Zero Trust Network Access (ZTNA)

Zero Trust Access (ZTA) in Fortinet Security Fabric

• Primary focus of ZTA is to ensure secure access to resources and applications.
• ZTA is a key component of the Fortinet Security Fabric approach to cybersecurity.

Multi-Factor Authentication (MFA)

• MFA contributes to a zero-trust network by adding an additional layer of security to verify user identities.
• MFA ensures that users are who they claim to be, reducing the risk of unauthorized access.

Role-Based Access Control (RBAC)

• RBAC is significant in identity management within Fortinet Security Fabric as it assigns access based on user roles.
• RBAC ensures that users only have access to resources and applications necessary for their job functions.

Key Area of Zero Trust

• Knowing "who is on the network" is a key area of zero trust as it enables the identification of authorized users and devices.
• This knowledge is critical in preventing unauthorized access to resources and applications.

Fortinet Security Fabric Approach

• Fortinet Security Fabric approaches cybersecurity by providing a comprehensive and integrated security framework.
• The framework includes ZTA, MFA, RBAC, and other security features to protect against cyber threats.

Zero Trust vs. Traditional Network Security

• ZTA differs from traditional network security approaches by assuming that all users and devices are untrusted by default.
• ZTA verifies the identity and permissions of users and devices before granting access to resources and applications.

Post-Configuration Tasks

• After configuring remote authentication servers or a local user database, users and devices must be assigned to the correct policies.
• Policies determine the level of access granted to users and devices.

FortiAuthenticator Policy Management

• FortiAuthenticator determines which policy to use when processing a RADIUS authentication request based on the user's identity and role.
• If there is no matching policy, FortiAuthenticator denies access to the user.
• Policies are used to determine access control and authentication settings for users and devices.
• RADIUS clients can be assigned to policies to ensure consistent access control and authentication settings.

ZTNA (Zero Trust Network Access)

• ZTNA connects users to applications regardless of their location, ensuring secure and controlled access.
• ZTNA differs from traditional VPNs in terms of access control, as it provides granular control over user access to applications and resources.
• ZTNA stands for Zero Trust Network Access.

Endpoint Access and Control

• The primary benefit of role-based access in zero-trust principles is to ensure that users only have access to resources and applications necessary for their job functions.
• The most challenging area in zero trust is often device discovery and control.
• Device discovery and control are crucial in zero-trust principles as they ensure that only authorized devices have access to resources and applications.
• Endpoint protection is critical in zero-trust architecture as it ensures that devices are secure and compliant with security policies.

VPNs vs. ZTNA

• VPNs are considered to have high overhead when accessing cloud-based resources due to the need to establish a secure connection to the VPN server.
• ZTNA differs from VPNs in terms of connectivity, as it provides direct access to applications and resources without the need for a VPN tunnel.
• ZTNA provides a more efficient and secure way of accessing cloud-based resources compared to traditional VPNs.

Explore the concept of Zero Trust Network Access (ZTNA) which revolutionizes the traditional VPN model by allowing users to connect directly to applications through access proxies or brokers. Learn about how ZTNA follows the zero-trust principle of continuously monitoring user authentication and access levels, and its lightweight nature compared to VPN.
