SASE in the spotlight as businesses prioritize edge network security

Edge is the concept that moves computing from a centralized model to a decentralized one, away from datacenter consolidation across cloud and infrastructure, applications, and workloads and closer to where data is generated or consumed. According to a new report from AT&T Business, edge network definitions and usage are in a state of flux across industries as organizations search for effective security strategies that address edge-related risks and allow them to explore its opportunities. Secure access service edge (SASE) is on the radar of some businesses seeking to augment traditional security controls, bring the network and security closer together, and allow for broader, more centralized visibility across an edge network attack surface.

Edge use cases differ across industries, cyber risks felt by all

The report showed that while the mechanics of edge network usage differ significantly for businesses across the healthcare, finance, public, manufacturing, retail, and energy sectors, edge cyber risks are being felt by all. The networks chosen for edge use cases included public and private cellular 5G, non-5G cellular such as 4G and LTE, remote office/branch office, cloud, and both industrial and consumer IoT networks.

Private 5G and cloud were cited as the preferred edge network overall, with the former expected to be the leading-edge network environment used to support use cases for the next three years. Almost three-quarters (74%) of companies surveyed said the likelihood of compromise is 4 or 5 (5 being very likely), with retail and energy/utilities having the highest perceived risk across the six industries.

Ransomware was the top cyberthreat concern across all sectors, while attacks against associated cloud workloads, sniffing attacks against user endpoint devices and components, and attacks against servers/data were cited as the most likely attack vectors for the healthcare, finance, and public sectors, respectively. As for manufacturing, retail, and energy/utility companies, attacks against user and endpoint devices and sniffing attacks against the radio access network (RAN) were named as the most likely attacks vectors, respectively.

Edge cybersecurity controls a priority for businesses

AT&T’s report illustrated a clear focus among organizations in investing toward better cybersecurity controls for their maturing edge environments. However, “The decisions about which controls to use where vary and are dependent on several factors, including whether edge is an extension of cloud or on premises, the edge network environment, whether controls are on or in the edge network, familiarity, regulations, and benefit cost,” it read.

SASE was cited as the standout growth engine due to the increasing number of organizations moving to cloud-based solutions and its ability to bring the network and security closer together. “But certain industries may not want to route all of their data through cloud, so on-premises security solutions will continue to exist in areas such as OT,” the report stated.
