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 Too many businesses say they have a “security and use” policy in place, yet it is outdated and doesn’t reflect the actual tools or processes currently in use.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.

Mobile IT for Contractors and Builders (for every business, actually)

The Trend Is Up For Single-Family Housing Market

Even as lot and labor shortages and other supply side constraints continue to impact builders, and while the cost of building materials continues to rise, the demand for housing continues to increase at a fairly consistent rate. “November’s builder confidence reading is close to a post-recession high-..” NAHB Chairman Granger MacDonald said in a recent release.

Supported by rising homeownership rates and a reduced number of available homes for sale, the trend up is expected to continue.

Increased competition for new business opportunities in the building market require that home builders and developers leverage available technologies and IT resources to improve operational performance and increase the profitability of every project. Applications for better estimating, project and cost management and accounting represent the foundations for information management and supporting the flow of work.Extending workflows to embrace mobile workers and remote offices is the next step to developing an efficient anytime/anywhere business. 92 percent of U.S. construction executives believe that technology will fundamentally change their businesses, and help them bridge the performance gap, according to KPMG’s Make it, or break it – Global Construction Survey 2017 report.

Collaborating while on the go and exchanging ideas and concepts quickly helps businesses be more agile and better-able to meet changing customer needs. Remote and mobile access provides businesses with mobile office options that allow users to get their jobs done no matter where they happen to be.

Business moves at a fast pace and working smarter means implementing the right IT to keep moving up with the demand and creating sustainability for leaner times.

The nasty surprises hackers have in store for us in 2018

“Hackers are constantly finding new targets and refining the tools they use to break through cyberdefenses. The following are some significant threats to look out for this year.

More huge data breaches

The cyberattack on the Equifax credit reporting agency in 2017, which led to the theft of Social Security numbers, birth dates, and other data on almost half the U.S. population, was a stark reminder that hackers are thinking big when it comes to targets. ..

Ransomware in the cloud

… The biggest cloud operators, like Google, Amazon, and IBM, have hired some of the brightest minds in digital security, so they won’t be easy to crack. But smaller companies are likely to be more vulnerable, and even a modest breach could lead to a big payday for the hackers involved.

The weaponization of AI

This year will see the emergence of an AI-driven arms race. Security firms and researchers have been using machine-learning models, neural networks, and other AI technologies for a while to better anticipate attacks, and to spot ones already under way. It’s highly likely that hackers are adopting the same technology to strike back…”

Centralize and Secure Business Applications and Data

laptop drawingThe portable computer is an essential business tool for day’s mobile workforce, having the power and portability to meet the demands of executives and professionals working away from the office.  While executives and mobile professionals get the applications and data they need to keep productivity high, carrying business data on devices outside the network introduces significant business risk.

There are studies which estimate that as much as 80% of the data a small business owns (data like customer files, contracts, product information and financial data) is copied to or stored on portable computers.  When valuable business data is lost or stolen, the business can be exposed to a variety of problems – loss of revenue being just one. Losing track of business data can create legal issues, too. Customer privacy may be compromised, sensitive information could be exposed, or confidential plans might be made public if a business doesn’t take the right steps to secure its data.

It isn’t just the possibility of loss or theft which increases risk when data is copied to portable computers – the increased vulnerability of the information sits with the likelihood that the user will access unsecured networks, launch non-corporate applications, access private email accounts and perform other non-business related tasks with the computer because they have more access than with a fully secured corporate in-office desktop.  User behavior is often what puts corporate data and assets at risk, regardless of the policies that might define correct and acceptable procedures. It is very easy for workers to unknowingly lose and leak data, and when the data is present on the portable computer it gets even easier.

A 2014 study commissioned by Cisco Systems found that employees around the world continue to engage in “risky” behaviors that put business and personal information at risk:

  • The majority (70%) of surveyed IT pros believe that as many as half of their data loss incidents are due to authorized program installations
  • 44% of employees share work devices with others without supervision
  • 39% of IT professionals have dealt with employees trying to access unauthorized parts of the company’s network
  • Almost half of the employees admitted to copying data between work and personal computers when working from home
  • 18% (up to 25% in some regions) of employees shared passwords with their co-workers

Companies must not only protect their data for their financial well-being, but must recognize their legal obligation to protect much of the information, as well.  The risk extends beyond the walls of the enterprise, to vendors and customers and consumers whose information may be stored in the company data. Additionally, portable computers exposed to malware and virus attacks are likely to pass the bad code to other systems they come in contact with, introducing not just risk for the recipient but liability for the infected laptop owner.

Where mobile computing brings huge advantages to today’s business, owners would do well to consider the benefits of enabling mobility through the use of server-based and hosted computing models. Rather than installing software and copying data to PCs and mobile devices, workers should be able to access a central system where the applications actually run. IT management is more efficient and security is easier to enforce when applications and resources are contained exclusively within the corporate boundary, even if they are accessible from without.

Virtual desktop and remote application solutions offer features that address a variety of potential risk factors as well as enabling improved management and security of IT assets.  Centralizing and securing applications and data resources at the server allows businesses to deliver the mobility and functionality users need while enabling the information security and management the business demands. This is a foundation upon which remote desktop and remote application technologies were built, allowing users to have the real-time access to applications and data with full functionality and desktop modality, but without the requirement to install, manage and secure applications and data on the individual devices.

Big Data, Analysis and Business Intelligence

Big Data, Analysis and Business Intelligence

big dataThere is a lot of talk among IT professionals of “big data”, and discussions at many business conference tables center on how the organization might find greater benefit and advantage from the intelligence buried in the business systems and information.  It is a two-part problem, where the collection and the analysis each play essential roles in developing real business intelligence.

“So what’s getting ubiquitous and cheap? Data.

And what is complementary to data? Analysis. ..”

Hal Varian, Chief Economist at Google and emeritus professor at the University of California, Berkeley
“Hal Varian Answers Your Questions,” February 25, 2008 (http://www.freakonomics.com/2008/02/25/hal-varian-answers-your-questions/).  BUSINESS INTELLIGENCE AND ANALYTICS: FROM BIG DATA TO BIG IMPACT; MIS Quarterly Vol. 36 No. 4, pp. 1165-1188/December 2012

The information technology and systems in a business support the operation.  Software and computers help people do their jobs, and the information collected in and generated by those systems becomes the foundation for developing business “intelligence”.   Today, businesses must reach beyond their own direct operational support systems and consider the full realm of data to be collected, including IoT sensor data or social media data.

Business intelligence is gained from the analysis of the critical business data – analysis which helps owners and managers make better and more informed decisions which are based on an understanding of the business and market.   Business intelligence was a term popularized in the 1990s, but the key was the analytical component (business analytics), which gained focus in the late 2000s. Today it is big data and big data analytics, where organizations are working with massive data sets not previously even imagined.

“…one of the most significant challenges facing enterprise IT teams today is how to efficiently support and enable the “science” of big data, while providing the confidence and maturity of more traditional (and often better understood) infrastructure services.”

http://www.datacenterknowledge.com/archives/2015/05/26/hadoop-big-data-storage-challenge-overcoming-science-project/

The volume and velocity of information collection is ever-increasing even in the smallest of businesses, creating a great need for tools which can structure and correlate data so that it might render some insight.  Simply storing and managing these huge and growing data sets has become a challenge, and there isn’t one right way.

Once the business has the data, then it must find a way to analyze the data, which generally involves also applying visualization tools. Many IT departments are feeling pressured in the development of new skills and capabilities around data collection and management, yet it is more frequently the business user who provides the analysis and applies visualization tools to the task.

“Data collected by the Aberdeen Group, found that employees in organizations that used visual data discovery were more likely to find the information they need, when they need it. These same companies were able to scale their use of scarce IT skills more effectively.”

http://www.tableau.com/learn/whitepapers/visualization-set-your-analytics-users-free#0vXrkWZbizxyutw

The use of business intelligence and advanced analytics continues to grow in every segment of the market – from small business to enterprise – and plays an increasingly important role in supporting business success.

Until this point, most businesses didn’t have the technology or the data to enable significant quality or business transformation, but the times are changing and deployments of data collection, analysis and visualization software and tools are expanding with it. This is a fundamental aspect of business digital transformation and fuels the next step, where intelligence is applied to conditions revealed in the data and activities are automatically performed guided by that intelligence.

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.
