Excel Services Security Best Practices – Overview Of Excel Services Security

The when designing security strategies for Excel Services it involves learning about holistic SharePoint security, user authentication, communication for servers, and the authentication of external data. All of these areas must be covered before implementation so you can make well informed decisions. There is a great deal more to consider with Excel Services than just security however. When it comes to deploying SharePoint 2010 and its associated features, you need to take many different considerations and evaluate them. One of the many elements that can be of benefit to you is the Excel Services Application. It is one of the platforms that is part of SharePoint 2010. The function of Excel Services works with SharePoint Server 2010 to offer security, control, and management for the various Excel workbooks that are part of that enterprise. This type of application is a server that allows for performance and security to be key issues addressed. It can be deployed within workbooks or work with them so that the various components such as PivotTable reports and charts can be used for dashboards within any organization. This allows a user to take advantage of calculations that are associated with a server side Excel spreadsheet.

From there custom applications can be determined. Users have the option of locking workbooks so that they can have more security over their private data and property. This makes it possible for the data in a workbook to be protected at a higher level while they are on a server. It also allows for the data to be refreshed and recalculated through the Excel Services Application.

There is no denying that security is very important for any such component. There are several elements that you need to consider when it comes to the planning for your environment. You want it be one that has high security for the workbooks that will be placed on a server. When designing the Excel service security a plan should be developed to manage the security of the workbooks and the security of server that they are placed on. With the help of Excel Services Application you will be able to have complete control over the process and how everything is displayed for the Excel workbooks. You get to control how the workbooks will be opened on the server. You get to control who will be authorized to open them and what elements that they get access to from those workbooks. Understanding the security and the authentication settings you can choose from with Excel Services Application is very important.

You will need to consider all of this information before you move forward with deployment. The guidance offered here in these materials will ensure you get the most benefit from Excel Services Applications. At the same time it will ensure that your workbooks are very secure on the server.The security model is based on the concept of ensuring the data is in quality form, that the administrator is able to centrally manage the resources being shared, and that the intellectual property of the workbooks is maintained. In order for this to happen you will need to specify something things in Excel Services. Trusted data connection libraries are SharePoint document libraries with .odc files. Those files are used to offer a centrally managed connection with external data sources. Rather than allowing for the connections to be embedded, they can be configured through Excel Calculation Services for all data connections with those .odc files. The .odc files are stored and the connection must have trust before the workbooks can be accessed through Excel Calculation Services. Trusted data providers are the external database where the Excel Calculation Services can be configured. They have to be able to trust so that the data being processed is able to successfully connect to the workbooks. The connection will only be attempted by Excel Calculation Services when there is a trusted data provider in place. Trusted file locations are document libraries in SharePoint are the trusted file locations. They have to be trusted before the Excel Calculation Services will be able to access them. It is important to understand that Excel Calculation Services is only able to open workbooks that are stored in trusted files.

The default setting for a cross domain workbook and data connection isn’t allowed to occur. If you want to have the workbooks in trusted file locations that can be accessed across the web part domains you have to run the Windows PowerShell. The web pages that are requested and the workbooks have to be on the same farm. When you open up a workbook in Excel Calculation Services, there will be a temporary file stored in the %TEMP% folder. This will be located on the application server where the Excel Calculation Services is running.
