Core Activities and Techniques

White-hat hackers employ a systematic approach to uncover and resolve security flaws. Authorized penetration testing is their primary method, simulating real-world attacks to breach organizational networks and expose weaknesses White-hat hackers conduct authorized penetration testing to breach organizational networks and identify vulnerabilities.. This controlled “breach” allows security teams to patch vulnerabilities before malicious hackers exploit them.

Social engineering testing is another critical activity. Through anti-phishing campaigns and simulated bait scenarios, white-hat hackers evaluate employee awareness and resistance to manipulation White-hat hackers conduct social engineering testing through anti-phishing campaigns to evaluate employee security awareness.. These tests reveal human-factor vulnerabilities that technical measures alone cannot address.

They also perform controlled denial-of-service (DoS) attacks to determine how systems respond under extreme load, identifying bottlenecks and single points of failure They perform controlled denial-of-service (DoS) attacks to identify system vulnerabilities and protection thresholds.. Additionally, white-hat hackers reverse engineer malware, analyze security incidents, and conduct network scans to pinpoint and remediate risks They reverse engineer malware, analyze security incidents, and conduct network scans to identify and patch vulnerabilities..
