How the Redjack Cyber Resilience Platform Enables Zero Trust

Zero trust is an approach to cybersecurity that assumes no entity, whether inside or outside the network perimeter, can be trusted by default. It emphasizes continuous verification and strict access controls to protect against internal and external threats.

Having an accurate asset inventory is essential to implementing a zero trust security model as it forms the basis for granular access controls and least privilege principles. Without knowing what assets exist within the network, it's impossible to enforce strict access policies and segment resources effectively. By maintaining a comprehensive asset inventory, organizations can confidently apply zero trust principles, ensuring that only authorized users and devices have access to specific resources based on continuous authentication and contextual factors.

The Redjack cyber resilience platform plays a crucial role in implementing zero trust. It provides essential visibility and context through asset discovery, critical business function identification, and dependency mapping. This is necessary to effectively implement the "never trust, always verify" zero trust approach. 

Asset Visibility and Inventory

Asset discovery uses communications data to create an up-to-date inventory of all devices, applications, and data that are communicating within the organization’s network. This includes endpoints, servers, cloud resources, applications, and databases as well as any third-party assets that are communicating with assets within your environment. The comprehensive visibility provided by the Redjack cyber resilience platform is essential for implementing adequate access controls. 

Risk Assessment and Segmentation

By identifying your critical business functions, identifying those assets that they rely on, and mapping the dependencies between your assets, your organization is better able to assess the risk associated with each asset and apply appropriate security measures accordingly. The Redjack cyber resilience platform categorizes assets based on sensitivity and criticality, allowing for better segmentation and micro-segmentation strategies as part of the zero trust approach.

Context-Aware Access Control

Zero trust requires making access decisions based on context, such as user identity, device health, location, and behavior. An asset inventory provides you with the context you need to enforce adaptive access controls. For example, a sensitive database may only be accessible from specific authorized devices and locations. 

Continuous Monitoring

Redjack’s sensors continuously update your asset inventory, facilitating continuous monitoring of assets and their interactions, enabling real-time threat detection and response. Any changes in asset behavior or access patterns can be quickly identified, helping to prevent unauthorized access or lateral movement by attackers. 

Security Policy Enforcement

Zero trust relies on strict security policies to control resource access. The Redjack cyber resilience platform assists in defining and enforcing these policies by providing a clear understanding of asset relationships and the dependencies between them.

Identifying Shadow IT

The Redjack cyber resilience platform uses communications data-enabled asset discovery to locate all assets in your environment, including shadow IT resources that the IT and security teams do not know about. This is important as unmanaged and unsecured assets can pose security risks and undermine zero trust strategies.

Data Protection and Encryption

The Redjack cyber resilience platform assists in locating and identifying critical data assets, enabling organizations to prioritize data protection efforts and implement appropriate encryption measures. 

In summary, the Redjack cyber resilience platform provides you with the foundation you need to implement zero trust security. It gives you comprehensive visibility into your IT environment, discovering and identifying all assets and their relationships. This visibility enables you to enforce a zero trust model effectively, reducing your attack surface and improving overall security posture.
