1. What Do Ethical Hackers Do?
Ethical hackers, also known as white hat hackers or penetration testers, engage in a variety
of activities with the primary goal of identifying and improving security vulnerabilities
within computer systems, networks, and applications. Their actions are legal, authorized,
and conducted with the intent of enhancing cybersecurity. Here's what ethical hackers do:
• Vulnerability Assessment: Ethical hackers assess the security posture of systems
and networks to identify potential weaknesses and vulnerabilities that could be
exploited by malicious hackers.
• Penetration Testing: They conduct controlled and simulated attacks on systems
and networks to test their defenses. This includes trying to exploit vulnerabilities to
determine the extent of potential damage.
• Network Security Testing: Ethical hackers evaluate the security of network
configurations, routers, switches, firewalls, and intrusion detection systems to
ensure they are properly configured and protect against unauthorized access.
• Web Application Testing: They assess web applications for security flaws, such as
SQL injection, Cross-Site Scripting (XSS), and Cross-Site Request Forgery (CSRF), to
prevent potential exploitation.
• Wireless Network Testing: Ethical hackers assess the security of wireless
networks to identify weak encryption, unauthorized access points, and other
vulnerabilities.
• Social Engineering Testing: They test an organization's susceptibility to social
engineering attacks, such as phishing, pretexting, or tailgating, and provide training
to employees to improve security awareness.
• Incident Response: Ethical hackers assist organizations in responding to security
incidents by analyzing the breach, identifying the root cause, and helping implement
measures to prevent future incidents.
• Security Audits: They conduct security audits of an organization's policies,
procedures, and configurations to ensure compliance with security best practices
and industry standards.
• Security Awareness Training: Ethical hackers educate employees and
stakeholders about cybersecurity best practices, helping them recognize and
respond to security threats effectively.
• Risk Assessment: They assess the overall cybersecurity risk of an organization,
prioritize vulnerabilities, and recommend mitigation strategies to reduce risk.
• Security Tool Development: Some ethical hackers develop custom security tools
and scripts to automate tasks or assist in the identification of vulnerabilities.
• Compliance Testing: Ethical hackers assess an organization's compliance with
regulatory requirements related to cybersecurity, such as GDPR, HIPAA, or PCI DSS.

2. • Advisory Services: They provide recommendations and guidance on how to
improve an organization's security posture, including the implementation of
security controls and best practices.
• Continuous Learning: Ethical hackers stay updated on the latest cybersecurity
threats, tools, and techniques to adapt and respond effectively to evolving security
challenges.
• Code Review: They review the source code of applications to identify security flaws
and suggest improvements to make them more secure.
Ethical hackers play a crucial role in helping organizations proactively identify and mitigate
security risks, safeguard sensitive data, and maintain the confidentiality, integrity, and
availability of digital assets. Their efforts contribute to overall cybersecurity resilience and
the protection of systems and information from cyber threats.
