The rise of cybercrime has led to a shift in the security landscape, resulting in an increased demand for white hat hackers. A white hat hacker is an ethical computer security expert who works to identify security vulnerabilities and develop solutions to protect networks and systems from malicious attacks. They use their knowledge and skills to help organizations prevent and respond to cyber threats, often by finding weaknesses in their security systems.

As organizations become increasingly reliant on digital infrastructure, the need for white hat hackers has grown to ensure that the data and systems are secure from outside threats. Their expertise is invaluable to organizations, as it can help them protect their data and systems from malicious actors.

Steps How to Become

Develop a Strong Understanding of Computer Systems. Start by gaining a strong understanding of computer systems and networking concepts. You need to understand how computer systems work, from the basic hardware components up to the software programs that run on them. You should also understand network concepts such as different types of networks, the OSI model, and basic network protocols such as TCP/IP.
Get Familiar with Different Operating Systems. As a white hat hacker, you should be familiar with different operating systems such as Windows, Linux, Mac OS, and others. Knowing how to work with these different systems is essential for being able to identify and exploit vulnerabilities in them.
Learn Programming and Scripting Languages. Knowing how to write code is an essential skill for any ethical hacker. You should learn at least one programming language such as C++ or Python, as well as scripting languages such as Bash and PowerShell.
Learn About Cybersecurity Principles. You should also learn about different cybersecurity principles and best practices. This includes learning about authentication protocols, encryption algorithms, firewalls, intrusion detection systems, and more.
Get Certified in Ethical Hacking. To demonstrate your knowledge and experience in ethical hacking, you should consider getting certified. There are many different certifications available, such as the Certified Ethical Hacker (CEH) certification and the Offensive Security Certified Professional (OSCP) certification.
Practice Your Skills. The best way to hone your skills as an ethical hacker is to practice them. You can do this by setting up your own lab environment, where you can practice hacking techniques. You can also take part in Capture the Flag (CTF) competitions, which are online challenges where you have to solve a series of security-related tasks.

Staying up to date and efficient as a white hat hacker requires dedication and hard work. Keeping track of new security threats, technologies, and vulnerabilities is essential to ensure that the systems being protected are secure. Staying up to date requires staying informed of the latest news and developments in the security industry.

This can be done through reading blogs and journals, attending conferences and seminars, and following security experts on social media. staying efficient requires staying organized and having a well-structured workflow. Keeping track of tasks and projects, automating as many processes as possible, and making use of the latest tools and technologies can help streamline the work process and increase efficiency.

Finally, it is important to build relationships with other security professionals in order to stay informed, collaborate on projects, and help each other stay up to date and efficient.
