Note:
After the Recovery Appliance has been deployed, the installation process disables all root SSH keys and expires all user passwords as a security measure for your system. If you do not want the SSH keys disabled or the passwords expired, advise the installation engineer before the deployment.See Also:

Oracle Exadata Deployment Assistant (OEDA) implements a default password policy on Oracle Exadata Database Machine.
The last step of OEDA, "Secure Oracle Exadata Database Machine", implements the following password requirements:
- Dictionary words are not valid or accepted.
- Character classes for passwords are uppercase letters, lowercase letters, digits, and special characters.
- Passwords must contain characters from all four character classes. Passwords using only one, two, or three character classes are not allowed.
- The minimum length of a password is eight characters.
- Pass-phrases are allowed. A pass-phrase should contain at least three words, be 16 to 40 characters in length, and contain different character classes.
- A new password cannot be similar to old passwords. There must be at least eight characters in the new password that were not present in the old password.
- A maximum of three consecutive characters of the same value can be used in a password.
- A maximum of four consecutive characters of the same character class can be used in a password. For example,
abcde1#6B
cannot be used as a password because it uses five consecutive lower case letters.
Default Security Settings Enacted by OEDA
Oracle Exadata Deployment Assistant (OEDA) includes a step to increase hardware security on Recovery Appliance.
The last step of OEDA implements the following security policies:
- For all newly created operating system users on the compute servers and storage servers, the following password-aging values are set:
- The maximum number of days for a password is 60 days.
- The minimum amount of time between password changes is 24 hours.
- The number of days of alerts before a password change is seven days.
- All non-root users must change their password at their next log in.
- An operating system user account is temporarily locked for 10 minutes after one failed log in attempt.
- An operating system user account is locked after five failed attempts.
-
For the
root
user, SSH equivalency is removed for all compute servers and storage servers. -
The following permissions are set by OEDA:
- The Automatic Diagnostic Repository (ADR) base directory,
$ADR_BASE
, has SUID (Set owner User ID) on thediag
directory and its sub-directories. - The
celladmin
user group has read and write permissions on the$ADR_BASE
.
- The Automatic Diagnostic Repository (ADR) base directory,
