Dattatray Katkar, Head of Sales & Strategic Alliances - INDIA & SAARC- Allied Telesis India Pvt. Ltd focuses on the zero-trust security, its principle, unique challenges etc.
Now-a-days Zero trust security is one such security concept that is receiving a lot of attention. Zero trust security is not industry-specific, but it is especially relevant in fields like manufacturing and healthcare where the presence of OT/IoT devices presents special difficulties for conventional security methods.
On this topic Dattatray Katkar says, “In today's digital landscape, the importance of robust security measures cannot be overstated. One such security model that is gaining significant attention is zero trust security. While zero trust security is not specific to any particular industry, it holds particular relevance in sectors like manufacturing and healthcare, where the presence of OT/IoT devices poses unique challenges for traditional security approaches.”
Principle of Zero Trust Security
Zero trust security is based on the idea that all users and devices must first be verified and authorised before being given access to network resources. Zero trust security operates on the presumption that no person or device, whether internal or external, should be automatically trusted, in contrast to traditional security models that mainly rely on perimeter-based defences.
Delving deep about this, Katkar points out, “The concept of zero trust security revolves around the principle of verifying and authorizing all users and devices before granting them access to network resources. Unlike traditional security models that rely heavily on perimeter-based defenses, zero trust security operates under the assumption that no user or device, whether internal or external, should be automatically trusted. This paradigm shift acknowledges the ever-increasing sophistication of cyber threats and the need for comprehensive security measures.”
Unique Challenges of Zero Trust Security
Security issues are brought up by the growth of OT/IoT devices in the manufacturing and healthcare sectors. This is addressed by zero trust security, which lowers the risk of harmful activity by demanding authentication and authorization for all devices. Granular access control reduces the danger of breaches even more, especially in the healthcare industry where patient data is so delicate. Pointing out this Katkar says, “In manufacturing and healthcare industries, the proliferation of OT/IoT devices presents a unique challenge. These devices often lack the capabilities to host traditional antivirus software, making them more vulnerable to cyber-attacks. However, since they are connected to the network, they still pose a potential risk. Zero trust security addresses this issue by requiring authentication and authorization for all devices, regardless of their nature. This ensures that only trusted devices and users are granted access to the network, mitigating the potential for malicious activity.
Another key aspect of zero trust security is granular access control. By implementing this approach, organizations can ensure that users and devices are only granted access to the specific resources they require for their designated functions. This not only reduces the attack surface but also minimizes the risk of a security breach. Healthcare organizations, in particular, handle highly sensitive patient information, making zero trust security vital to safeguarding this data from cyber threats. The repercussions of a breach in this sector can extend far beyond financial and reputational damage, potentially jeopardizing patient safety and well-being.”
In his concluding words, Katkar comments, “Zero trust security is an essential security model for industries such as manufacturing and healthcare, which heavily rely on OT/IoT devices. By adopting this approach, organizations can fortify their networks and protect their valuable data from cyber threats.
Zero trust security not only addresses the limitations of traditional security measures but also provides a comprehensive framework for authentication, authorization, and access control. As the digital landscape continues to evolve, embracing zero trust security becomes paramount to maintaining a resilient and secure environment for both organizations and their stakeholders.”
