WSJ summarizes the issues in How BYOD Became the Law of the Land:
The most challenging adjustment—and one that still has the longest way to go—is the need for better systems to authenticate network users, essentially all of whom now access corporate systems with mobile devices. This is an area of strength for RIM, known for the resilience of its security network. The IT infrastructure to support BYOD "has grown up quickly, with the exception of identity management," Mr. Dulaney said.
CIOs also have shifted the onus of responsibility for the devices and the data they process to the employees themselves. CIOs created new policies spelling out how companies and employees would treat mobile devices and data, and by addressing related questions of liability and insurance. In some cases, companies insist on the right to wipe a device clean of all information, including personal files and data.
The initial response from IT security to mobile was MDM, this is fine but nowhere near sufficient. The device level of granularity is not enough to deploy and enforce security policy in the same way that "Laptop user" is not good enough. We need user identity, app identity, and data encryption. And we cannot always assume that the server will be in play. Further, MDM is only applicable for enterprise and does not help with the myriad of customer facing, external mobile apps that are being deployed every day.
Then there is the server side, Travis Spencer did a round up of some of the core identity issues at play here. From there decisions need to be made on key management, hardening Mobile web services, and implementing Gateways. So there is a lot to do and not much time to lose, because if you look, the risk of your mobile apps - what they are transacting - is pretty high. Another little wrinkle is that many initial mobile app projects are outsourced, so there tends to be this black box - well Company X is responsible. But the security team should really be more actively engaged and in a proactive way to make sure there is a Mobile specific security policy that is backed by guidance, architecture, patterns, and testing that the end product gets the job done. But before we get to all of that, we must NYEAABTODADWI .
