Joint Regional Security Stacks (JRSS)

The Joint Regional Security Stacks (JRSS) program, managed by the Defense Information Systems Agency (DISA), aims to enhance the security architecture of the Department of Defense (DoD) networks. This initiative focuses on deploying a collection of hardware and software components designed to operate as a single unit, providing comprehensive defensive security solutions. The primary objectives include removing redundant information assurance protections, leveraging enterprise defensive capabilities, and protecting network enclaves after separating server and user assets. Additionally, JRSS provides essential tools for monitoring and controlling security mechanisms, supporting over 1.7 million DoD users worldwide.

In its Operations and Sustainment Phase, JRSS is committed to refreshing technology within the stacks to address critical end-of-life and end-of-support hardware and software dates. This involves maintaining support for a suite of components that detect and prevent security vulnerabilities within DoD networks. The program also aims to prevent isolation of military bases and maintain the authority to operate while ensuring compliance with U.S. Cyber Command directives. A significant goal is achieving cost reductions through planned decommissioning efforts and transitioning users off JRSS by FY 2027.

For FY 2023, the focus was on procuring hardware and software to support technology refresh enhancements, such as Full Packet Capture capabilities and Base Tier Firewalls with Remote Access Virtual Private Network. These procurements aimed to address functionality enhancements across 14 stacks within the JRSS architecture.

In FY 2024, efforts will continue for technology refresh updates, including Switch Fabric Devices essential for intra-stack connectivity and Enhancement 2 efforts for maintaining cybersecurity postures in operational stacks. Looking ahead to FY 2025, the program will continue procuring necessary hardware and software to support ongoing technology refresh updates. This includes further investments in Switch Fabric Devices and Enhancement 2 components critical for maintaining core functionality and security within the JRSS architecture.

The planned decrease in operational stacks aligns with the final decommissioning schedule approved by DoD Services, with an eventual sunset of JRSS capabilities anticipated by FY 2027.
