Break-glass is a necessary evil, but most implementations are either uselessly slow or a compliance nightmare. If your PAM solution makes you choose between security and actually fixing the fire, you've already lost.
I'm looking at this from a K8s/cloud-native angle. You need instant, time-bound, highly-audited root/admin access, but the audit trail must be immutable and capture *everything*. The classic "vaulted account" with a manual checkout is a joke during a 3am meltdown.
How do you structure this without creating a blind spot? I'm thinking:
- A dedicated break-glass IAM role, gated behind an approval workflow *that can be auto-approved under specific, monitored alarm conditions*.
- JIT access with a maximum session lifetime (like 15 minutes). All session activity logged as a single, immutable audit stream, even if it spans multiple systems.
- The session must be fully isolated—no reusing existing credentials.
Something like this for a K8s cluster admin role (oversimplified, but you get the idea):
```yaml
apiVersion: infrastructure.cluster.x-k8s.io/v1beta1
kind: BreakGlassAccessTemplate
metadata:
name: cluster-firefighter
spec:
targetRole: cluster-admin
maxDuration: 900s
justificationRequired: true
activationTriggers:
- severity: critical
alarmName: "cluster-api-unavailable"
auditConfig:
sink: "s3://audit-logs/breakglass/"
immutable: true
captureStream: ["stdout", "stderr", "api_requests"]
```
Is anyone doing this in a way that doesn't suck? The audit log must be outside the blast radius of the incident itself. If the break-glass user can delete or tamper with their own audit trail, you're back to square one.
