Abstract: One or more techniques and/or systems are disclosed for presenting members of a shared online space to a user of the shared online space. A relationship value is determined between the user and a member of the shared online space by: determining an interaction value for the user and member relationship based on the user's and member's co-presence in the shared online space; determining a social network value for the user and member relationship based on a number of social network connections between the user and member; and combining the interaction value and social network value. The relationship value is associated with a specified visual representation of the member used in the shared online space, and two or more visual representations of members are scaled in the user's display in the shared online space in order to fit an available screen space, based on the relationship value.

Abstract: A network security policy is represented, stored and edited by using a rule object, a condition object, an action object, and their associations. The condition object is a one-packet-condition object, a repeated-packet-condition object or a linear-packet-condition object. The action object is an alert-action object, a packet-drop-action object, a packet-admission-action object, a session-drop-action object, a session-admission-action object, a session-logging-action object, a traceback-action object or an ICMP-unreachable-message-sending-action object.
