IrM

IRM is an acronym used in several fields and can refer to different concepts depending on the context. Common meanings include Information Rights Management, Incident Response Management, Internal Revenue Manual, and the Institute of Risk Management.

Information Rights Management (IRM) refers to technologies and practices that protect digital information from unauthorized access or use. IRM typically embeds encryption and policy-based controls in documents or services to govern viewing, editing, printing, copying, or forwarding, even after content leaves the creator’s environment. Implementations often integrate with data classification and protection platforms to maintain persistent safeguards across devices and cloud storage.

Incident Response Management covers organization-wide processes for detecting, analyzing, containing, eradicating, and recovering from security incidents. A mature program defines roles, runbooks, and communication plans, supports evidence handling, and conducts post‑incident reviews to improve readiness.

Internal Revenue Manual is a guide used by the United States Internal Revenue Service to document procedures for tax administration, enforcement, and appeals. It covers examinations, collections, and penalties, and provides guidance to ensure consistent decision making. Portions of the manual are publicly accessible as reference material.

The Institute of Risk Management (IRM) is a professional body based in the United Kingdom that provides training, standards, and certifications for risk professionals and offers guidance on risk governance, assessment, monitoring, and reporting.
