Abstract: The need for secure web applications grows ever stronger the more sensitive, personal data makes its’ way onto the Internet. During the last decade, hackers have stolen enormous amounts of data from high profile companies and social institutions. In this paper, we answer the question of why security breaches still occur; Why do programmers write vulnerable code? To answer this question, we conducted a case study on a smaller software development company. By performing penetration tests, surveys and interviews we successfully identified several weaknesses in their product and their way of working, that could lead to security breaches in their application. We also conducted a security awareness assessment and found multiple contributing factors to why these weaknesses occur. Insufficient knowledge, misplaced trust, and inadequate testing policies are some of the reasons why these vulnerabilities appeared in the studied application.
