Abstract

Flexible and distributed management systems based on mobile agents have certain advantages over centralized and static management architectures. However, security plays a decisive role in terms of acceptance and applicability of mobile agents. In this paper we analyze the threats and attacks against mobile agent systems used for management purposes. Therefore, general models of mobile agent based management systems are developed. Based on a risk analysis of these models we derive security requirements. In order to satisfy these requirements components and ...

Abstract

components designed with different programming styles. SOMA grants interoperability by closely considering compliance with the OMG CORBA and MASIF standards. SOMA has already shown the feasibility and effectiveness of the approach for the development of flexible and adaptive applications in several areas, particularly in network and systems management. key words: Mobile Agents, Security, Interoperability, CORBA, Network and Systems Management. 1. Introduction Global distributed systems such as the Internet and the Web have proposed a new framework for application development and have ...

Abstract

: Although there are many projects focusing on multi-agent systems, there are only a few focusing on the knowledge sharing. Furthermore, there is no project aiming at knowledge sharing and groupware system with a very large number of actors (i.e., agents or human counterparts). The internet, in general, and electronic commerce, in particular, are examples of such systems. In this project, we introduce a model and devise an implementation for the large scale knowledge sharing using mass entrophy, Bayesian networks, game ...

Abstract

The increasing dimension and heterogeneity of global Web systems make harder their management with tools based on the client/server model. The Mobile Agent technology overcomes the limits of traditional approaches and proposes solutions that are suitable for the management of distributed and heterogeneous Internet-based systems. The paper describes the MAMAS environment and its implementation with a Mobile Agent technology. MAMAS has the goals of monitoring the whole system, introducing dynamic corrective actions and modifying system policies at run-time. MAMAS achieves these ...

Abstract

A secure system for mobile agents written in a real time high-level functional language with processes and message passing, is described. The emphasis for this system is on security with reasonably secure nodes and secure agent communication, something which is often ignored in most agent systems, but crucial for an open agent system. ...

Abstract

Mobile agent technology offers a new computing paradigm in which a software agent can suspend its execution on a host computer, transfer itself to another agent-enabled host on the network, and resume execution on the new host. The use of mobile code has a long history dating back to the use of remote job entry systems in the 1960's. Today's agent incarnations can be characterized in a number of ways ranging from simple distributed objects to highly organized software with embedded ...

Abstract

The lack of an appropriate external data model is one of the reasons for the dearth of effective network management applications. Many network management computations over Management Information Bases (mibs ) cannot be practically accomplished through remote interactions. This paper describes the design of an mib Computations System that supports the dynamic definition of external data models for mibs. The system consists of a View Definition Language (vdl) to specify mib external views and snmp-agent extensions that implement them. vdl views ...

Abstract

Commercial or wide-network deployment of Mobile Agent Systems is not possible without satisfying security architecture. In this paper we propose architecture for secure Mobile Agent Systems, using Trusted Domains and Proxy agents. Existing approaches are based on security services at the level of an agent system, library or specific objects. Our concept uses proxy agents to enable transparent security services both to security-aware mobile agents and legacy agents. Per-agent and domain-level... ...

Abstract

As agent-oriented paradigm is reaching a significant level of acceptance by software developers, there is a lack of integrated high-level abstraction tools for the design and development of agent-based applications. In an effort to mitigate this deficiency, we introduce Agent Academy, an integrated development framework, implemented itself as a multi-agent system, that supports, in a single tool, the design of agent behaviours and reusable agent types, the definition of ontologies, and the... ...
