How IoT is Revolutionizing Cybersecurity and Why Edge Identity Security Matters
Here I am at my desk after my third coffee of the day (I know, it’s excessive), and I’m thinking about how the Internet of Things (IoT) has changed the cybersecurity game — and why edge identity security has never been more important. From when I began my career as a network admin in ’93 and we were more concerned with voice and data muxing over PSTN and worrying about smart fridges phoning home, it’s been a wild ride. I still have the image burned into my brain of the Slammer worm grinding networks to a halt in minutes — the way I see it, IoT devices are our new attack surface that we need to secure in an airtight fashion.
IoT Threat Landscape
That is the beauty of IoT security: Unlike traditional endpoints, IoT devices are largely forgotten. They are everywhere — factories, hospitals, retail, banks — and each is a potential attack vector. Bad people know devices like these do not commonly have good authentication and are infrequently updated. A lot of times they are running firmware into oblivion.
The complexity is staggering:
- Billions of devices connected running variety of protocols
- Limited CPU, so traditional security software wasn’t going to work
- Devices forklifted by vendors targeting deployment rather than security
- An extended attack surface that is difficult to enumerate or control
In my recent work helping three large banks update their zero-trust architecture, hunting for every one of those IoT endpoints was as easy as herding cats. No joke. What was a huge benefit to us was the very methodical way we approached finding assets — a thing PJ Networks is proud of. You can’t guard what you don’t know is out there.
FortiAuthenticator’s Role
At PJ Networks – for our identity management for IoT, we believe in FortiAuthenticator. In fact this beast is no ordinary AAA server, it plays extremely well with FortiGate and the wider Fortinet Fabric ecosystem, providing centralised authentication, dynamic user identity and single sign-on (SSO).
Here’s why it stands out:
- Strong device identification and on-boarding: FortiAuthenticator is able then to not only automatically discover IoT devices present on your network, and the use of strict policies at the time they enter.
- Flexible auth method: Did they switch to 802.1x but can’t get their mac-dot1x config to work? Does your security guy think they can only authenticate with certificates? Does smokeshop1937214.com want to authenticate by wpa-psk, but only between 5am and 5:30am since that’s the slower time? It doesn’t care, it fits in all those situations; brash best-by audits really grind user gears, but letme-guess, to machines, thx to you, there’s noplace they’d rather be than still in your netbaby.
- Automation for policy enforcement: It takes identity data straight into FortiGate firewall, helps dynamic segmentation, a must-have in a zero-trust model.
Real talk: I’m reminded of a deployment where there was a runaway IoT lighting controller blasting traffic across the network. We were able to quarantine it immediately with FortiAuthenticator. Without that edge identity context, it very well might have gone unchecked until it did actual harm.
FortiAP Deployment
FortiAPs are more than just pretty access points, they are your IoT gateway. I have been on networks where IoT devices get on however and nothing is in the way and no one knows. By deploying FortiAPs, you guarantee that your wireless infrastructure will be securely anchored in the Fortinet Fabric.
Why FortiAP?
- It supports device profiling, which means that you can determine not just a MAC address but a device type, OS, and vulnerability status.
- Integration with FortiGate allows you to have real-time threat intelligence applied to each connected device.
- Includes native wireless segmentation, with IoT devices segmented off sensitive networks.
Just last month, fresh off the plane from DEFCON’s hardware hacking village (still in awe of it), I had put together FortiAP tech when a client in manufacturing had been looking for an IoT security upgrade. If you believe IoT is safe except for the wireless entry point, all I can say is you are begging for trouble.
Integration Steps
The real magic is in integrating FortiAuthenticator and FortiAP with FortiGate for centralized enforcement. Here’s the straight (and sneezed-and-coughed) skinny from my actual field deploys:
- Asset Discovery & Profiling You can utilize FortiAuthenticator’s network access control (NAC) to discover IoT devices as they join the network. At PJ Networks we never set policies until we have properly completed asset inventory.
- Set up authentication policies: Control who can connect to ensure only trusted devices are allowed with strict 802.1X or certificate-based authentication through FortiAuthenticator.
- Deploy FortiAPs for Wireless Access: Deploy FortiAPs with enabled device profiling, and tag IoT devices for classification.
- Implement Segmentation Policies in FortiGate: Where FortiGate leverages identity feeds to enforce network segmentation which reduces the risks of lateral movement.
- Monitoring & Firmware Updates: PJ Networks does not leave you hanging after deployment. Continuous NOC surveillance and proactive updates of firmware for each and every element are necessary. (If you think your gadgets are set and forget, you’re dreaming.)
And I’ll just add this: No integration is ever complete without ongoing supervision. The bad guys are moving targets, and we need to be too.
PJ Networks Support
Why choose us? But since big picture is what we do different. We’ve been around long enough — indeed, long enough to burn our fingers on plenty of mistakes (including one epic ransomware recovery right at the beginning). Please consider subscribing today to support stories like this one. Today, everything is part of a whole at PJ Networks:
- IoT assets discovery and management from end to end
- Customized security configuration services for any vendor platform
- NOC real time monitoring to see anomalies in real time
- Controlled firmware update cycles, so vulnerabilities get zapped quickly
Our most recent zero-trust upgrades for banking customers required us to shoehorn thousands of end points — from hundreds of IoT devices to hundreds of actual endpoint devices — into closely meshed identity and access frameworks without business interruptions. It’s not just about tech—it’s about experience.
ROI Analysis
Look, I get it. IoT security sounds costly — why spend so much on what are essentially networked light bulbs and printers? But the ROI is real:
- Reduced breach risk. One of your compromised IoT devices can be the backdoor to your crown jewels.
- Operational uptime. The fewer the attacks the less downtime, so you end up saving the real moolah.
- Regulatory compliance. Increasing number of industries implementing rigorous IoT security measures.
- Simplified management. Not for administratively overhead the admin overhead toward a more centralised identity and access.
Similarly, one customer said they had reduced their incident response times by 40% after deploying FortiAuthenticator and FortiAP with FortiGate. And they got peace of mind — so let’s not put a price on that.
Quick Take
- IoT security is no longer a checkbox – it’s foundational.
- FortiAuthenticator acts as the identity glue for all of your IoT devices in your environment.
- FortiAPs protect the wireless network, which is essential for controlling IoT devices.
- FortiGate integration for dynamic network segmentation and policy enforcement.
- Discovery, configuration, monitoring, and updates are made easy through PJ Networks rich experiences.
- Without continuous monitoring, your IoT network will explode.
Final Thought
I’m still a little skeptical whenever a vendor throws around AI-powered like it’s a magic wand — trust me, it’s all in the fundamentals. Identity, authentication, monitoring, and segmentation—that’s the true edge. And when you add that to the fact that it’s part of the Fortinet Fabric and a veteran team like PJ Networks, well, now you’ve got something nice and sturdy.
Anyway gotta be moving along here and get the next coffee (there’s always another one, isn’t there?). That’s all for now — stay safe out there, and let’s not take your edge security for granted.
