Mitigating against distributed denial of service (DDoS) attacks and brute force attacks is paramount for all businesses that operate online.
Rate limiting is a basic yet effective tool, limiting the number of requests from an IP address or authenticated user within a given time frame.
However, cyber attackers can bypass rate limits using various techniques, and when they do, they can access resources or orchestrate attacks without triggering alarms.
The key to effective rate limit bypass mitigation is understanding the common techniques that attackers use, such as IP spoofing, caching evasion, and header manipulation.
By understanding these techniques, firms can update their security practices and thoughtfully set rate limits to balance usability and security.
This includes differentiating between good and malicious traffic, deploying rate limiting at the edge of their network, and using multiple rate limiting methods.
When done well, businesses can effectively mitigate against common attack techniques, reduce overhead and keep their online services secure.
