Cyber threat information sharing is an imperative process towards achieving collaborative security, but it poses several challenges. One crucial challenge is the plethora of shared threat information. Therefore, there is a need to advance filtering of such information. While the state-of-the-art in filtering relies primarily on keyword- and domain-based searching, these approaches require sizable human involvement and rarely available domain expertise. Recent research revealed the need for harvesting of business information to fill the gap in filtering, albeit it resulted in providing coarse-grained filtering based on the utilization of such information. This paper presents a novel contextualized filtering approach that exploits standardized and multi-level contextual information of business processes. The contextual information describes the conditions under which a given threat information is actionable from an organization perspective. Therefore, it can automate filtering by measuring the equivalence between the context of the shared threat information and the context of the consuming organization. The paper directly contributes to filtering challenge and indirectly to automated customized threat information sharing. Moreover, the paper proposes the architecture of a cyber threat information sharing ecosystem that operates according to the proposed filtering approach and defines the characteristics that are advantageous to filtering approaches. Implementation of the proposed approach can support compliance with the Special Publication 800-150 of the National Institute of Standards and Technology.

The authors of this chapter argue that business processes can be modeled in the same way as collaborative business services, and therefore use an approach developed for such services. They consider business services that are collaborative and crosscutting in nature; several participants may collaborate in a business service to achieve its goal, and a participant may take part in several different business services, playing different roles in each. A framework to support the development and composition of such business services is the main focus of this chapter. The authors use UML collaborations for modeling the structure of roles involved in a business service/process, and activity diagrams for specifying the global behavior performed by the roles. From these models, reusable components realizing the roles can be automatically synthesized, and such components can then be composed together in order to make different systems that meet the requirements of business services.

The definition and the management of business processes are considered a relevant issue to support organizations in their activities. Indeed, in the last few years many organizations have been changing their business processes to keep competitive in the global market. Workflow management is an emerging technology enabling process performance improvement in a cooperative working environment. In particular, a workflow management system (WfMS) enables processes automation through the integration, the coordination, and communication of both human and automatic task of business processes. WfMSs provide a process definition language (PDL) for modeling business processes. A PDL sentence is named process model and is enacted by a component of the WfMS, namely the process engine. The main task of this component is executing the enactment rules and the activities specified in the Process Model. A huge number of PDLs based on several formalisms have been proposed in literature. Recently, some authors suggest exploiting the unified modeling language (UML) proposed by the Object Management Group (OMG, 2002) to model business processes (Aversano, Canfora, De Lucia, & Gallucci, 2002; Di Nitto, Lavazza, Schiavoni, Tracanella, & Trombetta, 2002; Eriksson & Penker, 2000, Jager, Schleicher, & Westfechtel, 1999; Marshall, 2000). UML is a natural choice for representing business processes, as it is a well known notation that can be easily understood and used by any kind of users. In this article, we propose a Web services-based WfMS that lets users manage and enact business processes. The proposed system offers a visual environment based on an extension of UML activity diagrams that allows to graphically design a process model and to visually monitor its enactment. Since UML does not have a well defined operational semantics and is not executable, we had to make the process model executable by appropriately enriching the syntax and semantics of UML activity diagrams. The architecture of the proposed WfMS is based on Web services to manage and enact distributed business processes.

Effective internal control is essential for successful operations and management of shipping companies. For its implementation, the most important task is to determine the objects of internal control, that is, the scope of its application. Internal control, as a management function, is aimed at solving management problems, therefore, in the author's opinion, objects of management and objects of internal control are identical. Based on the analysis of the approaches of various authors to the choice of management objects, the author's approach has been developed, taking into account the interaction of all elements of the management system, the multidimensional and multi-level nature of management process, and branch features of shipping business. A classification of objects of internal control in shipping companies has been developed with the allocation of such objects as resources, business processes, results of functioning, management decisions. The disclosure of the content of these objects shows that internal control covers all levels of the shipping company, including both the managed and the control systems.
