🔍Static Analysis

NEW

Also known as: Code Analysis, Compile-Time Analysis

Analyzing source code or binaries without executing them to detect defects, vulnerabilities, or policy violations.

DESCRIPTION

Static analysis inspects code structure, types, and patterns to find bugs and security issues early. Tools range from linters to formal verifiers and SAST platforms. It integrates into IDEs and CI pipelines, improving developer feedback. False positives require tuning rules and baselines. Combined with dynamic tests, static analysis hardens software quality and compliance.

ALTERNATIVE DEFINITIONS

Wikipedia

Static program analysis is the analysis of computer software that is performed without actually executing programs.

Stresses non-execution nature across analysis techniques.

Source

OWASP

Static code analysis is a method of debugging by examining source code without executing the program.

Frames static analysis as a debugging and security practice.

TOP QUESTIONS

Why use Static Analysis in CI/CD?

It catches defects and vulnerabilities early. Automated checks prevent regressions and enforce standards.

Category: Relevancy

What types of issues does Static Analysis find?

Security flaws, null dereferences, unused code, complexity hotspots, and style violations.

Category: Overview

How do you reduce false positives in Static Analysis?

Tune rules, baseline existing issues, and prioritize critical findings. Review exceptions regularly.

Category: Best-Practices

What’s the difference between Static and Dynamic Analysis?

Static examines code without running; dynamic tests runtime behavior. Both are complementary for coverage.

Category: Misunderstanding

What are common mistakes with Static Analysis?

Treating all issues equally and ignoring context. Overly strict rules can cause alert fatigue.

Category: Mistakes

How does Static Analysis impact security?

It identifies injection risks, insecure patterns, and misconfigurations. Regular scans strengthen secure coding practices.

Category: Security

Can Static Analysis prove correctness?

Formal methods can provide proofs for certain properties. Practical tools focus on heuristic detection.

Category: Opinion

Which tools support Static Analysis?

SonarQube, ESLint, Pylint, Bandit, Semgrep, and language analyzers. IDEs integrate built-in linters.

Category: Overview

Where to start with Static Analysis?

Enable linters, adopt SAST in CI, and set quality gates. Iterate on rule configurations.
