Secure coding

Defects, bugs and logic flaws are consistently the primary cause of commonly exploited software vulnerabilities.

By identifying the insecure coding practices that lead to these errors and educating developers on secure alternatives, organizations can take proactive steps to help significantly reduce or eliminate vulnerabilities in software before deployment.

[2] Some scholars have suggested that in order to effectively confront threats related to cybersecurity, proper security should be coded or “baked in” to the systems.

To fix this unsafe program, use strncpy to prevent a possible buffer overflow.Another secure alternative is to dynamically allocate memory on the heap using malloc.In the above code snippet, the program attempts to copy the contents of src into dst, while also checking the return value of malloc to ensure that enough memory was able to be allocated for the destination buffer.

Below is a function in C++ which attempts to confirm that the sum of x and y is less than or equal to a defined value MAX: The problem with the code is it does not check for integer overflow on the addition operation.
