List three of the steps you should take to close potential holes against SQL injection attacks.
What will be an ideal response?
Tighten database authentication and limit table access. Always require password access to the database, and never leave default usernames set up during installation. Most attackers are familiar with the default administrative username , so make sure to change it.
Use stored procedures to eliminate passing any SQL commands to the database.
Validate all user entries to make sure they are formed properly. Perform this validation in several places if necessary. There should be two layers of validation: form-level validation at the browser before the Web page is submitted and server-level validation when the information reaches the server for processing.
Place the Web server and database server in a network DMZ.
Use nonstandard naming conventions in database construction. To thwart attackers, you should make database names, table names, and field names difficult to guess.
Configure a custom error message that does not reveal information for attackers to exploit.

``` static void doQuickSort(int array[ ], int start, int end) { int pivotPoint; pivotPoint = partition(array, start, end); doQuickSort(array, pivot+1, end); doQuickSort(array, start, pivot-1); } ``` A) will correctly sort the array if the partition method is written correctly B) will give incorrect results because the two recursive calls are called in the wrong order C) will sort the array in descending rather than ascending order D) will be terminated by the system for making too many recursive calls
