Integrity Monitoring Service (IMS)
The SAVVIS Integrity Monitoring Service (IMS) provides notification and alerts when specified files residing on a host computer are changed. Alerts are then responded to 24/7 by SAVVIS’ Managed Security team. Host-based software computes a cryptographic hash of the data content of a directory or file, and forwards that hash to an integrity server at a secure SAVVIS facility. The integrity server compares that hash with previously stored hash values for that same file — an integrity comparison. Any detected difference in hash values means that the directory or file has changed. IMS is best used to monitor files and directories that tend to remain static over time.
