Taint Synonyms and Antonyms

To corrupt

Each system component cannot fully validate input. The concept of taint, therefore, is to mark particular inputs as having been entered by the user. Then, only a thorough deconstructing and reconstructing of the information can remove the taint. Although some programming languages such as Perl automate this kind of tracking, other languages such as C need manual tracking. Each system component cannot fully validate input.

Related to vulnerabilities used by crackers to break into systems; weak or insufficient validation of user input. Far too often, programmers expect that users will enter proper input. This leads to another problem: Programmers tend to omit critical system components to check for malicious users taking special care to craft input designed to exploit a system.The issue with input validation is that software system components reading and interpreting the input just do not know enough to properly validate it.
