IoT security techniques and best practices
One of the innovations driving the world is the Internet of Things (IoT). Synchronizing digital gadgets has evolved from a convenience to a core part of life for people. We love having our devices in sync, whether at work or leisure because it reduces stress and creates a more personalized experience. Managing critical operations has become easier at the business level. The Internet of Things is used by a variety of industries to boost collaboration and reduce costs, from the medical industry to the construction sector.
Threat actors have been attracted to the increased collaboration and complete synchronization because they can hack one device to gain access to many interconnected devices. It is possible to protect against such attacks by embracing security measures, as we will discuss in this blog. IoT security is essential, but first let’s address whether it is necessary.
Why Internet of Things (IoT) Security?
Humanity takes to new technologies in a very hurried manner, if one observes the technology adoption trend. A lack of appreciation or understanding of the intricacies of technology security is the result of the hype or curiosity surrounding it. In the same way, IoT works. IoT was embraced rather hastily when syncing and seamless collaboration were widely anticipated.
IoT security techniques and best practices
Homeland Security echoed this sentiment by stating that IoT security is one of the department’s top priorities. Furthermore, a survey conducted by 451 Research also indicated that 55% of IT professionals felt IoT security was a priority. Here are the steps you need to take to fortify your IoT setup without further delay.
- Access points centralized in a secure environment
Digital infrastructure can be accessed by anyone with the know-how thanks to the internet of things, which means multiple access points. Inlets such as these are potential entry points for hackers if they are not secured. Centralizing access makes sense because it is time-consuming to monitor all points. As a result of this centralized access, you are able to secure ingrain security wherever it is needed. Aside from that, monitoring the access node would become more accessible due to the ease with which access information can be retrieved.
- Ensure that all protocols are encrypted
Today, every company is at risk of cyberattacks, so encryption is the first line of defense you should put in place. The Internet of Things will be governed by innumerable protocols that govern data management and operational control. Business owners have already realized the importance of encryption and have implemented it into their protocols. This can also be implemented across the organization without much effort.
- Maintain a fluid status for ‘Default Device’
In terms of operational efficiency, default devices are essential. There are certain advantages associated with them, such as ease of access. To throw threat actors off their game, these default devices should be swapped within IoT devices. Switching the default status would prevent unwanted access to all IoT networks, thus securing all IoT networks.
- Third-party and vendor access should be limited
Vendors provide companies with services and deliverables. In the event that credentials are compromised, this can serve as an unintentional inlet for threat actors. Third-party access, including vendor access, should be controlled. The MFA process can be initiated from either a mobile phone or a desktop app. Third-party vendors should be granted access according to protocols that clearly define how they will be able to access the data. One of the zero-trust policies you need to adopt as soon as possible is this one.
- Set up a network control system
Flexible networks are appreciated by all, but they are porous and can allow malware to enter. IoT infrastructure should be integrated with network access software, preventing network breaches. If the organization cannot afford network access software, vulnerability scanners can be used to detect gaps in the network.
- Stay up-to-date
Software tools with static versions are easy targets if they aren’t updated for a long time. The threat actors only have ample time to study the software for vulnerabilities. The IoT devices should be updated regularly and all IoT devices should be updated as well. A potential Achilles heel of IoT is an obsolete device. The implementation of software updates across the infrastructure should be automated as this reduces the chances of a breach occurring.
- Make VLAN investments
All IoT devices are on corporate networks, so they are a preferred target. In the long run, it is better to get rid of the corporate network and replace it with a Virtual Local Area Network (VLAN). VLANs enable organizations to enable individual IoT connections and monitor their connected devices. Also, the monitoring provides statistics regarding the usage of IoT devices for the company.
In terms of productivity, IoT holds enormous potential. A threat actor, however, is everywhere, waiting for an opportunity to compromise networks. Security Partners are essential to protect your business against countless attacks. Their expertise has been used to protect and defend a variety of clients by plugging vulnerabilities.
