Countermeasures to threats from agent platform and malicious code check using dynamic policy file

Mobile agents are autonomous programs that can migrate from one computer host to various hosts and resumes its execution in the remote hosts. Mobile agents are mainly used in distributed environments like Grid. Mobile agents are mostly used in e-commerce applications. The main objective of the proposed system helps in identifying and preventing various types of security threats that occurs in the mobile agent environment. The system provides an efficient and reliable attack detection and prevention process which plays a vital role for the reliable working of the mobile agent system. Distributed environments having heterogeneous architecture being geographically distributed and interconnected via unreliable network media are at the risk of various security threats. A distributed environment consists of unreliable resources therefore security mechanisms cannot be ignored and an efficient security framework is needed. These security threats have to be dealt at the right time so as to increase the computational power of the mobile agent environment.
