Static Code Analysis
Static Code Analysis is a technique used to identify potential vulnerabilities in software code before it is executed. It is an automated method that analyzes the source code of an application to identify potential security flaws and other issues that could lead to software bugs and system failures.
Static code analysis is an essential part of any software development process, as it helps identify potential vulnerabilities early in the development cycle when they are easier and less expensive to fix. This technique can be used for different programming languages such as C, C++, Java, Python, etc.
How Static Code Analysis Works:
Static code analysis tools analyze the source code of an application without executing it. The tools analyze the code line by line, looking for potential vulnerabilities and errors. The analysis can be performed in different ways, depending on the tool used and the programming language of the application.
Static code analysis tools use different algorithms to identify potential vulnerabilities. Some tools use a rule-based approach, where they look for specific patterns of code that are known to be vulnerable. Other tools use a more advanced approach that involves data flow analysis, which examines how data is processed throughout the application to identify potential vulnerabilities.
