Roster data is workforce listing information used to manage employees, teams, roles, and assignments. It may include names, job titles, departments, managers, locations, or identifiers that connect a person to an account or business unit.
In cyber security, this information can help defenders manage access and investigate activity, but exposure may also help attackers map an organization and identify valuable targets. Combined with login logs or federation details, roster data can reveal how people and accounts relate to teams and access systems. Organizations should limit collection and access, protect exports, and remove or update records when they are no longer needed.
