Vulnerability discussion

Separation of duties is a prevalent Information Technology control implemented at different layers of the information system including the operating system and in applications. It serves to eliminate or reduce the possibility that a single user may carry out a prohibited action. Separation of duties requires the person accountable for approving an action not be the same person who is tasked with implementing the action. This requirement is intended to limit exposure due to user accounts being used to operate from within a privileged account or role. Limiting the access and permissions of privileged accounts to the minimum required, reduces exposure if the account is compromised and provides forensic history of activity when operating from these accounts. This policy limits the Farm Account privileges in AD. However, default permissions for this account are configured by the SharePoint Products Configuration Wizard during product installation. This account is referred to during the installation as the "Database Access" account. By default, the account is used as the service account for the SharePoint Timer Service and the SharePoint Central Administration Web Site Application Pool. These settings should not be changed. Furthermore, this account should not be used as the service account for non-privileged services, applications, or application pools.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
