What exactly is ethical hacking?
Ethical hacking is the legal practice of finding weaknesses in an application, system, or organization's infrastructure and circumventing system security to uncover potential data breaches and network threats. Ethical hackers search for faults in a system or network that malicious hackers can exploit or damage. They can increase the security footprint to withstand better or divert attacks.
The organization that controls the system or network allows Cyber Security engineers to undertake such activities to test the system's defenses. In contrast to malicious hacking, this procedure is planned, approved, and, most importantly, legal.
Ethical hackers search for faults in a system or network that malicious hackers can exploit or damage. They collect and analyze data to discover ways to improve the system/network/application security.
They can increase the security footprint, allowing it to withstand or redirect attacks better.
Organizations hire ethical hackers to investigate the vulnerabilities of their systems and networks and design solutions to prevent data breaches. Consider it a technological twist on the old saying, "It takes a thief to catch a thief."
They look for essential weaknesses such as, but not limited to:
Injection attacks
Security settings modifications
Sensitive data exposure
Authentication protocol flaw
Components of a system or network that can serve as access points
What Exactly Are Programming Languages?
People can communicate with computers using programming languages. They are sets of instructions that teach a computer to perform specific tasks. These languages run everything from software and mobile applications to complicated systems in autos and spacecraft. The five basic programming language categories are functional, logic, object-oriented, procedural, and scripting.
However, there are over 200 programming languages, and several categories overlap. The C programming language is the most ancient of a group of distinct but overlapping languages. C is a procedural language, C++ is an extension, and C# is an object-oriented language created as an extension of C.
What Is the Key Importance of Programming Languages in Ethical Hacking?
Ethical hackers must thoroughly understand programming languages to analyze and modify code. Programming languages can also be used to automate time-consuming operations and detect flaws in software. Finally, the computer systems and platforms under consideration determine the ideal programming languages for ethical hacking.
They are frequently platform-specific and are only utilized with Windows, Mac, or Linux operating systems. Some languages, such as JavaScript, are cross-platform, which means they can run on multiple platforms. Hackers can access saved cookies and perform cross-site scripting using JavaScript code.
Furthermore, open-source platforms provide ready-to-use apps in various programming languages that can be customized. Ethical hackers must create open-source programs and participate in hacking communities to stay current. After all, what is ethical hacking if you don't know what tools and languages hackers employ?
