Defense in Depth
A classic principle in security engineering in which multiple independent layers of security controls are stacked so that the compromise of any single layer is insufficient to cause total system failure. It is widely applied in information security and in AI agent system architecture.

The defensive value of the deadly triad framework lies in the fact that reliably eliminating any one of the three legs breaks the attack chain, which is consistent with the defense-in-depth concept in cybersecurity.
Implementing SSRF protection uniformly at the core layer embodies the Defense in Depth principle, offering better security coverage and consistency than a perimeter security mindset.
For high-risk operations such as payments and permission changes, relying on a single Fail Open gateway does not conform to the Defense in Depth principle; it is recommended to layer in-tool validation or human approval on top.
Defense in Depth refers to deploying multiple independent layers of security controls so that an attacker must breach every layer before causing substantive damage
In Agent security, model alignment is the first layer of protection, behavioral constraints in system prompts are the second layer, and interceptors at the system call layer are the last hard line of defense
