But what about the security of my information?
All right, its no secret Ive become an ardent Apple supportersome might even say fanboy. But lets get past that and take a real look at just how secure this iPhone gizmo is.
My reasons for going through all the hassle associated with switching mobile phone carriers are varied, and Im completely happy with the choice I made.
But Im also not so blinded by this game-changing device that I was willing to sacrifice security to use. During the transition, I was very aware of security issues and I always looked into what security choices I could make.
Lets explore some of those a bit here. But first, lets look at some of the bigger security exposures from using the iPhone.
From a stand-alone sense, many of the security issues are similar to what Blackberry owners and administrators face daily. Youre probably concerned with locking down the device itself, along with its data, in case you lose it or the phone gets physically stolen, for example.
That is, youre concerned about the sensitive data that sits at rest on your device. Thats a fair concern.
Next, youre probably concerned about your sensitive data in transit between the device and the server-side applications youre using. Again, a very fair concern. You certainly dont want to fall prey to what I call a coffee shop attack where an attacker with a Wi-Fi network sniffer captures your sensitive data, such as login credentials, documents, emails, etc.
For much mobile business dataemail, calendars, contacts, and suchthere are three modes of connections that are common for iPhones.
You can tether the device to an enterprise email server, such as a Microsoft Exchange server. You can use Apples own MobileMe service to deliver and synchronize the data. Or, you can simply run the iPhone as a stand-alone mobile device, where you synchronize your data with a regular Windows or Mac computer via a USB cable.
Most enterprise users will use a Virtual Private Network (VPN) to connect their iPhones to their corporate networks, and from there to their companys Exchange server. That combination goes a long way to protecting sensitive company data in transit between the iPhone and the companys infrastructure. It pretty much makes you immune to the coffee shop attack, for example, since all the data in transit is likely to be encrypted via the IPsec-compatible VPN.
Similarly, from what I can gather, connections to MobileMe are encrypted to protect the sensitive data in transit. By default, for example, incoming emails are encrypted using SSL between MobileMes email servers and the iPhone.
But if youre not using Exchange or MobileMe, email is a little different.
Say, for example, youre using your standard ISP for email via IMAP or POP3, and SMTP for outgoing messages. There are definitely some things you need to consider for securing those connections so your sensitive data cant easily be captured while its in transit.
Many ISPs, for example, support SSL-encrypted email connections via IMAPS, POP3S, and SMTPS. If your ISP supports these, use them!
Sure, Internet email isnt private by even the wildest stretch of imagination. But with IMAP, POP3, and authenticated SMTP, its quite likely that your login credentials are being sent to the remote server during each transaction. Although there are plenty of other options for protecting those credentials from disclosure in transit, SSL is quick and simple.
Theres good news on this front, though. If your Mac email is already set up with secure email settings like Ive described, your iPhone will automatically get those same settings the first time you set it up via an iTunes synchronization.
Nonetheless, spend the time to step through the iPhones email settings and verify this is the case. Its no guarantee, but it will provide pretty good protection against that coffee shop attack.
One of the ways around the issues of security and control that make some businesses wary of cloud computing is to build a private cloud -- one that remains within the corporate firewall and is wholly controlled internally. Private clouds also increase the agility of IT an organization's IT infrastructure and make it easier to roll out new technology projects.
