# Security and operating controls

TaaS includes operational security controls at the tokenization layer.

**These controls can include:**

· independent smart contract audits;

· MPC custody or approved custody workflows;

· threat monitoring;

· subscription and redemption pausing;

· access-control reviews;

· role-based permissions;

· oracle deviation checks;

· co-signer systems;

· service-provider verification;

· collateralization monitoring;

· product-level status flags.

The goal is to make tokenized yield products safer to operate at scale. Tokenization increases distribution surface area, so the control framework must grow with it.
