The DoD Defense Industrial Base (DIB) Collaborative Information Sharing Environment (DCISE) serves as the single DoD focal point for receiving all cyber incident reporting affecting unclassified networks of DoD contractors from industry and other government agencies.

DCISE Overview

DCISE also serves as the operational focal point for the voluntary Defense Industrial Base Cybersecurity (CS) Program under 32 Code of Federal Regulations part 236 designed to enhance and supplement DIB participants’ capabilities to safeguard DoD information that resides on or transits, DIB unclassified information systems. DCISE fosters a cyber threat information sharing partnership with DIB participants by performing cyber analysis, offering mitigation and remediation strategies, providing best practices and conducting analyst-to-analyst exchanges with DIB participants.

Effective April 2019, DCISE is rated at Maturity Level 3 for the Capability Maturity Model for Services (CMMI-SVC).
