How to secure your IoT devices

More firms are using the Internet of Things (IoT) to create new business opportunities. For instance, companies that install smart sensors can automate data entry and monitor their inventory. However, if left unsecured, IoT devices also give hackers an opportunity to breach your network. In order to keep attackers at bay, we advise you take the following precautions with your IoT devices.

Set passwords
Many often forget they can set passwords for IoT devices. When this happens, they tend to leave their gadgets with default passwords, essentially leaving the door open for hackers. Make sure to set new and strong passwords — preferably with a combination of upper and lower case letters, numbers, and symbols — for each device connected to your network. Then, use a password manager to securely keep track of all your passwords.

Disable Universal Plug and Play (UPnP)
UPnP is designed to help IoT gadgets discover other network devices. However, hackers can also exploit this feature to find and connect to your IoT devices. To prevent them from getting to your network, it’s best to disable this feature completely.

Create a separate network
When you’re dealing with IoT devices, it’s wise to quarantine them in a separate network unconnected to your main office network. By doing this, user gadgets will still have access to the internet but won’t be able to access mission-critical files.

You should also consider investing in device access management tools. These allow you to control which devices can access what data, and prevent unauthorized access.

Update your firmware
If you want to keep your devices secure against the latest attacks, then you need to keep your IoT software up to date. Security researchers are always releasing security patches for the most recent vulnerabilities, so make it a habit to regularly check for and install IoT firmware updates. If you have several gadgets to secure, use patch management software to automate patch distribution and set a schedule to check for updates monthly.

Unplug it
Disconnecting your IoT devices from the internet (or turning them off completely) whenever you don’t need them significantly reduces how vulnerable you are to an attack. Think about it, if there’s nothing to target, hackers won’t be able to make their move. Turning your IoT devices on and off again may not seem like the most convenient strategy, but it does deny unauthorized access to your router.

Unfortunately, as IoT devices become more commonplace in homes and offices, more hackers will develop more cunning ways to exploit them. Getting into the above mentioned security habits can protect you from a wide variety of IoT attacks, but if you really need to beef up your security, then contact us today. We have robust security solutions that keep your hardware safe.

Dark Cubed:

Dark Cubed focuses on real-time monitoring, threat intelligence, predictive analytics, elegant dashboard, streamlined workflow, executive reporting and active blocking. This is another layer of security that integrates with the firewall.

ThreatLocker:

ThreatLocker is a zero-trust endpoint security tool giving companies control over what software can run, by whom, and what data can be accessed.

It keeps a full detailed audit of what applications are used and data accessed/transferred/deleted and by what users (signature tracking, etc.) If something unusual happens, such as a signature change, or a user opens an application that is out of their normal routine the administrator is alerted. This is a crucial tool in identifying malware threats, as well as helping organizations identify if users are accessing applications and/or data/ files they should not be.

ThreatLocker provides a solution that allows businesses to control the content that runs on their network. Unlike AntiVirus software ThreatLocker is not looking for known viruses or malware. ThreatLocker uses a complex set of rules to determine what can be executed on a network and stops anything that has not been approved before it can even execute.

Huntress:

Huntress is a supplement to SentinelOne. Hackers are becoming more sophisticated, and Huntress actively seeks out these threat actors with a "defend forward" mentality. This software combines both advanced security tools along with human intervention to ensure even the most advanced hackers can't penetrate your network.

SentinelOne:

SentinelOne is a comprehensive enterprise security platform that provides threat detection, hunting, and response features that enable organizations to discover vulnerabilities and protect IT operations. SentinelOne integrates static artificial intelligence (AI) to provide real-time endpoint protection and reduce false positives that derail investigations or make threat detection a capital-intensive process. This will replace Webroot in your current environment.
