- Strong understanding of common application security vulnerabilities (such as SQL injection, XSS, CSRF, insecure deserialization, etc.) and OWASP Top 10.
- Proficiency in using and configuring vulnerability scanners (Nessus, Qualys, or similar) and interpreting their results.
- Familiarity with cloud security testing and testing applications hosted on platforms like AWS, Azure, or Google Cloud.
- Understanding of DevSecOps practices and experience integrating security testing into CI/CD pipelines.
Experience:
- Minimum of 5-7 years of experience in information security, with at least 3 years focusing on penetration testing, vulnerability assessment, and application security.
- Proven track record of executing penetration tests and exploiting vulnerabilities in complex systems and applications.
-
- Experience with vulnerability scanning tools (e.g., Nessus, Qualys, OpenVAS) and penetration testing tools (e.g., Metasploit, Burp Suite, Kali Linux).
- Familiarity with common security frameworks and compliance requirements (e.g., NIST, ISO 27001, GDPR, PCI-DSS)
- Relevant certifications (e.g., CEH, OSCP, CISSP, CISM, GIAC) are strongly preferred.
