By using specific application security testing methods, security professionals can identify and remediate application vulnerabilities early in the software development life cycle.
Applications help facilitate nearly everything we do in our world today. Banking, shopping, travel, healthcare, and other crucial services all rely on underlying applications and software packages to securely process and transmit data.
Application security testing is a critical component of protecting data integrity, and software developers rely on a variety of common automated application security testing methodologies. These approaches each have pros and cons, but when integrated into the development process and combined with penetration testing, they can support a comprehensive approach to evaluating application security.
New applications, old questions
Despite the decades of advancement in application development and testing technologies, many of the same concerns and challenges that developers had in the past still exist. Examples include:
- Can the integrity of source code be validated?
- Can user input be sanitized?
- Are users prevented from accessing other users’ confidential information?
- Will the application remain scalable?
- What happens when users interact with the application in unanticipated ways?
- How can errors be communicated to users without giving away valuable information for an attacker?
