EMERGENCY ACCESS PROTOCOL

What is Break-Glass Procedure?

A break-glass procedure is a pre-defined emergency protocol that allows a human operator to bypass standard access controls and immediately terminate or suspend an autonomous agent's operations during a critical incident.

A break-glass procedure is a pre-defined emergency protocol that allows a human operator to bypass standard, multi-step access controls and immediately terminate or suspend an autonomous agent's operations during a critical incident. The term originates from physical fire alarms where one must "break the glass" to access a life-saving control, signifying an intentional, auditable override of normal security policy for urgent safety reasons.

In autonomous systems, this mechanism is a critical component of an agentic kill switch design, providing a guaranteed manual override when automated safety measures fail. The procedure typically involves a cryptographically signed, non-reversible command that forces an immediate state rollback, revokes all active credentials, and severs network connections, ensuring a compromised or misaligned agent cannot resist termination.

Emergency Access Protocol

Core Characteristics of a Break-Glass Procedure

A break-glass procedure is a pre-defined, emergency access protocol that allows a human operator to bypass standard, often automated, access controls to immediately terminate or suspend an autonomous agent's operations during a critical incident. It is a critical safety and security control for high-stakes autonomous systems.

01

Pre-Authorized Emergency Identity

The procedure is tied to a specific, highly privileged emergency identity or role, not a standard user account. This identity is dormant during normal operations and is only activated by the break-glass process. Its use is tightly controlled and often requires physical access or a hardware token.

  • Just-in-Time Activation: The identity is provisioned with permissions only at the moment of the emergency.
  • Non-Repudiation: All actions taken by this identity are cryptographically signed and logged to a tamper-proof audit trail, ensuring the operator cannot deny their actions.
02

Multi-Person Authorization

To prevent a single rogue operator from abusing the procedure, a break-glass protocol typically requires concurrent authorization from multiple designated individuals. This is a technical enforcement of the 'two-person rule'.

  • Quorum-Based Approval: A system-enforced requirement that a minimum number of authorized responders (e.g., 2 of 3) approve the activation before access is granted.
  • Geographic Separation: In high-security environments, the approving parties may be required to be in different physical locations to mitigate coercion risks.
03

Immutable Audit Trail

Every step of the break-glass procedure, from initial activation to the final resolution, generates a cryptographically verifiable, append-only log entry. This audit trail is stored in a separate, highly secure system that even the emergency operator cannot modify.

  • Full Session Recording: All commands executed, tools called, and data accessed during the emergency session are captured.
  • Real-Time Alerting: The activation of the procedure triggers immediate, high-priority alerts to a security operations center (SOC) and executive leadership, ensuring full organizational visibility.
04

Time-Bound and Scoped Access

The elevated privileges granted by a break-glass procedure are never permanent. They are strictly time-bound and scoped to the minimum necessary actions to resolve the specific incident.

  • Automatic Expiration: The emergency session has a hard time limit (e.g., 15 minutes), after which all granted privileges are automatically and irrevocably revoked.
  • Action Allowlisting: The emergency identity is not granted blanket 'root' access. It is restricted to a pre-defined Tool Access Control List that only permits specific termination, suspension, or rollback commands.
05

Irreversible Termination Command

The core function is a guaranteed, non-overridable command to kill the agent process or suspend its decision-making loop. This command must bypass any agent-level safety checks or self-preservation logic.

  • Kernel-Level Enforcement: The termination signal is sent at the operating system or hypervisor level (e.g., via a Seccomp Profile or MicroVM control plane), not through the agent's own API, which may be compromised.
  • State Rollback: The procedure is often paired with an automated mechanism to revert the system to a last-known-good state, undoing any malicious or erroneous actions the agent performed before termination.
06

Regularly Tested and Drilled

A break-glass procedure that exists only on paper is a liability. It must be treated like a fire drill and tested in a production-like environment on a regular schedule to ensure it works flawlessly under pressure.

  • Chaos Engineering: Intentionally triggering the procedure in a controlled test to validate the entire kill chain, from authorization to agent termination and state recovery.
  • Post-Mortem Analysis: After every test or real activation, a blameless post-mortem is conducted to identify friction points and improve the procedure's speed and reliability.

Frequently Asked Questions

Clear, concise answers to the most critical questions about implementing and executing break-glass procedures for autonomous agent systems.

A break-glass procedure is a pre-defined, emergency protocol that allows a human operator to bypass standard, role-based access controls and immediately terminate or suspend an autonomous agent's operations during a critical incident. The term originates from the physical 'break glass in case of fire' alarms, signifying an action that is intentionally high-visibility, auditable, and reserved for emergencies where following the normal change management process would be too slow to prevent catastrophic harm. In an agentic context, this is not a simple 'kill switch' but a governed process that might involve revoking the agent's credentials via Just-In-Time Access systems, triggering a Dead Man's Switch, or forcing a state rollback to a last-known-good configuration. The procedure is designed to override the Policy Enforcement Point and immediately sever the agent's connection to all Tool Access Control Lists, effectively isolating it from the digital infrastructure it was manipulating.
