Abstract: The purpose of grid is to allow user to exploit remote resources for data generation, storage and processing. In order to overcome an increased security problem due to the growth of the system size, Globus Security Infrastructure (GSI) comes with security capabilities using Certification Authority (CA). However, this approach bring another security problem because some of the services in Globus such as job management service – Grid Resources Allocation and Management (GRAM) and remote access to data service – Global Access to Secondary Storage (GASS) require firewall to open numerous of ports for the incoming connections. The focuses of this study is to analyze Globus services, which contain GSI, GRAM and GASS and its implementation of port knocking concept. The first part of the research is start with creating the environment of grid computing and cluster development by using the ROCKS operating system. Next, the middleware that uses within the grid computing which called Globus is install. Finally, the third and fourth parts are the port knocking method that is implemented as dynamic firewall application. From the research it can be concluded that the combination of the port knocking and Globus grid cluster help to enhance the security within the grid environment.
