Need and Impact of Deployment
Evolution of Domestic Security Policies
(Security Policies and Guidelines)
(Security Policies and Guidelines)
Traditional network segmentation policies face structural limitations in connecting with external systems such as AI and SaaS. To address this, the government has introduced the National Network Security Framework (N2SF).
Under the N2SF model, the use of Cross Domain Solutions (CDS) is recommended when connectivity between business networks and the Internet is required.
This enables secure adoption of AI and cloud-based services while maintaining strict security controls for data access and transfer across domains.
