THE US Cybersecurity and Infrastructure Security Agency (CISA) has released new guidance to assist federal agencies in transitioning from legacy internet gateways to Secure Access Service Edge (SASE) technology as they adopt a zero trust model. This guidance addresses the shift from the perimeter-based Trusted Internet Connections (TIC) 2.0 to the more flexible TIC 3.0 approach, allowing for distributed network architectures while maintaining visibility through CISA’s telemetry systems.
SASE integrates networking and security functions into a mostly cloud-based solution. Agencies must provide equivalent data to CISA’s Comprehensive Log Aggregation Warehouse (CLAW) to retain visibility as traffic is no longer routed through central gateways. The guidance intends to help federal agencies enhance their cybersecurity strategies by promoting a structured approach to zero trust architectures.
