4 Personal note The mobile (smart phones and tablets) devices are still not frequently used or are unmanaged. Many companies don't trust external devices and most of IT managers don't want to implement BYOD (the proper awareness is missing). Most of companies don't have clear vision about usage, benefits and controls over mobile devices. They don't know where it can save money. Most of them also think they can adopt either company managed devices or BYOD - implement both based on data characteristics or type of usage has not been really evaluated. The only massive implementation was remarked in global companies 3

5 Enterprise Applications Extended to Mobile Devices New opportunities for sales enablement, customer & partner interaction, employee productivity, business process acceleration, & instant access to key analytics. Approvals Dashboards Top Management Contacts Workflow Middle Management Calendars Reports Scheduling & Dispatch Time & Expense Operations Transactions 4

7 Bring Your Own Device Employees increasingly want to use their favorite mobile device for personal and business use. They want to store personal data and install Internet games on devices they are also using to access enterprise applications and data. If employees purchase their own device and plan, this can reduce telecomm costs, however it creates several business challenges and security risks. BYO Rationale User Perspective: Desire for one device and phone number, not two Desire to fully own the decision process when selecting a personal device Desire for the latest gadget (especially younger workers) Local store offers better selection than the IT department Company Perspective: Increased staff productivity due to better morale & hardware Potential to reduce hardware, monthly service, provisioning and ongoing support costs IT Department Perspective: Potential for reduced IT staff workload as users move off employer provided devices and onto BYO devices BYO Challenges Security Enterprise data confidentiality, integrity and availability Liability for personal data (wipe, central storage) Defining and enforcing the security perimeter Application Splintering Impact of heterogeneous device environment on application development and support requirements Support Device certification, provisioning and management Cost Potential loss of corporate-level volume discounts because of personal purchase. Enterprises should align user expectations, IT capabilities and security policy. Failure to act may increase security risk as unmanaged mobile devices continue to connect to the enterprise network. 6

11 Mobile Device Security Risks High-level mobile device security risks are not different from traditional IT security risks. The real challenge is that mobile devices introduce new vulnerabilities and attack vectors for traditional risk areas. Topic Governance Information Security Privacy / Data Protection Business Continuity Management Change Management Risks No clear governance framework Lack of understanding of risk Ineffective access controls - mobile devices and 3 rd party partners Prevention of malicious attacks (incl. cyber) Ineffective processes for malware/security updates Lack of monitoring processes to respond to ongoing threats Unauthorized access to personal data Compliance with cross border laws, offshore storage Data leakage Inability to recover data Availability of critical resources Change control processes Testing prior to implementation Access to the production environment 10

12 Research by NSA The new generation of smartphones is more resistant to some types of cyber attacks that have proven extremely damaging, such as spearphishing and user-installed malicious software. At the same time, their use involves acceptance of other risks such as attacks via the cellular network, and a greater likelihood of data loss due to lost or stolen devices. Overall, vast numbers of obsolete desktops are likely to continue to be attackers front door to networks, although smartphones do permit highly motivated adversaries to carry out highly-targeted attacks against senior leaders. NSA continues to partner with industry to develop technological enhancements that prevent and detect such attacks. 11

13 Managing Bring Your Own Device Risks 1. Minimize the amount of stored data on the device 2. Use virtualization or sandbox solutions 3. Establish a policy and end user acceptance agreement: Appropriate use Surrender Wipe policy and risks Monitoring and data archiving Minimum configuration requirements Minimum security requirements Disposal 4. Keep unauthorized devices off the network (network monitoring tools) 5. Continuous and effective user awareness education 12

15 Mobility Security Framework Mobile security risks include device loss or theft, data loss, data compromise, credentials theft, malware, unauthorized network access and direct attacks on devices and exposed application servers. To protect your organization, you must extend your enterprise security policy, security strategy and core security objectives (confidentiality, integrity, availability) to each layer of the mobility stack. Mobile security solutions have a technology, process, and human resource component.

16 Addressing Mobile Security Triggers Security Management Privacy BYO App Security End Point Security & MDM Training & Awareness Triggers Lack of clear governance framework Rapid introduction of mobile devices Complying with local & international legal requirements Auditing corporate/personal devices Corporate liability Managing the device lifecycle Enforcing the security perimeter Data leakage prevention Malware and insecure apps Security update process Preventing unauthorized access Managing different devices Enforcing policies & baselines Compliance with security policies Awareness initiatives to effect behavioral change Solutions Create mobile strategy & governance model, involving all stakeholders Develop appropriate use & security policies Privacy Impact Assessment (PIA) Define mobile device management and data protection requirements Conduct audit on BYO strategy Develop app configuration baselines Business app store assessments Perform secure code reviews Create device configuration baselines Conduct end point security audit Perform device security assessments Develop & conduct security awareness program with organizational change initiatives 15

17 Mobile Device Management Mobile device management provides full life cycle support for mobile devices, mobile applications and associated data stores to help ensure: Applications, patches, security agents, etc. are properly provisioned Data is automatically backed up and protected at all times (at rest and in transit) Devices are configured correctly and protected from threats IT can remotely correct problems, wipe data and disable the device This requires systems, defined processes and skilled resources in multiple areas: Provisioning Asset & Configuration Management Initial mobile device & mobile apps request Map user & device to a user group & mobile applications Wireless service provisioning Network access controls provisioning Image the mobile device (apps, settings and security agents) Application distribution On-device isolation of user apps/data from enterprise apps/data Physical asset tracking & accounting Software license/app download accounting & management Hardware repair/replace & warranty issues End user data backup Mobile data plan expense management Device configuration management De-provisioning apps, devices and accounts Security User authentication Device, mobile app and enterprise app access control Stored data encryption and end-to-end encryption Application whitelist/blacklist Content filtering and malware protection Security event monitoring, logging and response Data leak protection & removable storage control 16 User Support Password reset Remote troubleshooting Device/app/data restore Device support roadmap Trouble ticketing and support knowledge database Trend analysis Help desk training on devices and apps

18 Deloitte MDM Solutions Review Product X Pro s Management ease of management, and configuration Ability to wipe devices remotely Jail break/rooting detection when Product X application is on the device Reporting capabilities on device that have been enrolled in Product X such as inventory and package tracking Multi-Tenant functionality available (at an extra cost) Web enroller that does not require Product X app Device administrator can send a command to allow end users to reset their passcode if they forgot Con s End user can remove policies No support for Windows Phone Limited Android Support Cannot remote wipe or encrypt SD cards on Android Able to remove control, but no partial wipe of the device is available. Complex enrollment process Ownership tracking not accurate if configured by IT Web console is slow and cumbersome, updates scheduled for early next year Possible for any person can enroll a rogue device once the enrollment code is provided and possibly gain access to corporate information No app store functionality Device lock feature is of no use since the end user will know the passcode Cannot push a background image or other data 17
