January 12, 2006 Smartphones/PDA Update @ WestNet

Synchronization problems
Cradle / Bluetooth synchronization– Cable, IR, Bluetooth links unit to a computer– Effectively a backup tool for device– Old, clunky approach; what you need is…
Over-the-air synchronization– Must consider portable device, wireless carrier,
data plan & University backend systems– Good.com’s – “Goodlink” – Push Technology
$300 per device / Per year….Insurance
![Page 14: Smartphones Update Chad Burnham University of Denver WestNet Meeting January 12, 2006](https://reader036.vdocuments.us/reader036/viewer/2022062407/56649d545503460f94a31aad/html5/thumbnails/14.jpg)
January 12, 2006 Smartphones/PDA Update @ WestNet
14
Over-the-Air Synchronization
Stay current with mail and calendar All require IP accessible backend server
– MS-Exchange most common (ActiveSync included with 2003/2005)
– Symbian and Palm have licensed ActiveSync
Windows Mobile 2003/05 supports “push” synchronization via SMS messaging

January 12, 2006 Smartphones/PDA Update @ WestNet
15
Security Concerns
Web, email most popular applications– Consider history of web client vulnerabilities, email worms
and viruses
Physical security – what do you get when you find or steal one of these?
Transmission security / interference / sniff– Bluetooth 2.0 / 802.11X
Authentication – especially important Carrier security

University Data Environments
More mobile devices are emerging Faculty, Staff and Students desire to access
DU’s portal and overall electronics resources using these newer devices– “Can’t I just…?”
“Too many types of devices” places a significant strain on support staff

Smartphones / PDAs @ DU
Currently no site license @ DU for Smartphone/P.D.A. Anti-Virus packages
– “on your own”– Looking into it for Fall of 2006 (Symantec)
Smart phone or P.D.A. is lost/stolen– What is at risk?– What is the policy?– Do you have one?
As bandwidth increases and 802.11 is integrated, more apps will appear (BitTorrent for Windows Mobile?)
Cisco dropped official VPN Client support for their gear

No official policy on supported PDAs/Smartphone Privacy Policy – not in place Formed Informal internal UTS Group / Mailing list

DU is continuing to maintain a laptop requirement for students – not PDAs / Smartphones!

DU – University Tech Services
Researching sonicmobility.com: (Avocent)– Sonic Admin 4.1– MS-Server Admin Functions– Do not need or use RDP– Smartphone/PDA client much easier to read– Blackberry, Pocket PC and Palm OS Clients

MS Exchange Server Best?
Good for Administrative / Staff users– not so good for Students?
No commercial product supports OTA synch. using disparate calendar and email services
Exchange has clear market share for integrated calendar, email
Quick poll – who has standardized on Exchange for email & calendar?
