Channels -> Resellers

More and more of us are working remotely, for at least some of the time, enabled by an increasingly diverse range of mobile devices. For businesses this has many benefits whether it is making field based employees more responsive, improving workflow or enabling flexible working practices. But many studies show that the biggest perceived down side is security; for resellers this is an opportunity.
Remote devices themselves, be they smartphones, netbooks, tablets or laptops, provide only small margins for resellers, as do the network connectivity services that link them to back office applications. But mobile device management (MDM), software and services to manage and secure these growing fleets of devices, are more attractive.
Controlling what employees can get up to and ensuring that their use of IT is safe is far easier when they are constrained behind a firewall than when they are ‘at large’ with mobile devices. There are three basic problems to solve: protecting the device from malware, protecting the data generated and stored on the device and securing and authenticating the connection.
With the larger form factor devices (laptop, netbooks and some tablets – mobile PCs from hereon) it is possible to protect the device and the user by forcing access back via the corporate network. They are then subject to internal security controls. There are three basic ways of doing this:
Securing the use of smartphones has thrown up some new challenges and, as yet, it is not really possible to take a unified approach to managing all mobile devices. For a start it is harder to force smartphone users back on to the corporate network, due to the convenience of making direct internet connections via mobile network operators (MNO), second VDI is hard to adapt to their smaller screens, third there are different device based security products for the different types of devices and finally, the range of operating systems for smartphones is much more diverse.
There is one measure that can be taken centrally to protect all remote users; email filtering. Most organisations today will have this in place to catch spam and email-born malware and also to check what is being sent via corporate email. However, the target of many malware writers and an increasing source of data leaks is web traffic. It is possible to use proxies to force web access for mobile PC users via a central web traffic filter, but, for the reasons outlined above, this is less easy to enforce for smartphone users.
So, as smartphones increasingly become target for data theft and they are, by their very nature, easier to lose, it is necessary to make sure the device itself is secure. This also applies to any mobile PC for which internet access is allowed independent of the corporate network and, unless device based security blocks the use of low cost of 3G dongles, this is almost inevitable.
A few years ago, given the range of mobile operating systems, it seemed obvious to select a corporate standard smartphone and impose it. But the increasing overlap between work and personal lives means most employees prefer to use the device of their choice. This consumerisation of IT may look like a headache for IT managers, but it has one big advantage; if the device an employee uses for work is also their favourite toy – they will take more care of it – step one to mobile security – user love of their device!
But that is not enough; there are a number of other steps that need to be taken:
Ensuring all this protection is in place and remains so, that device software and security is up to date, and that action can be taken when a problem arises requires MDM tools. Such tools can also enable the auditing of device ownership and use, for example logging phone calls made, SMS content and photos.
For many businesses, especially mid-market and smaller ones, these will be new and unprecedented challenges. The number of threats and the range of options for mitigating them will seem daunting and the in-house skills will not be available. Resellers that provide tools and services for managing mobile device security and safe remote IT access will be relieving their customers of a headache and enabling their businesses for the future.
