Zero-Trust network access (ZTNA) focuses on controlling user and device access to applications. Traditionally, perimeter security assumed network users were trustworthy. However, cyber-attacks are growing and becoming more sophisticated, the number of devices, including IoT and smart devices, has rocketed, IT Teams are finding it difficult to control that perimeter. Attacks and malware which exploit user credentials can quickly spread inside the network, causing untold harm.
The ZTNA model extends the principles of Zero-Trust access (ZTA) to continuosly verify users and devices before every application session, confirming that they meet the organisation’s policy to access that application.
To protect networks and applications, network administrators must apply a Zero-Trust access approach and provide least-access privileges. Implementing this Zero-Trust access requires strong authentication capabilities, powerful network access control technologies, and pervasive application access controls.
The Zero-Trust approach assumes every device is infected and every user is capable of compromising the network, whether by accident or not. To adopt this strategy, the IT department should follow a three-step approach.
