When it comes to the security and safety of your electronic devices like your phones, laptops and PCs it is important to evaluate the system and check for vulnerabilities in them as well. This whole process of checking for vulnerabilities in the system by using various malicious techniques is known as penetration testing or ethical hacking in which they simulate a hacking attack on their own system to explore the weaker points in the system and soon after knowing all that, they strategize a good plan so as to strengthen the system so that all of those problems can be solved as soon as possible. The main focus or emphasis we would like to bring on is on the point that this attack is authorized and simulated unlike actual hacking attacks that happen fairly commonly in this day and age.
The main reason for even going to this length to test this is so that the important data on computers is not leaked to people who can misuse it or just any kind of hackers to begin with. This unauthorized hacking and access to the data present in the system can lead to security relapses and other things like sensitive information can also be leaked which can entirely mess up, this is important because while having a presence on the internet means that you will be providing your personal information to some of the websites that you purchase things from and if that website is under attack then there is high chance that your info might be leaked in the process as well, that is why ethical hacking is very important.
