When it comes to application security, in addition to securing your hardware and platform, you also need to write your code securely. This article will explain how to keep your application secure and less vulnerable to hacking. The following are the best habits that a programmer can develop in order to protect his or her application from attack: Input data validation Guarding against XSS attacks Guarding against CSRF attacks Preventing SQL Injection attacks Protecting the file system Protecting session data Proper error handling Guarding included files Input Data Validation While designing your application, you should be striving to guard your app against bad input. The rule of thumb to follow is this: don’t trust user input. Although your app is intended for good people, there is always a chance that some bad user will try to attack your app by entering bad input.
