Top 1. 0 mobile controls and design principles. Identify and protect sensitive data on the mobile device. Risks Unsafe sensitive data storage, attacks on decommissioned phones unintentional disclosure Mobile devices being mobile have a higher risk of loss or theft. Adequate protection should be built in to minimize the loss of sensitive data on the device. In the design phase, classify data storage according to sensitivity and apply controls accordingly e. Process, store and use data according to its classification. Validate the security of API calls applied to sensitive data. Store sensitive data on the server instead of the client end device. This is based on the assumption that secure network connectivity is sufficiently available and that protection mechanisms available to server side storage are superior.

Many thanks to the members of the Switchyard Park Master Plan Project Management Team, Technical Review Committee, and Steering Committee who generously shared their. The relative security of client vs server side security also needs to be assessed on a case by case basis see ENISA cloud risk assessment 3 or the OWASP Cloud top 1. When storing data on the device, use a file encryption API provided by the OS or other trusted source. Some platforms provide file encryption APIs which use a secret key protected by the device unlock code and deleteable on remote kill. If this is available, it should be used as it increases the security of the encryption without creating extra burden on the end user. It also makes stored data safer in the case of loss or theft. Multimaster replication is a method of database replication which allows data to be stored by a group of computers, and updated by any member of the group. Support site offering resources for Citrix Presentation Server, VDI, VMWare, Xen, Microsoft Terminal Services, SoftGrid and others. However, it should be born in mind that even when protected by the device unlock key, if data is stored on the device, its security is dependent on the security of the device unlock code if remote deletion of the key is for any reason not possible. Do not storecache sensitive data including keys unless they are encrypted and if possible stored in a tamper proof area see control 2. Consider restricting access to sensitive data based on contextual information such as location e. GPS data shows phone is outside Europe, car key not usable unless within 1. Do not store historical GPStracking or other sensitive information on the device beyond the period required by the application see controls 1. Assume that shared storage is untrusted information may easily leak in unexpected ways through any shared storage. Things You Should Have. Youll need a few supplies along with these rules to play the game. Heres a list of mandatory items, as well as some recommended ones. Mobile Master 7.6 License -Mahiy-' title='Mobile Master 7.6 License -Mahiy-' />In particular. Be aware of caches and temporary storage as a possible leakage channel, when shared with other apps. Be aware of public shared storage such as address book, media gallery and audio files as a possible leakage channel. For example storing images with location metadata in the media gallery allows that information to be shared in unintended ways. Do not store tempcached data in a world readable directory. For sensitive personal data, deletion should be scheduled according to a maximum retention period, to prevent e. There is currently no standard secure deletion procedure for flash memory unless wiping the entire mediumcard. Therefore data encryption and secure key management are especially important. Consider the security of the whole data lifecycle in writing your application collection over the wire, temporary storage, caching, backup, deletion etc1. Apply the principle of minimal disclosure only collect and disclose data which is required for business use of the application. Identify in the design phase what data is needed, its sensitivity and whether it is appropriate to collect, store and use each data type. Use non persistent identifiers which are not shared with other apps wherever possible e. ID number as an identifier unless there is a good reason to do so use a randomly generated number see 4. Apply the same data minimization principles to app sessions as to http sessionscookies etc. Applications on managed devices should make use of remote wipe and kill switch APIs to remove sensitive information from the device in the event of theft or loss. A kill switch is the term used for an OS level or purpose built means of remotely removing applications andor data. Application developers may want to incorporate an application specific data kill switch into their products, to allow the per app deletion of their applications sensitive data when needed strong authentication is required to protect misuse of such a feature. Handle password credentials securely on the device. Risks Spyware, surveillance, financial malware. A users credentials, if stolen, not only provide unauthorized access to the mobile backend service, they also potentially compromise many other services and accounts used by the user. The risk is increased by the widespread of reuse of passwords across different services. Instead of passwords consider using longer term authorization tokens that can be securely stored on the device as per the OAuth model. Encrypt the tokens in transit using SSLTLS. Tokens can be issued by the backend service after verifyingSmartphones secure development guidelines for app developers the user credentials initially. Corel Draw X7 Keygen 64 Bit'>Corel Draw X7 Keygen 64 Bit. The tokens should be time bounded to the specific service as well as revocable if possible server side, thereby minimizing the damage in loss scenarios. Use the latest versions of the authorization standards such as OAuth 2. Make sure that these tokens expire as frequently as practicable. In case passwords need to be stored on the device, leverage the encryption and key store mechanisms provided by the mobile OS to securely store passwords, password equivalents and authorization tokens. Never store passwords in clear text. Do not store passwords or long term session IDs without appropriate hashing or encryption. Some devices and add ons allow developers to use a Secure Element e. SD card module the number of devices offering this functionality is likely to increase. Navman Australia Maps on this page. Developers should make use of such capabilities to store keys, credentials and other sensitive data. The use of such secure elements gives a higher level of assurance with the standard encrypted SD card certified at FIPS 1. Level 3. Using the SD cards as a second factor of authentication though possible, isnt recommended, however, as it becomes a pseudo inseparable part of the device once inserted and secured. Provide the ability for the mobile user to change passwords on the device. Passwords and credentials should only be included as part of regular backups in encrypted or hashed form. Smartphones offer the possibility of using visual passwords which allow users to memorize passwords with higher entropy. These should only be used however, if sufficient entropy can be ensured. Swipe based visual passwords are vulnerable to smudge attacks using grease deposits on the touch screen to guess the password. Measures such as allowing repeated patterns should be introduced to foil smudge attacks. Check the entropy of all passwords, including visual ones see 4. Ensure passwords and keys are not visible in cache or logs.
