In most cases I see that SharePoint users using audiences to secure their web parts. But as most of you know this is really not a security feature. Audiences don't look at security, it will either hide or display the web part based on the audience settings.

If you really need to have Web Parts show based on security what you have to do is use the SecurityTrimmed control. All you have to do is open your default.aspx in your SharePoint Designer and add the following code snippet.

<Sharepoint:SPSecurityTrimmedControl runat="server" PermissionsString="ManageWeb">
 <WebPartPages:WebPartZone id="g_CC57BF5FF56740B099B0728E5C262566" runat="server" title="Secure Zone">
    </WebPartPages:WebPartZone>
    </SharePoint:SPSecurityTrimmedControl>

This will add a Web Part Zone named SecureZone to your default.aspx page which will allow you to add web parts that will only be displayed to Administrators. The way you decide who gets to see the Web parts is by changing the value of the PermissionsString. In this case it is set to ManageWeb which is what only administrators have. So the web parts that are added to this web part zone will one be displayed to administrators.

Some of the other Permission Strings are as follows:

ManagePermissions
ViewUsageData
ManageSubwebs
ManageWeb
AddAndCustomizePages
ApplyThemeAndBorder
ApplyStyleSheets
CreateGroups
BrowseDirectories
CreateSSCSite
ViewPages
EnumeratePermissions
BrowseUserInfo
ManageAlerts
UseRemoteAPIs
UseClientIntegration
Open
EditMyUserInfo

I'm not sure if you've run into this when you're developing custom webparts or adding 3rd party webparts to a page but this happens to me quite often, I get an error stating that the page cannot be displayed and I right of way I know it's a web part I added to the page that's causing the issue but I can't get to the page to delete the web part. I don't want to open SharePoint designer either, so how do you delete the web part with the browser if you can't accesss the page?

Use the following URL on any SharePoint site to see the webparts you have installed on your SharePoint page

/_layouts/spcontnt.aspx?&url=[your_page_url_goes_here] 

So if  the page you're having issues with looks like the following

http://www.yourserver.com/site1/default.aspx

To see the web parts on that page you would use the following link

http://www.yourserver.com/_layouts/spcontnt.aspx?&url=/site/default.aspx

When you get to that page you'll see that you can Close, Reset or Delete web parts on the page that you specified.

Hope this helps!
