Enabling High-Performance for Apple iPads in the Enterprise Aruba White Paper
Aruba’s stateful rewall enforces security and access policies. The rewall tracks upper-layer ows and ensures that
unauthorized trafc cannot bypass access control. Policy violations can be acted upon to deny trafc, quarantine
devices or remove devices from the network via a blacklist. Aruba’s rewall is certied by ICSA Labs, the industry-
recognized benchmark for rewalls.
Aruba’s integrated wireless intrusion detection and prevention (WIDS) system reduces deployment and management
costs by using access points to simultaneously serve clients and contain wireless threats. With Aruba, there’s no
need for a costly overlay IDS with dedicated sensors. Automatic threat mitigation protects the network from
unauthorized clients and ad hoc devices even as they roam. The IT organization can customize the security policies
by criteria such as location, device or conguration. Integrated wireless security within Aruba WLAN ensures
increased channel availability hence increased network performance for wireless devices, including Apple iPad.
Table 2 shows the results of Aruba’s authentication and encryption testing for iPads.
Ensuring Seamless Mobility for iPad in the Enterprise
iPad users are free to move about the Aruba wireless network. Aruba supports fast, seamless roaming across both a
single IP domain as well as across multiple IP domains. Clients can move from AP to AP in less than 50 milliseconds
while keeping the same IP address. Fast roaming maintains a continuous application connection, which is critical for
latency-sensitive applications such as voice and video.
We tested iPad roaming on the production network at Aruba corporate headquarters – a typical corporate ofce with
cubicles, walls, furniture and people. As in any real-world conguration, iPads shared the air and network with other
wireless clients, including as laptops, wireless VoIP phones and security cameras.
