The price of failure is high an incorrect or incomplete configuration can leave security gaps in the system. Admins can create additional policies, but to create correct, effective, and comprehensive rulesets, admins need deep expertise in both web security and the AWS ecosystem. Limitation: Rule AdministrationĪlthough AWS WAF includes some prebuilt policies, they have limited scope. However, this feature set also highlights one of AWS WAF’s most significant problems the fact that users need to develop their own rules. Request size could be used to filter out malicious payloads or unexpected content. For instance, string/regex match can be used to look for arbitrary headers or values present in request metadata. These features give users a fairly capable toolkit to start developing their own rules. Detection of malicious SQL code or scripting.Size of a particular part of the request.String match or regular expression (regex) match in a part of the request.Part 1 of this series briefly covered the high-level traffic filtering features offered by AWS WAF: ACLs are then applied to specific resources that the end user wishes to protect. These rules are aggregated in a web access control list (web ACL). A good WAF doesn’t just block traffic, however it needs to be equally flexible in letting valid traffic pass.ĪWS WAF uses rule statements to define specific filtering criteria and behavior. A web application firewall must be able to inspect this traffic and immediately make accurate filtering decisions. Modern web traffic is dense and complex, and attackers have a wide variety of potential attack vectors to exploit. Discuss how to effectively protect sites, applications, and APIs running on Amazon Web Services.Highlight its limitations, some of which are significant.Explore AWS WAF in terms of its traffic filtering, monitoring and reporting, bot management, ATO prevention, API security, and cost structure.Now in this final article in the series, we will: In Part 2, we discussed AWS WAF and the OWASP Top 10 risks. In Part 1 of this series, we went through an overview of AWS WAF’s capabilities. In this article series, we’re taking a deep dive into this important tool. AWS WAF is the foundation for most of the native security capabilities within Amazon Web Services.
