6. [ OPINIONS ]
Blackberry Windows iOS Android
 APPLE IS SO SERIOUS TO LET MALWARE BE SPREADED THROUGH THEIR MARKET, EXCEPT 
 Ch. MILLER CASE
 JAILBREAK,CYDIA,BLACK&OTHER MARKETS
 MICROSOFT (WINDOWS PHONE) HAS IMPLEMENTED THE SAME IDEA
 GOOGLE HAS A WEAK POLICY THAT WHY EVERYONE GOT MALWARE IN OFFICAL MARKET EVEN
 PLUS 3RD PARTY MARKET
 PLUS REPACKAGES
 BLACKBERRY IS THE SAFEST OS BECAUSE THAT'S ABOUT THE SIZE OF IT 

7. [ SECURITY ENVIRONMENT ]

 MDM HELPS TO PROTECT DATA AND MANAGE BLACKBERRY, iOS, WINDOWS, AND ANDROID DEVICES.
 MDM ENHANCED BY MANAGING THE BEHAVIOR OF THE DEVICE
 SECURE BOOTLOADER, SYSTEM SOFTWARE SECURITY (UPDATES),
 APPLICATION CODE SIGNING
 RUNTIME PROCESS SECURITY (SANDBOX, APIs)

𝛥 – set of OS permissions, 𝛢 – set of device permissions, 𝛣 – set
of MDM permissions, 𝛤 – set of missed permissions (lack of
controls), 𝜰 – set of rules are explicitly should be applied to gain
a compliance
𝚮 = 𝚬+ 𝚭, 𝚬 ⊃ 𝚨∪ 𝚩
𝛨 – set of APIs , 𝛦 – set of APIs that interact with sensitive data,
𝛧 – set of APIs that do not interact with sensitive data
To get a mobile security designed with full granularity the set 𝛤
should be empty set to get 𝚬 ⊇ 𝚨 ∪ 𝚩 instead of 𝚬 ⊃ 𝚨 ∪ 𝚩, so
the matter how is it closer to empty. On another hand it should
find out whether assumptions 𝚼 ⊆ 𝚩, 𝚼 ⊂ 𝐀 are true and if it is
possible to get ⊆ 𝐀.
The situationis very serious 
Set of permissions < Set of activities  efficiency is
 typical case < 100%,
 ability to control each API = 100%
 More than 1 permission per APIs >100%
