Why you should care

[/vc_column_text][vc_column_text pl=”0″ pr=”0″ pt=”0″ pb=”0″]

When an exception occurs during programming, it is usually caught in a catch block. Empty catch is when an exception occurs but the program fails because nothing occurs. As a result, they are a common source for obtaining errors in the code, and then executing these errors. It is also inefficient since it catches nothing and executes nothing.

Business Impacts

Empty catch blocks are considered a risk from a business perspective as it can pose security issues. Risks can involve programmers and/or the company are unaware of the security being compromised.

CAST Recommendations

CAST Recommends enforcing a Style Guide for the company that strongly suggests avoiding the use of empty-catch blocks to solve a problem in the code.  Instead teams should be encouraged to collaborate and work on the problem together through communication.[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/2″][vc_column_text pl=”0″ pr=”0″ pt=”0″ pb=”0″]

How we detect

[/vc_column_text][vc_column_text pl=”0″ pr=”0″ pt=”0″ pb=”0″]

This code insight shows that catching an exception provides robustness treatment or error management. A catch doing nothing can masks an error, allowing the program to pursue and ignore the problem.
