Quick Answer: IoT device security means protecting cameras, locks, thermostats, and voice assistants from unauthorized access. For high-net-worth households, the risk is higher because these devices sit on the same network as financial accounts and family communications.
A smart thermostat doesn’t feel like a security risk. Neither does a video doorbell, a robot vacuum, or the voice assistant on the kitchen counter. But every one of those devices is a small computer with a network connection, and every network connection is a door. Most of them were built for convenience first and locked down as an afterthought.
That gap matters more for households with real assets to protect. A compromised camera or router isn’t just an inconvenience – it can hand an attacker a live feed of your home, a foothold onto the same network your family uses for banking and email, or a data point that feeds into a much larger profile of your routines, your property, and your family. The more valuable the target, the more useful that foothold becomes.
This guide walks through what IoT device security actually covers, why it matters more for high-value households, how devices get compromised in practice, and the concrete steps that close most of the gap.

Key Takeaways
- IoT device security means protecting internet-connected cameras, locks, thermostats, and assistants from unauthorized access, monitoring, or hijacking.
- The average US household now runs 22 connected devices, and homes with 20 or more report data breaches at roughly triple the rate of homes with fewer than 10.
- Home network compromise has become one of the most common consequences of attacks on executives and high-net-worth principals, according to 2025 Ponemon Institute research.
- Most IoT breaches trace back to weak defaults: factory passwords, unpatched firmware, and devices sitting on the same flat network as sensitive accounts.
- The FCC’s new U.S. Cyber Trust Mark label helps buyers spot devices tested against a baseline security standard before they ever join the network.
- Network segmentation, unique credentials, and routine firmware updates close most of the gap – Batten Black coordinates this work end-to-end for families who want it handled rather than DIY’d.
What Is IoT Device Security?
IoT device security is the practice of protecting internet-connected hardware – the “Internet of Things” – from unauthorized access, data theft, or remote control. It covers the device itself, the app that manages it, the cloud service it phones home to, and the home network that ties it all together.
The category is broader than most people assume. A single household today typically includes:
- Entry and Perimeter Devices: Smart locks, video doorbells, garage door openers, and security cameras
- Climate and Utility Devices: Smart thermostats, water leak sensors, and connected sprinkler systems
- Voice and Media Devices: Smart speakers, streaming boxes, and smart TVs
- Convenience Devices: Robot vacuums, smart plugs, connected appliances, and pet feeders
- Network Infrastructure: The router and mesh Wi-Fi system that every other device depends on
The NIST Profile of the IoT Core Baseline for Consumer Products defines the outcomes a genuinely secure consumer device should meet: it should be uniquely identifiable, configurable away from insecure defaults, capable of protecting the data it handles, able to restrict interface access to authorized users, and updatable through a secure mechanism. Most budget smart home products on the market today fall short of at least one of these outcomes.
Why High-Net-Worth Homes Are Higher-Value Targets
Every household adding smart devices takes on some risk. But the math changes for families with significant assets, public profiles, or business exposure. A compromised camera in an average home might expose a burglary opportunity. A compromised camera in a principal’s home can expose a floor plan, a family’s routine, a business call held in the study, or a live feed useful for staging a physical intrusion.
This is precisely the exposure Batten Black was built to manage – coordinating digital, residential, and identity risk as one strategy instead of a pile of disconnected devices and vendors.
Ponemon Institute research sponsored by BlackCloak found that attacks targeting business leaders climbed from 43% of surveyed organizations in 2023 to 51% in 2025, and that home network compromise has risen to become one of the most common consequences of those attacks, trailing only financial loss and intellectual property theft. The report also found that a majority of security leaders expect digital attacks on executives to escalate into physical harm.
The scale of the underlying threat is not abstract. The FBI’s Internet Crime Complaint Center recorded $16.6 billion in reported losses across 859,532 complaints in 2024 – a 33% jump from the year before, with the average victim losing $19,372. High-net-worth households are disproportionately represented in that data because they simply have more to take.
Do IoT Devices Pose a Security Threat? How They Actually Get Compromised
Yes – and not in a theoretical sense. IoT devices pose a real and well-documented security threat, and the failure patterns repeat across nearly every major incident.
Default Credentials and Unpatched Firmware
The single most common failure is a device shipped with a default username and password that’s never changed, paired with firmware that never gets updated. The FTC’s consumer guidance on securing internet-connected devices puts the router at the center of this problem: nearly every connected device in the home routes through it, so a weak router password compromises everything behind it.
This exact weakness powered the Mirai botnet, one of the most consequential IoT attacks in history. Mirai scanned the internet for cameras, routers, and DVRs still running factory-default Telnet credentials, and by late 2016 had recruited an estimated 300,000-plus devices into a botnet capable of knocking major websites offline.
KrebsOnSecurity’s own coverage of the case documents how three college students built the malware to attack rival Minecraft servers, and it ultimately grew into a weapon used against journalists, hosting providers, and internet infrastructure worldwide. None of the compromised devices were exotic – they were the same consumer cameras and routers sitting in millions of ordinary homes.
Cloud Account and Access Control Failures
Even a well-built device can be undone by weak controls around the account and company behind it. In 2023, the FTC charged Ring with giving employees and contractors sweeping access to customer camera feeds and failing to implement basic protections like multi-factor authentication, which let hackers take over accounts and view live video inside customers’ homes.
Ring ultimately paid $5.8 million to settle the case. The lesson for buyers: the device’s security is only as strong as the company’s internal access controls and account protections, and those are invisible until something goes wrong.
Flat Networks With No Segmentation
The third failure pattern is architectural. Most home networks put every device – the smart plug, the guest’s phone, the laptop with online banking open – on the same flat network. One weak device becomes a bridge to everything else, a technique security researchers call lateral movement.
Router Hardening: The Foundation of Home IoT Security
Every mitigation further down this guide assumes one thing is already true: the router itself is locked down. Skip this step and segmentation, strong device passwords, and everything else built on top of it inherits the same weakness.
Why the Router Comes First
CISA’s guidance on securing the Internet of Things frames it plainly – once a device connects to the internet, it’s connected to millions of other machines, and the router is the checkpoint standing between them. A hardened router blocks most opportunistic scanning before it ever reaches the smart lock, camera, or thermostat behind it. A weak one hands an attacker the keys to the entire home network in one step.
Essential Settings to Change Today
The table below covers the settings that matter most, in the order they should be addressed.
| Setting | Why It Matters | Recommended Action |
| Admin Username & Password | Default credentials are published online for nearly every router model | Replace both with unique, generated values stored in a password manager |
| Network Encryption | Older protocols like WEP and WPA are trivially broken | Enable WPA3, or WPA2-AES if WPA3 isn’t supported |
| Network Name (SSID) | A default SSID reveals the router make and model to attackers | Rename it to something that doesn’t identify the hardware or household |
| Firmware Updates | Unpatched routers are the most common entry point in home network compromises | Enable automatic updates or check monthly if unsupported |
| Guest / IoT Network | Isolates smart devices from primary devices and accounts | Enable and dedicate exclusively to IoT devices |
| UPnP (Universal Plug and Play) | Convenient but lets devices open ports automatically, which malware can exploit | Disable unless a specific device requires it during setup |
| Remote Management | Allows router configuration from outside the home network | Disable unless actively needed, and never leave on by default |
Most of these settings take under fifteen minutes to configure through a router’s admin panel, and they close off the majority of the attack paths documented in CISA’s home network guidance.
Smart Cameras, Voice Assistants, and Family Privacy
Beyond network-level compromise, some IoT categories carry a privacy risk that has nothing to do with hacking at all – it comes from how much the device sees and hears by design.
What Cameras and Doorbells Actually Collect
Video doorbells and indoor cameras don’t just capture footage of intruders. They capture every family member, guest, contractor, and staff member who passes through the frame, along with timestamps that reveal exactly when the house is occupied or empty. That footage typically lives in a manufacturer’s cloud, governed by whatever access controls and employee policies that company has in place – which, as the Ring case demonstrated, aren’t always as strong as customers assume.
Voice Assistants and Always-On Microphones
Smart speakers listen continuously for a wake word, which means a low-level audio stream is always being processed. Misfires happen, and stored voice history can include conversations never meant to be recorded. This isn’t usually a hacking risk so much as a data-retention risk: the recordings exist somewhere, and it’s worth knowing where.
A short list of settings worth checking on every camera and voice device in the house:
- Cloud Storage Retention Window: How long footage or recordings are kept before automatic deletion
- Employee/Third-Party Access Policy: Whether the manufacturer discloses who can view stored footage and under what circumstances
- Voice History Review and Deletion: Most assistants allow reviewing and bulk-deleting stored voice recordings
- Local vs. Cloud-Only Storage: Devices offering local storage reduce dependence on a third party’s security practices
- Privacy Zones and Muting: Physical mute switches or software privacy zones that block specific areas from recording
Are Your Smart Home Devices Secure Right Now? A Quick Self-Audit
Before addressing how to secure IoT devices, it helps to know whether yours already show warning signs. Run through this list:
- Unusual Network Activity: A device transmitting data at odd hours or using far more bandwidth than its function requires
- Unexplained Password Resets: Login alerts or password-reset emails for smart home accounts you didn’t initiate
- Device Behaving on Its Own: Lights, locks, or cameras activating without a corresponding app command
- Default Credentials Still in Place: Any device you set up and never changed the admin password on
- Firmware Untouched Since Setup: A device with no update history in its companion app since the day it was installed
- Guest or Old Devices Still Connected: Former house-sitters, contractors, or discarded devices still showing as active on the network
If two or more of these apply, treat it as a signal to move to the hardening steps below rather than a coincidence.
How to Secure IoT Devices on Your Home Network: Segmentation Strategies
Network segmentation is the single highest-leverage step in securing home IoT devices, because it limits what a compromised device can actually reach. The idea is simple: don’t let the smart light bulb sit on the same network as the laptop with financial statements open.
| Approach | What It Does | Effort Level | Best For |
| Guest Wi-Fi Network | Isolates IoT devices from primary devices using router-native guest mode | Low | Most households; a strong starting point |
| VLAN Configuration | Creates fully separate virtual networks with granular firewall rules | Moderate–High | Tech-comfortable households wanting fine control |
| Dedicated IoT Router | Runs smart devices through a second physical router bridged to the main network | Moderate | Households wanting a hard physical separation |
| Managed Security Advisory | A professional maps, segments, and monitors the network on your behalf | Low (for the household) | High-net-worth families and executives – this is where Batten Black coordinates the assessment and remediation directly |
For most families, starting with a guest network dedicated exclusively to smart devices captures the bulk of the benefit with minimal technical overhead. Households with a larger device footprint, staff, or frequent visitors benefit from VLANs or a dedicated IoT router, since these approaches allow different trust levels for different categories of devices – cameras separated from voice assistants, separated again from guest devices.
A Practical Checklist: How to Keep IoT Devices Secure
Once segmentation is in place, the rest of the work is routine maintenance. Here’s how secure IoT devices stay that way over time:
- Change Every Default Password: Every device, not just the router – including cameras, thermostats, and smart plugs that ship with printed default credentials
- Enable Automatic Firmware Updates: Most modern devices support this; manufacturers that don’t offer a minimum update-support window are a red flag under NIST’s consumer IoT baseline
- Turn On Multi-Factor Authentication: Every companion app and cloud account tied to a smart device, not just email and banking
- Use a Password Manager for Device Credentials: Unique, generated passwords for every device account rather than reused ones – Batten’s password manager collection covers vault options built for exactly this kind of sprawl
- Route Sensitive Traffic Through a VPN: Particularly for remote access to home cameras or systems while traveling – see Batten’s VPN collection for vetted options
- Audit Connected Devices Quarterly: Remove anything unused, unrecognized, or belonging to a former staff member or house guest
- Monitor for Identity Exposure Tied to Smart Home Accounts: Batten’s identity protection collection covers monitoring for the account credentials and personal data that smart home breaches frequently expose
- Consider an All-in-One Suite for Device-Level Protection: Bundled antivirus, VPN, and identity monitoring reduce the number of separate tools a household has to manage – see Batten’s all-in-one digital security collection
The table below breaks this down by device category, since the right mitigation varies depending on what the device actually does.
| Device Category | Example Devices | Primary Risk | Key Mitigation |
| Cameras & Doorbells | Ring, Nest, Arlo | Live feed access, footage exposure | MFA, unique password, reputable brand with audited cloud security |
| Smart Locks | August, Schlage Encode | Unauthorized physical entry | Bluetooth-only fallback, firmware updates, avoid cloud-only models |
| Voice Assistants | Alexa, Google Home | Eavesdropping, account takeover | Mute when not in use, review voice history, MFA on linked account |
| Thermostats & Sensors | Nest, Ecobee | Occupancy pattern exposure | Local control mode where available, network segmentation |
| Routers & Mesh Systems | Eero, Orbi, ASUS | Full network compromise | Change default admin credentials, WPA3 encryption, firmware auto-update |
How Secure Are IoT Devices Compared to Traditional Computers?
Generally, less secure – and that gap is closing slowly. Laptops and phones receive frequent security patches and run antivirus software as standard practice. Most smart home devices receive infrequent updates, run stripped-down operating systems with minimal built-in defenses, and are managed through apps that vary wildly in quality from one manufacturer to the next. That disparity is exactly why segmentation matters: it treats IoT devices as the less-trusted category they currently are.
The US Cyber Trust Mark: A New Way to Buy Safer Devices
Buyers have historically had no easy way to compare device security before checkout – a gap the government has started to close. The FCC’s U.S. Cyber Trust Mark program is a voluntary labeling initiative that lets manufacturers display a shield logo, paired with a scannable QR code, on consumer IoT products that meet baseline cybersecurity standards drawn directly from NIST’s IoT framework.
What the Label Actually Tells You
| Label Element | What It Confirms |
| Shield Logo Presence | The product passed independent testing against NIST’s consumer IoT baseline |
| QR Code | Links to a public registry with specifics on the device’s security posture |
| Minimum Support Period | How long the manufacturer commits to shipping security updates |
| Automatic Update Status | Whether patches install automatically or require manual action |
| Default Password Guidance | Instructions for changing default credentials during setup |
The program covers categories like connected cameras, voice-activated devices, smart appliances, fitness trackers, and baby monitors. It does not currently apply to routers, though NIST is developing a parallel baseline for consumer-grade routers specifically because of how central they are to overall network security.
Questions to Ask Before Buying a New Smart Device
The label helps, but it’s still worth running through a short list before anything new joins the network:
- Does it carry the Cyber Trust Mark, or does the manufacturer publish an equivalent security disclosure?
- What is the minimum guaranteed support window for security updates?
- Does the device support local control, or does every function route through the manufacturer’s cloud?
- Can multi-factor authentication be enabled on the companion account?
- Does the company have a public track record of disclosed breaches or FTC enforcement actions?
A device that fails several of these questions isn’t automatically off-limits, but it belongs on the guest network, not the primary one.
Taking Control of Your Connected Home’s Security
Smart home technology isn’t going away, and it shouldn’t have to. The average household now runs 22 connected devices, and that number is only going in one direction. What matters is treating each new device as a deliberate addition to the household’s attack surface rather than a plug-and-play convenience.
The households facing the highest stakes – those with significant assets, public visibility, or executive exposure – can’t rely on default settings and hope. Segmentation, credential hygiene, and routine monitoring close most of the gap, and the remainder comes down to having someone accountable for watching it continuously.
That’s the gap Batten Black was built to close: one dedicated advisor coordinating digital, residential, and identity risk as a single strategy, rather than a stack of disconnected devices and vendors nobody is actively managing.

Frequently Asked Questions
Are My IoT Devices Secure by Default Out of the Box?
No. Most consumer IoT devices ship with default administrator credentials and minimal built-in protections, prioritizing easy setup over security. Manufacturers increasingly disclose minimum update-support windows under frameworks like NIST IR 8425, but the device itself still requires the owner to change default passwords and enable available security features.
Do IoT Devices Pose a Security Threat to Home Wi-Fi Networks?
Yes. A single compromised device on a flat, unsegmented network can act as a bridge to laptops, phones, and financial accounts sharing that same network. This lateral-movement risk is why network segmentation, not just device-level passwords, is considered essential for households with meaningful digital or financial exposure.
How Secure Are IoT Devices When Used With a Smart Speaker or Assistant?
Voice assistants add a data-exposure risk beyond typical devices, since they process audio and can be triggered to record unintentionally. Reviewing voice history settings, muting microphones when not needed, and enabling multi-factor authentication on the linked account meaningfully reduce this exposure without giving up core functionality.
How Do I Secure IoT Devices on a Home Network Without Replacing My Router?
Most modern routers include a built-in guest network feature that can isolate IoT devices from primary devices without any additional hardware. Enabling this, changing the router’s default admin credentials, and updating firmware covers the majority of home network hardening for a typical household.
How Can I Keep IoT Devices Secure Once They’re Set Up?
Ongoing security comes down to routine maintenance: automatic firmware updates, unique passwords stored in a password manager, quarterly audits of connected devices, and multi-factor authentication on every companion app. Households with a larger footprint of devices, staff, or visibility often bring in a dedicated advisory service to handle this continuously rather than manage it piecemeal.
Does the US Cyber Trust Mark Mean a Device Is Fully Secure?
Not entirely. The Cyber Trust Mark confirms a device passed independent testing against a baseline security standard, covering things like default password practices and update commitments. It’s a useful signal at the point of purchase, but it doesn’t replace network segmentation, strong credentials, or ongoing monitoring once the device is installed.
