Using TrueNAS in a Zero-trust Architecture


December 30, 2022

In today’s age of complex and sophisticated malware attacks, storage infrastructure where data resides is a high-value target for bad actors. To combat new and evolving threats, TrueNAS uses several layers of security and protection, including the ability to easily integrate into a zero-trust IT environment to mitigate risk.

A zero-trust architecture is a vital security model for businesses that assumes that all network traffic is untrusted and should be treated as such. In a zero-trust environment, access to resources is granted on a need-to-know basis, and all traffic is monitored and controlled through the use of advanced security measures. Blocking untrusted traffic makes it very difficult for attackers to gain access to sensitive data, as they must first pass through multiple security controls before they can reach their intended target.

TrueNAS is designed with data protection and zero-trust security in mind. By combining security features in TrueNAS with IT best practices, you can create a highly resilient and secure architecture for your organization. Here are the steps you can take to create a zero-trust IT architecture integrating TrueNAS to protect, store, and manage your data:

Identify Assets: First, identify all of the assets that you need to protect. This may include servers, storage systems, networks, and other critical infrastructure.

Define Your Perimeter: Once you have identified your assets, you need to define your security perimeter. This will determine which resources are considered “inside” the perimeter and which are “outside.”

Use Microsegmentation: Microsegmentation involves breaking your network into smaller segments and applying security controls to each segment. This can help prevent attackers from moving laterally within your network and limit the damage they can do if they manage to gain access.

Implement Access Controls: TrueNAS allows you to set up fine-grained access controls for different users and groups and integrates with Active Directory / LDAP, so you can specify exactly who has access to which resources. This helps prevent unauthorized access to sensitive data and limits the damage that an attacker can do if they manage to gain access to a user account on your system.

Two-Factor Authentication (2FA): Using two-factor authentication (2FA) in TrueNAS adds another layer of security. By requiring administrators to provide additional authentication with their password, you keep the many settings on your TrueNAS safe.

Encrypted Connections and Data: TrueNAS utilizes encrypted connections using Secure Sockets Layer (SSL) and Transport Layer Security (TLS), so you can protect your data as it is transmitted over the network. This is especially important if you are storing sensitive data on your TrueNAS system.

TrueNAS also natively supports encrypted drives and datasets, providing additional security at the hardware and software levels respectively.

Monitoring, Auditing, and Analytics: TrueNAS includes several built-in tools for monitoring and auditing activity on the system. You can use these tools to keep track of who is accessing which resources and when and to identify any suspicious activity that might indicate an attempted breach.

Using TrueCommand, the single-pane-of-glass management solution for TrueNAS, you can set up additional features like role-based access control (RBAC) and robust auditing across your fleet to record all storage administration actions in secure audit logs. This helps quickly identify what changed and who changed it when troubleshooting any issues.TrueCommand analytics can be run locally, even on air-gapped systems, which are a requirement for many TrueNAS Enterprise customers.

TrueCommand is free to use for up to 50 drives, and commercial licenses can be purchased for larger deployments. For more information on TrueCommand, contact us or reach out to us through live chat.

Proactive Support: iXsystems offers proactive support with TrueNAS, allowing administrators to optionally send encrypted metadata to our expert TrueNAS Support Team. This gives extra peace of mind knowing that our storage experts will proactively reach out to you when certain errors are discovered.

By following these steps, you can create a zero-trust architecture and have the confidence to know that TrueNAS will help store and manage your data securely. Contact us or reach out to us through live chat to learn more about integrating TrueNAS into your business environment.
