What Is Ethical Hacking? – The Importance Of Digital Security

The ethics of hacking, often referred to as ‘ pen testing ‘ or ‘penetration testing,’ consists of evaluating computer systems and networks to discover possible vulnerabilities and flaws in their security. Unlike malicious hackers who seek to exploit existing vulnerabilities for illicit purposes, ethical hackers do so to strengthen the security of an organization or system.

In this context, ethical hacking has become an essential tool for companies, governments, and organizations that want to protect their digital assets and confidential data.

Phases of ethical hacking

The ethical hacking process is generally divided into several phases:

  • Recognition and information collection
  • Identify the target and collect relevant information, such as IP addresses, domain names, and organization details.
  • Vulnerability scanning and enumeration
  • Scan the network and systems for open ports, services, and known vulnerabilities.
  • Exploitation and obtaining access
  • Exploit identified vulnerabilities to gain access to systems or applications.
  • Access maintenance and post-exploitation
  • Maintain access to investigate further and gather additional information.
  • Fingerprint coverage and trace elimination
  • Delete clues and evidence of the activity carried out to avoid detection.

Ethical principles for ethical hackers

Ethical hackers are guided by ethical principles and standards of conduct that help them carry out their activities responsibly and legally.

Here are some of the fundamental ethical principles for ethical hackers:

Consent and authorization: Ethical hackers must obtain explicit consent and written approval before conducting penetration tests or evaluating the security of any system or network. It means they should not engage in activities without the system owner’s permission.

Confidentiality: Information and data obtained during security testing must be treated with the utmost confidentiality.

Integrity and not harm: Ethical hackers must conduct their tests in a way that does not cause unnecessary or irreversible damage to systems and data. The goal is to identify vulnerabilities, not exploit them to cause harm.

Responsibility and Accountability: Ethical hackers ensure that identified security issues are appropriately reported, and action is taken to correct them. They must also take responsibility for their actions.

Constant Learning: Ethical hackers must commit to learning and staying current on the latest cybersecurity techniques and threats.

Do not profit illegally: Ethical hackers should not use their knowledge and skills to enrich themselves, steal confidential information, or carry out illegal activities. Your focus should be on protecting and improving cybersecurity.

Cooperation with authorities: In cases where criminal activity is discovered during security testing, ethical hackers must fully cooperate with legal authorities and comply with their legal obligations.

These ethical principles are critical to ensuring that ethical hackers act responsibly and benefit society by protecting systems and data rather than putting them at risk. Ethical hackers play an essential role in cybersecurity by helping to strengthen cyber defenses and prevent malicious attacks.

Legal liability and data protection

  • All actions taken by ethical hackers must be within the limits of the law.  It involves compliance with laws and regulations related to cybersecurity and data safeguarding.
  • Ethical hackers must maintain a comprehensive record of all actions taken during security testing. Covering the approaches used, achievements achieved, and sustained communication with the client or entity responsible for the system.

Responsible Vulnerability Disclosure

  • Responsibly inform the organization that owns discovered vulnerabilities and give them time to fix the problem before making it public.
  • Ethical hackers must follow responsible disclosure practices if a critical vulnerability is discovered. It involves notifying the organization that owns the system before publicizing the exposure, allowing them time to remediate it.

Examples of the use of the ethical hacker

Ethical hackers play an essential role in cyber security by helping to identify and fix vulnerabilities before cybercriminals explore them. Here are examples of situations where ethical hackers are very useful:

System Penetration Testing: Ethical hackers perform penetration tests on networks and computer systems to identify weaknesses and vulnerabilities. It may include security testing on web applications, servers, databases, and other digital assets.

Website Security Assessment: Ethical hackers can help businesses assess the security of their websites and online applications.

Mobile App Security Analysis: Ethical hackers can perform security analysis on mobile applications to identify vulnerabilities that attackers could exploit to compromise users’ privacy and security.

Cyberattack Simulation: By simulating cyberattacks, ethical hackers can help organizations assess their preparedness for security incidents and their ability to defend against real threats.

Internal security audits: Ethical hackers can conduct internal security audits to evaluate compliance with security policies, identify risks, and propose corrective measures.

Security Breach Investigation: In a security breach, ethical hackers may be hired to investigate and determine how the breach occurred, what data was compromised, and how similar incidents can be prevented.

Wireless network security testing: Ethical hackers can evaluate the security of wireless networks. Such as corporate Wi-Fi networks, to identify vulnerabilities and ensure they are protected from unauthorized intrusions.

Internet of Things (IoT) Security Assessment: With the growth of IoT devices, ethical hackers can help protect these devices against potential attacks that could compromise users’ privacy and security.
