This article discusses the security of Firebird database files and in particular access to the metadata stored in those files. It has been written in response to frequent questions on the Firebird lists access to a database file there is no effective way to prevent that user from reading all data (and metadata) within that file.  “Adequate” security is dependent on the level of security required for a
