Home networks have become the backbone of our daily operations. Whether your work from home full time, part time, or only use a personal computer, the home network is an integral part of your day.
But did you know that unmanaged, unknown, and IoT (Internet of Things) devices could be lurking within your network, posing significant risks to your personal and business data?
Do you have children or others living in your home, sharing your home network and internet? Do you or others in your home use TikTok and other social media services? Play online games? Or perhaps more questionable activity like unofficial, unpaid downloads of movies, games, and music?
Do visitors, family, and friends connect to your WiFi?
Here’s the hard truth. Not all security incidents are directed attacks. The people you know and trust might be unwitting carriers of digital threats that can steal your identity or data. Your honor student nephew might have ransomware lurking on his laptop when he asks for your WiFi password. You think you’ll get a headache when your sister-in-law arrives, but she may leave behind bigger headaches when she goes.
Hopefully, your company has comprehensive, multi-layered managed security to protect your business computer and data, but that’s not foolproof, and they have no control over your home network and the other devices connected to it. Threats don’t need passwords to spread and may not be evident to the computer operator if they are present on a computer.
Let’s explore ways to safeguard your digital environment at home.
The Hidden Dangers of Unmanaged Devices
Personal Devices: A Double-Edged Sword
While personal devices enable flexibility and convenience, they can also be gateways for cyber threats. Laptops, smartphones, and tablets used for both personal and business purposes often lack the stringent security measures required to protect sensitive business data.
**Risks Include:
- Malware Infections: Personal devices may not have updated antivirus software, making them vulnerable to malware.
- Data Leaks: Unsecured personal devices can be exploited to access and steal business information.
- Phishing Attacks: Personal devices are prime targets for phishing attempts, potentially compromising business credentials.
Guest Devices: The Unseen Invaders
Guest devices, such as those brought in by visitors, contractors, or even family members, pose an additional risk. These devices connect to your network, potentially introducing vulnerabilities.
**Risks Include:
- Unknown Security Posture: Guest devices might lack proper security configurations, making them easy targets for cyber-attacks.
- Network Overload: An influx of guest devices can strain your network, leading to performance issues and security gaps.
- Data Breaches: Unauthorized access to sensitive business areas could lead to data breaches.
IoT Devices: The Silent Threats
IoT devices, ranging from smart thermostats to security cameras, enhance convenience but often come with minimal security features. These devices can be easily compromised, providing attackers with an entry point into your network.
**Risks Include:
- Weak Passwords: Many IoT devices come with default passwords that users rarely change, making them easy prey for hackers.
- Firmware Vulnerabilities: Infrequent updates can leave IoT devices exposed to new threats.
- Network Mapping: Compromised IoT devices can help attackers map out your entire network, identifying further vulnerabilities.
Strategies to Combat These Risks
-Use a Guest Network
Set up a separate guest network for all visitors. You may trust your brother, but that doesn’t mean you should trust his computer, tablet, or phone. This keeps their devices isolated from your main business network, minimizing the risk of unauthorized access.
-Create Network Segmentation
Divide your network into separate segments for business, personal, and guest devices. This practice limits the spread of potential infections and ensures that critical business data remains isolated by isolating each network from the other. Even most ISP and consumer routers offered today support at least one primary and one guest network. Some support more and you may prefer to that to create network separation.
-Enforce Strong Password Policies
Require all devices, including IoT, to have strong, unique passwords. Regularly update these passwords to maintain security integrity. Use Two Factor Authentication for all devices, websites, and applications that support it even if they don’t enforce it. Always change the default password for any device, including your internet router, printers and other network devices. Use a password manager to help with this. If you can, consult an IT professional, potentially from your company (even if they outsource IT), for advice and recommendations.
-Regular Software and Firmware Updates
Ensure all devices, from personal laptops to IoT gadgets, are consistently updated with the latest security patches. This reduces the risk of exploitation through known vulnerabilities.
-Deploy Advanced Security Solutions
Utilize firewall and antivirus solutions that offer real-time protection and monitoring. These tools can detect and mitigate threats before they impact your network.
-Education and Training
Regularly train your team on cybersecurity best practices. Awareness is the first line of defense against phishing, malware, and other cyber threats. There are also free short videos and courses online to educate yourself and your family on internet and security threats. If children are old enough to use the internet unsupervised, they should learn and understand the risks and how to identify dangers.
-Monitor Network Activity
Use network monitoring tools to keep an eye on connected devices. Identify and address any unusual activity promptly to prevent potential breaches. While this is easier for business networks, there are routers and software to monitor internet activity and better protect against internet threats.
