,CPA09]. Larva allows for specifications to be written in a guarded command language format, possibly structured using automata -although for the sake of encoding the semantics of our CNL, the guarded command rules sufficed.…”

Abstract. Addressing tax fraud has been taken increasingly seriously, but most attempts to uncover it involve the use of human fraud experts to identify and audit suspicious cases. To identify such cases, they come up with patterns which an IT team then implements to extract matching instances. The process, starting from the communication of the patterns to the developers, the debugging of the implemented code, and the refining of the rules, results in a lengthy and errorprone iterative methodology. In this paper, we present a framework where the fraud expert is empowered to independently design tax fraud patterns through a controlled natural language implemented in GF, enabling immediate feedback reported back to the fraud expert. This allows multiple refinements of the rules until optimised, all within a timely manner. The approach has been evaluated by a number of fraud experts working with the Maltese Inland Revenue Department.
