In this video, the presenter demonstrates some new features in Quest I.T security search. The customizable grid columns allow users to create search result layouts with specific event fields of interest. The newly added "current user" parameter enables users to search for events where they are the initiator. This can be useful for delegating responsibility to end users to investigate certain events. Additionally, the presenter shows how to use a combined search to investigate who, besides administrators, had access to a specific file.
