Speakers Sarkis Daglian Sarkis Daglian has been with UC Irvine since 2005 and is the assistant manager of

OIT’s Desktop Support Services. He has been lead of OIT’s mobile support effort for the past two years defining usage on the campus, making recommendations that empower the mobile user, and coordinated the effort to bring the Airwatch mobile device management system to the campus.

Isaac Straley Isaac Straley has been with UC Irvine since 2005 and is the campus Information

Security Officer. He is the lead for information security and privacy, data risk management, data breach incident response, and security/privacy compliance. He has been recognized for his work in information security, including receiving the 2008 3rd place Award for Excellence in Criminal Investigations from the International Associations of Chiefs of Police. In addition to his work on campus, he actively participates in UC-wide and EDU-wide security initiatives, such as recently serving as Chair of the UC IT Policy and Security committee.


Assumptions

More people will use mobile devices •  Cisco predicts more mobile devices than people

on Earth by end of 2012

Connectivity will soon be near ubiquitous •  We use mobile for work and our personal lives

Applications and data storage will continue to be abstracted to the cloud.


What to do about BYOD? “Bring Your Own Device” •  94% of users would be “very frustrated” if their company wiped

their personal data off of their mobile device •  43% would be “very unwilling” to give up the user of data-

intensive apps such as Pandora or Spotify on their personal devices in exchange for access to corporate information

•  64% of users would be “very frustrated” to have to enter an enterprise password every time they wanted to access their favorite apps, such as Facebook

•  49% of users would not opt for enterprise access if they had to give up iCloud or Android Backup Manager for their personal device

Bring Your Own Device (BYOD)

PRO • User flexibility • Less devices for users • More advanced devices on the network • Devices upgraded more frequently that organization cycle

CON • Less control of devices • Data security compliance • Who owns the data? • How will you recover data if someone leaves?


BYOD is not the Question

It’s already here. “How do we secure personal devices?” “How do we secure the data?”

•  The policies go with the data and the risk, not the device


Defining Terms: Mobility

Data •  Data can travel with the device •  Data can be accessed from a variety of endpoints •  Data may be stored in a variety of places

Connectivity

•  Anytime and anywhere •  Unsecured wireless networks •  Remote access


Defining Terms: Security

Confidentiality: Only authorized users can access the data Integrity: The data “are what they are” Availability: The data are available and accessible when we need them to be


The Mobile Landscape

The Dominant Players - iOS - Android

The Other Guys

- Windows Mobile - Blackberry


Mobile Device OS Market Share


Apple vs. Android Ecosystem

Closed vs. Open - Apple tests and must approve every application posted on their app store - Android allows any application to be available for installation without vetting. Keeps platform truly open.

Cloud computing


The Mobile Landscape

Cloud Storage •  iCloud •  Google •  Dropbox

Far Reaching Digital Footprint Beyond Storage

•  Privacy: Social media, Geolocation •  Other Apps: Notes, project management, videos


Why this matters to developers

Need to understand the possible environments and potential consequences

Example: Storage •  What happens if data are cached locally? •  If dev is using third-party storage, do you know

where it is being stored (e.g., continental U.S.?) Example: Authentication

•  Integrate authentication so user has reasonable access limits

•  Too much auth is just as bad as too little


Examples of Breaches

Laptop theft •  SF Police video

Apple-Amazon hack / Gizmodo journalist Android Malware Linked In Breach


So how do I protect my mobile data?


Security & Privacy Guiding Principles Stewardship and Accountability

Everyone has a responsibility to protect information and individuals are held accountable.

Risk Management Information must not be stored without understanding and formally mitigating or accepting the risk.

Business Ownership Information security is owned by all levels of the organization, not just IT. Senior managers are involved in determining and accepting information security risk.

Privacy Privacy and security is not a "zero-sum game." All aspects of privacy, including academic freedom, are weighed and incorporated into security practices.


Architecture Principles

•  Defense In Depth •  Least Privilege Access •  Segmentation •  Segregation of Duties •  Accountability •  Do Not Trust Services •  Simplicity •  Reuse •  Secure Default


How to Manage Risk

Risk Management

Identify Threats

Identify Vulnerabilities

Assess likelihood and

impact

Implement protective controls

Approve risk

Measure control

effectiveness


Levels of Risk Low: Any data should have some protection on it Medium: Unauthorized access to or disclosure of information in

this category could result in a serious adverse effect, cause financial loss, cause damage to the University's reputation and loss of confidence or public standing, constitute an unwarranted invasion of privacy, or adversely affect a partner, e.g., a business or agency working with the University.

High: Any confidential or personal information that is protected by law or policy and that requires the highest level of access control and security protection, whether in storage or in transit. The term should not be confused with that used by the UC-managed national laboratories where federal programs may employ a different classification scheme.


Mobile Device Best Practices •  Ensure your device’s operating system is up to date •  Set up a passcode lock or pattern. The more complex the better •  Set an auto-lock time •  Set your device to auto-erase its contents after too many

unsuccessful password attempts •  Only install applications from trusted sources •  Use GPS tracking software

Optional Steps •  Enable mobile browser fraud warnings •  Forget wifi networks to prevent automatic rejoin •  Keep Bluetooth turned off when not in use

What are the best policies for BYOD?

Protecting the data is everyone’s responsibility The policy goes with data, not with the device Security is not a binary state

•  Manage the risk and apply reasonable protections

•  Involve stakeholders in making risk determination


How to Enforce BYOD Controls

Rely on users to make determination •  Easy to implement, low level of assurance

Tell users requirements, ask for attestation •  Good for many risk scenarios, joint effort between

data owner, IT, and users Use technical controls to enforce

•  For higher risk situations, attestation is not enough


What are we trying to accomplish?

•  User and Device Provisioning

•  Policies •  Backup/Restore •  Updates •  Diagnostics •  Software

Installation / Restrictions

•  Asset tracking and management

•  User support •  Remote wipe and

remote lock •  GPS tracking? •  Exception process



UCI Airwatch Implementation

Medical Center – Bradford Networks appliance and Airwatch Devices at Med Center register with Bradford NAC, which authenticates a user and places them in the appropriate group and minimum security configuration. Those requirements are then pushed from Airwatch.

Main campus – Airwatch Devices under Athletics IT must enroll in Airwatch to have security protocols enforced on them to be NCAA and HIPPA compliant. Desktop support clients are also using Airwatch as a means to enforce data security guidelines


Take Aways

•  The world is now mobile and BYOD is here •  Professional and personal data now reside and are

accessible on the same device •  Protect the data, not just the device or the application •  Involve everyone! •  Assess the risk •  Set guidelines, policies, and procedures to govern

levels of security required for different types of data •  Determine how to enforce security requirements,

using an MDM when appropriate
