Abstract: Vulnerability testing tasks can be received and distributed, via a work scheduler, to computer test environments. Each of the test environments can have a detector computing component running in the environment. Each detector component can respond to receiving one of the tasks from the work scheduler by conducting a vulnerability test on an endpoint of a target, detecting results of the vulnerability test, generating output indicating the results of the vulnerability test, and sending the output to an output processor. The work scheduler can initiate dynamic scaling of the test environments by activating and deactivating test environments in response to determining that the test environments are overloaded or underloaded, respectively. Also an overall time-based limit on testing for a target can be enforced via the work scheduler.

Abstract: To protect network-based services, offering computer implemented functionality, from attacks, a passive web application firewall reactively identifies vulnerabilities, enabling such vulnerabilities to be quickly ameliorated, without intercepting communications or introducing other suboptimal aspects of traditional web application firewalls. Communications directed to the network-based services are logged and such logs are scanned for entries evidencing attacks, such as based on predetermined attack syntax. Further evaluation of the entries identified as evidencing attacks identifies a subset of those entries that correspond to likely successful attacks. Such further evaluation includes attacking the network-based service in an equivalent manner. Attacks that are found to be successful identify vulnerabilities, and a notification of such vulnerabilities is provided to facilitate amelioration of such vulnerabilities.
