unmanaged but secured – how mobile application management support your enterprise

while ios and android offer more and more deep api to securely managed a mobile device and integrate into enterprise – apple utilize restrictions to natively separate managed from unmanaged content – android buildin work container on every device to secure enterprise data – both offer enrollment program to easiely intergrate the devices to management system

but there a argument to not rely on device management api – ios lack unfinished restriction of unmanaged/managed data, it is possible to bypass limitation under certain conditions – android depricated existing device admin feature in favor of android enterprise technology, but new container ui/ux isn’t consitant between different os releases and lack of some existing features, e.g. private/business calender overlay

privacy is a main point to offer a byod solution for your employees, ios managed devices could report your installed app and fully wipe even your private data (until user-enrollment was released), android enterprise addressed this from the very first, apple introduced user-erollment to address privacy concerns for byod deployments

usablity is the other big point to address for your users – while apple provide the ability to use business data within ios native applications, android lack of a consistant look and feel between os releases and different management api, batch icons differ at different releases and espesially samsung devices – to ease support provide the same email app across both mobile os

mobile application management also named non-MDM managed your data within an app or a entire framework, the app is’t capable to control your device, e.g. to enforce device pin or encryption – major mdm vendor like airwatch, mobileiron, blackberry formerly good and citrix provide a framework to secure your data over serveral productivity apps, without the need to rely on device api

blackberry_uem-logos

microsoft offer with it’s office 365 apps the capability to secure business data with app protection policies without the need to enroll your device to a unified endpoint management, 3rd party mdm could optinally integrate these features with graph api

Conceptual image that shows company data being protected by policies

when it comes to enterpise integration with full device vpn support, certificate authentication or kiosk (single use) devices there is no way around a uem solution

don’t be a fool, select your prefered solution, based on the requirement for each usecase

new forms of malware via calendar invite even more annoying

more often noticed and actually effected by myself – google calenar display per default new invites from inbox, usually displayed in calendar for easy scheduleing or to block the timeslot – so attacker can target your gmail account to push notification directly to your mobile device when the fake calendar entry occurs

to get rid of this spam, it’s not enough to delete each calendar entry, because a new invite immediately popup’s in your calendar – your have to disable the feature “automatically add invitations” in google calendar event settings

further … a vulnerability in WIB sim-browser can let attackers globally take control of hundreds of millions of the victim mobile phones worldwide to make a phone call, send SMS to any phone numbers, send victim’s location, launch WAP browser, etc. – read more

… if you want to test or troubleshoot your mobile webpage or browser app it’s quite tricky from desktop – mobile webapplication deliver content based on the browsers user agent – there are severals browser plugins to switch the agent – but all major browser offer a build in feature to change the behaviour

google chrome

in settings > more tools > developer tools (Crtl + Shift + I) below network conditions your able to switch user agent – e.g. search at google to display

microsoft edge and internet explorer

F12 developer tools (press F12) > Emulation opens an onboard user agent switcher

mozilla firefox

webpage is loaded in same way an iPad would do – type about:config in addressbar, search for useragent and create a new entry

string: general.useragent.override

macOS safari

enable in settings > advanced the option show develop menu in menu bar

iOS devices

since iOS13 / iPadOS – safari browser of the apple tablet can switch between mobile and desktop presentation of a webpage, as shown in the video below

android devices

install e.g. Rocket Browser to test the behavoir of other user agents, in Settings > General Settings is it possible to change the user agent – developed android webapps can define an own user agent with java code webview.getSettings().setUserAgentString(MyString);
