Use Strong Input Validation The right approach to input validation is to check input against a ist of known good values Good input validation does not attempt to check for specific bad values It s like having an invitation-only party If you want to make sure only invited guests get in, make a guest list and check against it at the door Don t try to make a list of all the people who aren t invited Checking against a list of known good values is called whitelisting When the set of possible input values is small, you can use indirect selection to make the whitelist impossible to bypass Indirect selection is at the top of the heap when it comes to input validation At the bottom of the heap is blacklisting: attempting to enumerate all the possible unacceptable input Indirect Selection In general, the less leeway an attacker has to provide unexpected input to the program, the better For that reason, the best way to validate input is with a level of indirection: Create a list of legitimate values that a user is allowed to specify, and allow the user to supply only the index into that list Now, instead of validating a potentially complex piece of input, the program only needs to check to make sure that the user supplies a legitimate index With this known good approach, application logic never directly uses input the user provides This form of input validation isn t always practical, but it is ideal for situations in which a user is selecting from among a list of choices Use selection values that cannot be easily mistaken for the data they protect This will eliminate any later temptation to use the values directly Example 59 gives a program that limits access to old UNIX-style games By funneling would-be gamers through a launcher program, access to games on the system is controlled centrally Of course, such programs should expect to come under a variety of attacks, ranging from attempts to gain unauthorized access to efforts designed to use the launcher program to modify protected saved game files The program works by reading the name of the game from standard input Note that the indirect selection does not permit the user to specify a full path to the executable, so any future attempt to use the input directly will likely cause the program to fail.
