Im Test: Colasoft Capsa 7 Professional [28.07.2014]

Netzwerkprobleme bereiten Administratoren immer wieder Kopfschmerzen. Denn sie sind oft schwer zu lokalisieren sowie nachzuvollziehen. Ein umfassendes Werkzeug zur Netzwerkanalyse möchte Colasoft mit Capsa Professional anbieten. Es verspricht eine einfache Bedienung sowie eine gute visuelle Darstellung, da ein Allround-Administrator in der Regel keine Zeit für eine umfangreiche Einarbeitung in eher gelegentlich genutzte Tools hat. IT-Administrator war vom Funktionsumfang überrascht. [mehr]

Zutrittskontrollverfahren im Vergleich [30.05.2014]

Ein Rechenzentrum stellt in der Regel für das Unternehmen eine wichtige und zentrale Funktionseinheit mit besonderen Schutzanforderungen dar. Aber auch das Gebäude, die Büros und sonstige zur Einrichtungen gehörende Gebäudeteile sollten vor unbefugtem Zutritt geschützt werden. Dieser Beitrag vergleicht die verschiedenen Zutrittskontrollverfahren. [mehr]
