🛡️ What is Code Security Scanning?
Code security scanning is an automated process that analyzes source code, compiled applications, or running systems to identify security vulnerabilities, coding errors, and potential attack vectors. This critical security practice helps developers catch security issues early in the development lifecycle, significantly reducing the cost and risk of vulnerabilities reaching production environments.
Modern security scanners use pattern matching, data flow analysis, and machine learning to detect a wide range of security issues including injection attacks, cross-site scripting (XSS), authentication flaws, and hardcoded credentials. The goal is to shift security left in the development process, making security an integral part of coding rather than an afterthought.
💡 Pro Tip: Implementing automated security scanning early in development can reduce security fix costs by up to 100x compared to fixing issues in production.

🏆 OWASP Top 10 Security Risks (2021)
The Open Web Application Security Project (OWASP) Top 10 represents the most critical security risks to web applications. Our security scanner specifically targets these vulnerabilities to ensure comprehensive coverage of the most common attack vectors.
A01:2021 - Broken Access Control
Restrictions on authenticated users are not properly enforced
A02:2021 - Cryptographic Failures
Failures related to cryptography that lead to sensitive data exposure
A03:2021 - Injection
User-supplied data is not validated, filtered, or sanitized by the application
A04:2021 - Insecure Design
Risks related to design flaws and missing security controls
A05:2021 - Security Misconfiguration
Missing appropriate security hardening or improperly configured permissions
A06:2021 - Vulnerable Components
Using components with known vulnerabilities or outdated versions
A07:2021 - Authentication Failures
Broken implementation of authentication and session management
A08:2021 - Data Integrity Failures
Code and infrastructure that do not protect against integrity violations
A09:2021 - Logging & Monitoring
Insufficient logging, detection, monitoring, and active response
A10:2021 - Server-Side Request Forgery
SSRF flaws when web applications fetch remote resources
🔐 Secrets Detection & API Key Security
One of the most critical security issues in modern applications is the exposure of secrets like API keys, passwords, and tokens in source code. Our scanner detects over 15 types of common secrets and provides specific remediation guidance for each.
Common Secrets We Detect:
- • AWS Access Keys
- • GitHub Tokens
- • Google API Keys
- • Firebase Keys
- • JWT Tokens
- • Stripe API Keys
- • PayPal Tokens
- • Slack Tokens
- • Discord Bot Tokens
- • Twilio Credentials
- • Database URLs
- • Private Keys
- • WordPress Config
- • Mailgun Keys
- • Custom API Keys
🛡️ Best Practices for Secret Management:
- • Use environment variables for all secrets
- • Implement proper .gitignore rules
- • Use secret management tools like HashiCorp Vault
- • Rotate credentials regularly
- • Never commit configuration files with secrets
- • Use encrypted configuration in production
⚖️ Static vs Dynamic Security Analysis
Understanding the difference between static and dynamic analysis helps you choose the right security testing approach for your applications. Our tool focuses on static analysis, which examines code without executing it.
📄 Static Analysis (SAST)
- ✅ Analyzes source code without execution
- ✅ Fast and scalable
- ✅ Integrates easily into CI/CD
- ✅ Finds coding errors early
- ✅ No runtime environment needed
- ❌ May produce false positives
- ❌ Cannot detect runtime vulnerabilities
🏃♂️ Dynamic Analysis (DAST)
- ✅ Tests running applications
- ✅ Finds runtime vulnerabilities
- ✅ Lower false positive rate
- ✅ Tests real-world scenarios
- ✅ Language agnostic
- ❌ Requires running application
- ❌ Slower and more resource intensive
