What is Ethical Hacking


Ethical Hacking is identifying weakness in computer systems or networks to find out threats, vulnerabilities and exploit its weaknesses to gain access using the same knowledge and tools as a malicious hacker, but in a lawful and legitimate manner (written permission)  to assess the security posture of a target system. 

An Ethical Hacker, also known as a whitehat hacker. An ethical hacker’s role is similar to that of a penetration tester, but it involves broader duties. Hacking has been a part of computing for almost five decades and it is a very broad discipline, which covers a wide range of topics. Computers have become mandatory to run a successful business. It is not enough to have isolated computers systems; they need to be networked to facilitate communication with external businesses.  

Who is an Ethical Hacker?

An Ethical Hacker is a skilled professional who has excellent technical knowledge and skills and knows how to identify and exploit vulnerabilities in target systems. He works with the permission of the owners of systems. An ethical Hacker must comply with the rules of the target organization or owner and the law of the land and their aim is to assess the security posture of a target organization/system.

Purpose of Ethical Hacking

The purpose of ethical hacking is to improve the security of the network or systems by fixing the vulnerabilities found during testing.  It includes finding and attempting to exploit any vulnerabilities to determine whether unauthorized access or other malicious activities are possible.They generally find security exposures in insecure system configurations, known and unknown hardware or software vulnerabilities as well as operational weaknesses in process or technical countermeasures.  

An Ethical hacker purpose to protect the privacy of the organization been hacked, Transparently report all the identified weaknesses in the computer system to the organization, Inform hardware and software vendors of the identified weaknesses. Any organization that has a network connection to the Internet or provides an online service should consider subjecting it to penetration testing conducted by ethical hackers.

How to Obtain An Ethical Hacking Certification?

Once you complete the Penetration Testing and Ethical Hacking training (and any other applicable courses), you may consider moving ahead and obtaining a certification. The first step toward certification may be some advanced study on penetration testing and ethical hacking strategies, depending on your experience, skills level, and overall knowledge. You can obtain resources to help you prepare for certification. 

Due to the controversy surrounding the profession of ethical hacking, there are a number of ethical hacking certifications as well as IT certifications related to security that can help individuals become ethical hackers are 

  • Certified Ethical Hacker (CEH) - certificate by the EC-Council, which is the most sought-after and recognizable certification available in this field.
  • Certified Information Systems Auditor (CISA) - This certification is offered by ISACA, a nonprofit, independent association that advocates for professionals involved in information security, assurance, risk management, and governance.
  • Certified information security manager (CISM)CISM is an advanced certification offered by ISACA that provides validation for individuals who have demonstrated the in-depth knowledge and experience required to develop and manage an enterprise information security program.
  • GIAC Security Essentials (GSEC) - This certification created and administered by the Global Information Assurance Certification organization is geared toward security professionals who want to demonstrate they are qualified for IT systems hands-on roles with respect to security tasks.
While not all ethical hacking positions require that you have certifications, it is a valuable credential to present to new or potential employers, as it shows that you have a fundamental knowledge of how to protect their systems using ethical hacking and penetration testing as the cornerstone of your methodology.  Penetration testing and ethical hacking are skill sets as in-demand as anything else in the Cyber Security industry.
