CISA Releases Guidance to Assist Agencies Moving From Wide Network Perimeters to Micro-Perimeters
The Cybersecurity and Infrastructure Security Agency (CISA) released a new Trusted Internet Connections (TIC) 3.0 draft guidance that adjusts to federal agencies narrowing their cyberdefenses.
The guidance was developed to assist agencies in protecting modern information technology architectures and services, less focused on a perimeter. According to CISA, in the early 2000’s, the White House Office of Management and Budget initiated a data-call asking federal agencies to inventory their connections to the internet. "The results were eye-opening: agencies reported more than 4,000 connections. This prompted a desire for network consolidation across the Federal Government in order to limit the number of tubes to monitor to a smaller set, spurring the initiative known today as Trusted Internet Connections (TIC)," says CISA.
