No sensitive information is presented to the user when an error occurs. For example SQL injection is much tougher to successfully pull off without some healthy error messages. It lessens the attack footprint and our attacker https://www.owasp.org/index.php/Error_Handling would have to resort to use “blind SQL injection” which is more difficult and time consuming. A well-planned error/exception handling strategy is important for three reasons: Good error handling does not give an attacker any information which is a means to an end, attacking the application A proper centralised error strategy is easier to maintain and reduces the chance of any uncaught errors “Bubbling up” to the front end of an application. Information leakage can lead to social engineering exploits. Some development languages provide checked exceptions which mean that the compiler shall complain if an exception for a particular API call is not caught Java and C# are good examples of this. Languages like C++ and C do not provide this safety net. Languages with checked exception handling still are prone to information leakage as not all types of error are checked for.
