### USER_ONLY_SECURITY

    public static final short USER_ONLY_SECURITY

  The source security mechanism to use when connecting to this data source.

  Security mechanism options are:
  - USER_ONLY_SECURITY
  - CLEAR_TEXT_PASSWORD_SECURITY
  - ENCRYPTED_PASSWORD_SECURITY
  - ENCRYPTED_USER_AND_PASSWORD_SECURITY - both password and user are encrypted
  - STRONG_PASSWORD_SUBSTITUTE_SECURITY
  The default security mechanism is USER_ONLY SECURITY

  If the application specifies a security mechanism then it will be the only one attempted. If the specified security mechanism is not supported by the conversation then an exception will be thrown and there will be no additional retries.

  This property is currently only available for the DNC driver.

  Both user and password need to be set for all security mechanism except USER_ONLY_SECURITY

USRIDPWD, EUSRIDPWD and USRSSBPWD require a password, USRIDONL is the only security mechanism which does not require password. 1. if password is not available, then security mechanism possible is USRIDONL 2. if password is available,then USRIDPWD is returned.

  Returns:
    upgraded security mechanism if possible

  Parameters:
    `prop` - set to the list of Derby connection attributes separated by semi-colons. E.g., to specify an encryption bootPassword of "x8hhk2adf", and set upgrade to true, do the following:

                     ds.setConnectionAttributes("bootPassword=x8hhk2adf;upgrade=true");

    See Derby documentation for complete list.

### getConnectionAttributes
