The growing complexity of modern network infrastructures and the heterogeneity of firewall and security technologies have made standardization and automation essential for effective cyber defense management. The Open Command and Control (OpenC2) standard, developed by OASIS, defines a unified language for commanding and controlling security components, enabling interoperability between heterogeneous systems through well-defined producer-consumer interactions. The Stateful Packet Filtering (SLPF) profile specifies how OpenC2 commands can be applied to network filtering systems, defining standardized actions, targets, arguments and results for managing firewalls and similar packet filtering technologies. This thesis defines a complete implementation of the OpenC2 Stateful Packet Filtering (SLPF) profile across four representative platforms: iptables, OpenStack Security Groups, Kubernetes Network Policies and Microsoft Azure Network Security Groups.
