## Summary

This activity requests $13.5M in FY2027, 100% of project EMR-02, up 25% on FY2026. The R-2A exhibit describes it across FY2026–FY2027, including what the FY2027 money is planned to buy.

## What the FY2027 request buys

**FY2027 planned work.** - Produce final processor designs and performance models for enforcing code compartmentalization policies. - Develop enhanced attack campaign test cases for DoW-relevant applications. - Apply compartmentalization and privilege management tools and processor enforcement mechanism to an application nominated by a DoW partner.

**FY2026 to FY2027 change.** The FY 2027 increase reflects continued development of compartmentalization techniques and additional work to test and demonstrate compartmentalization on military systems.

## Before the request year

**FY2026 plans — current year.** - Produce code compartmentalization and processor and policy enforcement implementations. - Develop initial attack campaign test cases for Department of War (DoW)-relevant applications. - Evaluate effectiveness and overhead of compartmentalization and privilege management systems using operating system attack campaign test cases.

## Funding

| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2026 | Enacted | 10.8 |
| FY2027 | Request | 13.5 |

> Prior, current and budget year only — an R-2A activity carries no five-year plan. It sums exactly into its project in the request year and not necessarily in any other.
