Application security testing involves a complete analysis of the application. The purpose is to identify weaknesses, vulnerabilities and other security issues.
Application security testing is recommended on a regular basis, as the threats are constantly changing and new functionality gets added to the application. How often you should perform a security test, depends on the number of changes made in the application in the course of a year.
On a general basis, Encripto recommends conducting a full application security test once a year. In addition to this, we recommend you to conduct smaller security tests when launching revised versions or new functionality.
