This time around, the experts offer insights on this question:

Q: “Dear Experts, what are the key things I need to keep in mind when I write my company’s mobile security policy?” — MK

John Davis starts us off with:

I would say the most important thing is to actually write your own policy; don’t just copy a generic mobile security policy from the Internet and adopt it as your own. For a mobile security policy to be effective, it needs to be tailored to meet your organizations particular information security requirements and also needs to reflect the reality of mobile device use at your organization. It won’t do you much good to forbid using mobile devices for business purposes if you have no mechanisms in place to prevent or detect such uses. Effective information security policy, like effective statute law, is both practical and enforceable.

Adam Hostetler added:

Keep in mind what kind of current security policies you have, and try to apply that to the mobile sphere. Users need to understand that they are connecting an additional computer to the network, and not just a “phone”. Keep in mind also what kind of deployment you are using. Is it bring your own device, or is it company provided? There will be different policies and procedures for each method and possible user backlash depending on how you are doing this.

As always, thanks to the experts for weighing in, and to the readers for the questions. Keep them coming!

How Cloud Computing Will Leak Into Your Enterprise

“Consumer use of the cloud”; in a phrase, is how the cloud will leak into your enterprise, whether you like it or not. Already, IT is struggling with how to manage the consumer use of devices and services in the enterprise. Skype/VoIP and WIFI were the warning shots, but the BlackBerry, iPhone, iPad and other consumer devices are the death nail for centralized IT (and IS) control.

Consumer electronics, backed by a wide array of free or low cost cloud services, are a new frontier for your organization. Services like MobileMe, DropBox, various file sharing tools and remote access services like GoToMyPC, et al. have arrived. Likely, they are in use in your environment today. Consumers use and leverage these services as a part of their increasingly de-centralized online life. Even with sites like Twitter and FaceBook growing in capability and attention, consumers grow their use, both personally and professionally of services “in the cloud”. Make no mistake, despite your controls at the corporate firewalls, consumers are using their mobile and pocket devices and a variety of these services. Unless you are searching them at the door and blocking cell phone use in your business, they are there.

This might not be “the cloud” that your server admins are worrying about. It might not represent all of the off-site system, database and other hosting tools they are focused on right now, but make no mistake, this consumer version of the cloud has all, if not more, of the same issues and concerns. Questions about your data is managed, secured and maintained all abound.

Given the “gadget posture” of most organizations and their user communities, this is not likely to be something that technical controls can adequately respond to. The consumer cloud services are too dynamic and widespread for black listing approaches to contain them. Plus, they obviously lack centralized choke points like in the old days of “network perimeter security”. The new solution, however, is familiar. Organizations must embrace policies and processes to cover these technologies and their issues. They also have to embrace education and awareness training around these topics with their user base. Those who think that denial and black listing can solve this problem are gravely mistaken. The backdoor cloud consumer movement into your organization is already present, strong and embedded. Teaching users to be focused on safe use of these services will hopefully reduce your risk, and theirs.
