In the digital age, cybersecurity is the first line of defense against an ever-expanding and continually evolving array of threats. The increasing sophistication of cyber threats and a deepening dependence on interconnectivity have elevated cybersecurity technologies from a peripheral consideration to a critical priority.

October is Cybersecurity Awareness Month, but safeguarding digital integrity is a year-round commitment for CableLabs. In our Security Lab, we work to identify and mitigate threats to the access network. We proactively develop innovative technologies that make it easier for internet users to protect their digital lives.

Let’s take a look at some of the CableLabs technologies that are enhancing network security and reshaping the way we protect ourselves online.

DOCSIS 4.0 Security

The new DOCSIS® 4.0 protocol is another promising chapter in the successful life of hybrid fiber coax (HFC) networks, and it brings with it notable security enhancements to the broadband community.

It’s important to note that DOCSIS 4.0 cable modems (CMs) are compatible with existing DOCSIS 3.1 networks. This allows the CMs to take advantage of higher speed tiers even without needing to upgrade the network at the same time. To fully leverage the new upstream bandwidth efficiency and security features of the protocol, both modems and cable modem termination systems (CMTSs) need to support DOCSIS 4.0 technology.

Another key security-enhancing element of the technology is that DOCSIS 4.0 networks come with upgradable security. The technology continues to support the Baseline Privacy protocol (BPI+ V1) used in DOCSIS 3.1 specifications. It also integrates the new version that can be enabled as needed (BPI+ V2).

The new version introduces mutual authentication between devices and the network, eliminates the dependency on the Rivest Shamir Adleman (RSA) algorithm and implements modern key exchange mechanisms. This change enhances device authentications with Perfect Forward Secrecy and cryptographic agility and aligns DOCSIS key exchange mechanisms with the latest Transport Layer Security (TLS) protocol, v1.3.

Further upgrades include enhanced revocation-checking capabilities with support for both Online Certificate Status Protocol (OCSP) and Certificate Revocation List (CRL) in DOCSIS 4.0 certificates. DOCSIS 4.0 also introduces standardized interfaces for managing edge device access (SSH) aimed at limiting the exposure of corporate secrets (e.g., technicians’ passwords) and incorporates a Trust on First Use (TOFU) approach for downgrade protection across BPI+ versions.

Ultimately, the new DOCSIS 4.0 security is designed to provide several options for network risk management. These features include new speeds and capabilities that can be utilized alongside today’s security properties and procedures (e.g., BPI+V1 with DOCSIS 3.1 or DOCSIS 4.0 CMTSs) and advanced protections when needed.

Matter Device Onboarding

Passwords are meant to be secret, so why are users sharing them with all of their Internet of Things (IoT) devices? At CableLabs, we’re working to make it easy for end-users to add devices to their home networks without needing to share a password with every device.

Because so many devices are communicating with one another, standardization is critical — especially when it comes to security. That’s where Matter comes in. The open-source connectivity standard is designed to enable seamless and secure connectivity among the devices in users’ smart home platforms.

Our vision is for each device to have its own credential to get on the Wi-Fi network. The access point (AP) would use this unique credential to grant the device access to the network, and the device then would verify the AP’s credential. This has three incredibly significant advantages for subscribers:

1. It vastly increases the security of the home network. This is because a compromised device cannot divulge a global network password and lead to a compromise of the entire network.

2. It’s possible to leverage the device attestation certificate that comes with every Matter device to inform the network that it’s a verified and certified device.

3. There's no need to reset every single device on the network if the Wi-Fi password is changed.

Join us for a demonstration of Matter at SCTE® Cable-Tec Expo®, which is October 17–19 in Denver, Colorado. Come see us in CableLabs’ booth 2201 to see the future of networked IoT devices and how scanning a QR code can get a device on a network with its own unique credential.

CableLabs Custom Connectivity for MDUs

One of the fastest-growing market segments for broadband providers worldwide is the multi-dwelling unit (MDU) segment. The opportunities here include fast-growing apartment communities, as well as segments such as emergency/temporary housing, low-cost housing, the hospitality and short-term rental markets, and even emergency services.

A common theme across these is the need for an alternate deployment model that allows on-demand service activation and life-cycle management, as well as custom connectivity to various devices. The traditional deployment model of installing customer premises equipment (CPE) on a per-subscriber and/or per-unit basis has hindered operators in delivering services to these segments in a cost-effective manner.

The CableLabs Custom Connectivity architecture is designed to address these constraints by providing dynamic, on-demand subscription activation and device-level management to consumers across the operator’s footprint — without the need to deploy a CPE. The architecture leverages the security controls and mechanisms designed within the CableLabs Micronets technology to provide dynamic, micro-segmentation-based subscription delivery where a subscriber’s devices can connect to their “home subscription” from anywhere on the network and across different access technologies (Wi-Fi, cellular, etc.).

Additionally, it provides consistent operational interfaces for device authentication and service provisioning, as well as billing and subscription management interfaces to enable on-the-fly subscription activation and management.

Safer Networks, Empowered Users

The importance of proactive cybersecurity measures can’t be overstated, and these cutting-edge technologies are proof of CableLabs’ ongoing commitment to enhancing network security. These innovations not only make our networks safer, but they also empower users to take charge of their own online security.

By staying at the forefront of cybersecurity advancements, CableLabs continues to ensure we can all navigate the digital world with greater confidence and peace of mind.

Billions of Internet of Things (IoT) devices have been added to the internet over the past several years. During that time, millions of insecure IoT devices have contributed to massive Distributed Denial of Services (DDoS) attacks, exposing end users’ private data. To address the problem of insecure IoT devices, CableLabs participates in and contributes to several industry standards development organizations with the goal of building security into the very foundation of new devices and IoT protocols. This work culminates in the release of Matter 1.0, a secure interoperable IoT specification that major industry players are rapidly adopting.

Secure IoT Onboarding

The next critical challenge in enhancing IoT security is to extend interoperability between devices and the networks that connect them. Smart-home networks must be able to facilitate the addition of new devices, validate devices that are connected, help ensure that those devices are fully patched and updated, and safely isolate them if they’re vulnerable.

The next generation of smart-home networking begins with connecting the devices securely the first time. It’s no longer sufficient or secure to ask that consumers share their Wi-Fi password with every device on their smart home network. The network must be smart enough to give each device its own credentials to connect to the network. Crucially, the process for adding (also called onboarding) a device to the smart home network must be simple, seamless and secure.

Industry and Government Collaboration

To address this challenge, CableLabs has joined the National Cybersecurity Center of Excellence (NCCoE) Trusted Device Network-Layer and Lifecycle Management. CableLabs and 10 other companies have been collaborating to develop a reliable network-layer onboarding solution for all IoT devices. This solution leverages established non-proprietary standards and protocols, offering secure onboarding while providing device identification, authentication and authorization. This project covers the following objectives:

  • Provide the device with unique network credentials that can be updated securely and automatically, allowing the network to authenticate the device and eliminating the need for a shared password across all IoT devices.
  • Employ a secure network-layer protocol to facilitate the secure and automatic provisioning of devices with both network and application-layer credentials for connecting with other devices and the cloud.
  • Demonstrate successful interoperability between devices built and configured by participating industry collaborators.

Streamlining the User Experience

CableLabs’ contributions to the Trusted Device Network-Layer and Lifecycle Management project harness the simplicity of Wi-Fi Easy Connect from the Wi-Fi Alliance, the secure interoperability of IoTivity from Open Connectivity Foundation and the powerful technology behind CableLabs’ Micronets to create a secure and streamlined process that allows users to onboard, provision and secure devices on their smart-home networks in a single intuitive step.

CableLabs’ involvement in the Trusted Device Network-Layer and Lifecycle Management project underscores its commitment to advancing IoT security and developing best practices for secure and effortless device onboarding. By collaborating with other industry leaders, CableLabs aims to promote the adoption of secure IoT technologies and ensure that consumers have access to reliable and user-friendly solutions for managing their connected devices.

With Great Bandwidth Comes Great Responsibility

With Great Bandwidth, Comes Great Responsibility.

Cable's next generation, 10G networks, holds the promise to deliver symmetrical multi-gigabit speeds that are 100 times faster than what some consumers are currently experiencing today. This great leap forward will enable services and experiences that will drive internet innovation for years to come. It is our mutual responsibility to assure that devices we connect to these blazing 10 gigabit internet connections, are updated and patched, free from default passwords and use proper authentication and authorization.

The lack of following basic cyber-security principals surfaced in the late Fall of 2016, when many popular sites such as Twitter, Amazon, Reddit and Netflix, were unreachable for several periods, lasting hours. The cause was a massive distributed denial of service (DDoS) attack coming from hundreds of thousands of compromised internet of things (IoT) devices. Traffic from these devices overwhelmed the DNS service provider dyn.com and effectively blocked customers and users from reaching these popular Internet locations for hours at a time.

As we approach a world where households are connected at gigabit and greater speeds, building secure devices and getting them in the hands of consumers is essential. Over the last several years CableLabs has been engaged with standard organizations such as, the Consumer Technology Association (CTA) and the Open Connectivity Foundation (OCF), to draft specifications and guide security baselines for IoT devices. This work has culminated in the release of OCF's international ISO\IEC specification for IoT interoperability.

The OCF specification brings together over 450 member companies and work that spans half a decade to apply cyber-security best practices to the IoT. This specification, combined with an open source reference implementation, seven approved global testing and certification labs and an active community of practitioners and member companies (from device vendors, network device venders and network operators), is uniquely positioned to be the secure standard that unites the industry.

With the OCF specification a consumer can buy a certified device from Vendor A and be confident in the knowledge that not only will it work with their certified appliance from Vender B, but it will do so in a way that is encrypted and authenticated. OCF can work with many cloud services but does not inherently need the cloud, promising consumers a good balance between the convenience of the cloud and the privacy and availability of their local networks.

The OCF specification's security-first approach brings it into close alignment with several of the security guidelines from government and industry, including:
