    ABSTRACT: In today's globalized business world, outsourcing, joint ventures, mobile and cross-border collaborations have led to work environments distributed across multiple organizational and geographical boundaries. The new requirements of portability, configurability and interoperability of distributed device networks put forward new challenges and security risks to the system's design and implementation. There are critical demands on highly secured collaborative control environments and security enhancing mechanisms for distributed device control, configuration, monitoring, and interoperation. This paper addresses the collaborative control issues of distributed device networks under open and dynamic environments. The security challenges of authenticity, integrity, confidentiality, and execution safety are considered as primary design constraints. By adopting policy-based network security technologies and XML processing technologies, two new modules of Secure Device Control Gateway and Security Agent are introduced into regular distributed device control networks to provide security and safety enhancing mechanisms. The core architectures, applied mechanisms, and implementation considerations are presented in detail in this paper.

    ABSTRACT: In cooperative design and engineering, work context has dramatic implications when it comes to building understanding and teams, and getting the work done. From an information security perspective, the context of operation for software or hardware can drive the expectations for security, and may indeed determine the levels of security policy that would be required for collaborative operation. There is a place in this domain for proactive, context-based security implementation. This paper describes a context-centric security enforcement system intended for cooperative design and engineering environments that we call: Environment-Aware Security Enforcement (EASE). We describe the application of this approach to an existing client-server, e-manufacturing application.
