Securing Mobile Applications - Subho Halder Appfest  5 Why Mobile Security Is Important ?  More data could be more danger with mobile devices ì ì ì ì ì ì Data Breaches With more data accessible to applications, security becomes more paramount. Mobile Malwares Gone are the days of computer malware, mobile malware are now growing more sophisticated with access to more data Businesses worry about smartphone risks While the threat is universal, being protected doesn’t have to be difficult. If anything, it is becoming increasingly important. Cyberattacks on mobiles increasing Cyberattacks on mobile devices, especially smartphones, have become all too common. And over the last year alone, we’ve seen cybercriminals deploy all sorts of effective strategies. Privacy Leakages Privacy has also been called into question, as so many of these mobile apps collect huge quantities of data and store them. 

Securing Mobile Applications - Subho Halder Appfest  6 Hackers vs Developers  Fighting the good fight Developers are one who creates a system and wants the system to run as expected Developers almost always doesn’t think about attacking the app & wants to exploit the app or the data Developers are busy creating new features and functionalities, often neglecting security Hackers are one who doesn’t play by your rules Hackers need only one opening, one weakness. Hackers almost always wins :) They don’t care about functionalities, but are looking for that one bug HACKERS ARE NECESSARY AND NOT EVIL :) hackers and developers represent duality

Securing Mobile Applications - Subho Halder Appfest  8 Top 10 Mobile Security List  The goal of this is to raise awareness about application security by identifying some of the most critical risks facing organizations. Poor Authorization and Authentication Poor or missing authentication schemes allow an adversary to anonymously execute functionality within the mobile app or backend server used by the mobile app. ç Unintended Data Leakage Unintended data leakage occurs when a developer inadvertently places sensitive information or data in a location on the mobile device that is easily accessible by other apps on the device. ‚ Insufficient Transport Layer Protection If the application is coded poorly, threat agents can use techniques to view this sensitive data. Unfortunately, mobile applications frequently do not protect network traffic 0 Insecure Data Storage Many developers assume that storing data on client-side will restrict other users from having access to this data. : Weak Server Side Controls Most security experts might argue that server-side security falls outside of the area of mobile application security threats. Till last year, it was the second most important mobile security threat. Z 05 04 03 02 80% 43% 01 64% 72% 19% Source: https://blog.appknox.com/category/owasp-top-10-mobile/

Improper Session Handling Broken Cryptography or insecure usage of cryptography is mostly common in mobile apps that leverage encryption. Broken Cryptography Developers generally use hidden fields and values or any hidden functionality to distinguish higher level users from lower level users. Security Decisions Via Untrusted Inputs A lack of binary protections within a mobile app exposes the application and it’s owner to a large variety of technical and business risks if the underlying application is insecure or exposes sensitive intellectual property. Lack of Binary Protections

Firstly, occurrences of ransomware, malware, rotten apps on the iTunes store, and social engineering have been coming into the news far more often in recent times. The iOS Device Google’s Android platform has become a larger target for mobile malware writers than Apple iOS. This could be a result of Android’s popularity—with more than 1 million activations per day, Android smartphones command a 59% market share worldwide. The Android Device
