Kaspersky’s recent report revealed that sixty-four percent of companies are now incorporating Internet of Things (IoT) solutions, with 57 percent of these organisations ranking cyberattacks as their top concern. A surprising result showed that 43 percent of firms were operating at least one IoT device without adequate security protocols. Though seemingly benign, the doubling of IoT devices per company vastly increases the potential for vulnerable points throughout the business sector. Experts predict a steady 9 percent growth rate in the worldwide use of IoT devices until 2025 (view chart).
The impact of cyberattacks is unmistakable; distracting workers from their duties and besmirching a company’s reputation. As Internet of Things (IoT) devices become even more ubiquitous, businesses must take the necessary measures to secure both their networks and devices. Within this blog post, we will outline several reliable techniques for improving IoT device security.
Specific Uses of IoT
Understanding how the Internet of Things is utilized within your industry is paramount when it comes to bolstering its security. Here are some examples:
Healthcare.Patients with chronic illnesses make use of wearable Internet of Things (IoT) devices, such as fitness trackers, blood pressure watches, and pulse oximeters, to track their condition and transmit data to healthcare providers. Furthermore, televisions and other technologies are utilized by hospitals for monitoring patients’ vitals and the functionality of medical equipment.
Manufacturing.Installing Internet of Things (IoT) sensors on machinery and tools enables the acquisition of data that can enhance manufacturing processes and boost efficiency. This data can also be used to plan and schedule maintenance, repairs, and replacements while taking into account business processes and cash flow.
Logistics.Internet of Things (IoT) connected sensors keep tabs on package locations throughout transit, provide information on warehouse contents, and monitor vehicle status.
Automotive.Having a fully wired vehicle provides a variety of benefits, including autonomous driving, directly transmitted maintenance notifications, and real-time location updates.
Retail.Thanks to sensor technology, brick-and-mortar stores are now able to provide enhanced services to clientele such as advanced fitting rooms, updated product information, and speedy grab-and-go options.
Please Be Aware of the Following
In the past, cybercriminals had fewer access points which limited their opportunities. Conversely, the prevalence of billions of Internet of Things (IoT) devices provides hackers with multiple entry points through botnet distributed denial of service (DDoS) attacks targeted at IoT devices. These attacks can prove detrimental to businesses by bringing about website outages and causing financial loss along with damaging a reputation. Other attacks might lead to data loss or the exposure of sensitive or confidential information.
To ensure a robust IoT cybersecurity approach, the first step is to gain a comprehensive understanding of your entire digital landscape. This includes everything from sensors on delivery packages and manufacturing machinery to the smart fridge in the employee lounge. Because connected devices may have been dispersed across different departments, it is essential for IT to consolidate all data into a centralized device repository and assess the security of each device.
Formulate a Plan of Action
After pinpointing security vulnerabilities, the following course of action is to create and execute solutions. We recommend beginning by adhering to the comprehensive procedures detailed below.
Adopt rigorous security measures.A recent article on TechRepublic stressed the significance of a Zero Trust security approach: the belief that all networks, machines, and users are susceptible and at risk of infiltration, regardless of their familiarity with potential dangers.
Establish a mechanism for detecting and remedying security weaknesses.Effective risk management necessitates a methodical approach, which a vulnerability management program provides.
For peak performance, utilise an Internet of Things gateway.To connect sensors, IoT modules, and smart devices with the cloud, an Internet of Things (IoT) gateway platform is required.
Take charge of the Internet of Things.Critical aspects of this approach include thoroughly examining and authenticating each new device in line with the manufacturer’s guidelines, safeguarding personal information to the highest degree, and following all security standards.
Devise a strategy for safeguarding against cyberattacks.The routing of interconnected Internet of Things (IoT) devices through intermediate systems, without any additional security features, is known as ‘cyber immunity’ and can increase a system’s resilience to certain types of attacks.
Subsequent to the enactment of these measures, the continuous monitoring of each device, with regular security audits, is a necessity.
Minimize the Impact on Other Parties
Even if you have taken comprehensive measures to ensure the highest level of cybersecurity in-house, it is critical to implement Zero Trust protocols for third-party providers. These vendors’ workers may have the ability to access your systems, which is why you must treat them the same way you would treat any of your own personnel. Neglecting to do so could jeopardize your entire organisation.
Assessing the security protocols of any organisations you collaborate with or are considering collaborating with is crucial to ensuring they fulfil your security specifications. As part of your due diligence, it is advisable to build internal security evaluation and remediation systems, and verify with your current suppliers if they comply with your ethical standards.
Create a Safety and Security Plan
After performing a comprehensive evaluation of the specific hazards in your industry, surveying your digital environment, and implementing measures to mitigate potential threats from both internal and external sources, create a meticulous cybersecurity playbook that outlines the rules to be followed. This playbook should provide information on system security, threat detection and response, team collaboration, and data recovery in case of a breach.
Consider Other Alternatives
It is prudent to suppose that your Internet of Things lacks adequate protection and to make the necessary efforts to correct this. Investing time in ensuring the security of your system will be advantageous in the long run, as it will decrease the likelihood of data loss and minimise anxiety, ultimately preventing any catastrophic data crises.
