    The emergence of a broad variety of novel technologies has given rise to valid concerns about security. To state the obvious: Maintaining security is currently among the biggest concerns in the global IT market. Everyone, from users to companies, to lawmakers are becoming increasingly serious about privacy as well as data security. Moreover, considering the prevalence of smartphones, and by extension apps, it only makes sense that security is also a top concern when it comes to the development of mobile applications.

     

    Interestingly, iOS has mastered the security in this context, thanks to its closed system as well as the restrictions implemented by its parent company -- Apple. Though deemed among the most secure mobile operating systems, security in the context of iOS apps can be a broad topic of discussion owing to the variety of aspects it encompasses. Case in point: Using an app typically requires the user to enter personal data. Unless such data gets stored securely, there will always be a risk of users' data being leaked owing to any number of unforeseen events. Then there are also eventualities such as the humans in the middle attacks where HTTP(s) requests are intercepted and receive doctored responses. Alternatively, reverse engineering, wherein the attacker acquires URL addresses, identifiers, keys used in the app or steal the business' intellectual property - especially if the company's mobile app uses advanced algorithms.

     

    However, there are ways to build secure apps that are resilient to threats. Here are some ideas:

     

    1. Safeguard user data: It is imperative to consider that you utilize the appropriate solutions for data storage and secure data as the users enter it. So, for keys, passwords, and logins, use Keychain. Moreover, for storing other user data, which may not be as crucial, one can make use of other solutions such as Realm Database and Core Data.
    2. Thwart reverse engineering: Though there aren't many ways to prevent reverse engineering, one can do their bit by developing the app in Swift and by using secure methods to store application keys for specific environments. One more option in this regard is to leverage confusion by creating traps and using deceptive method names to mislead attackers.
    3. Prevent man in the middle attacks: SSL pinning helps make sure that the app communicates solely with the appropriate server, which can prove to be quite a handy method to prevent man in the middle attacks. The SSL certificate is saved within the app bundle and used while delineating the pinned certificate upon session set up. We must note that the SSL pinning gets administered in different ways other than just storing the hash, public key, or certificate file within the application. And remember that if the app uses Alamofire library for network connections, the ServerTrustPolicyManager class will support all pinning choices.

     

    A smartphone app is typically a small part of a broader service and to make sure that the entire service remains fully protected, it is of vital importance to ensure that all components comply with informational security requirements. Though these pointers can not 100% guarantee protection from an attack, companies must engage a reliable company that provides custom iOS application development services to further alleviate the risk.
