  • Automatic generation of patches for security violations
    Patent number: 12182269
    Abstract: Aspects of the disclosure provide for automatically generating patches for security violations. For example, a plurality of inputs may be generated for code. The code may be executed using the plurality of inputs to obtain execution states at a plurality of code locations. The execution states may include at least one security violation for at least some of the plurality of inputs. Using the execution states, one or more patch conditions causing the at least one security violation may be determined. Using the execution states, one or more corresponding patch locations may be determined based on a code location of the plurality of code locations where the at least one security violation each of the one or more patch conditions occurred. At least one candidate patch for the at least one security violation may be automatically generated. The at least one candidate patch may include one of the patch conditions and one of the corresponding patch locations.

  • Differential dependency tracking for attack forensics
    Patent number: 9736173
    Abstract: Methods and systems for intrusion attack recovery include monitoring two or more hosts in a network to generate audit logs of system events. One or more dependency graphs (DGraphs) is generated based on the audit logs. A relevancy score for each edge of the DGraphs is determined. Irrelevant events from the DGraphs are pruned to generate a condensed backtracking graph. An origin is located by backtracking from an attack detection point in the condensed backtracking graph.
