Mobile Security – The impending apocalypse… or maybe not ISF Summer Chapter

Before we begin…

Hopefully not a lesson in sucking eggs

Agenda

•What the press would have you believe

•The reality

Before we begin… Who is this guy?

• Information Cyber Security for > 15 years • Consultancy – 1997 – 2005 • Research – 2005 – 2011

• Symantec / BlackBerry • Research / Consultancy – 2012

• Recx / NCC Group

What you are led to believe

•Mobile is as insecure the desktop •BYOD is insecure •Malware is rampant •Mobile security needs augmenting

Motivations

• .… something to sell

•…. exposure

Mobile is as insecure as the desktop

• Incentivised •Defence in depth •App stores •Ubiquitous sandboxes •Security policy APIs •Vendors adopting SDLs

BYOD is insecure

•BYOD is CHALLENGING

•Extending your security perimeter •Loosening your control (potentially) •Mixed domain devices •Policies

Malware is rampant

•Malware is present NOT rampant

•Trojans (re-packaged apps) •Trojans (unique appealing apps)

•App store revocation •People using third party app stores

Malware is rampant

Mobile security needs augmenting

•Platforms have rich security stories •Samsung KNOX •BlackBerry Balance •MDM APIs / Policies ..

•Some augmentation may be needed

•on iOS •On device AV is not one of them

But it is no utopia

SDLs cost

•Vendors don’t have • limitless funds • limitless people • limitless time

•Market driven by features •not secure code

•Skills in short demand •Not evenly deployed

Vulnerability v patching frequency

•No monthly patch Tuesday •Carrier certification

•desire • capacity

•Vendors •desire • capacity

Vulnerability v patching frequency

•Handset cycle 12 to 36 months •HTC 10 Android models •ZTE 18 Android models •Samsung 12 Android models •Apple 1 iPhone model •BlackBerry 3 BB10 models

•Sustainment costs huge..

Vulnerabilities can be exploited

But… criminals are lazy …

But… there are motivated enablers..

Devices are complex

•Peripherals •Radio •OS •Apps = a large and complex attack surface

Rapid change

Use cases are different

•Physical interaction •Usage patterns

Mobile security – the future
