Security for Vertical Industries

Abstract

Having a changing ecosystem in 5G requires coordinating and adapting new security capabilities for Mobile Virtual Network Operators (MVNOs) that can cover several verticals, their new business models, and mode of operation. In such an ecosystem, cloud service providers should offer corresponding security services to MNVOs, regarding the deployment, layer, and configuration of security functions. Furthermore, 5G network slicing requires automated security and orchestration functionality, especially in complex network environments comprising multiple providers and multiple tenants. MNVOs must not only define security‐related Service Level Agreements (SLAs) for new business models but also offer automated security management capabilities to tenants like verticals. To utilize such benefits and toward a secure and flexible 5G architecture, this article investigates MVNOs' security challenges and mitigation mechanisms for cloud layers as well cloud deployments. In addition, in this article the challenges for MVNOs to correlate security events in 5G scenarios are analyzed and a framework for automated security event management is proposed to offer security monitoring and correlation capabilities to mobile network operators, infrastructure service providers, and tenants like verticals.

Verticals in 5G MEC-Use Cases and Security Challenges

“…On the other hand, several papers consider specific security models and approach helpful in this topic. For instance, the paper [29] investigates mobile network operators' security challenges and mitigation mechanisms for cloud layers as well cloud deployments. The chapter [30] provides an overview of different IoT-based verticals, associated security requirements, threats, and possible mitigations.…”
