For example, an Oracle database has the same user categories as Linux-owner, group, and other users. 1-execute permission granted to the user categoryĪll modern databases have built-in file security features.2-write access granted to the user category.4-read access only granted to the user category.0-access not granted to the user category.Linux returns one of four access codes when access is requested to a file: The owner can grant or deny read, write, and execute permissions for each user category. In Linux, there are three categories of users: owner, group, and other users. The Linux security model is based on the robust security model used by UNIX systems. If there is a match, a handle is returned to the thread and authorization is granted. Windows compares the permissions and information requested by the thread access token with the information in the security descriptor of the file or directory. Access is managed by the same access control model that manages all other securable Windows objects. How File Security Enables File Integrity Monitoringįile Integrity Monitoring solutions rely on file security features built into modern operating systems and databases. Reactive auditing-forensic examination of files after security incidents.Active monitoring-live monitoring of changes to files based on rules or behavioral analysis. If it determines that a file has been tampered with, updated, or corrupted, it generates an alert to enable further investigation and action. You can use FIM to inspect operating systems (OS), databases, and application software files.Ī FIM solution establishes a trusted, known baseline for each file, and performs audits of all changes to files, by comparing them to this baseline. The term FIM refers to IT security technologies and processes used to check whether certain components were corrupted or tampered with.
