Zero Trust Network Access (ZTNA): Secure Access Without Trusting the Network
The traditional VPN-based security model assumes that once users are inside the network, they can be trusted. However, with remote work, cloud computing, and sophisticated cyber threats, this approach is no longer sufficient. Zero Trust Network Access (ZTNA) provides secure, identity-based access without granting broad network access. What is Zero Trust Network Access (ZTNA)? Zero Trust Network Access (ZTNA) is a security model that grants users access only to the specific applications and resources they are authorized to use, based on continuous verification of identity, device health, and security policies. ZTNA follows the Zero Trust principle of "Never Trust, Always Verify." Why ZTNA is Important Eliminates implicit trust Supports remote and hybrid work Reduces the attack surface Prevents lateral movement by attackers Improves secure access to cloud and on-premises applications How ZTNA Works User requests access to an application Identity is verified using authentication...
