PROTECCION DE DATOS ORACLE

1. The electronic information is simpler to reuse and modify and query, so the future is going towards to only digital data. Sometimes

   • This information can be stored in any database, but not all the database engines meet these requirements.
     • requirements vary to performance, hardware resources, security, user-friendliness, price or others.
       • Oracle database, like any other database, database administrator can grant permissions on any database object to a database to user, so some users have rights to insert data, some others to modify and some other users to modify it, but the DBA user can modify, delete, insert/create, update data or database objects. Securing data stored in database involves not only using strong password or policy, but also adequate access controls over database objects to users.

2. ORACLE DATABASE SECURITY

   • Oracle RDMBS has too many security features which make it an excellent database system for any database application. Data integrity, confidentiality, and availability are well-protected with a properly designed Oracle database
     • Authentication
     • Profiles
     • Privileges
     • Roles
     • Protecting Data Integrity
       • Oracle relational database management system provides several features to ensure data integrity in different cases such system failure, human error, or attacks. These features include redo log files, rollback segments, and LogMiner.
         • All data changes are recorded in at least two redo log files that are maintained by Oracle. In the event of a system failure or data corruption, the last good backup and the redo log should be restored to bring the system back to the state it was before the corruption or data loss.
