Veracode Marketing recently polled a list of mobile security experts, asking them “What can employees do to minimize risk when bringing their own devices to work?” We’re pleased to present the responses from a wide array of security experts including David Schwartzberg from Sophos, Kevin Flynn from Fortinet and Veracode's own, Chris Wysopal. While all our experts have their unique perspectives, some common themes arose including changing employees' view of security. We want to thank all our respondents for participating and we welcome your thoughts too – use our comment area and tell us, “What can employees do to minimize risk when bringing their own devices to work?”
Even with the move to BYOD, information security is still a core IT responsibility. In other words, regardless of who owns the device, IT and Info Sec are still responsible for protecting the data on that device. Fortunately we have a growing arsenal of tools to help with that from the mobile device management companies like Sybase, MobileIron, Airwatch, Good Technologies, and the like.
While those solutions give IT the ability to enforce security policies like requiring strong passwords and file encryption, users are always the weak link in the security chain. Mobile devices are all about convenience, and unfortunately, security introduces some degree of inconvenience. It's long been known that if we make security too inconvenient, users will resort to the most insecure solutions to avoid it.
The two keys to success are management support and good communications with users. C-level execs are often the worst security offenders, but if you can plant the seed that we now have hundreds or thousands of potential security exposures traveling around in people's pockets or purses, hopefully you can get them to pay attention. Clearly, that's a lot easier to accomplish in regulated industries like health care and finance, but every company has information it needs to keep secure.
Security awareness must be part of employee orientation, and we need to explain why even seemingly innocuous information like a salesperson's calendar could hold a treasure trove of useful information for a competitor. People are far more willing to cooperate if we tell them why it's important.
However, this can't simply be a one-shot deal. Security requires an ongoing program of security awareness to create a "culture of security". I know of one organization that puts tent cards with little security "tips" on the tables in the cafeteria and changes them once a week. To build that ongoing awareness, you have to think like an "advertiser" and what you're "selling" is a secure organization.
BYOD is here to stay (at least in the near term), so IT and Info Sec specialists need to think creatively to truly protect all that sensitive information that's traveling around on smartphones and tablets. We're dealing with a whole different type of "perimeter" now, so we need to focus on protecting "data" rather than protecting "devices".
This BYOD movement reminds me of when I was in high school. There was a sign in the study hall which read, "Success is 13% Aptitude and 87% Attitude." I don't know where they got that ratio from, but in this context, the exact percentages don’t matter. The point is that with a little bit of smarts and a whole lot more positive thinking, you'll wind up where you need to be.
Most employees on a network don’t have the security aptitude to make the right choices when it comes to risk minimization with their own devices. They tend to choose first what’s free, then software with the most Consumerization of IT features and then whatever’s available on the sales rack at their local tech store. Generally speaking, their attitude is that risk minimization is the responsibility of the experts at their company. They will do the minimum required to prevent risk and protect data. Security gets in their way. Not a very good attitude.
Employees need to work with their security departments to get better educated on their organizations’ best practices for protection. Protection isn’t fool proof, so they also need to know who to call and how quickly to react when an incident occurs. Employees need to change their mindset to embrace that bringing your device to work also means that you need to take ownership of minimizing risk and protecting data.
Company leadership are generally early adopters of new technology that is brought to work. While that’s great for being productive (if they work), those devices are also higher risk. They are most targeted 1) for their street value and 2) because corporate executives tend to have the most interesting information stored on their devices. If you are a member of your company’s leadership, you need to comply with company BYOD protection rules just as much as your subordinates need to. No exceptions.
Some additional tips on how employees can protect themselves when they bring their own devices to work.
Devices aren’t the main problem in a BYOD strategy: employees are. That’s why BYOD is not just a technical issue that can be left to an organization’s IT department. It needs a holistic approach that includes HR, data security and legal stakeholders. Sensible organizations adopting a BYOD strategy will have put in place a strategy that includes policies and guidelines, as well as technical constraints and parameters. The main thing that employees can do to minimize risk, therefore, is simply to comply with the policy approaches that their employers have – presumably for carefully thought-through reasons – put in place. If an organization concludes that, for compliance and liability reasons, it wants to use a particular file sharing platform instead of, say, Dropbox, employees should comply with that restriction instead of simply applying their own workaround and using Dropbox because their own clients use it, it’s more convenient and they think that it’s great.
It doesn't help that many of the “approved” platforms to enable BYOD are less sexy and functionally flexible than “unapproved” ones – which encourages employees to go off-piste and use their own workarounds. So I think that the best thing an employee can do to minimize BYOD risk is to comply with whatever policies and technical parameters are in place and not take a BYOD policy as a licensed free-for-all. Pay attention to the forms, declaration or pop-up screens that warn of the scope of your organization’s BYOD program and how security applies to it.
And one final thing: just be sensible. There was a reported case over here in the UK just last month of a someone who showed his young son how online spread betting worked and then left his laptop around unsecured. You’d be surprised how short a time it takes for a 5 year old to run up £50,000 in losses! You can’t blame the device or the policy if someone willfully or recklessly ignores the rules.
The first thing employers need to do is to create and maintain an "authorized BYOD device list". Employees wishing to bring new devices should submit a request for addition to this list. It should also be ensured that a remote wipe facility exists and is enabled, especially if company confidential information will be stored on the device.
Here are a few other things we encourage customers and our employees to practice:

Relying on employees to deal with security issues is like putting teenagers in driver's ed classes. It may help make them better drivers but it doesn't make them good drivers.
Nonetheless, just like teenagers can use driving tips, employees can use tips on how to minimize risks when bringing their personal devices to work.
First off, no jailbreaking! There's just too much that can go wrong when someone tries to open up the OS on their smartphone.
Second, the age-old recommendation to back up data applies to tablets and smartphones as well. The complicating factor is that you might not want them to back up their business data via their personal back up methods. Backing up their work emails and documents should be done on the business network and nowhere else.
As for applications, it's better to be safe than sorry. Android by default blocks users from installing apps that aren't in the Android Market. And, while there are other legitimate places to get Android apps (such as the Amazon Appstore), do you really want users to enable "Unknown Sources?" This is less of an issue for iOS devices, but nonetheless, remind users to be careful what they download. Another hint is for them to check the settings of EVERY application they download. Apps have a funny way of sending private information to the net.
Now, with all these things said, good security really begins on the network. The move to personal devices at the office is a continuation of a trend that started back in the 1980's when accountants began buying Personal Computers to run Lotus 1-2-3. Since that time, organizations have turned to network security to protect themselves. Since the network handles all the traffic (no matter what the user is doing while at work), the network is the best place to secure that traffic, log it and report on it.
An employee bringing their own devices to work is not a new concept; the problem in today’s world is that they want to connect the devices to corporate networks. Some may want to access wireless networks so that they can bypass web filters, other want to use their device to access business applications and data. Whatever reasons the employee gives for bringing a device to work they should follow these basic tips to minimize the risk they present:
Employees need training before using their own devices. Risk profiles change dramatically as soon as any company allows any form of external device connectivity - whether via 3G, 4G or WiFi. Employees need to understand and share the risk with their employers and this needs careful planning.
In its simplest form, companies should consider using dedicated 'sandboxed' applications to allow access to information under the control of proper authentication, encryption, and access control frameworks. Ideally, these dedicated applications should automatically enforce security and privacy controls, while providing management tools to enable or disable services remotely.
Employees should always lock their devices - and employ a second, different passcode to work-related applications. In this way, the device and its data have a basic level of protection.
Also, every employee should read and understand the company policy on device usage - mobile devices deserve their own category in all policies - and these require regular review. Technology changes rapidly in the "bring your own device" (BYOD) environment, and policies need to reflect changes in technology, platforms and services. Employees, therefore, need to keep themselves up to date with new policies and raise any concerns with appropriately qualified technical managers.
Employees also need to consider questions such as legal use and liability for use. After all, an employer has permitted an employee to use a personal device. The company has no right of access to personal possessions, therefore, can the employer demand a full audit of a device and all its data? If so, what controls does the company have in place to protect any personal information from abuse? Another reason for implementing sandboxed dedicated applications - the company can then control its own sandbox, without needing to inspect the device as a whole. Remote wipe becomes a particular risk in a non-sandboxed environment - the company may need to wipe its data, but leave the employee's data and applications intact.
Mobile devices also require regular software updates to remain current. Employees need to check with employers prior to updating devices with the latest operating systems or services. Upgrades may break legacy services and applications then require updates as appropriate. Employees need to consider the liability issues of introducing a problem by simply upgrading a device in line with the manufacturer's recommendations.
Fundamentally, device owners need to assume that others will have access to their devices. Or that work will sometimes come in at a less than opportune moment (in the middle of a party, or during the night) or while the employee travels. In these circumstances, profiles and policies should reflect working hour directives, and consider the implications of an employee having 24 hour communication with the company. In many countries, directors have a legal obligation to protect the well being of their employees and should promote or enforce sensible working hour directives.
Employees may also want to consider what happens when things go wrong: what happens if broadband or mobile data services fail? Who pays for excessive data consumption or international roaming charges? How do you back up, restore, lock or remove data from devices - and prevent its loss? Does the company provide adequate controls over encryption policies (so that an employee could move between countries where encryption laws differ, without risk of imprisonment, for example)? Who insures what - and who pays for the insurance (does your domestic insurance cover your equipment for business use, for example)?
Proper policies and training resolve many of these issues. This topic really covers managing risk - in a shared environment. Employers and employees need to take responsibility for their own tools and provide adequate assurances (through regular audits) that the chosen device, any applications, data, and the associated management processes all operate correctly.
I’ve already accepted the fact that Bring-Your-Own-Device (BYOD) is a business trend that’s here to stay. According to "BYOD or Bust: Survey Results Report" by Software Advice, Inc. I recently read, just 23 percent of enterprise employees use company-sanctioned mobile devices only - meaning 77 percent of employees are using their own devices in some capacity to do their job. As the Chief Information Security Officer at Veracode I have experienced this trend firsthand and if it hasn’t hit you yet, the BYOD tidal wave is coming your way!
Formulating a BYOD policy is only one side of the equation – employee education is the other. Most business users simply aren’t aware of the security threats facing them when they use their favorite mobile device at work. We need to increase that threat awareness level and ultimately convert employees into willing participants in a secure mobile computing or BYOD program.
Here are ten tips to help device users protect personal information as well as their company’s data, IP and brand when they use their mobile devices at work.
