Tools for Static Code Analysis

Semgrep

• A tool for finding bugs and enforcing code standards.

SonarQube

• A platform to perform automatic reviews with static analysis to detect bugs, vulnerabilities, and code smells.

Fortify

• A static code analysis tool that identifies security vulnerabilities in your code.

Methodologies

• Regular Code Reviews: Manually reviewing code for potential security issues.
• CI/CD Integration: Automating code analysis within Continuous Integration/Continuous Deployment pipelines.

Command Examples and Demonstrations

Analyzing a Downloaded Source Code

• Scenario: Suppose you've found a backup file of source code from example.com, say source-backup.zip.
• Unzip the File: unzip source-backup.zip -d source_code
• Example with Semgrep:

  semgrep --config=p/ci source_code
  

  This command runs Semgrep on the unzipped source code to identify common security issues.

SonarQube Analysis

• Setting up a SonarQube server: First, set up a local SonarQube server for analysis.
• Analyzing with SonarQube:

  sonar-scanner     -Dsonar.projectKey=example_project     -Dsonar.sources=./source_code     -Dsonar.host.url=http://localhost:9000     -Dsonar.login=your_sonarqube_token
  

  This command sends the source code to SonarQube for analysis.

Fortify Scan

• Scanning with Fortify:

  sourceanalyzer -b example_project source_code
  fortifysoftware -b example_project -scan -f example_project.fpr
  

  This sequence of commands compiles the code for analysis and then runs a Fortify scan.

Note: Always ensure you have the legal right to analyze and scan the code. Unauthorized analysis may lead to legal repercussions.
