Abstract: Grid Computing has evolved as the new level of distributed system by combining large number of dynamic heterogeneous resources to work as single unit. This helps in utilizing enormous power of large number of computational resources to solve highly computational specific problems. However, the complex nature of grid computing, also brings with it the increase in rate of failures and security attacks which are diffcult to handle manually. In this thesis, an automated model for self-healing and self-protection of grid environment using multi-agents is presented to deal with such failures and security attacks. The major contribution of the thesis is a model called SHAPE. SHAPE stands for self healing and protection environment. Self-healing and self-protection properties of autonomic computing are used to provides a holistic approach for the design and development of SHAPE. This helps grid environment to adapt itself to meet the requirements of fault tolerance and security from attacks without manual intervention. SHAPE is novel idea that provides many features: (a) It is the first initiative that provides the capabilities for both Self-Healing and Self-Protection in one system. (b) In terms of fault handling, it uses both active and proactive approaches to provide the functionalities to deal with hardware, software and network failures for distributed systems. (c) For self-protecting system from attacks, it has intelligence to keep updating the network profile of intrusion detection system (IDS) to provide protection from attacks like Distributed denial of Service (DDoS), Remote to Local (R2L), User to Root (U2R), and Probing attacks. (d) From agent-based component design principle, SHAPE is highly scalable, robust and reliable model. Architecture of SHAPE is based on multi-agent component architec- ture which consists of two broad categories namely self-healing and self-protection. Under self healing, di erent algorithms are proposed for monitoring and handling hardware, network and software failures. For implementing monitors for failure handling, Q-learning based approach has been extended to work in distributed environment with minimal overhead. Another unique feature in self-healing category is hardware driver hardening to reduce the failure rate because of hardware failures. Under self-protection, support vector machine (SVM) has been used to provide intelligence into the grid environment to handle various security attacks. This provides dynamic intrusion detection system which keep on updating based upon attack activity profiling. SHAPE is validated on Grid environment setup using Globus 4.0 within Thapar University campus. Validations are done based upon standard metrics for fault handling and security. Results are published to research community in form of peer-reviewed journal publications.
