+Libc functions that are banned or to be used with caution
+---------------------------------------------------------
+
+Below is a list of functions that present security risks and either must not be
+used (Banned) or are discouraged from use and must be used with care (Caution).
+
++------------------------+-----------+--------------------------------------+
+| libc function | Status | Comments |
++========================+===========+======================================+
+| ``strcpy, wcscpy`` | Banned | use strlcpy instead |
+| ``strncpy`` | | |
++------------------------+-----------+--------------------------------------+
+| ``strcat, wcscat`` | Banned | use strlcat instead |
+| ``strncat`` | | |
++----------------------- +-----------+--------------------------------------+
+| ``sprintf, vsprintf`` | Banned | use snprintf, vsnprintf |
+| | | instead |
++---------------------- -+-----------+--------------------------------------+
+| ``snprintf`` | Caution | ensure result fits in buffer |
+| | | i.e : snprintf(buf,size...) < size |
++------------------------+-----------+--------------------------------------+
+| ``vsnprintf`` | Caution | inspect va_list match types |
+| | | specified in format string |
++------------------------+-----------+--------------------------------------+
+| ``strtok`` | Banned | use strtok_r or strsep instead |
++------------------------+-----------+--------------------------------------+
+| ``strtok_r, strsep`` | Caution | inspect for terminated input buffer |
++------------------------+-----------+--------------------------------------+
+| ``ato*`` | Banned | use equivalent strto* functions |
++------------------------+-----------+--------------------------------------+
+| ``*toa`` | Banned | Use snprintf instead |
++------------------------+-----------+--------------------------------------+
+
+The `libc` component in the codebase will not add support for the banned APIs.
