We have learned the importance of securing an application. We became familiar with the possible vulnerabilities, solution for those vulnerabilities, and security scanning tools.
Every start has an end, and thus we have reached the end of the book. We have covered the most important topics that will help you to improve the knowledge of Visualforce development. Further, you can use Force.com resources such as the Force.com discussion board (you can obtain help on technical issues), by using
#askforce on Twitter and https://blogs.developerforce.com.
May the force be with you!
