Network topology security

The sense of presence of the participants is the most traditional type of awareness information provided by the CES. This information leads to the current network topology security state and activities, since the knowledge of who is active facilitates the identification of who is working, where the work is being made and if it is being made simultaneously or concurrently. Because of what can be inferred by the sense of presence it is closely related to the workspace awareness regarding the knowledge of who and where the participants are interacting with the group, and it is an essential type of information that can be used during group work.

The information about the sense of presence and workspace awareness is provided by awareness devices that show details about the individual actions of the participants. The devices offer the opportunity to understand the meaning of the actions and can be used to coordinate activities and enhance the communication. In CES, the visual awareness devices that provide information about the sense of presence and workspace awareness are called awareness widgets and are designed as elements of the user interface.
