ZTNA

Can anyone share a guide for configuring Zero Trust Network Access?

Hi,

Zero Trust Network Access (ZTNA), covering the followingsolutions:

ZTNA access proxy

HTTPS and TCP access proxy solution and architecture

Applies to both remote access and internal access to the internal network

No persistent connection (such as VPN) is necessary

ZTNA secure access

Remote users continue to access the internal network by using VPN, with additional layers of ZTNA deviceidentity and ZTNA posture checking provided by rules and tagging

Local users access the internal network through local access policies and ZTNA posture checks

Using a similar scenario and topology example from the ZTNA Architecture Guide, we will walk through deploying thecore components by providing configuration examples to help you migrate from dial-up VPN to ZTNA access proxy forremote users and ZTNA secure access for local users and those that still require VPN.The goal is to reduce the reliance on dial-up VPN by adding device authentication with role-based application access.We will focus on the services located at head quarters (HQ) along with remote users currently using dial-up VPN.Concepts from this deployment guide can be applied to regional offices and even cloud datacenters.

Thanks

I think Sangfor NGAF has no solutions yet for ZTNA but it is included in their roadmap

1) Assess your network and identify assets to protect.
2) Define access policies based on user roles, device posture, and location.
3) Implement strong authentication mechanisms like multi-factor authentication (MFA).
4) Set up secure remote access using VPN or software-defined perimeter (SDP) solutions.
5) Segment your network into smaller, isolated segments.
6) Grant users the minimum necessary privileges (least privilege principle).
7) Deploy network monitoring tools and utilize analytics for threat detection.
8) Regularly review and update security policies.

Here's a high-level guide for configuring Zero Trust Network Access (ZTNA):

• Define Access Policies:

  
  
  Identify the applications, services, and resources that need to be protected.
  Determine the specific access requirements for each resource based on user roles, device types, and contextual factors.
• Implement Identity and Access Management:

  
  
  Deploy a centralized identity management system such as a directory service or identity provider.
  Ensure strong authentication mechanisms like multi-factor authentication (MFA) are enforced.
  Implement user and device identity verification to establish trust before granting access.
• Secure Endpoint Devices:

  
  
  Enforce security measures on endpoints, including up-to-date patches, antivirus software, and secure configurations.
  Implement device health checks to ensure compliance with security policies before granting access.
• Implement Network Micro-Segmentation:

  
  
  Segment the network into smaller trust zones and enforce strict access controls between them.
  Utilize network virtualization technologies like virtual LANs (VLANs), virtual private networks (VPNs), or software-defined networking (SDN) to create isolated network segments.
• Apply Granular Access Controls:

  
  
  Implement a secure access gateway or software-defined perimeter (SDP) solution to provide fine-grained access control to resources.
  Use technologies such as software-defined perimeters, virtual private networks (VPNs), or software-defined wide area networks (SD-WAN) to create secure connections.
• Monitor and Analyze Traffic:

  
  
  Deploy real-time monitoring and analytics tools to detect anomalies, threats, and unauthorized access attempts.
  Utilize behavior-based analysis and machine learning to identify patterns and potential security incidents.
• Regularly Update and Patch Systems:

  
  
  Maintain a regular patching and update schedule for all systems and applications to address security vulnerabilities promptly.
• Continuous Security Assessments:

  
  
  Conduct regular security assessments, penetration testing, and vulnerability scanning to identify potential weaknesses.
  Implement continuous monitoring and threat intelligence to stay updated on emerging threats.
