One common mistake that beginner ethical hackers make is not thoroughly understanding the legal and ethical boundaries of hacking. It’s important to always obtain proper authorization before attempting to test the security of a system or network. Additionally, some beginners may overlook the importance of properly documenting and reporting any vulnerabilities they discover, which can lead to misunderstandings and potential legal issues. Lastly, relying solely on automated tools and not conducting proper manual testing can result in overlooking.

There are so many beginners out there who over look the importance of learning  linux and networking and start getting into the hacking tools .Establishing a solid base is the necessary and crucial step .

Also, don’t forget to jot down and report any security loopholes you find; skipping this step could land you in some hot water. And here’s another tip: don’t rely only on those fancy automated tools. Getting your hands dirty with some manual testing is key because it helps catch the sneaky bugs that machines might miss. Keep learning and practicing—nobody becomes a pro overnight!

 Important : Things to follow for a strong foundation in basics for Ethical hacking 

• Gain a solid understanding of fundamental networking concepts, including IP addresses, TCP/IP protocols, and data transmission method.
• Best thing to start with is Linux Administration ,one can start with red hat linux ,ubuntu or kali linux as operating system is essiential concept in ethical hacking
•  Learn to operate key hacking tools like Nmap, Wireshark, and Metasploit which are essential for identifying vulnerabilities through scanning and exploitation  techniques.
• Familiarize yourself with prevalent security risks such as SQL injection, cross-site scripting (XSS), and buffer overflows to better protect against them.
• Deepen your knowledge on various forms of malware—like viruses, worms, and ransomware—and understand their mechanisms to compromise system securities. 
• Set up a secure laboratory setting where you can hone your hacking skills responsibly in an environment that mimics real-world systems but keeps safety at the forefront. 
• Embrace ethical hacking methodologies encompassing reconnaissance, scanning phases through exploitation and post-exploitation stages to conduct thorough security assessments.
• Stay current with new developments in the cybersecurity field by continuously updating yourself through relevant news sources and advanced technologies that help predict upcoming threats effectively.
• Cultivate robust problem-solving abilities along with critical thinking skills required for pinpointing security anomalies efficiently so you can address them accurately
