4 Rules of Thumb for Better Mobile Device Security

Security threats are everywhere, lurking in alley ways and around corners and even in your favorite coffee shop. Yet mobility is in demand, and people will use their smartphones and other mobile devices because it’s convenient, even if company policy suggests against it.

This is a big deal for IT and security professionals and CIOs, which is why it took a while for IT to recognize the need to address mobile device security rather than simply deny mobile device use. With data breaches, ransomware attacks, hacks and information leaks happening on an almost daily basis, businesses must find ways to protect their valuable applications and data from loss or misuse while at the same time enabling mobile device use.

The following 4 rules of thumb are not comprehensive but are four essential rules of thumb to help guide business owners in addressing mobility management and security within their organizations.

Rule 1: Make sure there are clear mobile device use policies and support them with ongoing administration and strict enforcement.

I can’t say enough about having good security and mobile device policies and keeping them modernized, relevant, and actually enforcing them. Too many businesses say they have a “security and use” policy in place, yet it is outdated and doesn’t reflect the actual tools or processes currently in use.  Even more frequently a business will develop a policy just to say it has one, but won’t actually train workers or enforce compliance.

Rule 2: Require and enforce strong passwords, manage access in real time, and force password changes with some frequency.

It is essential that all user access to applications or data be controlled at minimum by password-protected logins to the device and corporate resources coupled with periodic forced password changes. Users often prefer to not require passwords or other authentication for device access, but corporate policy should not only require them but also enforce their use.  Also, user access should be managed in real time, meaning that any aspect relating to access should be disabled or revoked immediately upon employee termination or reassignment. Too often these forgotten chores are relegated to after-the-fact IT administration, which allows users to access resources beyond their rightful boundaries.

Rule 3:  Do something to contain the applications and data on the device.

Whether the approach is with containers, cloud hosting, server-based computing or something else, it is really important to try to “contain” the applications and data accessed from the mobile device. Risk is created when users sync data directly to the device’s storage or install applications directly on the device to access corporate data. Password and other security measures prevent unauthorized access, but allowing applications, credentials or data to be stored directly on the mobile device allows those things to interact with other things on the device.  Containers, hosting and server-based computing models keep the applications and data within secured spaces, often not even storing essential items on the device but only accessing them via the device. This allows the business to provide users with the access and functionality they need to do their jobs, but also reduces the vulnerability of applications and information assets.

Rule 4: Keep device software up to date and download fewer apps.

Updating mobile device operating system versions and release levels is important to make sure the device has the most current security patches and threat protection.   Some mobile OSes even have capabilities which can help keep personal and work apps separated.  Limiting the number of apps users can download to their devices should also be considered. Users may randomly download and install applications to their devices with little regard for the quality or security of the app, and often accept terms of use without really reading them. Consumer apps from app stores may pose risks to data and the device, so IT should check regularly for problematic apps if the device is used to access the corporate network, applications or data.

Mobile and wireless are in demand

Just about every business has people who use their phones and tablets for some business use, and every one of those mobile devices and the apps running on them could open the door for a hacker, ransomware, data theft or compromise. While there are many benefits to be gained by enabling remote and mobile devices in the business workflow, unrestricted access only creates risk.

Keeping mobile devices secure for business use takes multiple approaches, as there is no single method or solution that works for every situation. Our 4 rules provide a basic foundation for business mobility management, offering a starting point for developing a more thorough and detailed plan.

Securing Business Data When Mobility is the Target

driving1-ANIMATIONToday’s workforce is a mobile workforce. Technology has enabled businesses to allow their employees to reach beyond the office walls, doing business and operating effectively from just about any location.  SaaS, online access to business data, and smart phone technologies have brought flexibility in working models previously only imagined by the workforce tethered to business locations and office computers. Yet this flexibility comes at a price if the business is to keep up with securing and protecting data assets as readily as it extends access to them.  The bad guys are well aware that mobile computing and remote access working models are growing in adoption with businesses, and are finding ways to take ever-greater advantage of the situation.

Teleworking, which is not quite the same thing as telecommuting, is on the rise and it doesn’t look to be a trend that will slow down any time soon. According to GlobalWorkplaceanalytics.com, “telework is defined as the substitution of technology for travel”.  Those who work sometimes from an office, but sometimes not, are teleworkers. Working at the office during the day and then taking work home at night makes you a teleworker. The primary tool of the teleworkforce is the smart phone – the mobile computer with built-in connectivity and enough processing power to handle many basic office workloads.

  • 50% of the US workforce holds a job that is compatible with at least partial telework and approximately 20-25% of the workforce teleworks at some frequency
  • 80% to 90% of the US workforce says they would like to telework at least part-time. Two to three days a week seems to be the sweet spot that allows for a balance of concentrative work (at home) and collaborative work (at the office).
  • Fortune 1000 companies around the globe are entirely revamping their space around the fact that employees are already mobile. Studies repeatedly show they are not at their desk 50-60% of the time.  http://globalworkplaceanalytics.com/telecommuting-statistics

The number of teleworking employees is on the rise, and so is the variety of devices used to facilitate mobile working.  Smartphones, tablets and phablets and, of course, laptop computers are used by mobile workers – often in addition to the company-supplied desktop in the office. The variety and number of computing devices per user is growing. Knowing this, businesses must take increasingly expansive steps to strengthen and secure remote access systems and business data, yet many organizations are just beginning to fully realize that the mobility they extend to their users is part of the reason for the increasing number of data breaches and attacks against business information systems.

Cybercriminals and their crafty programs are often able to steal important information or access a network by first infecting computers and devices used for telework.  Many of the devices available to the attackers are not company-owned, but are introduced to the system by contractors, vendors and employees (BYOD or bring-your-own-device users).

Even if the device isn’t a vehicle delivering a nasty payload into the network, data breaches may still occur when business information is stored on an improperly secured device. Most people who work with computers have some recognition of the potential for virus attacks and malware, but far fewer recognize the threat potential of attacks against mobile devices such as phones and tablets, and even fewer may implement meaningful protections on those devices.

“To prevent breaches when people are teleworking, organizations need to have stronger control over their sensitive data that can be accessed by, or stored on, telework devices,” said Murugiah Souppaya, a NIST computer scientist. [1]

Providing guidance and information to the public on such topics, NIST (National Institute of Standards and Technology) is revising its publications on telework to cover growing use of BYOD and how contractor and vendor devices are increasingly used to access company information resources.  Two new publications – one for organizations and one for users – are now available for review and comment.  You can find them here.

“As one of the major research components of the National Institute of Standards and Technology, the Information Technology Laboratory (ITL) has the broad mission to promote U.S. innovation and industrial competitiveness by advancing measurement science, standards, and technology through research and development in information technology, mathematics, and statistics.”  [NIST Information Technology Laboratory Mission]

The rising number of threats, attacks and breaches caused by compromised devices used for teleworking is nothing to take lightly, and protecting against them shouldn’t be approached as a merely perfunctory obligation. Organizations must create and consistently update policies and requirements relating to protecting information accessible by remote workers if they intend to reduce business risk and provide assurances to stakeholders and customers that the information is adequately guarded.  But it doesn’t stop with the policy; businesses must also make an effort to properly educate their users (employees, contractors, vendors, etc.) on those policies, ensuring that all parties involved understand the responsibilities and requirements and strictly adhere to them.

Mobile Device Security is a Moving Target

Mobile Device Security is a Moving Target

mobile-devicesAs businesses mobilize their workforces and processes the volume and variety of sensitive data passing through and sitting on mobile devices increases dramatically.  Even though the business owner or IT manager may recognize the importance of mobile data and device security, doing something useful about it is altogether another issue.  New considerations enter into the picture frequently, turning mobile security into a moving target. Protecting the business – the organization, its employees and its customers – requires adopting mobile security strategies that cover a broad range of issues.

First of all, is there any means of monitoring the activities of the connected or mobile devices?  Knowing which devices are interacting with your information would seem to be an essential part of business information security, yet smartphones and tablet devices often fall under the proverbial radar of IT or business management.  Actually, business management is likely among the base of users with the very mobile devices in question.

Are there ways to limit what information is accessible via these mobile devices, and is that data encrypted?  Consider also that data is sometimes at rest (like when it is just sitting on a hard drive) and sometimes in transit (like being uploaded/downloaded/transmitted over the wire).  In either state, the data should be encrypted in order to be more secure.

Is there a standard set of apps or services that users can enable, or is it pretty much personal choice?  Too often a user will innocently install a malicious app on their device, exposing the business to a variety of potential threats.  Creating strict policies around app selection and use is a really good idea, and finding a way to actually enforce them is even better.

The big issue is separation of work and personal apps and content.  Especially in small businesses where personal devices are the norm (well, not just in small business… Hey Hillary!) it is quite a challenge to create any useful separation between personal and business use.  The mobile device is often adopted as a personal choice of the user – who elects to invest their personal mobile device in their work – so exacting any real level of control in how the device is used is tough.  The security of the information is only as good as the security of the device, meaning that it is usually up to the device owner to decide if a password or pin is required.  Unfortunately and for the sake of convenience, there is often little or no real security on the device meaning there is no real security around the information on the device in the event that it becomes lost, stolen or compromised.

There are a lot of things that the business can do in order to improve the security of their business data in a mobile device environment.  Here are a few of the basics:

  1. Have defined procedures for what happens when a device is lost or stolen; make sure they’re followed
  2. Have a way to do a remote wipe of the device
  3. Make sure all devices lock after a period of inactivity, and that they have password or pin protection
  4. Have a mobile device use policy, and make sure all employees understand why it matters and agree to it.

Mobility and the Cloud – Managing “Bring Your Own Device” and Securing Company Resources

There are lots of reasons why businesses are adopting cloud and Internet technologies in great number, and supporting mobile workers is one of the big ones.  In order for traveling sales people or workers in remote offices to have access to business applications and data, many organizations are turning to hosted and cloud solutions to centralize systems and make enterprise-wide access easier to deliver and manage.

What many businesses are just now realizing, however, is that allowing individuals to use their own mobile devices to access corporate data is exposing the enterprise to new (and often unknown) risk with each and every device and app that gets used.

Most businesses recognize the need to secure corporate systems while allowing users to remotely access resources from home or mobile computers.

Many CIOs and IT managers are failing to address the vulnerabilities introduced through the proliferation of tablets and smartphones in the business. Some enterprises initially embraced the concept of “bring your own device” [BYOD], as it tended to encourage users to work from home or while on the road, increasing employee productivity and keeping workers more “attached” to their jobs – all without the business having to pay for the device.

With growing numbers of reported “rogue apps” and apps that secretly collect and pass data, the potential benefits of allowing workers to use their own devices is rapidly being overshadowed by the risks involved.

Earlier this year, Apple, Facebook, Yelp and several other firms were sued for privacy-infringing apps that, among other things, pillaged users’ address books. …but what if the app uploads a sales representatives’ contact list and the developer then sells it to a competitor? That’s a new type of data leakage that most organizations aren’t ready for.

http://www.cio.com/article/716368/Free_Mobile_Apps_Put_Your_BYOD_Strategies_at_Risk  

Phones, in particular, have not traditionally been viewed by most business owners as a primary platform for information theft or damage – other than when an employee uses one to tell someone something they shouldn’t.  But in terms of intrusion, data theft, application hacking and things like that… not so much.

But that was before phones got really smart.

Phones that most folks carry around now are actually computers with a great deal of processing and storage capacity, and as such are just as capable of running bad programs and being vulnerable to attack as their more obvious portable computer counterparts.  Perhaps they are even more vulnerable because of the “connected” nature of the device, because by its very nature it is geared towards communication of information, not just processing it.

It’s not that hackers and developers of exploits (or just bad code) are necessarily focusing on stealing your business data (well, OK, a lot of them are).  Maybe someone just got lucky one day, when they first realized that the employee phone was the “camel’s nose under the tent” which would get them inside, far enough to deliver access to confidential corporate information and data someone would pay for.  People tend to be the weakest element in the security chain, and exploiting vulnerabilities under the guise of “making things easier” for the user has been a highly successful approach (would you like to sign in with your Facebook account?).

..because attacks that target employees may well end up targeting the employer as well, even if the employer wasn’t the original target.

Whether it is intentional or not, the risk is very present, and every business and enterprise has a responsibility to recognize the vulnerabilities introduced with mobile device use and to do what it can to mitigate that risk.  It is also important to recognize that the risk is not a purely personal one, either.

Since the information held by most businesses also includes the information of others – customers, vendors, partners, etc. – it is essential that the business not expose itself to unnecessary problems (litigation, fines or penalties, or simply lost opportunity) caused by accidental leakage of confidential information belonging to 3rd parties.

For some businesses, the best answer may be to only allow use of devices the business provides, along with clearly written use policies and guidelines.  This approach allows the organization to determine which applications may be installed and to dictate how the device is to be used for business needs.

There are even solutions available which can assist businesses in managing the expenses related to mobile devices in the enterprise, addressing not only security and privacy concerns but also helping to optimize expenditures on mobile devices by monitoring contracts and usage, identifying underused agreements or overage charges, or even identifying contracts still in force which should have been cancelled.

For many businesses, however, allowing users to continue accessing business resources with their personal devices may be desirable for a variety of reasons, cost being only one of them.  If this is the case (as it is most often in small and growing businesses), it is important to make certain that users understand what is and is not appropriate device use, and to inform users on the policies relating to apps which may or may not be allowed and why.
