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.
