Abstract: A technology to identify processing paths of untrusted input data received by applications that are vulnerable to attacks and to further detect and prevent actual attacks that try to exploit those vulnerabilities is disclosed. Application code is augmented at run-time with sensor code which detects the entry of input-data into the application and further traces the propagation, manipulation and, sanitization of this input-data until its usage in a data sink. The so generated data-flow traces reveal data-flow paths that lack required sanitization measures to neutralize potentially harmful input-data. Such data-flow paths are reported as vulnerabilities. Further, input-data that reaches data-sink interfaces is scanned by data-sink sensors to identify harmful input data. On identification of harmful input data, an attack is reported, and countermeasures are applied to prevent the identified attack.

Abstract: A technology is disclosed to perform real-time and online identification and prioritization of vulnerabilities of components of software applications. Agents are deployed to components of monitored applications that monitor and report application topology, communication, code execution and code loading activity. Reported code loading and execution activity data is used to detect the loading and execution of vulnerable code, topology and communication data is used to create a topology model of the application containing communication paths, trust boundaries and location of sensitive data. The analysis of code loading and execution data reveals the extend to which vulnerable code is used by monitored application components. The topology data combined with code execution data reveals the extent to which components executing vulnerable code are exposed to untrusted entities and/or accessing sensitive data.
