Its quite some time after the GoogleIO. Have been busy digesting some info and thinking a lot. Just a day before IO, I wrote some of my thoughts on Enterprise mobility. Today, I'll try and visit certain aspects in detail as well as try to list what Android has to offer as of now.
Now, from current trends in market and from my understanding till date, I see the current enterprise mobility having 3 components as follows :
1. Device Management
2. Security
3. Application management
Enterprises looking for a complete mobility solution are mostly looking at these three areas. I'll try to briefly touch on each of these and discuss what Android has to offer (and not offer) to enterprise mobility. [For clear separation, I have marked Android Specific details in BLUE : I know Green (#A4C639) would have been appropriate, but I didn't think it was good for reading :)]
1. Device Management : Device management (DM) mainly deals with being able to remotely alter certain aspects of the devices. Again, I see DM being split into the following.
![](https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgzKnu9zK8GShNFNBTLDrAmwKgxw97gET-Uq0d_ccO5tzpkPLMS7pJjHmJCYIAhb1KpMgas6Yl8nDIgwDzQyhYX5FanSOBhXK4jfkLbXEUes_e5koZxzqCn_chsIGpajF5QsU8tLqGQOe0/s320/Screen+shot+2011-06-09+at+11.25.57+PM.png)
i. Provisioning deals with mass deployment of various settings on large number of handsets. For instance, provisioning the devices with corporate WiFi information, VPN access parameters and configuration of email settings etc... For the IT department, being able to provision these settings is beneficial since it helps them carry out the tedious task as well as reduces chances of human error and avoid complex email instructions.
Blackberry and iOS have most of the DM functions baked into the platform. This means, one can configure a DM server (may require manual steps). Once configured, the DM server can send commands to the device which will be understood by the device platform and reacted accordingly.
Android, however, requires an on-device management agent (aka Device administrator) which should implement the Device Admin APIs (Android 2.2 onwards) in order to perform any of the DM functions. Furthermore, Android doesn't support provisioning out of the box. Rather of all the top IT demands (WiFi, VPN, Exchange etc...), only WiFi can be configured programmatically by the on-device agent.
ii. Device Control deals with being able to remotely take certain actions on the device that may affect the end user. E.g. device lock, unlock, wipe, set/reset password.
With the device admin software installed, Android can do these basic device control functions like device wipe, lock/unlock and set/reset password.
There is however one way to achieve device control functions without having to install any device admin. The trick here is that most Android devices ship with a Email application which can be configured with Exchange information. By default Exchange uses the ActiveSync protocol for syncing mails. Of lately (I guess Android 2.2 onwards), I have seen that while configuring Exchange, the platform shows the standard Device Management screen asking for adding the Exchange as a device admin. If you do this, then by configuring the Email, you can execute device control commands like lock/unlock, set/reset password, wipe etc... To check this go to Settings -> Location and Security -> Select Device administrators. You should be able to see Email application being listed if you have configured Exchange (ActiveSync ).
2. Security : By far, this is THE feature enterprises cannot live without. When enterprises allow data to be accessed remotely, its security is of prime importance. There are 3 components related to security that I visualize as follows:
![](https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjhJqbWSFUdwAxbMK2PiKk-TLwthu8OSMxk3E7tbT18dRMz2oh1LhHfZ1iEnItZ1-Jz4zL2Hl9SNaCcLw_4dvDAsmIwRM_rc5Q_NF97Btp3ljURfS3dgDT4rILUV8kt8svyJksxIJLPSdU/s320/Screen+shot+2011-06-09+at+11.26.30+PM.png)
i. Encryption : Any data that is stored by any application as well as any data that is communicated to and from the device, needs to be encrypted.
Android apps can use SSL tunnels through with data can be transported. However, the data stored on the device (phone memory and SD) is up to the applications. Prior to honeycomb (Android 3.0) there is no support for turning on encryption on the device. Even with Honeycomb, a device administrator application can request for the encryption process to begin, and it will start the encryption ONLY IF it is supported by the device on which the agent is running. Things are still pretty unclear about the way encryption is supported (hardware vs software etc...). One of my previous posts raises these issues. I'll update both the blog posts once enough information is available.
ii. Device Policies : I have purposefully included policies again under Security. I think this link is important to note. This is just to remind that policies are restrictive settings enforced in order to avoid security compromise.
iii. Compliance : Now, we have policies in place. And as I said these need to be enforced on the device. However, it may happen that the user knowingly or unknowingly changes some setting that violates certain policy (that cannot be technically enforced on the device - technology limitation). This may put corporate data at risk. It is important for the IT to determine such instances. This leads to constantly monitoring the device and making sure that it is "in compliance" with the policies.
Usually, compliance checking may be done on the server that monitors the device. This can be achieved by querying the device for certain parameters periodically and then running the compliance rules against the values received. These rules usually test whether the device adheres to all the policies, if not then the resulting actions could be anything from blocking corporate access for that device to wiping the device. This totally depends on the IT policies for the enterprise.
The device admin app can play the role of reporting parameter values to the DM server. To monitor Android for certain metrics, the server can implement the Google C2DM (cloud to device messaging discussed in this blog post) to send query messages to a device admin app which can reply back.
3. Application Management : One of the basic goals for enterprises is to mobilize the business. As a result, enterprises have started mobilizing many internal applications. So, as a part of enterprise mobility, the IT also has to manage the mobile apps. Application management (AM) can be again viewed as having the two main functions :
![](https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhsP1KkEuTIoWVmJ6m5fk-xsdFW3ZgPNe95MY7mceETjh0d3-OH0X3xMrQEv10gVJ2HJenUgK2BFJ4Tsj82w7VJDozk5w4yVs2fAbs3AKRmQL1z1vBs1n58CaofshWjclOXujq4VmmMOUQ/s320/Screen+shot+2011-06-09+at+11.26.45+PM.png)
i. Monitor/Debug apps : Since most of the applications may be internal apps, the development and testing phase becomes critical. Also, since these apps may directly affect employee productivity, debugging these apps during development and after deployment is crucial too. One of the tasks of AM is to help the development and debugging process easier. Once the app is in production, AM can help monitor the status of apps and surface any problems earlier. Monitoring of apps may also refer to getting an apps inventory and determining "blacklisted" apps from security point of view. This may tie back to compliance.
ii. Deploy / Remove apps : With many such applications there is a demand for Enterprise application catalog on which apps would be listed and shown/accessed depending on the role of the employee. Since these apps may contain critical corporate information, it is important for the IT to be able to control these apps remotely. Being able to install, remove these apps is one of the most popular demands from IT.
With Android, anyone can "sideload" an application. This means all the application (apk) files can be accessed via a webpage. However, there are few points to note. In order to install any application that is not listed in the Android Market (consumer app), one has to enable a setting called applications from an "Unknown Source". While doing so, the user gets a dreaded message that may scare him off. Also, it is worth noting that there is currently no official way to push the application on the device and install/uninstall it without the user intervention. If you already have your device admin agent on the device, then it can download the app binary and trigger the install process or trigger the uninstall process of an existing app which will redirect the user to the install/uninstall approval screen. There are some app markets (like AppBrian) which have (with limited capabilities) "managed" to remotely push and install applications on Android phones. However, there is no official way to do so.
So, here is a complete picture of how I see Enterprise mobility as of now:

To summarize, Android really doesn't have much to offer at this moment apart from few Device Admin APIs and Encryption (hardware dependent - 3.0 onwards). With the growing demand for Android and the changing trend of Employee liable devices, it certainly is a challenge for IT. The Google enterprise team unfortunately didn't seem to address most of these issues and didn't seem open to a lot of questions posed at the GoogleIO. The talk at GoogleIO can be found here : (http://www.google.com/events/io/2011/sessions/taking-android-to-work.html) I hope they have some plan for the Enterprise mobility because the wave has just begun.

iii. Device Policies : Policies allow enterprises to control certain settings of the device. This is different from provisioning in that policies can be considered as 'enforced' settings. While someone may change the provisioned settings, device policies are not "meant" to be changed. On Blackberry and to some extent the iOS, the platform restricts the user from changing any policies set by the IT administrator. These policies may include restrictions on the browser to disable javascript, avoid using the phone as USB storage device, disabling camera, etc...
Again, in the case of Android, you will need the on-device admin app to control (only) a subset of what the IT demands traditionally. Basic policies like enforcing a device password, password quality etc.. are supported out of the box with the Device admin APIs.
