A very powerful part of SharePoint is the ability to share information with anyone. Anyone meaning the entire world. You can publish RSS feeds, share documents etc. If you want to limit who "anyone" is they will need an asurite account to sign in and see your site. If you want to allow anyone to see only part of, or your entire site, keep reading.

Remember, this makes some of your site accessible to anyone in the world. Be careful to only open content that is not sensitive in any way.

1. Send a request to spadmin@asu.edu to have the feature turned on. Be sure to say you would like to allow anonymous access and include the site collection URL. After we let you know our part is done, continue with the following steps.
2. Go to the site on which you want to enable anonymous access and click the Site Actions menu.
   1. On the Site Actions menu, click Site Settings
   2. On the Site Settings page, in the Users and Permissions section, click Advanced Permissions.
   3. On the Permissions page, on the Settings menu, click Anonymous Access. The settings for anonymous access lists three options:
   4. Entire Web site Select this option if you want to enable anonymous access for the entire Web site.
   5. Lists and libraries Select this option if you want to limit anonymous access to only specific lists or libraries on your site.
   6. Nothing Select this option if you want to prevent anonymous access from being used on your site.
   7. Click OK.
   8. At this point, your site is configured for anonymous access based on the options that you have selected.
3. If you selected Lists and Libraries above, enable access on those designated lists.
   1. Go to the list itself and click Settings, List Settings, and Permissions for this list.
   2. Click on Settings, and Anonymous Access.
   3. Select the appropriate level of access.
4. If you selected Entire Web Site, remove access to lists that contain sensitive information.
   1. Go to the list itself and click Settings, List Settings, and Permissions for this list.
   2. Click Actions, and Edit Permissions.
   3. Click on Settings, and Anonymous Access.
5. Remove the permissions as appropriate. If you take out all selections, users must sign in to see this list.

Consider these best practices:

• If possible, create a sub site with all your anonymous access content to help everyone know when they are posting something in a public place.  This also simplifies your security model, you can allow access to the entire site and you avoid having to customize several lists.
• Be careful with new lists.  If the default behavior for your site is to allow anonymous access, you might let something out you don't intend.  It is best to use the Lists and Libraries option described above and then actively turn on access for all new lists that need it. 
• Place a large Sign In link if your ASU users will navigate directly to that page.  If they will only see it after starting at some other part of the site this is not an issue as they will already be signed in.  You can use SharePoint designer and copy the sign in / welcome link at the top of any page.
• Test your site to make sure it is doing what you think it is doing.  Try to load several different pages while not signed in.
