Security interest
（重定向自Security devices）
A security interest is a property interest created by agreement or by operation of law over assets to secure the performance of an obligation, usually the payment of a debt. It gives the beneficiary of the security interest certain preferential rights in the disposition of secured assets. Such rights vary according to the type of security interest, but in most cases, a holder of the security interest is entitled to seize, and usually sell, the property to discharge the debt that the security interest secures.
