1. Strengthening mobile networks: The power of zero trust and DPI in Open RAN

   As Open RAN architectures evolve, so do the security vulnerabilities they face. This article looks at the importance of zero trust architectures (ZTA) for Open RAN, discussing how access control requirements in a multi-vendor, virtualized, cloud-based architecture necessitate stricter access control and security. It examines the role of deep packet inspection (DPI) in ZTA implementations in Open RAN, and how DPI’s analytics are used to establish user identities, context, and continuous adaptive trust for today’s mobile networks.

2. Close-up in the cloud: How micro-segmentation benefits from DPI

   Micro-segmentation segregates networks into smaller VLANs or subnets that are accorded their own security functionalities to safeguard cloud applications from laterally moving threats that typically afflict virtual machines and containers in the cloud. The use of DPI in micro-segmentation can greatly aid in securing applications in the cloud or specifically distributed workloads hosted on virtual machines and containers.

3. SASE: Conquering the ever expanding enterprise edge

   Secure Access Service Edge (SASE) is a network architecture that allows enterprises to securely connect remote users and devices to the enterprise-wide area network(WAN). SASE essentially combines ‘network-as-a-service’ with ‘security-as-a-service’ to provide enterprises, especially those with a growing number of edge connections covering branches, mobile workers, remote workers and IoT devices, the means to monitor, manage and secure their enterprise networks and assets. If SASE will be the crucial architecture for securing and managing the ever-expanding enterprise perimeter, deep packet inspection is the logical complement, providing real-time intelligence at every point along the way.

4. VPN and visibility: the paradox of secure networking

   Secure connectivity provided by Virtual Private Networks (VPNs) enables enterprises to keep their users connected to enterprise resources. Real-time insights into VPN traffic help enterprises manage not just their own VPN services, but also third-party VPN traffic traversing their networks. This blog post discusses how deep packet inspection (DPI) delivers these insights and how enterprises can use these insights for enhanced performance and security of their networks.

6. DPI supporting SASE for 5G security

   SASE is a secure gateway at the edge of a network, bundling network and security functions provided on-demand as a cloud service. DPI can augment the capacities of SASE in securing enterprise 5G networks. This article examines the need for highly reliable and seamless authentication of remote users and endpoints at the edge and explains how DPI in SASE provides the real-time traffic visibility and traffic filtering to enable this.

8. Maximizing the potential of ZTNA with deep packet inspection

   In today’s hybrid enterprise environments, zero-trust network access (ZTNA) is becoming increasingly important to improve the end-user experience while ensuring that the network is secured against attacks and malicious activities. This is possible with next-generation DPI software. DPI supports ZTNA in implementing granular, user- and context-aware authentication across different classes of users, devices, clouds and applications. DPI’s ability to identify traffic anomalies can also be used by ZTNA to identify cyberattacks and other threats on enterprise networks.
