  • Tests apps for insecure storage, improper encryption, and weak authentication.
  • Protects sensitive data stored on mobile devices.
• Common Tools Used:
  • MobSF (Mobile Security Framework)
  • Drozer
  • OWASP Mobile Testing Guide

7. Social Engineering Testing

Social engineering testing is designed to evaluate an organization’s susceptibility to human-based attacks such as phishing, baiting, and pretexting. The goal is to test whether employees are following security protocols and to identify weaknesses in training and awareness programs.

• Key Benefits:
  • Tests the effectiveness of employee security awareness programs.
  • Helps identify weaknesses in human factors that could lead to security breaches.
  • Simulates real-world attacks to assess response and readiness.
• Common Methods Used:
  • Phishing campaigns
  • Spear-phishing attempts
  • Vishing (voice phishing)
  • Physical social engineering attacks

The Security Testing Process

A typical security testing service follows a well-defined process to ensure that all vulnerabilities are thoroughly identified and addressed. Here’s a high-level overview of the security testing process:

1. Planning and Scoping
   • Understand the organization’s security goals and define the scope of testing.
   • Identify critical systems, applications, and network components to be tested.
2. Vulnerability Assessment and Discovery
   • Conduct a comprehensive scan for known vulnerabilities using automated tools.
   • Analyze system configurations, code, and infrastructure.
3. Exploit Testing (Penetration Testing)
