AWS WAF announces AWS Managed Rules (AMRs), a set of AWS WAF rules curated and maintained by the AWS Threat Research Team. With just a few clicks, AMRs can help protect your web applications from new and emerging threats, so you don’t need to spend time researching and writing your own rules. AMRs are based on common Internet threats, including security risks referenced in the OWASP Top 10 publication. AMRs also include IP reputation lists based on Amazon threat intelligence that can help reduce your exposure to bot traffic.
