An ethical hacking certification can help validate knowledge of penetration testing, vulnerability assessment, network security, web application security, and responsible security practices. Certifications such as EC-Council’s CEH and GIAC’s offensive-operations credentials take different approaches to validating these skills, so it is worth checking the syllabus, practical requirements, exam format, and recognition of the credential before choosing one. Certification is most useful when combined with hands-on practice in areas such as Linux, networking, scripting, web security, vulnerability scanning, and penetration-testing methodologies.
