Who is Ethical Hacker?
Hacking is the process of looking for system vulnerabilities to gain unauthorised access to execute malevolent activities such as deleting files or thieving confidential data. "In order to defeat a hacker, you must think like one." - Council for Ethical Hacking. Thus, hacking is considered legal if carried out with permission and without any malicious intent is known as ethical hacking. Ethical hackers, also known as white hat hackers, find network vulnerabilities and protect computers and networks from the attacks of unethical hackers, also known as black hat hackers.

What does Ethical Hacker do?
Ethical hacking is a preventative approach to data security. An ethical hacker utilises the same tactics as a malevolent hacker to get past a system's defences, but instead of exploiting any flaws they uncover, they offer suggestions on how to patch them so a firm may enhance its overall security. An ethical hacker must research, record their results, and share them with management and IT teams.
As a company solves security flaws, ethical hackers will give input and verification. Exploiting system flaws, sending phishing emails to the organisation's employees in the hopes of obtaining their login credentials, or penetrating the physical boundary are all possibilities. As the security landscape has changed, ethical hackers are now occasionally hired to carry out long-term scams. They will observe and analyse a company for trends that may be exploited.

Abilities & aptitude needed
What are the skills, abilities & aptitude needed to become Ethical Hacker?
Along with experience, continued education, and industry certifications, one must need to build knowledge of cybersecurity, risk management, and information technology infrastructure.
Ethical hackers need strong expertise in information security measures, IT security architecture, and network architecture in hard skills. They must also possess knowledge about various operating systems, including Linux and Windows. Additionally, they should have a working knowledge of firewalls, intrusion detection techniques, and intrusion prevention procedures. Finally, they should also be familiar with scripting or coding computer programming languages like HTML, JSP, ASP, C/C++, Java, Python, etc.
Ethical hackers use analytical skills to gain in-depth knowledge of computer networks and digital systems as well as problem-solving to fix any issues. In addition, creativity helps ethical hackers use innovative techniques to security threats or breaches and foresee possible problems.
They need research and auditing skills to investigate which technologies best meet an enterprise's security needs, often piloting an audit of defences, exposures, and vulnerabilities in the process.
They must demonstrate project management skills, time management, organisational and strong written and verbal communication skills to prepare reports for colleagues.
Successful white hackers are proactive, investigative, inquisitive, and detail-oriented individuals who can catch slight changes and correctly diagnose a system's performance that may indicate a security breach, unauthorised software or malware.
