Principle of Least Privilege

The principle of least privilege is a security concept that dictates that every module, user, or process must be able to access only the information and resources necessary for its legitimate purpose. In smart contract development, this means that functions should be restricted to the minimum required access level.

For example, a contract that manages treasury funds should not have the ability to modify the logic of a separate staking contract. By limiting permissions, developers reduce the potential attack surface and minimize the damage that can occur if a specific part of the system is compromised.

This principle is vital for preventing lateral movement within a protocol and ensuring that errors in one area do not affect the entire system. It is a cornerstone of defensive programming in decentralized environments.
