PDA Security, the Next Big Hurdle for IT? 108

Jack writes "ITO published an article on a new secure PDA requested by the NSA. 'General Dynamics inked an $18 million contract with the secretive National Security Agency to design and develop a secure mobile personal assistant for defense workers. The PDA will integrate all types of communications including voice, data and web.'" In related news palmtops writes "Insecure Magazine has a great and in-depth article written by Seth Fogie, the VP of Airscanner.com, about Pocket PC security. His summary of PDA attacks states: 'These devices are easy to smuggle into a business and can be used to propagate an attack against network devices. Don't make the mistake of assuming is a PDA is a simple data keeper. As the cliche' goes... it is how you use it that matters.'"

      While such views are usually dismissed as conspiracy theories, I wouldn't laugh that fast. My dad (in the times when 286 were the hot new stuff) talked to an author of AV software, who admitted to releasing several viruses.
      This was in the times where most software of that kind was written by one-man companies. Now, in the days when AV is a major industry, are you going to bet that no virus authors are employeed by those who benefit the most from virii?
    • Even if a virus cannot attack the PDA directly, it can sit quietly in an email attachment on the device until the device gets synced to a pc, where it can affect the pc. This is where AV software can be useful now - ensuring the data on the device is clean before syncing it to a pc. Before long there WILL be plenty of malware designed to directly attack PDAs but with the wide variety of PDA platform/versions out there it will be difficult to target a sufficiently large set of users to accomplish whatever go

      I was happy when the pager business finally died. That reduced the number of gizmos that I was carrying around on a daily basis from 4 to 3; the cellphone features became advanced (and cheap) enough to obsolete the pager completely. At one time, I thought that I would probably snarf up the PDA/phone combo, but I haven't yet found one that I really want to buy -- the price/performance just isn't there yet. When the PDA/cellphone combination gets cheap enough (and full-featured enough), then I envision reducing my current gizmo count to 2.

      As for the laptop, it looks like that will be around for a while. At this point, the PDA just doesn't have the display or input capability to make it the all-in-one personal computing tool. In order for a PDA-sized device to displace the laptop, the I/O needs to get way more advanced, something on the order of a combination ocular/cochlear implant and voice (or better yet, thought ) recognition.

Blackberry servers allow admins to erase lost devices remotely, but I tend to think that "erase" is similar to a MS DOS format - i.e, barely touch the actual filesystem. To scrub a PDA's flash disk with numerous overwrites of random data would seem to be a good trick. Similarly, having a PDA render its flash permanently unreadable would also be a good trick, given the battery constraints.

    PDAs (and mobile "phones") seem perfect candidates for biometrics. They are easily taken from their owner's physical control. Their UI HW is so limited that passwords are a hassle. They're actually the main storage for many people's "memos", so remembering their password is a catch-22. They have the most personal info of any device, often just a tap away from indicating personal liabilities. They're just a year or two from acting as a universal digital wallet, probably wireless - almost certainly with dynamic IP#s. They'll usually be connecting through a brief relationship with an otherwise unknown LAN segment, like a public WiFi hotspot. And people will just completely trust them, especially because their userbase is among the least tech sophisticated.

    But also, most importantly, because they're so extremely valuable as security devices. People can trust their own phone, if really secured. They can carry it anywhere Especially once phones are <$20 each, they can have several secured phones left around their car, their office, other locations they frequent. A reliable biometric access device, like a thumbprint scanner, makes the "phone" an extension of the person's identity. Appropriate, when it stores both all their personal data, and their contacts with other people - as well as executing access to them. Securing one's phone can make access to the rest of the virtual world secure, at just the persistent device closest to us. If that little gizmo is really going to become our "universal remote" to all worlds both real and virtual, it needs to recognize us exclusively, and vice versa, to represent us there.
