Overview of the Security Tab

The Security tab has settings to control various aspects of your survey such as who can take the survey and what to do with repeat responses.  This page describes the following settings:

  • Restrict access to respondents with an IP address in the range
  • When a respondent takes your survey a second time
  • Identify repeat respondents by
  • Response limit settings
  • Email questionnaires to me as they are completed

Tip: The default settings on this tab are appropriate for most users.

Restrict access to respondents with an IP address in the range

This setting allows you to specify an IP address range that will allow access to your survey.  Every computer on the internet has an IP address that is used to identify it.  By default, all IP addresses are allowed access to your survey, but you can specify a range of IP addresses that should have access instead.  This option is most useful when conducting employee surveys where you want to ensure that only individuals inside your company have access to your questionnaire.

When a respondent takes your survey a second time

This setting controls what happens to your results when someone comes back to the survey after they have already submitted a response.  For more information about how Vista knows if a person has already submitted a response, see Identify repeat respondents by below.

You can use these options to prevent ballot-stuffing in your survey, i.e. preventing people from intentially submitting multiple times in order to skew results.  The following are the options in this group:

  • Refuse to start the questionnaire - When a user tries to take the survey a second time, they will receive a message saying they have already responded to the survey and they are not allowed to continue.
  • Allow the respondent to take the survey again but don't save the results - A user will be able to take and submit the survey again but their subsequent results will not be saved (although it will appear to the user that they are). 
  • Allow the respondent to take the survey again and overwrite the first set of results - A user will be able to take and submit the survey again but each result will overwrite the previous result.
  • Allow the respondent to take the survey as many times as they want and keep all results - All responses from the respondent will be kept even if it is a repeat response.  This is the default setting.
  • Require login and allow the respondent to edit past answers - Users will be asked to create a login account before taking the survey.  They can use the account to edit their answers.  For more details, see the article Requiring a login to edit answers.

Identify repeat respondents by

This option is used to set the way Vista identifies a respondent when enforcing the rule you specify for repeat responses (above).  The default and recommended setting is Persistent Cookie which will use a unique, persistent cookie written to the user's computer to identify the user on return trips.  However, if the respondent has disabled cookies, Vista will not be able to prevent respondents from taking your survey again.  Using the respondent's IP address as an identifier is more restrictive than cookies; however, many company networks are set up to allow users to share addresses. Also, with some ISPs, a user could have a different IP address each time they log in.

Note that if you send your email invitations through Vista, this selection does not apply because Vista will be able to track the respondent automatically from the unique link in the email.

Response limit settings

Use this option to limit the number of responses allowed for this survey, either by specifying a maximum number of allowed responses (e.g. accept only the first 2000 responses) or by specifying a maximum date (e.g. accept responses up to Dec 15, 2005). Click the Change link to change the response limit settings for a survey.

Email questionnaires to me as they are completed

Use this option to have each completed questionnaire emailed to you as it becomes available. This will allow you to manually review each respondent's answers. The email message contains a hyperlink you can click to delete the respondent's answers if you deem them to be insincere. This feature is also useful if you are using the questionnaire to collect periodic user data that needs manual processing.

You can enter multiple email addresses in this field separated by commas.

Note that if you want to send a copy of the completed questionnaire to the respondent taking the survey, you can use a Send Email Question type.
