"Many Department of Homeland Security (DHS) operations and projects require collaboration and communication amongst affected stakeholders including employees, contractors, federal, state, local and tribal officials, as well as members of the public. One method of effectuating such collaboration is the establishment of an online 'portal' allowing authorized users to obtain, post and exchange information, access common resources, and generally communicate with similarly situated and interested individuals. DHS has written this general privacy impact assessment (PIA) to document these informational and collaboration-based portals in operation at DHS and its components which collect, use, maintain, and share limited personally identifiable information (PII) about individuals who are 'members' of the portal or who seek to gain access to the portal 'potential members.' The Department's mission encompasses a wide variety of activities including emergency response, law enforcement and intelligence, critical infrastructure protection, immigration processing, and research and development of new technologies. In order to facilitate these activities the Department requires contact with the public as well as partners in other federal, state, local, and international governmental organizations (hereinafter known as 'partners'). Part of the Department's interaction with its partners involves the need to establish a means of communication that allows individuals from many different geographic regions to collaborate in a meaningful way. DHS and its components have created varying types of online portals designed to facilitate this collaboration."
