IoT devices already use a CSP’s existing infrastructure for network connectivity, hence CSPs are in a perfect position to serve as gatekeepers. The residential gateway is typically the weakest point of a home network. Yet from a CSP’s perspective, it is the ideal point from which to deploy advanced cybersecurity. A range of advanced and scalable security technologies can be deployed at the network edge to effectively address all the vulnerabilities mentioned above.

Advanced security at the network edge

Automatic device discovery detects all devices on a wi-fi network and assigns them to appropriate security groups, and then tailors specific profiles for each device to enforce security and privacy policies.

The network edge security needs to include a continuous vulnerability scanning, smart firewall, enterprise-grade intrusion detection and prevention, and URL filtering engine securing all devices from malicious activity. This system must be constantly updated by advanced threat detection tailored to identify IoT-related vulnerabilities and threats.

Artificial intelligence delivers intelligent security

Importantly, advanced behavioral analysis based on cutting-edge artificial intelligence and machine learning technology can use sophisticated algorithms for detecting threats, and even regarding already compromised devices.

When anomalies are detected, a cloud-based platform distributes updated policies to all the residential gateways protected by the CSP, ensuring each home network is constantly updated to meet the latest threats.

Cost-effective for CSPs

This approach provides a raft of benefits for CSPs. First of all, it provides an additional subscription-based revenue stream from a large percentage of existing subscribers. This user base is only going to grow as more IoT devices come online. A wide range of manufacturers are certainly pushing in this direction, including Amazon and Google with their smart home hubs and speakers. This alone explicitly acknowledges that IoT is going to be much bigger than it already is.

A 2016 Ericsson mobility report claims that IoT sensors and devices are expected to exceed mobile phones as the largest category of connected devices in 2018, growing at a 23 percent compound annual growth rate (CAGR) from 2015 to 2021. This is close to what we are already witnessing; more IoT devices already connected in 2018 than there are people on the planet (and the year isn't up yet).

But the issue is not just about providing IoT security alone. Security is also a key enabler for IoT adoption when customers understand comprehensive security is available. Further, it doesn’t require huge investment; it’s simply a question of leveraging the residential gateway for value-added services. It also safeguards CSP’s weakest link—that is, CPEs and residential gateways.

CSPs can offer different cybersecurity offerings such as basic, standard, and premium packages. Further, they gain full visibility into customers’ home networks, including device inventory. The insight gained into customers’ device vulnerabilities also provides a raft of information that can be used for targeted marketing.

Managed cybersecurity services increases operational efficiency—such as customer support and customer service—thanks to the increased insight into residential networks and IoT devices in use. This will most certainly strengthen brands, too. Overall, providing this deep level of IoT device security delivers a compelling advantage in a fiercely competitive and saturated market.
