A to Z – Web Vulnerabilities Index – OWASP Standard

Sarcastic Writer May 3, 20217Security

Vulnerability Assessment and Penetration Testing (VA/PT) provides enterprises with a more comprehensive application evaluation than any single test alone. Using the VA/PT approach gives an organization a more detailed view of the threats facing its applications, enabling the business to better protect its systems and data from malicious attacks.

Vulnerabilities can be found in Network or Applications from third-party vendors and internally made software, but most of these flaws aren’t easily found and fixed. Using VA/PT enables to focus on mitigating critical vulnerabilities while the VA/PT continues to discover vulnerabilities.

Suggested Read:

VA/PT involves compromising the system, and during the process, some of the files may be altered. This process ensures that the system is brought back to the original state, before the testing, by cleaning & restoring the data and files used in the target machines. Certain measures and methods are been suggested in this study to determine and prevent exploitation (Attacks) with Manual Pen testing.

In this article, we’ve listed out all Web based Vulnerabilities based on OWASP Standard which is n open community of engineers and security IT professionals whose goal is to make the web safer for users and other entities. The main aim of OWASP Top 10 is to educate the developers, designers, managers, architects and organizations about the most important security vulnerabilities.
