Description
Remote access is any access to an organizational information system by a user (or an information system) communicating through an external, non-organization-controlled network (e.g., the Internet). Examples of remote access methods include dial-up, broadband, and wireless. Remote network access is accomplished by leveraging common communication protocols and establishing a remote connection. These connections will typically occur over the public Internet, the Public Switched Telephone Network (PSTN), or sometimes both. Since neither of these Internetworking mechanisms are private nor secure, if cryptography is not used, then the session data traversing the remote connection could be intercepted and potentially modified. Cryptography provides a means to secure the remote connection to prevent unauthorized access to the data traversing the remote access connection, thereby providing a degree of integrity. The encryption strength of a mechanism is selected based on the security categorization of the information traversing the remote connection.

Review the SharePoint server configuration to ensure cryptography is being used to protect the integrity of the remote access session. In SharePoint Central Administration, click Application Management. On the Application Management page, in the Web Applications list, click Manage web applications. On the Web Applications Management page, verify that each Web Application URL begins with https. If the URL does not begin with https, this is a finding. If SharePoint communications between all components and clients are protected by alternative physical measures that have been approved by the AO, this is not a finding.

Fix Text (F-65349r2_fix)
Configure the SharePoint server configuration to use cryptography to protect the integrity of the remote access session. Open IIS Manager. In the Connections pane, expand Sites. Click the Web Application site. In the Actions pane, click Bindings. In the Site Bindings window, click Add. In the Add Site Binding window, change Type to https, and select the site's SSL certificate. Click OK, and then click Close.
