High Quality Content by WIKIPEDIA articles! Dazuko (Dateizugriffskontrolle germ. File Access Control) project provides a device driver for Linux allowing third-party (userland) applications to execute file access control. It was originally developed by Avira GmbH (formerly known as H+BEDV Datentechnik GmbH) to allow on-access virus scanning. Other uses include a file-access monitor/logger or external security implementations. It operates by intercepting file access calls and passing the file information to a third-party application. The third-party application then has the opportunity to tell the device driver to allow or deny the file access. The third-party application also receives information about the access event, such as accessed file, type of access, process id, and user id.
