Why are vulnerable sites valuable to newbie hackers?

By any chance, it is not a secret that such vulnerabilities leave you open to attack by all the bad guys. The thing that makes it worse is that in their web app vulnerability report 2020, web company Acunetix says that around 63% of apps and perimeter network security technologies carry medium severity vulnerabilities and the other 26% have high ones.

Though the data is lower than what has been reported before to be honest it is still too high.

A developer is responsible for creating, designing and testing new sites, apps, OS and other technologies. Doing this successfully requires:

  1. Integrating best practices and approaches of cybersecurity in the development structure and processes.
  2. Understanding which development languages or platforms are most vulnerable.
  3. And what can be done to make them secure?

This means that you need to have the required knowledge and skills to identify and mitigate such vulnerabilities. And to keep such attributes up to date, you need to have an awareness of trends in the cyber-crime industry and also real-world approaches that are being used by criminals. This is where using vulnerable sites and apps comes into action.

The question is from where you can find them? Well, don’t worry as you have dropped at the right place. Follow through to have all the answers
