  This paper proposes a cascading classifier for inspecting and validating the payload of chat messages in (military) instant messaging. The first step in the cascading classifier pipeline is an anomaly detection-based method whose purpose is to ensure that the message channel is not used to exfiltrate non-message data such as images, documents, binary files or encrypted content. Messages that pass the filtering phase then proceed to have their content analyzed for the presence of known sensitive information. This data loss prevention step is enhanced by incorporating an author profile signal that assesses the validity of the claimed authorship by capturing the stylometric signature embedded in each user's past message stream. The hypothesis being that the inference and subsequent inclusion of latent author traits such as gender, age and ethnicity will aid the data loss prevention solution by reducing the number of incorrect classifications. Experiments were conducted using message traffic that was generated during a field-training exercise conducted by members of the armed forces, as well as an internal repository of classified documents and a myriad of non-message based data sources. The results demonstrated that our proposed traffic-filtering classifier is successful in distinguishing between legitimate and illegitimate traffic. Further, the experiments showed that constructing authorship verification models, using sparse messages as a training set, is feasible and that including this signal in the data loss prevention solution leads to a significant increase in the predictive performance for the cross-domain messaging setting.

  Service-oriented architectures (SOA) provide the advantage of facilitating integration and information exchange between different administrative domains (e.g., within a coalition). However, in order to support this in a secure manner, cross-domain access control is required. Various solutions to this have been developed with civilian Internet applications in mind. In this paper we consider the architectural approaches (i.e., communication patterns) used by these existing solutions and find that these approaches are not suitable for use in many military systems due to differing connectivity characteristics and availability requirements. A different approach is therefore proposed in order to better fulfill the availability requirements of military applications. Furthermore, we also consider how such access control solutions can be implemented bearing in mind the assurance requirements of military security mechanisms compared to those of typical civilian applications.
