5G applications with ultra-high reliability and low latency requirements necessitate the adoption of edge computing solutions in mobile networks. Container orchestration frameworks like Kubernetes (K8s) have further emerged as preferred standard to dynamically deploy on demand end-users third-party companies. Unfortunately, complex networking security concerns been highlighted challenges that impede successful container technology by industry. The challenge is exacerbated (mis-)conceptions...
Telecom vendors have adopted containerization to improve their software for heterogeneous edge-to-cloud networks. Container orchestration platforms face however challenges when adapting the dynamic demands of multi-tenancy, often leading performance and security conflicts between Cluster Administrators (CAs) applications administrators. In this paper, we propose that network constraints should be directly integrated into scheduler. By dynamically determining preferred segments each...
Packaging applications in containers and managing them dynamically using a cluster orchestrator is the de-facto approach for deployment of cloud-native applications. When run inside virtual machines (VMs) to protect infrastructural assets, network policies (NPs) at container layer security groups (SGs) VM provide complementary firewall mechanisms that strengthen defenses against lateral movement attackers. However, least-privilege NPs may not always be consistent with statically defined,...
Support for Ultra-Reliable Low-Latency Communication (URLLC) in 5G networks has made the adoption of edge computing and cloud-native imperative. However, URLLC applications require low-latency security defenses against attackers to maximize resilience without impacting performance. In this PhD project, we explore use standardized network segmentation solutions achieve goal develop zero-cost techniques enforcement verification consistency policies across different system layers stack that is...
Self-Organising Networks (SON) was introduced by the next Generation Mobile (NGMN) in 4G/LTE networks to automate network management and reduce operational costs. However, SON functions (SF) are provided different vendors as black boxes making it harder predict their performance untested environments. Also, deploying many SFs leads conflicting objectives. These conflicts expected be more apparent with tunable parameters future networks. In this article, we propose empowering distributed...
