Security Testing is a type of software testing that focuses on identifying vulnerabilities, weaknesses, or security flaws in a system, application, or network. The goal is to ensure that the system is protected from potential threats, unauthorized access, data breaches, and attacks. It verifies that sensitive data is safeguarded and that the system adheres to security standards and best practices.

Key Objectives of Security Testing:​

1. Confidentiality: Ensuring that sensitive data is not exposed to unauthorized users or systems.
2. Integrity: Verifying that data is not tampered with during transmission or storage.
3. Authentication: Ensuring that users are who they say they are through mechanisms like passwords, biometrics, or two-factor authentication.
4. Authorization: Ensuring that users can only access resources they are allowed to, based on their role or permissions.
5. Non-repudiation: Making sure that actions performed within the system cannot be denied by the user, ensuring accountability.
6. Availability: Ensuring that the system remains accessible and functional, even during attacks like Distributed Denial of Service (DDoS).

Common Types of Security Testing:​

1. Vulnerability Scanning: Automated scanning to find known vulnerabilities in a system.
2. Penetration Testing: Ethical hacking performed to exploit system vulnerabilities and simulate real-world attacks.
3. Risk Assessment: Identifying and evaluating potential security risks to the system.
4. Security Audits: A comprehensive review of the system's security policies, procedures, and measures.
5. Ethical Hacking: Authorized testing performed by ethical hackers to identify security gaps.
6. Fuzz Testing: Feeding random or unexpected input into the system to identify vulnerabilities.

Types of Security Threats Addressed:​

• SQL Injection
• Cross-Site Scripting (XSS)
• Cross-Site Request Forgery (CSRF)
• Buffer Overflow
• Denial of Service (DoS) and Distributed Denial of Service (DDoS)
• Malware and Ransomware

Security testing is a critical part of the software development lifecycle (SDLC), helping developers build more secure applications and systems while minimizing risks and vulnerabilities.
