As we rapidly adopt IoT devices—from smart sensors to industrial controllers—the attack surface expands, exposing networks to increased risk. There are five top IoT threats that demand your attention.
1. Expanded Attack Surface
Each new device adds a potential entry point. Without segmentation and visibility, one compromised device can jeopardize your entire network.
2. Insecure Hardware & Default Credentials
Many IoT devices still ship with default or hardcoded passwords. Weak hardware-level security makes it easier for attackers to gain control.
3. Poor Patch Management
Remote or unmanaged devices often miss critical firmware updates. Unpatched vulnerabilities become persistent weak links.
4. Shadow IoT & Visibility Gaps
Unapproved devices—like smart speakers or cameras—can silently connect, bypassing standard security protocols and policies.
5. Botnets & Network Abuse
Compromised devices are often pulled into botnets for massive DDoS attacks. The Mirai botnet is a prime example of how easily this can happen.
How to Protect Your IoT Network
To defend against these threats:
-
Inventory all devices using automated discovery tools.
-
Replace default credentials and enforce strong authentication.
-
Segment networks to isolate IoT from critical systems by putting them on a separate network.
-
Implement routine firmware patching procedures.
-
Disable unused services and harden devices from the start.
Gryphon’s Role in Securing Your Network
Gryphon provides a powerful, AI-powered security layer for home and small business networks. Its intrusion detection, dynamic content filtering, and device-level access control along with an IP isolated IoT network make it ideal for securing IoT environments. Gryphon also helps detect and block suspicious behavior, isolates compromised devices, and simplifies network management—all from an easy-to-use app.
As your IoT footprint grows, integrating a solution like Gryphon can help transform a vulnerable network into a resilient, secure environment for your connected family.
