or give out company details, and should connect only from secure networks. Tis advice helps companies limit their exposure to ransomware attacks. However, what happens if your system is already infected? Te UK government offers a guide (the Code of Practice for
Consumer IoT Security) how to help those impacted by infected devices. Advice includes suggestions of immediate disconnection from the network, resetting credentials, safely wiping devices, and more.
Protecting your IoT devices IoT devices are found everywhere nowadays, since they provide monitoring and data gathering in many applications, across all sectors. However, IoT connections also provide more access points to digital systems, which can be exploited by cybercriminals. With the number of IoT devices expected to increase to 25.4 billion by 2030, exposure to cyberattacks will increase. Te growing use of IoT devices encourages more advanced
updates of the technology. One way of learning more about the systems they fit into is with “digital twins” – virtual systems that replicate the business operations in the digital world. Te technology exists to give companies insight into their operations for their improvement, increased efficiencies and tackling problems away before implementing them in the real world. However, digital-twin technology also holds a goldmine of data, exposing the access points that cybercriminals could potentially exploit. Edge computing can be added to limit data exposure, but on its own this solution doesn’t erase all the risks. Companies should start securing their IoT devices from the
ground up. For a start, there should be a two-factor authentication for each device, companies should have regular audits of all their
connected devices and also have a built-in firewall. In addition, monitoring data at the physical layer, where it is generated, can help spot changes in data transactions that might signal a cybersecurity threat. A company offering this approach is IXDen, which developed a soſtware-based solution that not only allows companies to monitor the cybersecurity of their connected equipment but also act as a predictive maintenance system.
Preventing business disruptions Supply chain attacks can cause mass disruption to a business by taking down its soſtware supply chain and services. Tere are many methods a cybercriminal could use to attack a supply chain, for example by attacking website builders, third-party soſtware providers or data stores, or by carrying out a “watering hole” attack. Supply chain attacks have recently become a bigger concern
for cybersecurity. A 2021 report by ENISA suggested strong security protection alone is not enough to protect against attacks when they target manufacturers’ suppliers. So, if strong security protection alone is not effective against supply chain attacks, what can be done? Microsoſt advises using strong code integrity policies, allowing
only authorised apps to run, and using endpoint detection and response solutions to spot suspicious activities. Security companies are already developing advanced and comprehensive solutions. For example, embedded AI-based SSD company Flexxon’s X-PHY provides secure data transfers and storage. Te list of such technology companies is growing, enabling
secure and unimpeded adoption of IoT devices in all sectors. Te key to the best defence is to better know your device and network vulnerabilities, to protect them better.
A record number of ransomware attacks were reported in 2021, with governments worldwide seeing a 1,885% increase in cyberattacks
