In this digital age, cyber attackers seek to exploit vulnerabilities in our personal data. We often overlook the susceptibility of two important technological domains. These are the Internet of Things (IoT) and Operational Technology (OT). From smartphones to building systems, these domains encompass a wide range of devices. As the boundaries between IT, OT and IoT blur, it is crucial for individuals and organizations to reevaluate their strategies in addressing cyber risks.
Microsoft Security, a front-runner in the segment of cybersecurity, has offered a roadmap to strengthen defenses against the modern-day threats that lurk in the shadows of IoT and OT. Here are the key steps recommended to bolster security:
Collaborate with Stakeholders
In a world where digital and physical domains intertwine, working closely with stakeholders is the first line of defense. This collaborative approach helps in understanding the nuances of critical assets and their vulnerabilities.
Map Your Business-Critical Assets
Creating a detailed map of important assets in both IT and OT is really important. This mapping exercise unveils the potential weak spots that may be exploited by malicious actors.
Device Visibility
Organizations must strive for complete device visibility within their enterprise. This entails knowing the exact count of IT, OT and IoT devices, their points of convergence, and the critical data, resources, and utilities accessible through these devices.
Conduct a Risk Analysis on Critical Assets
Understanding the potential risks and their impacts is important. A robust risk analysis should focus on the business implications of various attack scenarios including disruptions to industrial processes and physical damage to equipment.
Define a Strategy
Once the risks are identified, it is time to formulate a strategy. This strategy should be tailor-made to address the identified risks, prioritizing actions based on their impact on the business.
Adopt Comprehensive Security Solutions
To strengthen defenses, adopting a comprehensive and dedicated security solution is crucial. This solution should encompass visibility, continuous monitoring, attack surface assessment, threat detection and a swift response mechanism.
Educate and Train
An educated workforce is your greatest asset in the battle against IoT and OT threats. Incident responders and security specialists should receive specialized training to better understand their environments and effectively investigate potential incidents originating from or targeting IoT/OT systems.
