What is IoT Cyber Security?

IoT security refers to precautions and defenses for cloud-connected gadgets like home automation, SCADA systems, security cameras, and other hardware that connects directly to the cloud. The automatic cloud connectivity of IoT devices sets it apart from mobile device technology (such as smartphones and tablets). IoT security entails securing historically shoddy-built gadgets for data security and cybersecurity. Recent data breaches have demonstrated the need for most manufacturers and developers to prioritize IoT security.

How IoT Cyber Security Works

Anything that connects to the cloud and gathers data is considered an IoT device. It may be any device that links to the cloud, including locks, garage door openers, temperature monitors (like the Google Nest), refrigerators, security cameras, ovens, and televisions. Modern warehouse equipment frequently connects to the cloud. You'll note that these gadgets are not regarded as mobile, with cybersecurity requirements and a standard operating system. IoT devices run a customized version of the complete software, typically Linux, as their operating system.

IoT devices need cybersecurity regulations because they operate differently than regular mobile devices. They lack the advantages of built-in security measures on mobile devices like iOS and Android. Several data breaches and devastating assaults were conducted against these devices when IoT first gained popularity. IoT security continues to be a problem for many manufacturers and developers today.

IoT security entails safeguarding information from a local device to the cloud. It also guards against the hacking of the actual device. The malware known as Mirai poses a serious concern because owners of IoT devices infrequently alter the default password. Mirai targets Linux-based IoT devices running the default password and adds them to a botnet. Then a distributed denial-of-service (DDoS) attack against the target is launched using this botnet. It is possible to thwart Mirai's brute-force attack on IoT devices by simply changing the default password and disabling Telnet services.

Challenges & Hurdles With IoT Security

IoT makers must take measures to improve device security. However, many IoT security issues include user engagement and awareness. Users may not realize the risks or find it more convenient to use the original password. Manufacturers cannot force users to change the default password or risk losing customers; instead, they must educate users on the importance of doing so.

The lack of updates is another problem. Users must install updates, even if a manufacturer provides a number of them, to address problems and vulnerabilities. Users risk leaving the gadget open to several attacks if they don't upgrade the firmware. Users frequently neglect to look for updates. So they are also not aware that firmware upgrades are available.

It's hardly surprising that Broadcom Symantec is a market leader in IoT security, given the IT giant's network infrastructure and cybersecurity skills. The Integrated Cyber Defense security bundles from Symantec (XDR, SASE, and zero trust) provide all the instruments required to monitor and safeguard IoT devices.

Broadcom additionally provides a location hub microcontroller and System-on-a-Chip (SoC) devices for embedded IoT security for businesses involved in product production.


Cisco, a provider of enterprise networking services, made a significant advancement in industrial security in 2019 when it bought French IoT company Sentryo, now known as Cyber Vision. The synergy has produced optimal visibility into ICS networks with Cisco's current security stack and an adaptive edge monitoring architecture. In addition to Cyber Vision, firewalls, identity service engines (ISE), secure endpoints, and SOAR are other components of the Cisco IoT Threat Defense.


Since 2006, Cradlepoint has developed into a leading provider of WAN, edge networking, and cloud solutions. In September 2020, Ericsson purchased Cradlepoint for $1.1 billion. The vendor from Boise, Idaho, offers LTE and 5G-compatible wireless edge routers with a web-based platform to manage edge traffic and IoT applications as part of its NetCloud Service.

How To Secure IoT Network

Cybercriminals are drawn to IoT devices as tempting targets. When it comes to managing, monitoring, and securing their connected IoT environments, businesses confront comparable difficulties regardless of whether they are just beginning to utilize the Internet of Things or trying to expand their existing IoT networks. There are a few factors that businesses should think about to secure IoT devices adequately.

The Head Count

The first step is to get visibility into the precise number of IoT devices linked to a company's network. Find out what devices are linked to your network and maintain an accurate inventory of all connected IoT assets. Use a dedicated IoT security solution to recognize all connected devices. Gather information on each device's maker and model ID, serial number, hardware, software, and firmware versions, as well as the underlying operating systems and configurations used.

Network Segmentation Equals Better Defense

Network segmentation's security objective is to minimize the attack surface. By dividing a network into two or more portions, network segmentation enables fine-grained control over the lateral movement of traffic between devices and workloads. There is a higher likelihood that a single compromising event can spread laterally to become a contagion in an unsegmented network, in which a significant number of endpoints speak with one another directly without any form of partitioning in place. However, the more a network is divided, the more difficult it is for hackers to compromise a single device to execute lateral assaults.

Secure Password Regimen

Insecure password management procedures still fuel password-related assaults on IoT devices. Maintaining robust password security is essential to protecting your IoT endpoints. Many Internet of Things (IoT) devices ship with weak, easily obtainable preset passwords. It is excellent practice to change the default password on an IoT device as soon as it is initially connected to your network with a secure, more complicated one.

Active Monitoring

Monitoring, reporting, and real-time alerts are essential for enterprises to manage IoT hazards. Typical endpoint security solutions cannot protect IoT assets because they demand software agents that IoT devices cannot accept. Take a more practical stance and ensure all the devices across the internet are accounted for all the time!
