Zero trust networking aligns closely with the principles of intent-based networking and enhances its security capabilities. It is an IT security model that requires strict identity verification for every individual and device trying to access resources on a private network. Zero trust networking protects modern digital environments by leveraging network segmentation, providing Layer 7 threat prevention, preventing lateral movement, and simplifying granular user-access control. It aims to prevent unauthorized access, minimize the potential attack surface, and protect sensitive data by enforcing rigorous authentication, access controls, and continuous monitoring.
Intent-based networking leverages zero trust networking to provide robust security controls throughout the network. By integrating zero trust principles into intent-based networking solutions, organizations can enforce fine-grained access policies, monitor user and device behavior, and detect and respond to security threats in real time. Also, intent-based networking, with its automation capabilities, can help streamline the implementation and management of zero trust policies. By automating the enforcement of access controls, authentication processes, and network segmentation, organizations can reduce human error, improve security consistency, and respond quickly to changing security requirements.
Over the last decade, there has been a constant need to eliminate the implicit trust associated with traditional network architecture and instead build secure, zero trust networks that can be continuously monitored for malintent. Several enterprise infrastructure providers allow their customers and other trusted third parties to access network resources through the cloud and use their own devices through Bring Your Own Device (BYOD) policies and other ways. Hence, there is a dire need to provide strong security to grant access more securely. Zero trust architecture provides the ability to deny access by default so that attackers cannot access networks. Several organizations are incorporating zero trust principles into intent-based networking solutions to strengthen their security posture and protect their network resources and sensitive data from evolving cyber threats.
Applications of intent-based networking include:
- It prevents lateral movement of threats and contains potential security breaches.
- It can aid organizations in meeting regulatory compliance requirements by providing a framework for continuous monitoring, access auditing, and risk mitigation.
- It helps provide dynamic and adaptive access controls based on user identity, device posture, and contextual information.
- It helps organizations enforce fine-grained access policies, monitor user and device behavior, and detect and respond to security threats in real time.
All such benefits, coupled with the increasing deployment of network automation solutions to simplify zero-trust networking across enterprises, are expected to support the demand for intent-based networking solutions during the forecast period.
