Bot Mitigation

Advanced Mitigation Measures

Currently, there are three technical approaches to detecting and mitigating bad bots. They are:

• Static approach: These tools can identify web requests and header information. Then it will correlate with bad bots, passively determining the bot’s identity, and blocking it if required.

• Challenge-based approach: This would make the website to proactively check if traffic originates from human users or bots. These kind of bot detectors can check each visitor’s ability to use cookies, run JavaScript, and interact with CAPTCHA elements. Minimal ability to process these kind of elements is a hint of bot traffic.

• Behavioral approach: This mechanism looks at the behavioral signature of each visitor and see if it is what it claims to be. This approach establishes a baseline of normal behavior for user agents like Google Chrome, and sees if the current user deviates from that behavior. It can also compare behavioral signatures to previous, known signatures of bad bots.
