What are the challenges in protecting against bots that use distributed networks?

One major challenge in protecting against bots that use distributed networks, such as botnets, is that they can evade detection by spreading their activities over a large number of computers or devices, making it difficult to pinpoint and block them accurately. Additionally, botnets can coordinate attacks from multiple sources simultaneously, overwhelming traditional security measures. Defending against botnets requires sophisticated strategies that can identify and block coordinated malicious activities across a network without disrupting legitimate traffic.
