Access Control
Rules and mechanisms that decide who or what can perform an action on a resource.
Motivation
Access Control matters because it gives teams a shared way to reason about rules and mechanisms that decide who or what can perform an action on a resource.
Where it fits
Access Control belongs to the software track and the Security layer. It is useful when teams need to connect design decisions to practical engineering work.
Mental model
Think of Access Control as a named pattern in the engineering map: it explains what problem is being solved, what boundaries are involved, and what tradeoffs appear when systems grow.
Common mistakes
- Treating the term as a buzzword instead of tying it to concrete behavior.
- Ignoring the operational, security, or product constraints around it.
- Learning the definition without knowing where it appears in real systems.
