Mobile security concepts and technologies II.

Bring your own device
(BYOD) policies allow
people to use their own
personal devices to conduct
official business activities.
This does have a benefit for both the business and the people
who work there. The business doesn’t have to purchase the
devices, which saves on expenses. The people who take
advantage of BYOD policies get to use the devices that they
prefer. In addition to that, people no longer need to carry multiple
devices.
On the other hand, BYOD policies can represent some special
challenges for security personnel and system administrators that
may need to be overcome.

Data ownership.
» When employees use their own devices, who owns what data
can be a challenge.
• A clear understanding that company data and applications are
always company property needs be achieved.
– Device support.
» Before BYOD, the organization was responsible for supporting
mobile devices.
• Support for mobile devices may still be offered by the
organization; however, in most cases, the user is the
responsible party.
– Patch and antivirus management.
» The organization must determine how it will enforce patch and
antivirus management.
• This can be achieved through the use of NAC (network
access control) systems.
• The mobile device owner may be required to agree to keep
the device’s patch level and antivirus up to date.

Forensics.
» In order to ensure the security of the organization, the device
owner needs to agree that, if a security incident occurs, a
forensic analysis of his or her device can be done.
• This can become an issue with privacy.
– Privacy challenges.
» How to ensure the employee’s privacy, while at the same time
keep company data safe and secure may become an issue.
• Most organizations reserve the right to monitor all employee
activities (including those activities that take place on mobile
devices), which may conflict with personal activities on
personal devices.
– Onboard cameras/video.
» For security, it may be necessary to require that device owners
agree to disable image recording capabilities on their mobile
devices.
• The special challenge here is ensuring that they do so.

Architecture/infrastructure considerations.
» The organization’s IT architecture and infrastructure may need
to be modified to accommodate BYOD.
• May require an increase in the IP address range that is made
available through DHCP.
• May require supporting different operating systems (e.g.,
Windows or OS X).
• May require modifications to mobile applications to support
different operating systems (e.g., Windows Phone, iOS, or the
various versions of Android).
– Legal concerns.
» BYOD practices can bring other legal issues into play. This is
the reason that many organizations do not allow BYOD.
• When the wiping of organizational data off of a device also
removes personal data.
• The challenge is to how to separate personal use from
business use and personal data from business data.

Adherence to corporate
policies is a must if BYOD is
going to be practiced in the
workplace.
Without this adherence, corporate data and systems
can be placed at an unacceptable risk level. It is up
to administrators and security experts to ensure that
the policies are not only solid—from a security point
of view—but that they are also followed.
All users of an organization’s resources (e.g., data
and systems) should agree to follow the policies and
procedures. They should also understand the
consequences if they don’t follow the policies.

Acceptable use policies.
» A document that outlines what the organization considers to be
acceptable use of IT assets in the workplace—including non-
organizationally owned assets. It may include several sub-
policies.
• Acceptable use of the Internet.
• Acceptable use of email.
• Acceptable use of any mobile device (e.g., laptop or
smartphone) regardless of ownership.
– Onboarding and offboarding processes.
» Use of an NAC system can be implemented for the onboarding
process.
• NAC systems can perform a specific check of security items
before allowing a device to access the network.
• NAC systems can place the mobile device into the proper
network channel, depending on the type of device that it is.
» Offboarding processes must be put in place to help ensure that,
when an employee leaves an organization, no organizational
data is leaving with that employee.

BYOD policies allow employees to use their own mobile devices to conduct
official business in the workplace. BYOD introduces some challenges that
include: data ownership, device support, patch and antivirus management,
forensics, privacy challenges, onboard cameras and video,
architecture/infrastructure support, and several legal concerns.

The challenges of BYOD.
Summary
Creating a secure BYOD environment in a workplace can be challenging.
The first step is requiring adherence to corporate data and systems policies,
including acceptable use policies. Additionally, effective onboarding and
offboarding processes need to be in place to help ensure the security of
corporate assets.
