What is Edge Cybersecurity?
Edge cybersecurity is the protection of edge networks and devices that are decentralized from the data center, where data is more vulnerable to cyber threats. Edge networks feature many edge computing devices, including mobile phones, clouds, and smaller data centers, each requiring its own digital defenses.
What does edge computing do for cybersecurity?
The emergence of edge computing creates exciting opportunities for connectivity and data collection, offering faster, real-time processing and analysis with less latency. By design, edge computing requires an exponential amount of Internet-connected devices located near the point of data collection. And since not all processing occurs at the edge—some data is still processed at a centralized data center many miles away—a company’s virtual attack surface increases, creating more individual entry points for threats to access sensitive information and mission-critical applications.
A wider, distributed attack surface creates problems for cybersecurity experts, having to protect multiple endpoints and individual devices/components, as well as maintain access to important resources throughout the enterprise without limiting overall performance. Often, cybersecurity experts and IT teams lack the visibility to oversee edge networks effectively.
What is security services edge?
Security services edge (SSE) is a comprehensive collection of cloud-based cybersecurity tools that include elements of zero trust architecture (ZTA), software as a service (SaaS), firewall as a service (FWaaS), and more. Together, these services provide increased visibility and oversight, threat identification and monitoring, cloud security, and multilayered data protection, effectively merging software-defined wide area network (SD-WAN) with network security.
This third-party service incorporates several aspects of the Secure Access Service Edge (SASE) model, a series of cybersecurity best practices for companies to follow for data in transit and data encryption. SASE lets companies reliably transfer networking and security to cloud networks and keep those capabilities secure. These best practices are especially helpful in an era of hybrid and remote work—even before the COVID-19 pandemic—helping facilitate workforce access to resources from virtually anywhere without limiting performance.
HPE and edge cybersecurity
HPE offers both edge and edge cybersecurity solutions for enterprises, helping companies protect their edge networks and excel in a post-perimeter world.
For example, the Aruba 360 Secure Fabric is an enterprise security framework that gives security and IT teams an integrated way to gain visibility, control, and advanced threat defense through an analytics-ready secure infrastructure, securing the physical network infrastructure and the traffic that flows through it. Secure Fabric is embedded in the foundation of all Aruba indoor and outdoor wireless access points (APs), switches, gateways, and controllers.
Pensando Distributed Services Platform for HPE Servers delivers a powerful suite of software-defined network and security services like firewall, micro-segmentation, and telemetry—boosting network performance by moving these services to their ideal location, the server edge, where the transition between network and server occurs. This approach eliminates the need for discrete appliances, simplifies infrastructure design/operations, strengthens security posture, and improves total cost of ownership (TCO) while providing unmatched telemetry, I/O visibility, and troubleshooting insights.
