- Taint_checking abstract "Taint checking is a feature in some computer programming languages, such as Perl and Ruby, designed to increase security by preventing malicious users from executing commands on a host computer. Taint checks highlight specific security risks primarily associated with web sites which are attacked using techniques such as SQL injection or buffer overflow attack approaches.The concept behind taint checking is that any variable that can be modified by an outside user (for example a variable set by a field in a web form) poses a potential security risk. If that variable is used in an expression that sets a second variable, that second variable is now also suspicious. The taint checking tool proceeds variable by variable until it has a complete list of all variables which are potentially influenced by outside input. If any of these variables is used to execute dangerous commands (such as direct commands to a SQL database or the host computer operating system), the taint checker warns that the program is using a potentially dangerous tainted variable. The computer programmer can then redesign the program to erect a safe wall around the dangerous input.Taint checking may be viewed as a conservative approximation of the full verification of non-interference or the more general concept of secure information flow. Because information flow in a system cannot be verified by examining a single execution trace of that system, the results of taint analysis will necessarily reflect approximate information regarding the information flow characteristics of the system to which it is applied.Taint checking is a black-listing approach as it asserts that certain values are dangerous. The white-listing equivalent is trademarking.".
