Today, whether you like it or
not, whether you allow it or not, every organization has employees accessing
office information via BYODs (“Bring Your Own Device”). Allowing access
obviously opens up security flood gates that many IT may not be aware of at all.
Let me discuss a bit about what is happening in the world today and briefly
touch upon visibility of BYODs, talk about the new trend what is called BYOA
and COPE, and then talk a little about the security for these BYOds.
A survey conducted by B2B
International in July 2012 reveals that 33% percent of companies allow their
staff unrestricted access to corporate resources from their smartphones or
tablets. 38% of companies apply some kind of restriction on smartphone use:
these include bans on access to certain network resources. A further 19% have a
complete ban on the use of mobile devices for work activities. But only 11% of
companies currently use some kind of BYOD management tools to ensure compliance
with corporate security policies. 34% of those surveyed think that the use of
personal devices presents a threat for business, and another 55% frequently
think about how to reduce the risk. This increased focus on mobile devices from
IT specialists is probably explained by the fact that 23% said they had faced
the loss of business data due to the loss or theft of mobile devices.
Despite all the risks
involved, only 9% of companies are planning to introduce a strict ban of their
usage (and another 91% will be looking at solutions on how to manage these
BYODs and the risks and the security issues better). . Interestingly, 36% of
the IT specialists surveyed are sure that, irrespective of any new measures,
the number of user devices in the workplace will only increase.
If this is all about BYOD, there
is a new thing coming up called BYOA or what is called “bring your own
applications”. BYOA cuts costs, reduces training requirements since users
already are familiar with their apps and it will be relatively easy to
integrate the apps into the organization's IT infrastructure. Agrees Edwin
Schouten, IBM's Cloud Services Leader for Global Technology Service and sees
lots of positives. Whether the IT likes or not there will be a
plethora of applications running on corporate network driven by the employees
or the consumers rather than IT – something IT needs to adopt, accept and move
on and work more on how to secure my network inspite of BYOD and how to
integrate user apps into the IT infrastructure securely rather than trying to
put restrictions on the usage or option of the software or the apps. Basically
consumerization of IT will be an unstoppable of change. This (BYOA) will be
very familiar to the original impetus of BYOD. Infact the BYOA trend also is
getting traction in Europe. The
Telegraph takes a look at the issue. To quote telegraph on this, “Bring
or choose, the trend is for employees to use such tools for storage note-taking
and free apps such as Skype for voice communications. The numbers are
already impressive. Yammer has more than five million corporate users, Google
apps has 40 million active users and Dropbox has more than 50 million users”
While we are still digesting
the BYOD and BYOA, another new concept is coming up which is called COPE or
what is “Corporate Owned Personally Enabled”. In this scenario, the device itself is owned
by the organization, but apps come from the employee. COPE , ReadWrite
Enterprise has a story essentially
works like this: the organization buys the device and still owns it, but the
employee is allowed, within reason, to install the applications they want on
the device, be it smartphone or traditional computer.
Basically general consensus in
the CIO world is that IT should stop controlling BYOD or BYOA or COPE but start
working on how to take advantage of this to reduce costs and bring in new tools
to make sure the organization is secure and the consumer apps are well
integrated. Many IT organizations probably can say that employees are not
allowed or not deploying their personal devices (BYOD) on company’s network but
according to the survey, 84% of smartphone users are also using their devices
at work. While BYOD could mean increased productivity for your employees, it
also is a potential threat to your overall network be it performance or
security or the delivery of the applications running on it. According to
ESG, 88% of enterprise organizations today allow for BYOD and personal use
of devices while at work. Also mobile workforce enablement was ranked as a top
ten IT priority by respondents to the ESG 2012 IT spending intentions research
survey. Furthermore, additional ESG research shows that 88% of enterprise
organizations with BYOD initiatives surveyed allow for mixed personal/work use
on employee owned devices.
So what are the effects of
allowing BYOD without checking? Yes there is a huge gain in productivity,
drastic cut is costs, employee friendly etc. but leaves open a huge security
hole, huge risks, excessive bandwidth load and in all impacting performance and
security of business critical applications. If you are not ready for this
additional network bandwidth consumption, these devices will actually start
impacting negatively on productivity and revenue. Imagine all of your employees
watching Netflix, or YouTube or downloading video or books or music or watching
anything live at business hours. Due to this, performance of the corporate
network can drastically come down impacting the performance of the corporate
applications and employee productivity. For example, just one employee watching
an HD Video (streams at 1.5MB/sec) could consume an entire T1 link.
Equally problematic, these BYOD
devices have the ability to transfer items out of the enterprise. Not that it
cannot be done via other computing devices but just the way apps are integrated
into BYODs and the ease of use has made life much easier and sharing that much
simpler. New applications such as
Dropbox or iCloud enable employees to share files and content outside of the
enterprise. This represents a potentially serious security threat depending on
who is sharing information and what information is shared. Organizations need
to get a handle on what is going on in their BYOD environment be it related to
risks, network and application performance, potential data breaches, or lost
employee productivity.
Some
of the things NOT recommended are first to blindly upgrade or double your
bandwidth and second, to buy any security tools without knowing where the hole
is. When
applications run slowly, the network typically gets blamed. Without any
visibility into the network, and hence not knowing what actions are performed
and by who etc., organizations tend to increase the bandwidth and hence run
into higher operating costs. Worse, it does not take much time to clog the new
bandwidth!! Without visibility and a baseline network performance, BYOD
initiatives could prove to be detrimental to the network and the business.
Same
goes with BYOD security too. Without visibility that is without the info such
as what is happening, who are accessing what, how many devices and what types
and who have access to what and what devices are connected via corporate
network and what security holes they are creating, don’t deploy the tools else
you will be band-aiding the wrong places. You need to know many things such as
where are your sensitive files are, who are accessing them, who are accessing
cloud services, who are using services such as Dropbox and what files are
loaded and shared, is someone or some device accessing sensitive information
etc. Visibility gives you the power of quickly identifying all these and the
problem sources, data security holes and can make informed intelligent
decisions on how to protect and what tools to buy. Once you are monitoring the
environment, administrators will know exactly what is happening, organization
can intelligently implement policies to ensure right people have access to
right sites and files and effectively enforce and monitor the access.
The summary J
To
handle various computing devices (BYOD) and numerous apps (BYOA), organizations
first need to have visibility into the network and on these devices and the
apps that are running on them. This granular information will enable
organizations to understand which users, which apps, what access are being used
or abused across the corporate network and corporate resources. Based on this
visibility, organizations can implement policies regarding the right usage of recreational
and business use of these devices and also get in the right security tools to
ensure corporate critical info is protected. Failing to gain this visibility
could lead organizations to unnecessarily overprovision network capacity to
support employee recreational use or put tools which might not really fix the underlying
security issue. As they say “knowing is everything”.
There
are many companies that offer BYOD visualization and security tools (both
intrusive agent and also non-intrusive agentless) and by deploying such tools,
organizations can say yes to BYOD & BYOA and still retain control, ensure
higher employee productivity, lower cost and make sure no productivity
distraction happens nor any security holes left.

BYODing” J
