From there, we walk edges backwards until we reach the method node using inAstMinusLeaf.

In computer science, a code property graph (CPG) is a computer program representation that captures syntactic structure, control flow, and data dependencies in a property graph. The concept was originally introduced to identify security vulnerabilities in C and C++ system code, but has since … See more A code property graph of a program is a graph representation of the program obtained by merging its abstract syntax trees (AST), control-flow graphs (CFG) and program dependence graphs (PDG) at statement and … See more Joern CPG. The original code property graph was implemented for C/C++ in 2013 at University of Göttingen as part of the open-source code analysis tool Joern. This original version has been discontinued and superseded by the open-source Joern … See more Consider the function of a C program: The code property graph of the function is obtained by merging its abstract syntax tree, control-flow graph, and program dependence graph at statements and predicates as seen in the following figure: See more Code property graphs provide the basis for several machine-learning-based approaches to vulnerability discovery. In particular, See more • Abstract syntax tree (AST) • Control-flow graph (CFG) • Program dependence graph (PDG) • Graph database See more WebThe code property graph created by Joern matches that of the code property graph as described in the paper and merely introduces some additional nodes and edges that have turned out to be convenient in practice. Code Property Graphs ¶ For each function of the code base, the database stores a code property graph consisting of the following nodes. WebA property graph is composed of the following building blocks: Nodes and their types. Nodes represent program constructs. This includes low-level language constructs such as … japan needs tech workers india has them
