Developing and enforcing a BYOD policy is important for companies using mobile devices. The document discusses a mobility survey that found 97% of respondents feel mobile policies are important, yet many organizations still do not have policies. It also covers the top 3 mobile security practices of authenticating users, controlling access to resources, and protecting corporate data. Implementing an effective BYOD policy presents challenges in finding the right balance of security controls without upsetting employees.

5. Criticality of Mobile Policies
• It starts with
the policies
– 97% believe
it's important
• Yet so many don't
have mobile policies
– Improvement from
last year (58%)

6. Ends of the Spectrum
• Most stringent
– 24% do not permit personal devices to
access company resources
• Most lenient
– Besides no policy at all 
– 14% let employees secure their own
mobile devices
• Somewhere in between
– 21% manage employees' devices
– 27% use mobile sync with minimal
device management controls

10. Challenges
• How should companies implement
authentication and access controls?
– User credentials?
– Location?
– Device type?
– Applications?
• Where should organizations "touch"
employee devices?
– Device?
– Applications?

11. Protecting Corporate Data
11

12. Challenges
• How should employers ensure
protection of data on lost/stolen
devices?
– Wipe sensitive data?
– Wipe entire device?
– Locate the device?
– Lock/Disable the device?
• How should fraud controls be
implemented?

13. Conclusions
• Policies are important
– 37% still don't have them
– Many are developing policies after
building their controls
• Companies are most interested in
– Authentication
– Access to resources
– Data protection
• Challenges with BYOD
– Finding a balance in controls
– While not upsetting employees too much 

15. Bring Your Own Device
(BYOD) Policy
Benjamin Wright
Attorney & SANS Institute Instructor

This is education, not legal advice.

16. Bring Your Own Device (BYOD)
• Rules for employees using own
laptop, tablet, smartphone,
webmail services for business
• Controversial topic; no perfect
policy exists
• See discussions:
http://goo.gl/txlCU,
http://goo.gl/7bEAQ,
http://goo.gl/QX6Uz,
http://goo.gl/edSFF

17. Subpoena for Employee’s
Home Hard Drive
• Local government employment
dispute
• Plaintiff able to subpoena hard
drive of manager’s home
computer
• Wood v. Town of Warsaw, N.C.,
No. 7:10-CV-00219-D, 2011 WL
6748797 (E.D.N.C. Dec. 22, 2011)

18. Employer Liability for Security
• Massachusetts 201 CMR 17.00:
PII on mobile devices must be
encrypted
• Cal SB 1386 - many breach
notices because of stolen,
unencrypted laptops (e.g. Guin v.
Brazos Higher Education)

19. $1.5 Million Fine +
Costly Security Upgrades
• Unencrypted patient data
• stolen laptop
• Massachusetts Eye and Ear
Infirmary (hospital)
• HIPAA penalties imposed by Dept.
Health and Human Service

20. Employer Incentives
• Device and service monitoring
• Data wiping (selective or whole
device)
• Encryption
• Confiscation if monitoring
identifies device or service as a
risk or threat

21. Policy/Agreement Challenges
• Warning employees
• Getting employee consent
• Employee privacy
• Liability for damage to employee
data, device or service

22. BYOD Policy – Sample Language
• http://goo.gl/19idt
• Workable policy will come from
negotiations among stakeholders
• This language tilts toward needs
of employer

23. BYOD Policy
"Employees are informed that when they
create electronic records or work product in
the course of their work for the Company,
the records and work product belong to the
Company."

24. BYOD Policy Continued
"When an employee uses his or her own device,
such as a computer, a digital tablet or a
smartphone, to connect to Company information
resources, then the Company reserves the right
to take security measures relative to the device,
including but not limited to inspect the device and
. . ."

25. BYOD Continued
Employees are informed, and employees agree, as follows: If the
Company takes control or possession of a Device or Service, or
takes security measures relative to it, then:
(a) the Company might not return the Device or Service;
(b) the employee is entitled to no compensation for loss of use,
control or possession of the Device or Service;
(c) the Device or Service could be damaged, the employee could
lose data and the employee’s data could be disclosed to others.
The Company will not be liable or responsible for such damage,
loss or disclosure.

26. BYOD Policy Continued
"As a matter of honor and reputation -- but not as
a matter of legal liability or obligation – the
Company aspires to be forthcoming with
employees as a whole about the practical impact
of this Policy on employees over time."

Account Detail Request
Has he accessed between 00:00 –
03:00 in the last two months?
Behavioral Patterns
Has he used this device more than
20% in the last three months?
Does subject live in same
geography as requestor?
Does he usually perform
account lookups?
Valid Credentials given from
Get Account Information: outside network, but already
logged in from inside network.

isAuthorized(user = Bob Doe, Acme Corp
Device = iOS 5.0, non-registered
Location = 37.53043790,-122.26648800
customerId = 99999
action = getCustomerDetail)
HTTP / REST / SOAP / OAuth Clients
Customer Service
- getCustomerDetail
Request
- updateCustomer
- deleteCustomer…

{ “CustomerDetailResponse“:
{ “customerID”: “99999”
“name”: “Sally Smith”

38. Oracle Mobile Access Technology
• Oracle Enterprise Gateway
– Enables Mobile Application REST API’s and protects API’s,
webservices, and SOA infrastructure from external threats and
invalid / suspicious requests
– Extends Access Management with authentication, authorization,
audit to REST API’s, web services
• Oracle Access Management Suite+
