Printing exception messages using StackTrace is not secure since it may give detailed information about exceptions that occurred that help the attacker in determining loopholes and security flaws in an application. Instead of using StackTrace it is better to use œMessage to print error messages.


The objectives of this lab are to learn:
.NET Error Handling, Auditing, and Logging
  • The correct way of handling exceptions
  • The correct way of printing exception messages


To be a secure programmer, you must have a good understanding of how to protect your code and make it secure against vulnerabilities.


To work on exceptions in an application, you must be familiar with exception handling.
