File-integrity monitoring (FIM) systems check for changes to critical files, and notify when such changes are detected. There are both off-the-shelf and open source tools available for file integrity monitoring. If not implemented properly and the output of the FIM monitored, a malicious individual could alter configuration file contents, operating system programs, or application executables. Such unauthorized changes, if undetected, could render existing security controls ineffective and/or result in cardholder data being stolen with no perceptible impact to normal processing.
