3. BLACKBERRY ENTERPRISE SERVICE HELPS MANAGE AND PROTECT BLACKBERRY, IOS, AND ANDROID DEVICES.
UNIFIED COMMUNICATION AND COLLABORATION SOFTWARE
DESIGNED TO HELP PROTECT DATA THAT IS IN TRANSIT AT ALL POINTS AS WELL IS IN MEMORY AND STORAGE
ENHANCED BY A CONTROL OF THE BEHAVIOR OF THE DEVICE
PROTECTION OF APPLICATION DATA USING SANDBOXING
MANAGEMENT OF PERMISSIONS TO ACCESS CAPABILITIES
BB EVALUATES EVERY REQUEST THAT APP MAKES –BUT LEAD AWAY FROM ANY DETAILS AND APIs

CONTROLLED 7 GROUPS ONLY by BlackBerrythat‘s NOT ENOUGH TO MANAGE ALL APIs

8. THERE 55 GROUPS CONTROLLED IN ALL
EACH GROUP CONTAINSFROM 10 TO 30 UNITSARE CONTROLLED TOO
EACH UNIT IS UNDER A LOT OF FLEXIBLE PARAMs INSTEADOF A WAY ‘DISABLE/ENABLED & HIDE/UNHIDE’
EACH EVENT IS
CONTROLLED BY CERTAIN PERMISSION
ALLOWED TO CONTROL BY SIMILAR PERMISSIONS TO BE MORE FLEXIBLE
DESCRIBED 360 PAGES IN ALL THAT IN FOUR TIME MORE THAN OTHER DOCUMENTS
EACH UNIT CAN’T CONTROL ACTIVITY UNDER ITSELF
‘CREATE, READ, WRITE/SAVE, SEND, DELETE’ ACTIONS IN REGARDS TO MESSAGES LEAD TO SPOOFING
BY REQUESTING A ‘MESSAGE’ PERMISSION ONLY
SOME PERMISSIONS AREN’T REQUIRED (TO DELETE ANY OTHER APP)
SOME PERMISSIONS ARE RELATED TO APP, WHICH 3

THAT PLUGIN
BLACKBERRY CAPABILITES –BLACKBERRY (OLD)
INCREDIBLE AMOUNT OF GROUPS, UNITS AND PERMISSIONS ARE CONTROLELD BY MDM AND DEVICE

9. OLD BB: MERGINGPERMISSION UNITS AND GROUPS
‘SCREEN CAPTURE, CAMERA, VIDEO PERMISSIONS’ SEPARATED (PREVIOUS BB)

WHILE THE ON TOP || JUST MINIMIZE OR CLOSE IT TO GET FULL ACCESS
EVERY USER CASE MUST MINIMIZE APP TO PASTE A PASSWORD
ISSUES : USELESS SOLUTIONS -II
USERFULL IDEAS AT FIRST GLANCEBUT INSTEAD MAKE NO SENSE

12. INITIALLY BASED ON AUTHORIZED API COVERED
ALL PHYSICAL & NAVIGATION BUTTONS

SIMULATOR
EXAMING THE TRAFFIC, BEHAVIOUR
JUST SHOULD CHECK API “IS SIMULATOR” ONLY
SMS MANAGEMENT VIA “QUITE” SECRET SMS
PASSWORDIS 4–16 DIGITS,AND MODIFIED IN REAL-TIME
SMSIS A HALF A HASH VALUE OF GOST R 34.11-94
IMPLEMENTATION USES TEST CRYPTO VALUES AND NO SALT
TABLES (VALUEHASH) ARE EASY BUILT
OUTCOMING SMS CAN BE SPOOFED WITHOUT ANY
NOTIFICATION, BECAUSE KMS DELETE THE SENT MESSAGES
OUTCOMING SMS BLOCK/WIPE THE SAME/ANOTHERDEVICE

CONCLUSION -I
PRIVILEGED GENERAL PERMISSIONSOWN APPs, NATIVE & 3
RD
PARTY APPs FEATURES

17. SIMPLIFICATIONAND REDUCINGSECURITY CONTROLS
MANY GENERALPERMISSIONS AND COMBINEDINTO EACH OTHER
NOLOGs ACTIVITY FOR SUB-PERMISSIONS TO PROVE THE TRANSPARENCY
ANY SECURITY VULNERABILITY ARE ONLY FIXEDBY ENTIRELY NEWAND DIFFERENT OS/ KERNEL
A FEW PERMISSIONs ARE CLOSED TO THE USER ACTIONS
THE SANDBOX PROTECT ONLY APPLICATION DATA
USERS HAVE TO STORE THEIR DATA INTO SHARED FOLDERS OR EXTERNAL STORAGE
APPLICATIONS CONTINUE STORE DATA IN PUBLIC FOLDERs BECAUSE GOVERNED BY CHANCE OF AVAILABILITY
MITM / INTERCEPTION ACTIONS ARE OFTEN SILENTLY
THE NATIVE SPOOFING AND INTERCEPTION FEATURES
BLACKBERRY ENTERPRISE SOLUTION / BLACKBERRY MOBILE FUSION IS NOT EFFECTIVE MUCH
THE BEST SECURITY (PERMISSIONS) RULED BY AMAZON WEB SERVICES
PERMISSIONS SHOULD RELY ON THE DIFFERENT USEFUL CASES SET INSTEAD OF SPECIFIC PERMISSION LIST
CONCLUSION -II
THE VENDOR SECURITY VISIONHAS NOTHING WITH REALITYAGGRAVATED BY SIMPLICITY
