KNOTIS Information System
Ľupták, Andrej ; Smrž, Pavel (referee) ; Dytrych, Jaroslav (advisor)
This thesis addresses the problem of managing people, groups of people, resources, and resource permissions in the Unix system managed by the Knowledge Technology Research Group Information System (KNOTIS). The main objective is to effectively combine the use of access lists and groups to manage user access to resources. Based on the properties of the resource and the number of persons with access, the module automatically evaluates which type of permissions is more advantageous for managing permissions to individual resources. The communication between KNOTIS and a server is implemented using the JSON-RPC communication protocol. The content of the communication messages was defined based on specific demands. The result of this thesis is a new group of modules for KNOTIS and the servers managed by it. The modules focus on a new way of communication between the information system and the servers and on how to process the requested changes on the server side, including a more efficient way of managing resource permissions.
