Static Code Analysis

Static code analysis, also known as static analysis or Static Application Security Testing (SAST), is a method of debugging and code review performed without executing the program. By using automated tools to examine an application's source code, bytecode, or binary against a predefined set of rules, this technique identifies potential programming errors, violations of coding standards, and, critically for cybersecurity, security vulnerabilities. This proactive approach allows developers to discover and fix issues like buffer overflows, SQL injection flaws, and improper error handling early in the software development lifecycle, thereby improving the overall quality, maintainability, and security of the software before it is deployed.
