What is Ethical Hacking?
Ethical hacking is popular for white-hat hacking and is also the best way of using hacking techniques to check vulnerabilities in computer systems or networks with admin permission. Ethical hacking aims to monitor security by searching for and fixing flaws before malicious actors can exploit them.
Common techniques used in ethical hacking:
Vulnerability scanning: It helps to check weaknesses in systems and networks.
Penetration testing: Simulating attacks to assess a system’s resilience.
Social engineering: It helps to operate to gain unauthorized access.
Reverse engineering: Analyzing software or hardware to understand its components.
It is a useful and important factor of cybersecurity and allows firms to protect their secret works from cyber threats.
What are the key principles of ethical hacking?
Ethical hacking, also known as white-hat hacking, is governed by a set of principles that ensure its legality, ethicality, and effectiveness. Here are some of the key principles:
- Permission: Ethical hackers always obtain explicit permission from the system or network owner before conducting any tests or assessments. This ensures that their actions are legal and authorized.
- Non-Malice: Ethical hackers do not intend to cause harm or damage to the system or network. Their goal is to identify vulnerabilities and help improve security.
- Confidentiality: Ethical hackers must maintain the confidentiality of any information they discover during their assessments. This includes protecting sensitive data and avoiding unauthorized disclosure.
- Integrity: Ethical hackers should not alter or modify any system or network components without the owner’s consent. Care should be taken to protect the integrity of the systems.
- Availability: While ethical hackers may temporarily disrupt system or network availability during their tests, they should strive to minimize any downtime and restore systems to their original state as soon as possible.
- Legal Compliance: Ethical hackers must adhere to all applicable laws and regulations, including data privacy laws and cybersecurity regulations.
- Professionalism: Ethical hackers should professionally conduct their activities, following industry best practices and standards.
- Transparency: Ethical hackers should maintain open communication with the system or network owner, providing regular updates on their findings and recommendations.
- Non-Disclosure Agreements (NDAs): In many cases, ethical hackers will sign NDAs with the system or network owner to protect sensitive information.
These ethical hackers can help organizations enhance their security posture while ensuring that their actions are legal, ethical, and beneficial.

What are the 5 steps of ethical hacking?
Ethical hacking, also known as white-hat hacking, is a systematic process involving several key steps. Here are the five main steps:
- Reconnaissance: This function includes collecting information about the target system or network. You can do this with the help of various techniques like:
- Passive reconnaissance: Gathering information publicly available online, such as social media profiles, company websites, and public records.
- Active reconnaissance: Communication with the target system or network to collect the information like scanning ports or sending probes.
- Scanning: You can use this automated tool to monitor the open ports, services, and vulnerabilities in the target network or system. This data is useful for segregating attack vectors.
- Enumeration: Once vulnerabilities have been identified, ethical hackers can enumerate the system or network to gather more detailed information about its configuration and resources. This informs about how one can exploit vulnerabilities and acquire unauthorized access.
- Gaining Access:
- Exploiting software vulnerabilities: It is used to understand vulnerabilities in software applications to gain access.
- Social engineering: Manipulating people to gain unauthorized access.
- Phishing: Sending deceptive emails or messages to trick people into revealing sensitive information.
- Maintaining Access: Once access has been gained, ethical hackers may attempt to maintain access and escalate their privileges. This can involve installing backdoors or compromising additional systems.
It’s important to note that ethical hacking is a complex process that requires specialized knowledge and skills. It’s crucial to obtain explicit permission from the system or network owner before conducting any hacking activities.
