How do rate limiting techniques help in bot mitigation?

Rate limiting techniques help in reducing the impact of bot attacks by limiting the number of requests a bot can make to a website or server within a certain time frame. This helps in preventing the server from being overwhelmed by a high volume of requests from malicious bots, thus protecting the website from slowdowns or crashes caused by a DDoS (Distributed Denial of Service) attack. By setting limits on the rate at which requests can be made, legitimate users are still able to access the website while suspicious or excessive activity from bots is restricted, enhancing overall security and performance.
