NSFileProtectionNone is easiest to use but most vulnerable for security risk. We should always use NSFileProtectionCompleteUnlessOpen or NSFileProtectionCompleteUntilFirstUserAuthentication as default file protection level option. NSUserDefaults provides us a way to save small bits of information that needs to be persisted between app launches and device restarts. All the info saved as part of UserDefaults is saved as plain text in plist which is not encrypted and can be read by anyone who has access to the device. App/Client bundles the SSL certificate of the designated server, so that it can match the SSL cert received while connecting to server and local cert.

Developers use debug message as a great way to log the behavior of the app. When the app is under development we tend to log some information to help the developers build the features. But, if it becomes accessible to a hacker it can expose confidential info and internal working of the app. In order to make sure we don’t log the message on the version of the app that we submit to store we just to put a basic check to log only while app is in Debug mode by simply doing the following. Any secret info shouldn’t be part of repo/code base, instead we should use configuration file or environment variables that are injected while building apps. A good option is Xcode Config files which maintains info pertaining to a specific target.

Moreover, for secure communication between APIs, mobile app developers can use various authentications like OAuth and OAuth2. According to Statista, mobile apps were downloaded by users more than 205 billion times in 2018 alone. So it’s no surprise that mobile apps are being targeted more and more by cybercriminals. Although mobile app security best practices releasing an app can be hugely beneficial to your customers, you must take the necessary security precautions. After all, your app won’t be so beneficial if it results in the theft of user data. Keep mobile application security as a top priority throughout the development of your app to mitigate any potential security risks.

That’s right, this tutorial will purposely omit some specific information you would use to attack a real app. There won’t be too much code here, but you should have a good grasp of general Objective-C and Cocoa concepts. NSExceptionDomains exception and whether any domains are listed there. We’ve encountered a number of cases where developers have opted out of ATS globally, but then opted in only for certain domains by listing an exception domain. A better approach is to enable ATS globally, and only opt out for certain domains if absolutely necessary . You receive a proposal with estimated effort, project timeline and recommended team structure. We delve into your business needs and our expert team drafts the optimal solution for your project.


If the server receives an unknown certificate (such as with Man-in-the-Middle attacks) the connection is immediately terminated. Even with the use of a HTTPS connection, third parties are still able to view data when communicating with the server.

In the time when Google Cloud Messaging or GCM did not exist, SMS was used in order to push data from servers to apps but today, GCM is used largely. But if you still have not made the switch from SMS to GCM, you must. On top of it, SMS can be accessed and read by any other app on the user’s device. GCM communications are authenticated by registration tokens which are regularly refreshed on the client-side and they are authenticated using a unique API key on the server-side. • Due to offline usage requirements, mobile apps may be required to perform local authentication or authorization checks within the mobile app’s code.

Mobile Application Security Assessment

71% of fraud transactions came from mobile apps and mobile browsers in the second quarter of 2018 compared to 29% on the web, up 16% year over year. You don’t need a multi-million dollar budget or 24/7 security team to protect your website and business against the latest cybersecurity threats. Savvy Security’s mission is to provide practical, proven advice to help you keep hackers out of your business. Whether it is a communication between applications, back-end server or web services, it is important to encrypt. So, in case your application supports any kind of private data, it should be end-to-end encrypted. Timely installing software updates & patches are a very effective way to maintain software security. One shouldn’t waste time trying to solve problems that can already be rectified through updates and patches.

Then monitor your app after its launch so that you can identify and address any potential vulnerabilities or issues. Encryption of data at transit and rest is key to maintaining web application security best practices. Basic encryption by a web development company usually includes the use of SSL with a current certificate. Saving sensitive data of the users, such as their IDs or passwords in plain text can be dangerous as it could open room for MITM (man-in-the-middle) attacks and expose the data. Therefore, web application development must be done ensuring that the strongest encryption algorithms are always used. This blog outlines some of the crucial mobile app security measures that every mobile application development company must employ while they architecture their apps.

Measure the potential users it will give you and see if it is worth the effort and investment. Generally, the dilemma an iOS developer Error correction code face is how to balance building an iOS app that follows the latest trends and has backward compatibility for the increased user base.

Here the red teaming refers to hiring an external team that constantly tries to attack & breach your security, while the in-house blue team is responsible for fighting it. A good red team over the course understands how to push the developers to be prepared at all times. For instance, consider an application that uses token-based authentication. The application sends user credentials — using encryption — but once the token is received, the application sends the token in plaintext during subsequent API calls. Anyone on the network can intercept these requests, read the plaintext token and make malicious API calls with a stolen user token. The mobile app security best practice to prevent these vulnerabilities is to always use SSL/TLS with any sensitive application traffic.

Secure The Data

For each keychain item, developers can define exclusive authentication policies for secure access. HTTPS connections are validated by default and so, the system checks the server certification and domain validity. To prevent these attacks, iOS apps can integrate additional trust verification of server certificates using certificate pinning. So, while the application gets installed it should ask users permission to access data such as contacts, hardware or files. Whenever you develop an application get those necessary requisites and never ask for sensitive information which your user may not be comfortable in providing you. The shift-left approach, also known as the DevSecOps aims to detect security holes from the very beginning & prevents as well as resolves security issues as quickly as they arise. It enables the web application development team to spot and resolve security problems at all stages.

Veracode’s comprehensive network of world-class partners helps customers confidently, and securely, develop software and accelerate their business.

The communications that take place between the app and user outside the mobile phone device happen via servers. And such servers are primary targets of hackers throughout the world. The main reason behind the vulnerability of a server is because sometimes developers overlook the necessary server-side security into account. The threats that present themselves in the app development world although are malicious, can be solved with simple steps to securing a mobile application. Let us take a look at what are the major mobile app security issues. Delivering a user-friendly and security-compliant app will not only ensure the security of enterprise and consumer data but also enhance brand identity. When it comes to accessing confidential data, the mobile apps are designed in a way that the unstructured data is stored in the local file system and/or database within the device storage.

App developers can leverage the following best practices for designing apps that ensure complete data security against thefts and leaks. Although we all are aware of app security breaches and best practices to be followed, still IT departments ask to focus on below mention key areas for ensuring mobile app security. Mobile application developmentplatforms have helped in simplifying the entire process of application creation. Using advanced methods, intuitive platforms, simpler plugins, anyone can easily create his/her own mobile application. But, developing a useful and engaging mobile application takes a great toil and effort. SAST or Static application security testing is a scanning method based around the source code.

Most of us are guilty of using the same insecure password across multiple accounts. Even if a user’s password was compromised through a breach at a different company, hackers often test passwords on other apps, which can lead to an attack on your company. When the operating system has two or more applications to choose from when opening a link, Android will show the user a modal and ask them to choose which application to use to open the link. On iOS however, the operating system will make the choice for you, so the user will be blissfully unaware.

We are doing what we can in the industry and the first step is to increase awareness. One of the many advantages of iOS app development that appeals to aspiring mobile app developers is the extensive collection of varied developer resources available to use.

Hence, it is ideal to first discuss and allot a specific budget for iOS app design processes. It helps designers understand their limitations and make the best use of the allotted budget for an efficient app design process rather than being frustrated later on. They offer some valuable resources that enhance your iOS app functionalities but most of them are vulnerable and loosely secured. One of the iOS app development best practices is to keep these third-party integrations updated to the latest stable version available at all times. Don’t disable ATS even if the integration persuades you to do so.
