Abstract: System, method and computer program product for detecting a denial of service attack on a plurality of computers. Records are made of source IP addresses of requests sent to each of the computers. The records of requests sent to the plurality of computers are totalled per source IP address and/or per range of source IP addresses. A determination is made if the total for a source IP address and/or range of source IP addresses exceeds a respective, predetermined threshold. If so, a denial of service attack is suspected or determined, and a firewall can be notified to block subsequent requests from the source IP address and/or range of source IP addresses, and an administrator can be notified to investigate the situation. Records can also be made of requests sent to each of the computers for a file or access to an application. These records of requests sent to the plurality of computers are totalled per file or application access.
