Improper configuration of resources and rate limiting can lead to attackers being able to overload a system with re``quests, causing APIs to fail or become unresponsive. Rate and resource limiting are measures that can be taken to help mitigate this risk. It involves limiting the number of requests that a user can make in a given period of time. This can prevent attackers from being able to send a large number of requests and overwhelm the system.
