Establishing efficient, effective, and trustworthy engineering collaboration while protecting intellectual property is vital to maintain organizational competence in today's global business environment. In this paper, a lean information modeling and sharing framework is described to support engineering data security management in a peer-to-peer collaborative environment. It allows for selective and interoperable data sharing with fine-grained access control at both the server and client sides, thus securing different levels of design information dissemination for intellectual property protection purposes. The considerations of time and value-adding activity with roles, policy delegation relation in a distributed context, and fine-grained control at data set level in the model are to adhere to the general least privilege principle in access control. Heterogeneous design data are exchanged selectively through an eXtensible Markup Language common interface, which provides a neutral format to enhance data interoperability and prevents reverse engineering.

Efficient, effective, and trustworthy collaboration in design is vital to maintain organizational competence. Conventional access control methods are too coarse in inter-organizational lean and secure data exchange. In this paper, a Scheduled Role-Based Distributed Data Access Control Model is described to support data security management in a distributed environment. The model allows for fine-grained data access control at both the server and client sides, thus securing different levels of design information dissemination for intellectual property protection purposes. Common interface for heterogeneous data is built based on XML.

Even though weapons and money are considered important factors for running a modern world, at the end of the day, it is all about controlling and exploiting information for political, military, economic, and commercial advantage. The objective of this chapter is to present a basic understanding of the concept of Information Warfare (IW) and the need for relevant strategies to aid its successful implementation. IW is an important topic in this electronic era and within enterprises, security strategies, tools, and processes are essential in order to maintain a competitive advantage against an adversary or group of adversaries. In this chapter, a Survival of the Fittest IW (SFIW) conceptual framework is presented based on the adaptive nature of IW, and a case study is used to discuss its validity.
