NagVis is a visualization addon for the well known network managment system Nagios. NagVis can be used to visualize Nagios Data, e.g. to display IT processes like a mail system or a network infrastructure. Key features are: * Display of single Hosts and Services * Visualize a complete Host- oder Servicegroup with one icon * Display the state of a Host dependent on the state of its services (“recognize services”) * Display only the real problems (“only_hard_states”) * Define Sub-Map icons wich represent a complete NagVis Map of Hosts/Services/Groups in one icon (drill down) * Visualization/Documentation of complete IT Processes and Infrastructures using self drawn graphics

WEP was intended to provide comparable confidentiality to a traditional wired network (in particular it does not protect users of the network from each other), hence the name. Several serious weaknesses were identified by cryptanalysts — any WEP key can be cracked with readily available software in two minutes or less — and WEP was superseded by Wi-Fi Protected Access (WPA) in 2003, and then by the full IEEE 802.11i standard (also known as WPA2) in 2004. Despite the weaknesses, WEP provides a level of security that can deter casual snooping
