Terminology · 20
term

Incident Command

Assigning explicit roles during an incident — commander, operations lead, communications lead, scribe — so coordination does not compete with diagnosis.

Reliability & Resilience
term

Blameless Postmortem

An incident review that seeks the systemic conditions that made a failure possible, explicitly excluding individual fault.

Reliability & Resilience
term

Severity Levels

A predefined scale of incident impact that determines who is woken, how fast, and what process applies.

Reliability & Resilience
term

Application Portfolio Management

Maintaining an inventory of every application with its owner, cost, business value and technical health, and using it to decide what to invest in, replace or retire.

Enterprise Architecture
term

Consent Management

Capturing, storing, honouring and evidencing a data subject's permissions for specific processing purposes, including withdrawal.

Privacy Engineering
term

Global Traffic Management

The layer that decides which region a given user reaches, using DNS, anycast or an edge network, and that performs regional failover.

Multi-Region Architecture
term

Identity and Access Management

The system of record for principals, credentials and permissions, and the policy engine that decides what each principal may do.

Security Architecture
term

Offset Management

How a consumer records its position in a stream, and the decision that determines whether processing is at-least-once or at-most-once.

Event Streaming
term

Secrets Management

Storing, distributing, rotating and auditing credentials so that they never live in code, images or configuration files.

Security Architecture
term

Chaos Engineering

Deliberately injecting failure into a system to discover, before an incident does, which of your resilience assumptions are false.

Reliability & Resilience
term

Containment vs Eradication

Stopping an attacker's ongoing access versus removing their foothold entirely — sequential phases with different urgency and different risks of doing them wrong.

Security Incident Response
term

Dwell Time

The period between an attacker gaining access and being detected — the metric that determines how much damage an intrusion can do.

Security Incident Response
term

Dynamic Secrets

Credentials generated on demand for a specific consumer with a short lease, rather than stored, shared and rotated periodically.

Secrets Management
term

Envelope Encryption

Encrypting data with a locally-generated data key, then encrypting that key with a master key held in a key management service, and storing the wrapped key alongside the ciphertext.

Encryption
term

Hardware Security Module

A tamper-resistant device that generates and stores keys and performs cryptographic operations without the key material ever being extractable.

Key Management
term

Key Rotation

Periodically replacing a cryptographic key with a new one while retaining the old for decrypting existing data, so exposure from any single key is bounded.

Key Management
term

Permission Boundary

A policy limiting the maximum permissions an identity can have, used so that the ability to create roles does not become the ability to grant unlimited privilege.

Identity & Access Management
term

Prompt Registry

A versioned store of production prompts with their model bindings, parameters and evaluation results, so a prompt change is a reviewable, traceable, reversible deployment.

AI-Era Architecture
term

Secret Zero

The credential a workload needs in order to authenticate to the secret manager — the one secret that cannot itself be stored in the secret manager.

Secrets Management
term

Workload Identity

Giving a running workload a cryptographically verifiable identity issued by the platform, so it obtains short-lived credentials without a stored secret.
