4 Security Controls of a Zero Trust Network

Zero trust may be a simple concept, but its architecture is complicated. Zero-trust networks are designed to keep the data transmitted between computers safe. They combine multi-factor authentication, smart data segregation, and Identity-based validation policies. These security controls provide a strong foundation to prevent a network from being hacked. 

Multi-Factor Authentication

Multi-factor authentication is a critical security component for Zero Trust networks. A Zero Trust architecture ensures that only authorized users can enter the network. Zero trust architectures require continuous monitoring of user access and activity. Multi-factor authentication in zero-trust network access enables users to authenticate themselves before they enter the system.

As organizations increasingly digitize their operations, they take on more responsibility for securing customer data. This information is a prime target for attackers. Because of this, confirming the identity of a user is more important than ever. However, traditional usernames and passwords provide unreliable and unwieldy authentication. Users also find it difficult to manage the number of passwords on multiple accounts. They also tend to reuse passwords across services. In addition to multi-factor authentication, Zero Trust Networks also require comprehensive visibility of user devices and activity. 

Smart Data Segregation

Smart data segregation is a key part of a Zero trust network. It enables companies to secure data from unauthorized users. Smart data separation is achieved using a multi-factor authentication strategy beyond passwords. This includes biometric verification. It also incorporates strong user identification policies, making the network more secure and protecting sensitive data.

Zero-trust networks require continuous monitoring and analysis to identify and stop malicious activities. These tools also allow organizations to quickly and easily enforce regulatory compliance. Today, 53% of organizations report a shortage of cybersecurity specialists. By utilizing a Zero Trust model, organizations can reduce the operational complexity of their security teams and dramatically improve their work efficiency.

Identity-Based Validation Policies

Identity-based validation policies are an important aspect of identity security and an element of a Zero Trust network. These policies use dynamic data analysis to verify the identity of users and other entities connecting to the network. These policies should only grant authorization to users and systems that need it.

Zero Trust is a security approach that reduces the risks associated with implicit trust. This approach ensures that users can access only the resources and business applications necessary for their job. It also enforces secure access controls when a user tries to access an enterprise resource. Identity-based zero-trust networks can be implemented by implementing network segmentation rules and risk-based authentication policies. These security solutions can offer higher granularity and risk detection capabilities than other user authentication methods. The idea is to assume that a user account is compromised until proven otherwise. If a user account has been compromised, it can move laterally across the network and access any resource.

Layered Security Controls

Layered security controls are an integral part of a Zero trust network. These controls help to keep an organization’s data secure. This approach is based on the principle of least privilege, which requires strict account policies. For example, service accounts should be known and should only be given limited connection privileges. Overly-permissive service accounts allow lateral movement and enable attackers to gain access to domain controllers or authentication systems. 

A Zero Trust network requires strict identity verification for both users and devices. This eliminates the risk of lost customer trust and limits the potential damage of a breach. It also reduces the complexity of the security stack by eliminating redundant security devices. Zero trust security requires a strong encryption system and a comprehensive identity verification strategy. Generally, a Zero Trust network requires two main layers: the control plane and the data plane. The control plane is where requests for protected resources come from. Users and devices need to be authenticated to access more sensitive resources. The control plane is also the layer for fine-grained policy.
