6 Your worst BYOD Nightmare is to not realise that the cord has already been cut: From smart phones to tablets to laptops, mobile technologies have become a standard part of work life, offering productivity and efficiency gains as well as enhanced services for customers. The ways in which these technologies interweave work life and personal life raise a major security challenge for most organizations. Meanwhile, Cybercrime organisations aggregate and mine user data for new attacks In this new world, old-fashioned Information Risk Assessment methodology still apply Topics to be discussed over the next few minutes: o Risk Assessment in a Mobile world o Mobile Reference Architecture on commonly used components of mobile in a corporate landscape o Mobile profile to understand the scope of your clients mobile environment and related vulnerabilities o Threat, Vulnerabilities and Controls database to help identify threats that apply to your clients situation and which controls would be suitable to mitigate the risks 6

7 BYOD is a reality, requiring executive action Mobility comes with risks that are different from the standard enterprise IT environment. Mobile technologies require a different response from the executives, charged with defending their enterprise from cyber attacks and enabling the enterprise to improve operations and expand their markets more effectively Few devices know more personal details about people than the smart phones in their pockets: phone numbers, current location, passwords, personal details etc and vulnerabilities abound. They are prone to being lost or stolen, yet very few are encrypted. Unlike desktop or laptop computers, smart phones have customized hardware architectures, and even open source operating systems like Android which comes in many versions. Often, it s up to users to accept and install the patches, resulting in an inconsistent mobile device security posture Business needs demanding rapid Mobility enablement: CIO involvement is key Mobile malware can enter a device at many points: An end-to-end approach is necessary 7

9 Waking up from my BYOD nightmare where am I? Waking up: Risk Assessment helps us find as-is, and desired to-be Security Risk assessment such as ISO 27005:2011 is mapped to the a project delivery lifecycle. After the assessment, a remediation project is typically started to treat the risks identified, reaching a desired to-be status less nightmarish. Project Management Plan Analyse Design Build & Test Risk Assessment Initiation Establish Context Establish Risk Assessment Context Identify Current Landscape Threats, Vulnerabilities & Existing Controls Inherent Risks Analyse Residual Risk Evaluate Evaluate Residual Risks Suggest Controls Document Assessment Results Transition to Remediation Project / Risk Management Operations Remediation Approach Cost Benefit Analysis Control Implementation Treat Implement Controls Validate & Test Implementation Measure Performance Transition to Deploy and Support Phases Information Risk Assessment Project Scope Follow on remediation Project scope 9

13 Controlling BYOD: From woe to go Our experience: Core capabilities are required for managing a Mobile solution 13

14 From woe to go: Layered approach The Device Use an end-to-end approach, from manufacturing to disposal Assume many mobile devices used by employees will not be secure. The Application Provide layers of security If someone bypasses one security measure additional security protects data. The Back-end system Consider multi-factor authentication (e.g. biometrics plus password) and host level security and monitoring. The Network Secure and monitor corporate wireless networks Demand better security from wireless network service providers 14

15 From woe to go: Standardised approach TVC database Accenture developed a solution that takes Assets, threats and vulnerabilities related to mobile environments, cross-referenced and mapped to the reference architecture. Likewise, suggested controls are listed to recommend defense in depth mitigations. Out-of-the-box, the August 2012 release of the Threat, Vulnerability and Controls (TVC) database contains following information: Information assets 43 mobile threats based on various threat reports 37 vulnerabilities based on vulnerability research for the components in the mobile profile and reference architecture 40 information assets based on vulnerability research for the components in the mobile profile and reference architecture 70 controls and their attributes based on analyst reports for functionalities of top-of-class solutions and mobile security controls research Elements are cross-referenced in the structure depicted on the right Additional elements are added per quarterly release Vulnerabilities Threats Reference architecture Controls 15

17 Safeguard controls for mobile devices There are 2 approaches to safeguard mobile devices Mobile Device Management (MDM) Secures, monitors, manages and supports mobile devices deployed across mobile operators, service providers and enterprises. MDM functionality typically includes over-theair distribution of applications, data and configuration settings for all types of mobile devices, Mobile Application Management (MAM) App Centric strategy is around for developing, securing, deploying, configuring, updating and removing business applications from mobile devices centrally. Application Wrapping: MAM functionality includes wrapping of the enterprise application as per the business policies. Key Aspect MDM only protects and secures the mobile devices. It does not control the applications,data or transactions. BYOD Success = Mastering BYOD Control Points Key Aspect MAM provides application level security to maintain both personal and corporate data with different security levels. Devices Apps Data 17

18 Mobile Device Management (MDM) Enable Activate enterprise access, apps and data easily and automatically ios, Win Mobile, BB, Symbian Secure Protect enterprise data and infrastructure from attack and theft Prevent JB, ensure passcodes. Manage Control inventory and configuration with massive scalability Tracking the device 18

19 Mobile Device Management (MDM) features Authentication and Access Control Integration with LDAP 2 factor authentication Single sign on Digital certification for mobile device/smartphone authentication (e.g. Managed PKI solution Information Protection DLP for Mobile devices Antivirus /Malware protection App Center / Cloud for application data management Device Control and Management Managed Device Inventory Remote assistance and wipe out Compliance /policy enforcement(e.g. certificate distribution, password management, camera permission, encryption management) Device Security - Anti malware /Live updates, SMS anti-spam, location update of devices, Application control. App Distribution and Collaboration Application provisioning as per the business requirements. No Protection of the data. 19

20 Mobile Application Management (MAM) Corporate Computing in Transition By 2014, 90% of organizations will support corporate applications on personal devices By 2013, 80% of businesses will support a workforce using tablets Developer Creates apps either native or web Readies it for publishing Notifies Admin via App center Source: Gartner IT Administrator Role based permissions and reporting Enforcement of corporate policies with respect to apps or content Distributed through App store/cloud Employee Receives notification that app or doc is available. Downloads and runs the secured app or accesses the secured doc Has familiar app store experience 20

21 Mobile Application Management (MAM) features Policy Management User authentication and integration with AD/LDAP Encryption Access control on Jail broken devices Restriction to network connections Document sharing Offline access Additional content policies such as versioning and expiry Secure Browser Web apps are tied to specific set of authorized sites (e.g. intranet sites) Inter application data transfer protection Restricting copy paste / downloading content Multiple deployment options Cloud based On-premise : Private cloud or Virtual appliance Reporting Standard reporting on application usage Downloads Data access requests Users Connectivity Real -time metrics Supports Diverse Content types PDFs Videos Forums epub documents 21
