Static Analysis with CodeSonar

CodeSonar employs a unified dataflow and symbolic execution analysis that examines the computation of the complete application. By not relying on pattern matching or similar approximations, CodeSonar's static analysis engine is extraordinarily deep, finding 3-5 times more defects on average than other static analysis tools.

Unlike many software development tools, such as testing tools, compilers, configuration management, etc., SAST tools can be integrated into a team's development process at any time with ease. SAST technologies like CodeSonar simply attach to your existing build environments to add analysis information to your verification process.

How does static analysis work?

Like a compiler, CodeSonar does a build of your code using your existing build environment, but instead of creating object code, CodeSonar creates an abstract model of your entire program. From the derived model, CodeSonar’s symbolic execution engine explores program paths, reasoning about program variables and how they relate. Advanced theorem-proving technology prunes infeasible program paths from the exploration.

CodeSonar Static Code Analysis Representation

Checkers perform static code analysis to find common defects, violations of policies, etc. Checkers operate by traversing or querying the model, looking for particular properties or patterns that indicate defects. Sophisticated symbolic execution techniques explore paths through a control-flow graph, the data structure representing paths that might be traversed by a program during its execution. When the path exploration notices an anomaly, a warning is generated.

An astronomical number of combinations of circumstances must be modeled and explored, so CodeSonar employs a variety of strategies to ensure scalability. For example, procedure summaries are refined and compacted during the analysis, and paths are explored in an order that minimizes paging.

Customize Your Analysis

New custom checks can be created easily with the included C API. Many built-in checks can be configured according to local requirements. You can also use the API to define custom metrics.

Team Support Built In

CodeSonar is designed to support large teams. Defects are persistent and tracked across builds, even if code changes. They can be annotated, ranked, assigned, searched for and compared. Support for many team-tools is provided out of the box.
