Meta Attack Pattern - A meta level attack pattern in CAPEC is a decidedly abstract characterization of a specific methodology or technique used in an attack. A meta attack pattern is often void of a specific technology or implementation and is meant to provide an understanding of a high level approach. A meta level attack pattern is a generalization of related group of standard level attack patterns. Meta level attack patterns are particularly useful for architecture and design level threat modeling exercises.
This type of an attack requires the ability to generate a large amount of HTTP traffic to send to a target server.
缓解
Design: Use a Web Application Firewall (WAF) to help filter out malicious traffic. This can be setup with rules to block IP addresses found in IP reputation databases, which contains lists of known bad IP addresses. Analysts should also monitor when the traffic flow becomes abnormally large, and be able to add on-the-fly rules to block malicious traffic. Special care should be taken to ensure low false positive rates in block rules and functionality should be implemented to allow a legitimate user to resume sending traffic if they have been blocked.
Hire a third party provider to implement a Web Application Firewall (WAF) for your application. Third party providers have dedicated resources and expertise that could allow them to update rules and prevent HTTP Floods very quickly.
设计：使用负载平衡器（例如NGINX）通过分散一组服务器之间的流量来防止小规模HTTP洪水。
Implementation: Make a requesting machine solve some kind of challenge before allowing them to send an HTTP request. This could be a captcha or something similar that works to deter bots.
Related Weaknesses
A Related Weakness relationship associates a weakness with this attack pattern. Each association implies a weakness that must exist for a given attack to be successful. If multiple weaknesses are associated with the attack pattern, then any of the weaknesses (but not necessarily all) may be present for the attack to be successful. Each related weakness is identified by a CWE identifier.

Taxonomy Mappings
CAPEC mappings to ATT&CK techniques leverage an inheritance model to streamline and minimize direct CAPEC/ATT&CK mappings. Inheritance of a mapping is indicated by text stating that the parent CAPEC has relevant ATT&CK mappings. Note that the ATT&CK Enterprise Framework does not use an inheritance model as part of the mapping to CAPEC.
