The data lake collects security data from sources like Amazon VPC Flow Logs and AWS CloudTrail, third-party sources like Splunk, CrowdStrike, Datadog, and Cribl, and their own sources of data. 



Keysight and Nokia test 6G active sub-THz components

Keysight Technologies and Nokia Bell Labs will demonstrate component and radio frequency integrated circuit (RFIC) characterization for 6G subterahertz (sub-THz) radio frequency (RF) applications in the D- and E-bands at the International Microwave Symposium 2023 (IMS 2023) in June.

The companies have been collaborating to develop characterization techniques to test active sub-THz components, such as amplifiers, mixers, and frequency converters, to ensure they do not introduce additional signal distortion into communications systems.

The demonstration characterizes a Nokia power amplifier (PA) developed for use in 6G D-band wireless communications systems and designed to operate with a low error vector magnitude (EVM). Using the Keysight N5290A PNA Millimeter Wave System, Nokia Bell Labs can accurately detect the PA’s low EVM, which is a measure of the signal distortion introduced into the communications system by the component. With these measurements, Nokia Bell Labs can better understand the PA’s performance to optimize its 6G transmission system design.

Keysight and Nokia Bell Labs are also partnering to showcase an E-band test solution at IMS 2023. The demonstration features the Keysight N9042B UXA Signal Analyzer used in combination with the V3050A Signal Analyzer Frequency Extender to measure a Nokia transceiver RFIC designed for use in an E-band system for backhaul applications.

Shahriar Shahramian, Head of RFIC & Packaging Lab, Nokia Bell Labs, said: “At Nokia Bell Labs we continue to push the carrier frequency and complexity of our RFIC, packaging, and module integration. With these advancements we move the frontier of what is possible from 6G wireless and optical communication systems. Consequently, the test and measurement industry plays a vital role to enable the complex characterization demanded from our devices and to reduce our time to market.”

Broadband Forum issues TR-459 Issue 2 spec

The Broadband Forum announced the second issue of Technical Report-459: Multi-Service Disaggregated BNG with CUPS.

"TR-459 Issue 2 includes an additional layer of flexibility to manage subscriber resiliency, simplifying operations and streamlining provisioning and maintenance," said Jonathan Newton, Co-Director of the Access and Transport Architecture Work Area at Broadband Forum from Vodafone.

Any faults that can cause network outages can be navigated around as the new specification enables the brain of the network (known as the Control Plane, responsible for managing interactions with the customer home router) to intelligently determine whether a switchover to a new User Plane is needed. The User Plane carries network traffic and enforces policies such as Quality of Service (QoS).

“The latest release of the TR-459 standard will continue to drive standards-based interoperability between vendors, with Broadband Forum simplifying network transformation and ensuring more agility and flexibility for broadband operators,” said Craig Thomas, Vice President Strategic Marketing and Business Development at Broadband Forum. “Our work on a Multi-Service Disaggregated Broadband Network Gateway (DBNG) continues to make it easier to deliver fixed broadband services quickly to new and existing customers as the industry continues to transition and offers a migration path from legacy infrastructures to a future agile cloud native approach.”

Standardization of the Control and User Plane Separation (CUPS) for a Multi-Service DBNG enables the Control Plane from one vendor to control and manage the User Plane from another vendor. This builds a more diverse supply chain with a greater choice of Control and User Planes from different vendors leveraging the TR-459 standard.

Broadband Forum members showcased the important capabilities enabled by TR-459 Issue 2 as part of the CloudCO Demonstration at Network X 2022. The demo highlighted Subscriber Group Resiliency and switchover, and DBNG-User Plane traffic steering. The network monitored the subscriber traffic SLAs and when the SLAs were not being met, switched the subscribers to the backup DBNG-User Plane. Subscriber Group Resiliency minimizes network outages during any network faults.

Microsoft: China's Volt Typhoon targets US critical infrastructure

Microsoft uncovered stealthy and targeted malicious activity aimed at critical infrastructure in the United States and carried out by Volt Typhoon, a state-sponsored actor based in China.

Microsoft alledges that this Volt Typhoon campaign is pursuing development of capabilities that could disrupt critical communications infrastructure between the United States and Asia region during future crises.

The attack gains initial access to targeted organizations through Internet-facing Fortinet FortiGuard devices. From there, the attacker extracts credentials to an Active Directory account used by the device, and then attempts to authenticate to other devices on the network with those credentials. Volt Typhoon proxies all its network traffic to its targets through compromised SOHO network edge devices (including routers). Microsoft has confirmed that many of the devices, which include those manufactured by ASUS, Cisco, D-Link, NETGEAR, and Zyxel, allow the owner to expose HTTP or SSH management interfaces to the internet.

The National Security Agency (NSA) has also published a Cybersecurity Advisory [PDF] which contains a hunting guide for the tactics, techniques, and procedures (TTPs) of this attack.
