ARP-GUARD provides a secure basis for consistent e-health processes at the DERNBACHER GROUP

Around 6300 employees work for the DERNBACHER GROUP KATHARINA KASPAR at 130 locations. These include six hospitals and six outpatient clinics. Accordingly, the Group has a particularly high set of requirements when it comes to IT infrastructure. ARP-GUARD has enabled the Group to transform a complex system into a carefully designed concept.
 

An innovative concept to secure critical infrastructure
IT and medical technology need to enable providers to deliver cost-effective and needs-oriented medical services. With this in mind, it was time for the DERNBACHER GROUP to update its IT infrastructure. The variety of different locations, device groups, endpoint devices and users had led to the emergence of a highly complex system within the Group, complete with its own security risks. In order to secure the critical infrastructure, a carefully designed concept needed to be implemented at the hospitals. As Head of the Group's IT Division at the DERNBACHER GROUP, Achim Pfeiffer worked to find a solution that would assist him in assigning known device groups, and uniquely identify and offer protection against unauthorized devices, among other tasks. The Group ultimately opted to invest in the ARP-GUARD NAC solution from ISL Internet Sicherheitslösungen GmbH.


ARP-GUARD bringt deutliche Vorteile
ARP-GUARD bietet die Möglichkeit, Geräte eindeutig zu identifizieren und anhand definierter Regeln in Gerätegruppen und zugehörige VLANs zu sortieren. Fremde Geräte werden somit isoliert und das Eindringen Unbefugter in das Netzwerk verhindert. Mit dem Network Access Control System konnte die DERNBACHER GRUPPE ihren standortübergreifenden Netzbetrieb weitestgehend automatisieren, eine transparente Übersicht über sämtliche Netzwerke schaffen und eine schnelle Lokalisierung von Endgeräten im gesamten Kliniknetz ermöglichen.
Daneben ist eine einfache Integration von VoIP-Geräten und WLAN Access Points möglich und Patienten sowie Mitarbeiter können ihre mobilen Endgeräte sicher und bequem in den Kliniken der Gruppe nutzen.
Der erfahrene ISL Premium Partner GORDON begleitete die DERNBACHER GRUPPE bei der erfolgreichen Umsetzung ihres NAC-Projekts. Mit ARP-GUARD verfügt die Unternehmensgruppe nun über ein BSI-gerechtes Sicherheitsniveau in ihrem Kliniknetzwerk.


ARP-GUARD offers a whole host of major advantages
ARP-GUARD enables administrators to uniquely identify devices and sort them into device groups and associated VLANs according to defined rules. This ensures that external devices are isolated and safeguards networks against access by unauthorized devices. The network access control system enabled the DERNBACHER GROUP to largely automate network operations across locations, generate a transparent overview over all networks and quickly locate endpoint devices over the entire hospital network. In addition, NAC also facilitated the simple integration of VoIP devices and WiFi access points, and permitted patients and employees to securely and conveniently use their mobile devices at the Group's hospitals. Experienced ISL premium partner GORDION supervised the successful implementation of the DERNBACHER GROUP's NAC project. ARP-GUARD has ensured that the Group remains compliant with the security level required by the Federal Office for Information Safety (BSI) across its hospital network.
