How to Become Ethical Hacker After 12th Commerce


In today’s digital age, the demand for skilled cybersecurity professionals, particularly ethical hackers, is on the rise. Ethical hackers play a crucial role in identifying vulnerabilities and securing computer systems and networks. If you have completed your 12th grade in either science or commerce or arts and have an interest in technology and cybersecurity, this blog post will guide you on the path to becoming an ethical hacker.

Understand Ethical Hacking

A. Define ethical hacking and its importance in cybersecurity:

Ethical hacking, also known as white-hat hacking or penetration testing, refers to the practice of intentionally attempting to identify vulnerabilities and weaknesses in computer systems, networks, and applications. Ethical hackers are authorized professionals who use their skills and knowledge to assess the security of systems, helping organizations identify and address potential threats before they can be exploited by malicious actors. 

Ethical hacking plays a crucial role in cybersecurity as it helps strengthen the overall security posture of an organization by proactively identifying and mitigating vulnerabilities.

B. Differentiate ethical hacking from malicious hacking:

Ethical hacking is often misunderstood as being synonymous with malicious hacking or “black-hat hacking.” However, there are significant differences between the two:

  • Authorization: Ethical hacking is performed with proper authorization from the system or network owner. The ethical hacker works under legal and ethical boundaries and follows a predefined scope of work. In contrast, malicious hacking involves unauthorized access and malicious intent.
  • Intent: Ethical hackers have a legitimate and lawful purpose behind their actions. They aim to identify vulnerabilities and help organizations improve their security. Malicious hackers, on the other hand, have malicious intent and exploit vulnerabilities for personal gain, damage, or disruption.
  • Legal Compliance: Ethical hackers adhere to legal frameworks, regulations, and ethical guidelines. They work within the boundaries of the law and obtain necessary permissions before conducting security testing. Malicious hackers, by contrast, violate laws and engage in illegal activities.

C. Explore the various domains and roles within ethical hacking:

Ethical hacking encompasses various domains and roles that contribute to the overall cybersecurity landscape. Some of the key domains and roles within ethical hacking include:

  • Penetration Testing: Penetration testers, also known as ethical hackers, simulate real-world cyber attacks to identify vulnerabilities in systems, networks, or applications. They perform comprehensive assessments, analyze the security posture, and provide detailed reports with recommendations for improvements.
  • Vulnerability Assessment: Vulnerability assessors focus on identifying and assessing vulnerabilities within computer systems, networks, or applications. They use specialized tools and techniques to scan for weaknesses and provide risk assessments to organizations.
  • Web Application Security: Web application security specialists focus on identifying and addressing vulnerabilities specific to web applications. They assess web applications for common security flaws, such as cross-site scripting (XSS) or SQL injection, and recommend appropriate security measures.
  • Network Security: Network security professionals specialize in assessing and securing computer networks. They identify weaknesses in network infrastructure, routers, firewalls, and other network components, and propose measures to enhance network security.
  • Incident Response and Forensics: Incident response teams investigate and respond to cybersecurity incidents. They analyze the scope and impact of a breach, gather evidence, and implement measures to prevent future incidents. Digital forensics experts play a vital role in collecting and analyzing evidence related to cybercrimes.
  • Secure Code Analysis: Secure code analysts review application source code to identify security vulnerabilities. They assess coding practices, analyze potential weaknesses, and suggest improvements to enhance the security of software applications.

Develop a Strong Foundation

A. Strengthen your understanding of computer networks and operating systems:

To become an ethical hacker, it’s crucial to have a strong foundation in computer networks and operating systems. This includes understanding the fundamentals of network architecture, protocols, and how data is transmitted over networks. Familiarize yourself with concepts such as IP addressing, subnetting, routing, and TCP/IP. Learn about different operating systems like Windows, Linux, and macOS, including their file systems, user management, and security features.

B. Gain knowledge of programming languages such as Python, C++, or Java:

Programming languages are essential for ethical hackers as they allow for the development of tools, scripts, and exploits. Python is particularly popular due to its simplicity and versatility in cybersecurity tasks. Learn the basics of programming, such as variables, control structures, loops, functions, and object-oriented programming concepts. 

Additionally, gaining proficiency in languages like C++, Java, or scripting languages like PowerShell can expand your capabilities in specific areas.

C. Learn about databases and SQL (Structured Query Language):

Databases are prevalent in many applications and understanding them is crucial for ethical hackers. Learn about database management systems (DBMS) such as MySQL, Oracle, or Microsoft SQL Server. 

Familiarize yourself with Structured Query Language (SQL), as it is used to communicate with and manipulate databases. Understand concepts such as data modeling, table relationships, and SQL statements for querying and modifying data.

D. Familiarize yourself with web technologies and protocols:

Web technologies play a significant role in modern-day applications and their security. Learn about web development concepts such as HTML, CSS, and JavaScript. Gain knowledge of web frameworks like Django or Ruby on Rails. 

Understand how web servers work, including the HTTP/HTTPS protocols and their request-response mechanisms. Explore common web vulnerabilities like cross-site scripting (XSS), SQL injection, and cross-site request forgery (CSRF), and study techniques to mitigate these risks.

Pursue Relevant Education and Certifications

Consider a bachelor’s degree in computer science or cybersecurity:

Obtaining a bachelor’s degree in computer science or cybersecurity can provide you with a solid educational foundation for a career in ethical hacking. These programs cover essential topics such as programming, computer networks, information security, cryptography, and ethical hacking methodologies. A degree can enhance your understanding of core concepts and provide a broader knowledge base that complements your practical skills.

B. Explore certifications like Certified Ethical Hacker (CEH), CompTIA Security+, or Offensive Security Certified Professional (OSCP):

Certifications in ethical hacking and cybersecurity validate your skills and knowledge, making you more marketable in the industry. Consider certifications such as:

Certified Ethical Hacker (CEH): Offered by EC-Council, CEH is a popular certification that covers a wide range of ethical hacking techniques and methodologies.

CompTIA Security+: This entry-level certification from CompTIA covers foundational cybersecurity concepts, including ethical hacking, network security, and risk management.

Offensive Security Certified Professional (OSCP): Offered by Offensive Security, OSCP is a highly regarded certification that focuses on practical hands-on skills in penetration testing and vulnerability assessment.

Research and choose certifications that align with your career goals and interests. These certifications demonstrate your expertise and dedication to potential employers and clients.

C. Participate in online courses or boot camps focused on ethical hacking:

Online courses and boot camps provide focused and practical training in ethical hacking. They offer flexibility, allowing you to learn at your own pace and from anywhere. Look for reputable platforms or organizations that provide courses specifically tailored to ethical hacking. 

Some popular platforms include Udemy, Coursera, and Offensive Security’s online training programs. These courses often provide hands-on exercises, real-world scenarios, and practical guidance from industry professionals, enabling you to develop the necessary skills and techniques.
