Transparent Security is an open-source solution for identifying and mitigating distributed denial of service (DDoS) attacks and the devices (e.g., Internet of Things [IoT] sensors) that are the source of those attacks. Transparent Security is enabled through a programmable data plane (e.g., “P4”-based) and uses in-band network telemetry (INT) technology for device identification and mitigation, […]

In 1997, CableLabs released the very first version of Data Over Cable Service Interface Specification (DOCSIS ® technology) that enabled broadband internet service over Hybrid Fiber-Coaxial (HFC) networks.  Ever since, we’ve been making improvements, greatly enhancing network speed, capacity, latency, reliability and security with every new version. Today, cable operators use DOCSIS 3.1 technologies to […]

The broadband industry has historically relied on public-key cryptography to provide secure and strong authentication across access networks and devices. In our environment, one of the most challenging issues—when it comes to cryptography—is to support devices with different capabilities. Some of these devices may or may not be fully (or even partially) upgradeable. This can […]

We’ve all adjusted the ways we work and play and socialize in response to COVID. This has increased awareness that our broadband networks are critical – and they need to be secure. The cable industry has long focused on delivering best-in-class network security and we continue to innovate as we move on towards a 10G […]

In our ever-connected world, we want our devices and gadgets to be always available, independently from where or which access networks we are currently using. There’s a wide variety of Internet of Things (IoT) devices out there, and although they differ in myriad ways – power, data collection capabilities, connectivity – we want them all […]

Are Your Devices up to Speed? Here’s Why It Matters… Nobody likes to wait for an internet page or movie to load, but did you know there are things you can do to improve the speed? Yes YOU. Even if you think you’re not tech savvy, you can easily check your devices to see if […]

One of the pillars of the 10G platform is security. Simplicity, integrity, confidentiality and availability are all different aspects of Cable’s 10G security platform. In this work, we want to talk about the integrity (authentication) enhancements, that have been developing for the next generation of DOCSIS® networks, and how they update the security profiles of […]

You might have heard of False Base Station (FBS), Rogue Base Station (RBS), International Mobile Subscriber Identifier (IMSI) Catcher or Stingray. All four of these terminologies refer to a tool consisting of hardware and software that allow for passive and active attacks against mobile subscribers over radio access networks (RANs). The attacking tool (referred to […]

It’s Cybersecurity Awareness Month—time to study up! Cybersecurity is a complex topic. The engineers who address cybersecurity must not only be security experts; they must also be experts in the technologies they secure. In addition, they have to understand the ways that the technologies they support and use might be vulnerable and open to attack. […]

CableLabs engages with the IoT industry and the broader stakeholder community, including governments, to help drive increased IoT device security.  The rapid proliferation of IoT devices has the potential to transform and enrich our lives and to drive significant productivity gains in the broader economy. However, the lack of sufficient security in a meaningful number […]
