How To Protect Your database

The clauses of the CREATE DATABASE statement used for specifying the passwords for users SYS and SYSTEM are:

- USER SYS IDENTIFIED BY password
- USER SYSTEM IDENTIFIED BY password
If not specified, these users are assigned the default passwords change_on_install and manager, respectively. A record is written to the alert file indicating that the default passwords were used. To protect your database, you should change these passwords using the ALTER USER statement after database creation.
