Understanding Discretionary Access Control in Zero Trust Network Access

Technology managers seeking robust security frameworks often turn to Zero Trust Network Access (ZTNA) to safeguard their IT environments. This post will explore how Discretionary Access Control (DAC) integrates with ZTNA, why it matters, and how it can enhance your security strategy.

What is Discretionary Access Control?

Discretionary Access Control is a system where the owner of a data resource decides who can access it. In DAC, permissions are not fixed, allowing users to grant access to others based on personal discretion. This flexibility offers fine-tuned control over who can view or modify data.

Why Pair DAC with ZTNA?

Both DAC and ZTNA focus on minimizing risk by controlling access based on identity. While DAC allows resource owners to specify who can access data, ZTNA ensures that access is granted based on verified trust, regardless of the network location. The fusion of these systems strengthens your security posture by:

• Reducing Insider Threats: By controlling who can see and share sensitive data, businesses can decrease the risk of internal leaks or unauthorized access.
• Enhancing External Security: ZTNA adds a layer of verification, ensuring only trusted users access network resources.

Implementing DAC in Your ZTNA Strategy

To leverage DAC within a ZTNA framework, follow these actionable steps:

1. Identify Key Resources: Determine which data resources are most sensitive and require discretionary access.
2. Set Clear Permissions: Document who should access each resource and regularly review and update permissions as roles change.
3. Integrate with ZTNA Tools: Choose a ZTNA tool compatible with DAC mechanisms to ensure seamless control and access verification.
4. Continuous Monitoring: Implement continuous auditing for access requests and approvals to spot any unusual patterns.

Why It Matters

Using DAC with ZTNA ensures technology managers maintain control over who can access critical resources while leveraging the assurance of identity verification. This combined approach addresses both internal and external threats, delivering a more comprehensive security solution.
