Bugs and viruses in software have become a common topic now. Almost every person whether related to this field or not has some knowledge about viruses and their harmful effects. Where some people that no measures are taken to prevent these unwanted guests from getting into software, a lot of people are aware of the preventive measures taken. Did you know every bug and virus is dealt with based on different severity levels defined? Every penetration testing company works according to these pre-defined severity levels of security bugs. Here are the severity levels of the bugs known in the testing industry.

Blocker Level Bugs

This is the top-most level on the severity chart of the bugs. Blocker level bugs are the most feared as they are known to even block testing technologies and tools by crashing down the whole process. This crashing of the application can either happen in a particular testing environment or in all environments as well.

Critical Level Bugs

Although these are one level down than the blocker bugs but that does not mean they are any less harmful. These directly harm the security of the software and can lead to loss of data, program crashing, and even some serious damages. These bugs can easily disable the app’s main functions making them permanently crippled.

Major Level Bugs

The third level of bugs defined by every penetration testing company is called major level bugs. These bugs are known for affecting major aspects of definite testing and can have a negative influence on subsequent checks too. These bugs are somehow easier to catch as compared to critical and blocker bugs.

Minor Level Bugs

This is the lowest level of the bugs and the majority of companies or the developers do not fear these bugs. They are easiest to catch and solve as they do not influence the testing process or the basic functions of the app. These bugs can even be seen and fixed by developers.

Conclusion

It is extremely necessary for a penetration testing company to divide the found bugs on the basis of severity levels. It helps them in prioritizing the bugs so they can solve the most serious ones first and foremost before they can harm the application in ways that can’t be fixed. Moreover, it also helps a lot in reporting as the tester can define and write about bugs in a better way helping the developers understand issues and fix them properly.

A lot of testing companies desire to hire testers who have good knowledge about these severity level distribution of bugs as it eases the process and makes it faster too. However, the sad reality is that most of the testers fail to define bugs based on their severity levels hence, making the testing task even harder and more time-consuming. So it is extremely necessary for every tester to have knowledge about these severity levels for every bug as they can help them make their own task easier, faster, better, and produce great results.
