Mobile device security, with ever-advancing mobile technology, has become a critical issue that must be considered and understood by every major organization. Sensitive data stored on a computer may be lost or compromised, which can lead to a breach of data, violations of compliance, and costly and/or embarrassing public disclosures.
Large organizations understand risks and vulnerabilities in mobile devices and perceive that they have proper security safety. Corporations are now using mobile apps to deliver appropriate, sensitive information to their staff, partners, or clients.
The efficiency of mobile devices comes at a price that increases the risk of security. Mobile apps provide another avenue into network services, enabling malicious code to be propagated by terrorists, fraudsters, and hackers.
Best mobile application security practices for a development team:
Encrypt the Data at All Levels
Although protection at the system level is important, it is typically best practice not to rely solely on security at the device level. Mobile enterprise data must be encrypted at all levels for optimum security, including at the file system, programmer, database access, and computer levels.
Use Strong Encryption
If the data is at rest on the computer or in transit between the device and servers behind the firewall, all application data should be encrypted with safe encryption. It is necessary to protect all data from end-to-end.
Isolate Application Information
All application information accessed from mobile devices should be entirely separated from the data of the user. Isolating mobile app data involves building a layer of security around enterprise-deployed apps that isolate corporate data safely from private information and user applications of an employee.
Usually, a solution that improves employee satisfaction and efficiency while ensuring compliance is the separation of business applications and data. More significantly, the container-based approach ensures that protection at all stages of transmission is uncompromising, reducing the possibility of loss of corporate data.

Enforce User-Level Application Security Policies
App developers should ensure that IT security administrators can identify and implement user-level device policies. It helps to ensure that access to corporate applications and data is secured by allowing remote wiping of application data after a failed number of incorrect passwords, deactivating sequence numbers in passwords, and having special characters in passwords.

Ensure Secure Network Access
Projects can eliminate the need for inbound ports to be opened and the network explored. Only encrypted packets, authenticating applications, and granting access only to those given to particular servers and services should be served by the protected mobile device solution, thus preventing rogue attacks.
Secure the Platform
Strictly managed platform protection should be in place, which includes detecting jailbroken phones and preventing access to other services when necessary. Protection of IOS Application Part 24 – Detection and Evasion of Jailbreak.
Strong authentication of the application will ensure that users are required to enter a protected password before beginning the application in question. Multi-step authentication for user ID plus password and stable ID/SMS on secure XML-based Web services is suggested. Another advice is to verify the location of the user during authentication by using GPS.
Enable approved users to only access the business features that they are required to access. The application will check with the back-end services after a user has authenticated, to decide if the user has the necessary access to the application data (i.e., whether the user is mobile-enabled or not). Based on user permissions/access privileges, the client shows a protected navigation menu. Until initiating business operations, permissions/access privileges are checked against the context of each request.
Minimize the application’s package of any plain-text tools. This keeps malicious attackers from gathering information into the internal application. It is important to strip the symbol table, leave only unresolved symbols and force the attacker to traverse the data in the runtime code, decode binary code, or map the application symbol to class names, methods, and function names using more sophisticated debugging tactics.
Root Certificate Check
The primary objective is to protect the client and the back end server communications. A client-side certificate review should be produced to ensure it is accepted by the company.
The mobile app should prevent it from being attached by the debugger (e.g., to read sensitive data from memory in use by another running application).
The application must check that there has been no manipulation. For instance, debug flags can be tested to decide whether the app is being debugged.
In the case of a security breach, older versions of software must be able to block unique older versions of the application on the back-end server.
It is important to log and send back security events that occur within the mobile app to the server.
The mobile application can prevent its traffic from being diverted to a malicious server by ensuring that DNS host name searches are resolved to a white-listed IP.
Like property archives, sensitive data must be shielded. Tools will transparently encrypt asset data, so hackers won’t be able to escape with them.
Only until required should critical data be stored in memory (and not on the hard drive). Sensitive data on the file system cannot be stored by the programmer. There should be no leaking of sensitive information by logs and error messages. When the programmer is running in the background, the application cache manager needs to clear details.
Secure Data Cleanup
When a log-off is enabled, all protected items in the system (data requests, account information, user-related data, etc.) must be safely deleted. Also, when a log-off is activated, protected objects and data structures should be cleaned. In a situation where tampering with the application is observed, the application should be forced to close.
Local Data Transfer Prevention
The software should restrict the transfer of any data locally outside the app (e.g., copying it or sending it to an unauthorized external use). When the app runs in the background, the data from the clipboard should be deleted so that it cannot be transferred outside of the application. For sensitive fields, disable long button.
All data over the network is encrypted. Using the HTTPS protocol will be better for connecting to back end applications. To prevent apps from talking to other domains not listed on the white list, an additional white list of IP addresses and domain names should be maintained on the client side.
OS Security Check
Identify whether the application is running on a computer infected with jailbroken/rooted/malware. Security review gives a ranking on OS security changes and identification of malware. The application may decide to close the app on the basis of this score, or the score can be forwarded to the back-end systems for further investigations/actions over a secured channel.
In a case where the computer is rooted or jailbroken, tested applications must prevent hackers from accessing the app.
User-level mobile device security practices:
Make sure you check the privacy choices prior to downloading a new mobile app. In addition, review the permissions regularly to ensure they have not modified.
Always have your data backed up. For mobile devices, you also automatically back up large quantities of material, such as images or messages. Backups, however, often store configurations, programmers, and other information about the system, making it much easier to recover from a failed device or migration.
Enable your apps to update automatically, so that the new version of the operating system and apps are still running. Hackers are still searching for software vulnerabilities, and new fixes and patches are continually released by developers to repair them. It will make it much harder to reach smartphones by constantly running the new operating system and mobile applications.
Often download apps from trusted sources that you need and only. Although apps from other websites can be downloaded, they are not vetted and are much more susceptible to infection with malicious code.
Also, check to make sure it has plenty of good feedback before installing an app and is actively updated by the developer. Try to avoid brand new applications, apps that have few reviews online. There can be a significant threat from seldom modified applications. Less is more: remove it from your phone if you don’t need an app, which can eliminate a few risks as well.
Built-in Safeguards to Prevent Unauthorized Access
There is a username, password, and six-digit PIN for the mobile application (generated through Google Authenticator, Yubico, etc.) which is required before accessing the data in the app. A foreign person might also need to be remotely locked out so that he/she may not (or no longer) access the data stored in the app or prevent data from being downloaded/uploaded from/to the database.
The above approaches can serve as a form of mobile device security checklist, and we hope they’ve helped you, whether you’re a user, an app developer, or a security specialist.
