Since the commencement of existence, every element was needed to be protected or secured for peace. There is no exception in the elements that are needed to be secured, which includes human beings as well. Human beings face danger and fall victim to crimes in many ways. One of which is a cybercrime. In day to day life, we're all depending on the internet and the applications we use on the internet. These apps can be used to cause harm by any means to its user. Moving forward, a web application is simply an application that is used mainly on a browser to perform a task over the internet depending on the user's needs. These applications are created using various techniques and languages with the hope of making it efficient for users to perform a specific task. As we know, every coin has 2 sides, so does the internet. The internet is home to great knowledge and simultaneously, home to different crimes we often refer to as "cybercrime". These web applications can be used for cybercrime activities. It could be any activity like stealing money from someone, stealing their identity, corrupting or destroying a computer system, stealing some sensitive data, and so much more. Therefore, it is necessary to secure ourselves from such crimes and prevent them from harming us.
Since we all know that nothing in existence is perfect, neither is a computer system and everything that is inside it. Web app security refers to the amount of protection or the total layers of protection applied on a web application. Whilst, Web Application Pentesting means performing various methods or techniques on an application to draw out or highlight its vulnerability or a number of vulnerabilities with an aim to patch those weaknesses up in order to make that application secure and efficient. Penetration testing (often referred to as "Pentesting") is a technique of testing various nodes present on the internet to find out the flaws and strengthen them up.
Well, the entire existence is flawed regardless of what it is. These flaws can sometimes lead up to something serious which ends up in the suffering of human beings. The suffering could be either emotional or physical. So, the web applications are no exceptions. The thing that differs it from every other flawed entity is that these flaws can be removed and strengthened up and for that, SECARMY will take up the responsibility. These flaws are necessary to be sealed up because they can be used in a number of ways to harm a user either virtually or physically. Let's take up a few instances of how and what various harms can an attacker cause a user using these flaws/vulnerabilities/weaknesses.
There are many tools that exist that can be used to analyze and a system's security and find out vulnerabilities which can be used as a path to intrude into a system to cause destruction. Such tools can be used to secure a system but also at the same time, they can create a serious threat. These include a huge number of tools like "Metasploit" which is one of the most powerful and notorious tools that can be used to withdraw out the flaws and use them as an exploit in a system. Metasploit has over 2000 catalogued vulnerabilities and even if any 1 of those vulnerabilities is present in a system, then that system is as good as a destroyed one. "John the Ripper" is another tool which is considered to be one of the fastest password cracking tools and can be used to crack your Wi-Fi password, system password, password protected files, encrypted files and so much more without much effort. Another one of the most powerful tools is "Maltego" which can be used for open-source intelligence and digital forensics. An attacker can use this tool to recover all the sensitive data that you've deleted or hidden that you didn't want anyone to get hands on. An attacker can trace the bits of evidence of that file's existence and can reach its current location and cause you to harm using those files. There are many more tools that an attacker can use to attack you or the ones close to you in many ways like phishing scams where an attacker can lure you towards using a website or an application that might seem genuine but is not and is used to obtain sensitive information, identity theft scams where an attacker can perform a criminal act and impersonate you while doing that, online harassment where an attacker can harass or harm someone emotionally which might end up in a case of suicide, and so much more threats like these.
In conclusion, Web Application Pentesting is necessary so as to find out all the flaws and secure them using various services provided by SECARMY in order to lead a safe and peaceful life; far from any cyber threat which might be quite serious. A secure WebApp can help a user to perform tasks very efficiently without facing any serious threats or dangers.
