Joint Information Environment (JIE)

The Joint Information Environment (JIE)/Joint Regional Security Stack (JRSS) is a joint Department of War (DoW) security architecture deployed regionally throughout the world. There are fourteen (14) Non-Secure Internet Protocol Router (NIPR) stacks, which are a collection of software components designed to operate as a single unit. DISA will achieve cost reductions through planned Decommissioning Efforts and user transition off of JRSS in accordance with the JRSS Senior Advisory Group-approved Decommissioning Plan. The current JRSS footprint will be reduced to nine at the end of FY 2025 before closeout of the remaining stacks in FY 2027. Each stack is comprised of complementary defensive security solutions that: • Streamline cybersecurity protections. • Leverage enterprise defensive capabilities with standardized security suites to protect against attacks that disrupt or cause damage to the network. • Protect the JRSS enclaves done on my end, waiting on requests after the separation. • Provide the tool sets necessary to monitor all security mechanisms throughout the network. The JRSS Management System (JMS) provides management and operational control capabilities for the JRSS. The JMS centralizes and enhances the management of JRSS components and achieve economies of scale. The JMS enables DoW Components to maintain Title 10 required management and visibility of IT security while providing high level visibility to U.S. Cyber Command (CYBERCOM). This is done by: • Providing centralized management of the JRSS. • Providing visibility and control over network transport and associated security systems. • Enabling the monitoring and analysis of data to determine the impact on current operations. This centralized capability allows standardization of policies, procedures, and configurations and allows for Cyber Operations to take proactive actions to ensure the uninterrupted availability and protection of information.
