Break-Glass Access
Break-glass access is an emergency procedure that lets an authorized person gain elevated access to a system when normal access methods fail or are insufficient during a critical situation. It works by bypassing the usual authorization controls, typically using specially designated high-privilege accounts that are held in reserve for such emergencies. The term draws its name from the idea of breaking the glass on a fire alarm: it is meant to be used only in genuine emergencies.
Break-glass access is a controlled form of privileged access invoked in emergency situations, in which a user with normally insufficient rights is granted elevated permissions to bypass standard authorization controls. Implementations commonly rely on pre-staged emergency accounts provisioned so they can be made available with reasonable administrative overhead. Break-glass is an information security control concerned with the availability of access during failure or emergency conditions; it is distinct from routine access provisioning and, because of its elevated risk, is generally paired with governance measures such as monitoring, logging, and after-the-fact review, though the specific controls and audit expectations depend on the implementing organization and applicable regime. This entry does not address the specific logging, retention, or review obligations that a given framework (for example HIPAA in a healthcare context) may impose, nor does it cover how break-glass interacts with data protection obligations, which vary by jurisdiction and system.
Why it matters
Break-glass access addresses a fundamental tension in access control: the same restrictions that protect a system during normal operation can become an obstacle when a genuine emergency demands rapid, elevated access. Without a pre-defined emergency procedure, responders may improvise workarounds under pressure, sharing credentials informally or disabling controls in ways that leave no reliable record. A break-glass mechanism gives organizations a sanctioned, bounded path to elevated access so that availability of access is preserved during failure or crisis conditions without abandoning oversight entirely.
The control matters precisely because it is high-risk by design. It intentionally bypasses the authorization controls that normally guard a system, which means a break-glass account, if misused or compromised, can provide an attacker or an insider with broad privileges. For this reason break-glass is generally paired with governance measures such as monitoring, logging, and after-the-fact review, so that any invocation can be scrutinized and justified. Accountability here depends on demonstrable evidence of who invoked the access, when, and why, rather than on the mere existence of a documented procedure.
The scope of what break-glass requires varies by regime and organization. In a healthcare context, for example, frameworks such as HIPAA may impose expectations around emergency access to critical systems containing electronic protected health information, but the specific logging, retention, and review obligations differ across regimes and implementations. Break-glass is an information security control focused on availability of access; it does not by itself resolve how emergency access interacts with data protection obligations, which vary by jurisdiction and system.
