With the advancement of technology, mobile devices have become more popular than desktop and laptop computers. Not only are they easy to carry, but they perform nearly similar functions as desktop computers do. Mobile devices are used for virtually every type of activity right from watching the news to interacting with friends online, sending emails, buying items online, and making bank transactions. Businesses can obtain helpful information from these apps, such as location, usage statistics, phone numbers, likes, dislikes, and other measurable metrics about users, which can help them make more informed decisions to improve the quality of their offerings. Mobile app security tools have become essential because the data in these devices could be harmful to users if they fall into the wrong hands. Secure mobile app development means securing applications against external threats like malware and cybercriminals with access to sensitive personal and financial information.
Security of mobile apps has become equally vital in today’s digital world. An attack on mobile apps can not only give hackers access to a user’s personal digital life, but it can also reveal banking information, personal information, and where they are located in real-time. Bank transactions are made possible by hacking credit and debit card numbers, especially when one-time passwords are not required. The negative outcomes of conducting security drills include customer loss due to the loss of customized data, as well as lawsuits from affected parties. The positive outcomes of conducting security drills are loyal customers and brand trust, however, the negatives are lawsuits from affected parties. These apps are not meant to serve as antiviruses or to transmit data securely over the internet.
Instead, they are meant to provide users with an optimal interface and superior functionality. As well, installing an antivirus program will help secure a network and prevent attacks on a device, but it will not help prevent problems caused by weak passwords or poorly designed software. Security experts have documented many of the notorious security mistakes under the aegis of The Open Web Application Security Project (OWASP) to serve as a guide for developers. This popular list offers comprehensive summaries of industry experts’ knowledge about mobile attack vectors currently being used and those that are being developed. Hackers try to exploit vulnerabilities in apps and devices using both manual and automated tools to exploit vulnerabilities. As described above, hackers get interested as their apps gain importance on users’ devices. There are many free application security testing tools available – usually referred to as AST tools – that can assist developers in reducing the chances of a security breach.
Application security testing tools that are free!
- Android debug bridge: Android Developers Box (ADB) is a package that allows developers to analyze Android applications. It consists of three components, namely a client, daemon, and server. The client and server can run on development machines or real mobile devices respectively. The server and daemon run on the development machine and manage communication on the client. The daemon runs as background processes on the device. In addition, ADB allows developers to test applications on either an emulator or a real device in real-time. Using ADB, developers can monitor events on the device instantly through USB, Wi-Fi, Bluetooth, and other networking protocols.
- Quick android review kit: A QARK analysis is a community-supported (licensed under Apache) tool for looking for security vulnerabilities in the code of an app. Developers can determine if their app contains vulnerabilities by using QARK analysis. When using this tool, users can run ADB commands on emulated or real devices without the necessity of rooting, as its purpose is to find vulnerabilities in apps when they are running in a supposedly secure environment. Besides Windows and Linux, this Python-based tool is also compatible with Mac OS X.
- Zed attack proxy: As part of the Open Web Application Security Project, it is owned and developed by The OWASP Foundation and licensed under Apache 2. It is based on the Paros Proxy, an open-source version of OWASP ZAP. A man-in-the-middle proxy, ZAP is used by penetration testers to listen to all requests made to a web app and to read all responses from it. ZAP is targeted at experienced security developers and is considered among the most popular apps when it comes to security testing. Through its automated scanners and other add-ons, security vulnerabilities can be scanned automatically and manually. Developers can launch known attacks against selected targets when using its active scanning feature.
- Drozer: The developer should test Drozer’s capabilities to ensure their Android app is secure enough when it communicates with other apps or the OS when passing through the Inter-Process Communication endpoints of Android. Drozer provides developers with Android public exploits that can be applied to devices they want to test. The program builds malicious files and web pages based on malicious malware that exploits known vulnerabilities. It is important for any developer who uses a vulnerable app for testing to be aware and fix security flaws immediately if the Drozer agent can install full agents.
- Devknox: Devknox has the benefit of allowing developers to check security lapses in their code as they write it, similar to the spell-check feature in a WYSIWYG editor. However, not all Android Studio plugins are available for free. XYSEC Labs has discontinued developing theirs, and they are preparing to release the code in an open-source format. Among other things, it suggests ways to improve code. In the same way that static code analyzers can identify security flaws in old code, this tool can uncover issues in the entire old code file. There are several factors that this tool checks against, such as verbose logging function, DES encryption, secure file access mode, AES CBC encryption, AES ECB encryption, no padding for RSA, and AES encryption alternative, An RSA weak key pair generator, a predictably generated pseudo-random number generator, an unencrypted socket, and possibly a TapJacking attack are all possible.
Due to the increasing number of hacking attempts and data breaches, users are more aware of mobile app security issues and choose secure apps over those whose data can be stolen with help of Appsealing. The app developers must therefore develop applications that satisfy the needs of the user while also addressing the issue of security.
