Web Part galleries are groupings of Web Parts. There are four Web Part galleries: Closed Web Parts, Site Name Gallery, Server Gallery, and Online Gallery. The Online Gallery is a collection of Microsoft MSNBC Web Parts located on the Internet. Allowing users to access the Online Web Part Gallery causes a significant performance hit on the server, due to the server attempting to connect to the MSNBC online gallery. This could result in a Denial-of-Service. The Online Gallery could contain Web Parts from unknown third parties, which could increase the risk of a malicious code execution attack. Preventing users from accessing the Online Web Part Gallery decreases the system's attack surface.
