What is security Testing?
security testing is a type of software testing that identifies vulnerabilities, threats, and risks in a software application and measures its potential vulnerabilities. It ensures that the application is secure from external or internal threats.
security Testing Objectives
- Identify Vulnerabilities: Find security weaknesses in the application
- Assess Risk Levels: Determine the severity of security issues
- Validate security Controls: Ensure security measures work properly
- Compliance Verification: Meet regulatory and industry standards
- Threat Modeling: Understand potential attack vectors
- security Awareness: Educate development teams

Example
// security Testing Categories
const securityTestingTypes = {
"Vulnerability Assessment": {
"Purpose": "Identify known security vulnerabilities",
"Scope": "Automated scanning of common issues",
"Tools": "Nessus, OpenVAS, Qualys",
"Frequency": "Regular scans (weekly/monthly)"
},
"Penetration Testing": {
"Purpose": "Simulate real-world attacks",
"Scope": "Manual testing by security experts",
"Tools": "Burp Suite, OWASP ZAP, Metasploit",
"Frequency": "Annual or major releases"
},
"Code Review": {
"Purpose": "Analyze source code for security issues",
"Scope": "Static analysis of application code",
"Tools": "SonarQube, Checkmarx, Veracode",
"Frequency": "Continuous during development"
},
"Compliance Testing": {
"Purpose": "Ensure regulatory compliance",
"Scope": "Specific compliance requirements",
"Standards": "GDPR, HIPAA, PCI DSS, SOX",
"Frequency": "Annual or as required"
}
};
