Running what applications? Processing, storing, transmitting: what data?Conduct a treat / risk assessmentDraft Asset RegisterDraft Risk RegisterWhats the threat?Quantify If the definition of a threat is the "expressed potential" for a "harmful event" to happen to your business."What mobile device events would be harmful to your business? What Applies?Step 2Draft policies Device ownershipDevice liabilityAcceptable devicesAcceptable useAcceptable applicationsMinimum device security requirementsWhere to report lost/stolen devicesSecurity Awareness Program ConsiderMandating use of PINs to access devicesMandating use of complex passwords to access applicationsSet max number of password failures Set max days of non-use lock outSpecify password change intervalPrevent password reuse via password historySet screen-lockStep 3ConfigurationFirewallAnti-virus (Malware, Trojans, Spyware)O/S UpdatesHardeningBack end support serversVPN dual authenticationAdding or removing root certsConfiguring WiFi including trusted SSIDs, passwords, etc.Configuring VPN settings and usageBlocking installation of additional apps from the AppStoreBlocking GeoLocationBlocking use of the iPhones cameraBlocking screen capturesBlocking use of the iTunes Music StoreBlocking use of YouTubeBlocking explicit contentConsider*Step 4EncryptionDataDiskDocument, File & FolderLaptopPort & Device ControlsRemovable Media & DeviceEmailLayers DataDiskDocumentFile & FolderClient SideLaptopPort & Device ControlsRemovable Media & DeviceEmail Encryption Options Data Base Encryption: Applicationlevel encryption of data at rest in data base. Disk Encryption: Disk-level encryption for all data on the logic or physical drive (user files, swap files, system files, page file).
