Abstract

Aspects of the present disclosure involve systems, methods, computer program products, and the like, for utilizing an access log of a proxy server device of a content delivery network (CDN) to detect and mitigate a denial of service (DOS) on a web or content server hosted by the CDN. Through an analysis of the content requests received at the proxy server listed in the access logs, one or more IP addresses may be identified as involved in a potential DOS attack or other suspicious behavior. Once identified, the suspicious activities of the one or more IP addresses may be tracked and aggregated over a particular period of time, with each detected suspicious request to the content server being counted. The count of suspicious requests to the content server may then be compared to one or more threshold values and a remediation action may occur when the thresholds are met or exceeded.
