Setting Up Zero Trust Network for Remote Workers

How feasible is it to set up the ZTN to cover the remote worker locations and for the MSP to accomplish this task remotely?

It is technically possible to set up a Zero Trust Network (ZTN) to cover remote worker locations, and an MSP can accomplish most of the implementation remotely. The challenge lies in the system's design and management, but modern tools and strategies make it feasible.

Here’s how an MSP can set up a ZTN for remote workers remotely:

1. Remote Endpoint Enrollment: Each device (laptop, mobile, IoT, etc.) used by remote workers can be enrolled in the ZTN using Remote Monitoring and Management (RMM) software. This allows the MSP to push the necessary software and security policies to each device, ensuring that all endpoints are continuously monitored and authenticated before gaining access to the corporate network. The enrollment can be done entirely remotely, provided the device connects to the internet.

2. Software-Defined Perimeter (SDP): The use of SDPs in Zero Trust architecture allows the MSP to create secure, individualized network perimeters for remote workers. Through cloud-based control planes, the MSP can remotely configure network access, define policies, and monitor user activity without needing to be physically present at remote worker locations.

3. Multi-Factor Authentication (MFA) and Passkeys: The MSP can remotely enforce MFA and Passkey-based authentication. Using centralized management tools, the MSP can distribute and manage passkeys for employees, ensuring each remote worker's access is authenticated before allowing entry into the corporate network. This can be integrated with endpoint security tools, creating an additional layer of security that complies with ZTN principles.

4. Secure VPN and Network Access Control: Virtual Private Networks (VPNs) can be part of the zero-trust model to encrypt traffic for specific use cases. The MSP can configure secure VPN clients remotely, ensuring remote workers connect securely to corporate resources. Additionally, using Network Access Control (NAC) tools, the MSP can set rules to allow only authorized and compliant devices to access network resources remotely.

5. Cloud-Based Security Tools: ZTN relies heavily on cloud-based tools, such as identity and access management (IAM), endpoint detection and response (EDR), and threat intelligence platforms. These tools are cloud-native, meaning they can be deployed and managed remotely by the MSP. Once installed on remote devices, they continually enforce the Zero Trust policies without requiring on-site intervention.

Challenges to Consider:

• Employee Privacy Concerns: While the ZTN can cover remote worker locations, some employees may worry about intrusion into their personal networks. Careful communication about the ZTN's limits (i.e., it only protects corporate devices and data) is necessary to ensure workers understand that their home privacy is respected.
• Bandwidth and Connectivity: The effectiveness of ZTN for remote workers depends on stable internet connections. For workers in locations with poor connectivity, this could create performance or security enforcement issues.
• Initial Setup and Onboarding: While most ZTN components can be deployed remotely, some initial device configurations may require more direct involvement, particularly for workers unfamiliar with corporate IT systems. However, detailed remote onboarding support can often mitigate this.

Conclusion:

An MSP can implement a ZTN to cover remote worker locations remotely, thanks to cloud-based technologies, remote monitoring, and modern security frameworks. However, employee buy-in, clear communication about privacy, and stable connectivity will be key to its success.
