  • Systematization of Vulnerability Discovery Knowledge: Review
    Systematization of Vulnerability Discovery Knowledge Review Protocol Nuthan Munaiah and Andrew Meneely Department of Software Engineering Rochester Institute of Technology Rochester, NY 14623 {nm6061,axmvse}@rit.edu February 12, 2019 1 Introduction As more aspects of our daily lives depend on technology, the software that supports this technology must be secure. We, as users, almost subconsciously assume the software we use to always be available to serve our requests while preserving the confidentiality and integrity of our information. Unfortunately, incidents involving catastrophic software vulnerabilities such as Heartbleed (in OpenSSL), Stagefright (in Android), and EternalBlue (in Windows) have made abundantly clear that software, like other engineered creations, is prone to mistakes. Over the years, Software Engineering, as a discipline, has recognized the potential for engineers to make mistakes and has incorporated processes to prevent such mistakes from becoming exploitable vulnerabilities. Developers leverage a plethora of processes, techniques, and tools such as threat modeling, static and dynamic analyses, unit/integration/fuzz/penetration testing, and code reviews to engineer secure software. These practices, while effective at identifying vulnerabilities in software, are limited in their ability to describe the engineering failures that may have led to the introduction of vulnerabilities. Fortunately, as researchers propose empirically-validated metrics to characterize historical vulnerabilities, the factors that may have led to the introduction of vulnerabilities emerge. Developers must be made aware of these factors to help them proactively consider security implications of the code that they contribute. In other words, we want developers to think like an attacker (i.e. inculcate an attacker mindset) to proactively discover vulnerabilities.

Jadhav#2 21Bharati Vidyapeeth University Yashwantrao Mohite institute of Management, Karad [M.S.], INDIA Abstract: Android has the biggest market share among all Smartphone operating system. The number of devices running with the Android operating system has been on the rise. By the end of 2012, it will account for nearly half of the world's Smartphone market. Along with its growth, the importance of security has also risen. Security is one of the main concerns for Smartphone users today. As the power and features of Smartphone’s increase, so has their vulnerability for attacks by viruses etc. Perhaps android is more secured operating system than any other Smartphone operating system today. Android has very few restrictions for developer, increases the security risk for end users. Antivirus Android apps remain one of the most popular types of applications on Android. Some people either like having that extra security or just want to be extra cautious just in case and there is nothing wrong with that. In this list, we’ll check out the best antivirus Android apps and anti-malware apps on Android! The efficacies of these applications have not been empirically established. This paper analyzes some of the security tools written for the Android platform to gauge their effectiveness at mitigating spyware and malware.

Unfortunately, these properties also leave Android vulnerable, attracting attacks for profit or fun. To mitigate these threats, numerous issue-specific solutions have been proposed. With the increasing number and complexity of security problems and solutions, we believe this is the right moment to step back and systematically re-evaluate the Android security architecture and security practices in the ecosystem. We organize the most recent security research on the Android platform into two categories: the software stack and the ecosystem. For each category, we provide a comprehensive narrative of the problem space, highlight the limitations of the proposed solutions, and identify open problems for future research. Based on our collection of knowledge, we envision a blueprint for engineering a secure, next-generationr Android ecosystem.

  • Security Analysis of Android OS
    Security Analysis Of Android OS Jeet Mohapatra, Mark Wang, Mike Wang 1. Introduction The primary motivation for the project was the news about Wikileaks releasing a trove of hacking tools employed by the CIA. This includes tools and techniques which can hack phones. However, this information was later redacted, and so after investigating the vault released by Wikileaks, no information or knowledge was gained. Instead, other sources were used to research and learn about attacks. Android is a very robust system with a dedicated team to identify and patch problems. As a result, many of the attacks described within the paper do not work on modern versions of Android. 2. Security Policy of Android We can define the Android security through two different roles. For one role, we have the Android App Developers and for the other role, we have the users. First let us list some assumptions for each role. Android App Developers: • Has certain non-dangerous permissions automatically granted to them • Can communicate with other apps with own app • Can ask for more permissions over phone • Has access to the Android API Users: • Chooses which programs to download • Can grant permissions for other apps • Assumes Android provides basic protection from attacks We make the assumption that most of the attacks on the Android either involves some sort of malicious code execution or network attack. For malicious code, the most common way of inserting it will be through an app. There are certain security mechanisms on the phone that help prevent malicious code from hijacking the phone. Here are some following mechanism: Security Mechanisms: 1 • Application Sandbox: Each app runs on its own process and is monitored by the kernel.

  • Chapter 12 CATEGORIZING MOBILE DEVICE MALWARE BASED ON
    Chapter 12 CATEGORIZING MOBILE DEVICE MALWARE BASED ON SYSTEM SIDE-EFFECTS Zachary Grimmett, Jason Staggs and Sujeet Shenoi Abstract Malware targeting mobile devices is an ever increasing threat. The most insidious type of malware resides entirely in volatile memory and does not leave a trail of persistent artifacts. Such malware requires novel detection and capture methods in order to be reliably identified, an- alyzed and mitigated. This chapter proposes malware categorization and detection techniques based on measurable system side-effects ob- served in an exploited mobile device. Using the Stagefright family of exploits as a case study, common system side-effects produced as a result of attempted exploitation are identified. These system side-effects are leveraged to trigger volatile memory (i.e., RAM) collection by memory acquisition tools (e.g., LiME) to enable analysis of the malware. Keywords: Mobile malware, memory-resident, categorization, system side-effects 1. Introduction Critical vulnerabilities that affect large families of mobile devices make it imperative to develop new techniques for securing these devices against increasingly sophisticated attacks as well as for conducting forensic in- vestigations. Investigating attacks on mobile devices requires the cap- ture and analysis of evidence pertaining to attacks. However, the most insidious malware resides entirely in memory and does not create per- sistent artifacts. Memory-resident malware that removes itself from a mobile device after performing its malicious activities can evade capture and analysis by malware investigators, even after its presence has been detected by a user. Live memory acquisition is the only way to recover memory-resident malware from exploited devices.
