Best Operating System (OS) for Ethical Hacking

To exploit the vulnerabilities so they can then be repaired, ethical hacking identifies weaknesses in computer systems or networks. Hackers exploit a range of methodologies to identify dangers and eventually enhance safety. They can break into networks or computers using Linux-based operating systems. To stop cybersecurity threats, there are various applications. The field of hacking, which was present in computing for more than 50 years, is highly broad and includes a wide range of activities. 

In the modern cyber world, several diverse attacks take place per hour and therefore are carried out by expert hackers, and attackers. A hacking operating system is the most fundamental tool needed by any hacker. The Linux kernel typically serves as the foundation for operating systems that specialize in hacking. These operating systems are cutting-edge functioning systems because they come with several ethical hacking and penetration testing capabilities. 

What is Ethical Hacking? 

In revealing potential data breaches and network risks, ethical hacking is a legitimate method that involves finding flaws in an application, system, or organization's infrastructure and getting beyond system security. In order to find vulnerabilities that harmful hackers can exploit or eliminate, ethical hackers search the system or network. It may secure the data to wedge attacks or neutralize them. 

In addition to assessing the system's defences, the enterprise that controls the system or network permits Cyber Security professionals to carry out such actions. Therefore, this process is planned, approved, and—more importantly—legal, in contrast to malicious hacking. 

Of course, there are many different factors to consider in this precise and frequently lengthy system. An ethical hacker also referred to as a white-hat hacker will search for vulnerabilities using a variety of techniques. Additionally, they will carry out several other activities related to general cyber security. This may consist of: 

  • identifying weaknesses 
  • Testing for penetration 
  • collecting information regarding entry points 
  • infrastructures being scanned for weaknesses 
  • exploiting flaws to gain access to systems and networks 
  • concealing their presence and avoiding detection 
  • putting together analyses and reports for the attempts

What are the Key Concepts of Ethical Hacking?

Four fundamental protocol principles followed by hackers are: 

Be lawful:  Before entering and conducting a security evaluation, get the necessary approval. 

Establish the scope:  Establish the assessment's parameters to ensure that the ethical hacker's work is legal and within the organization's permitted restrictions. 

Inform about vulnerabilities:  All vulnerabilities found even during evaluation should be reported to the organization. Give suggestions for repairing these vulnerabilities. 

Be sensitive to data:  Cybersecurity professionals may need to accept a non-disclosure agreement in addition to other terms and conditions requested by the evaluated firm, depending on how sensitive the data is.

The Preferred Operating Systems of Professional Hackers?

According to claims of high-risk hacking, some hackers use Microsoft Windows to remain undetected. Since Windows is a popular target for hackers, they must employ Windows-only environments in order to use Windows-based malware, the.NET framework, Trojans, or viruses. Hackers create a lightweight bootable ghost image that cannot be traced back to them using inexpensive disposable laptops that buy off Craigslist. These computers include unique SD card and USB ports that, if necessary, are simple to trash, bury, or even ingest. 

Several attackers go above and above by adding additional readable storage for operating system read-only divisions and restricted persistent local storage. Some, the worried kind, go even further and include a hotkey panic button for instant RAM cleaning. 

A compact, encoded SD card is produced with the bootable OS ghost image. The laptop burner is then methodically separated and discarded. The physical destruction of the RAM, hard drive, and network card is given particular care by the hackers. Such computers are occasionally destroyed with a blowtorch or a sledgehammer.
