At the heart of Internet connectivity is the Internet of Things (IoT). Every enterprise today that utilizes digital technology in its core processes or organizational infrastructure adopts some form of IoT.
While these connections can give businesses the dynamic they need to compete in an increasingly competitive market, they can also add to a company’s online vulnerability. The countless devices, applications, cloud platforms, sensors, systems, and modems that are connected all present a threat to an enterprise’s most core secure data and personnel profiles.
If at any given time any of these devices become vulnerable, the entire network — and all devices and platforms within it — becomes exposed. For this reason, companies must take multi-layered approaches to secure the devices and the data that travels between each device throughout every second of every day.
Here are five ways companies can improve enterprise security, both internally and externally throughout an IoT-driven network.
1. Assume that everything presents risks
The first rule of thumb in business security is to question the security of every current device and any additional device within the business network. Every device and component within a network is vulnerable in one way or another. Therefore, IT administrators must understand the risks involved with adding a device and then apply security protocols appropriate to the level of risk.
A simple example of this would be the addition of a router to the network. Since the router links other devices together to the outside world, it is highly exploitable. Rather than settling for the router default configurations, administrators can tighten security by adjusting the setting in the following ways:
2. Assess all IoT device security characteristics
IoT security methods vary depending on a wide range of variable both within the device and within the network. Unfortunately, most IoT manufacturers do not place a high priority on securing these devices. As a result, IT techs and administrators must do it upon installation. Similar to the above point, all IoT devices must be assessed for security characteristics.
What characteristics in each device do IT administrators look for?
3. Look to a Virtual Private Network (VPN)
A VPN gives a company privacy and anonymity by creating a private network from a public internet connection. A VPN masks an internet protocol (IP) address so that no other entity can trace any online actions. By combining a VPN with the best browser for privacy, a company has a greater chance of optimizing security.
Regardless of how many IoT devices you have connected to your network or the activity that transpires between the devices, the VPN shields all activity from those trying to access or hack the data.
While you may consider other types of security to add to your network, a VPN is your greatest line of defence against business-related online criminal activity. A virtual private network can conceal enterprise activity such as:
4. Expand existing security solutions
Every IoT device adds another connection endpoint. Eventually, enough devices can exhaust the security of an existing system. Therefore, users may need to expand the existing security solutions to mitigate IoT risks.
Here are some ways to achieve this:
Start with the End User in Mind
Breaches occur when a company employee (end-user) doesn’t understand the security protocols, or they access a part of the network that they were not supposed to. Therefore, companies need to regulate and control which devices end-users connect to the network.
Shield the Network Perimeter
Design and implement a security policy for an IoT based network, paying special attention to items such as device authentication to the network, device network communication controls, and device logging. These devices lack hardened operating systems. They are vulnerable to hacks.
Multi-Layer Endpoint Protection
Hackers are always testing systems for weaknesses. The slightest opening in a network will allow a hacker to wreak havoc on a company. Companies can block criminals at every point through risk-based authentication. Another possible solution is utilizing encryption keys to hide the identity of an IoT device.
5. Be prepared for worst case scenarios
We’ve all seen the headlines over the past decade of what can happen when a seemingly impenetrable mega corporation experiences a security breach. In most cases, the breaches occurred because the company did not take the security of its data seriously enough.
Cybersecurity must be the top priority for today’s companies. Every new development ushers in countless hackers who are already ahead of the curve and waiting for companies to display some type of vulnerability with their network.
How can companies prepare for worst case scenarios?
By utilizing these five strategies, small, medium, and large companies can ensure that the devices and platforms within their network system are safe from hackers and criminal activity. The simple fact is, companies can no longer access the web and neglect enterprise security.
