National Cyber Security Centre (NCSC)

App security development recommendations for Windows, Apple, and Android come at a period when data security appears very hard to ensure.
United Kingdom’s National Cyber Security Centre (NCSC) published a chain of new application security recommendations to be used by businesses or app companies which seek to deploy and develop applications on devices using delicate data.

Although the guidance which was published on 10th of May primarily targets London application developers and risks assessors, the paper presents useful insights for app companies running on Windows, Android, and Apple. Applications which handle, process, store or can access network with crucial information ought to be developed considering security as the most crucial aspect right from the start, and should be assessed and audited before use, the National Cyber Security Centre emphasized.

This report comes at a time when security is most crucial. We are at times when it is not uncommon to hear stories of poorly configured cloud buckets and applications which siphon Smartphones’ data. Clients’ email vulnerabilities for PGP encryption also cannot be ignored.

General Development Guidance Content.

The National Cyber Security Centre insists that application hardening, data handling, and third-party applications as the three most important aspects to be considered by the application platform or app companies in London. NCSC’s general guidance research has specifically made this clear. Secure data handling makes sure data is not leaked in at all by taking cryptography, storage APIs, secure data transmission, data access, session handling and data authorization into consideration. Hardening of application (application handling) involves the process of code development so that vulnerabilities like buffer overflow don’t occur; this is usually done through code obfuscation, stack protection, root detection, and jailbreak.

Android Guidance.

The second phase of the guidance is none other than the Android App Development Guidance that covers four parts exclusively for every Android application.

The first part covers secure Android app development that explains how the success of network protection and data hardening can be attained by implementing secure server-side controls and data storage.
Questions answered in depth include crucial factors such as IPC mechanisms, data transmission, client-side & server-side and binary protection. The last sections specify various recommendations, considerations and security requirements that point out various best technical practices for Android.

Apple Guidance.

The collection’s third part is Apple’s IOS App Development Guide. It goes through the same factors as those of Android like IOS’s secure development applications and questions for developers. However, Apple’s main focus is on different mechanisms like IOS Data Protection API, Automatic Reference Counting (ARC), App Transport Security (ATS) and IOS Keychain API because of its different functioning compared to Android.

Windows Guidance.

Windows Application Development Guidance is the very last report. Similarly, it includes development advice just like Apple IOS and Android which consists of questions for developers, secure deployment, and secure development. However, its report puts more focus on comparable features to Android for it discusses network protection, data storage, data hardening, client-side and server-side controls and binary protection with the UWP- Universal Windows Platform.

In general, the Generic App Development Guide by the National Cyber Security Centre will provide information security professionals and developers with key information which they probably never considered before. The information will ultimately improve deployment, application security development, and use.
