Nokia today launched its extended detection and response (XDR) software and said AT&T, Dish Network, and T-Mobile Netherlands are customers.
The vendor’s NetGuard XDR Security Operations product provides communications service providers with better protection for their 5G networks, said Gerald Reddig, who leads product marketing for Nokia’s Digital Trust security software portfolio. And it also gives them a way to monetize new security services such as 5G slice monitoring, endpoint protection for enterprise IoT devices, and identity and access management.
Nokia’s XDR platform “is the next evolutionary step from what we launched in late 2019 under the name NetGuard Adaptive Security Operations,” Reddig said. That earlier product suite, dubbed NASO, included security orchestration, automation, and response (SOAR) along with network traffic analysis (NTA) and endpoint detection and response (EDR). “It was, from the beginning, an XDR-driven approach,” he added.
XDR, while a still newish security segment, combines elements of security information and event management (SIEM), SOAR, EDR, and NTA in a cloud-based platform. This centralizes security data, threat hunting, and incident response.
In addition to the existing NASO capabilities, Nokia added new analytics, machine learning, and automation functions to NetGuard XDR. “And we now look into any cloud” to detect and stop threats, Reddig said. This means Nokia’s XDR provides correlated views across the 5G network including endpoint and clouds. “This is the major hop in the XDR release — the cloud-native environment so that we can provide this in any cloud,” Reddig said.
Service providers can choose the XDR platform alone, or a managed detection and response version. This uses Nokia’s XDR capabilities as well as its 24/7 Security Intelligence Operations center to provide managed threat detection and incident repose for security incidents in 5G networks.
Nokia XDR Focuses on Integrations, Monetization
The platform also integrates with existing security tools, including SIEMs. In fact, Nokia’s Security Intelligence Operations uses Splunk as its SIEM and integrates its own XDR with that vendor’s security information and event management capabilities.
Nokia claims that NetGuard XDR provides 70% increased effectiveness at blocking threats, according to customer field-trial data, by integrating tools from multiple vendors, putting previously siloed information into context, and streamlining security automation, analytics, and response actions from across the entire network.
“The two themes we are addressing with NetGuard XDR is integration and monetization,” Reddig said. The integration piece spans security tools and data lakes along with third-party and open source threat intelligence feeds, he added.
“And then finally, it’s the integration of operations,” Reddig said, adding that this integration “ensures that service operations and security operations are not two siloed workflows.”
This also plays into the monetization piece, and this is where XDR provides operators with an opportunity to sell security as a service, Reddig said. “For instance, 5G slice services,” he explained. “5G slicing is one of the key themes right now when we talk with our customers, because it defines the future for 5G.”
However, securing different 5G network slices “is not that easy,” he said, adding that is requires “manual work to pre-describe security parameters for a particular slice. For instance, the automotive slice versus the energy utility slice require different security parameters.”
This is where Nokia’s services and security orchestration come into play and differentiate its XDR approach, Reddig said. “Both software pieces are talking to each other,” he said. “Security orchestration helps the service operation to define what kind of security parameters need to be selected for this particular slice.”
