Available in PDF, EPUB and Kindle. Book excerpt: Bachelor Thesis from the year 2019 in the subject Computer Science - IT-Security, grade: 1,0, Technical University of Munich (Fakultät für Informatik), language: English, abstract: The topic of this thesis is to develop a graph-based static analysis framework for Java code that tolerates incomplete or non-compiling source code. For this purpose, the concept of Code Property Graphs (CPGs) is to be researched and extended, in order to provide information about more complex erroneous patterns in Java source code. Additionally, an evaluation of the resulting graph model is to be performed, by searching for cryptographic vulnerabilities in publicly available Java projects. This evaluation needs to show, whether this graph-based analysis approach is capable of finding security issues in Java code, and how feasible the analysis is from a performance point of view. Automatic code analysis is a widely used technique to find and eliminate errors in software projects. Instead of executing the program and verify that its behavior is correct, as dynamic analysis does it, static analysis is applied on its source code. Here, we search for suspicious patterns that are likely to indicate erroneous behavior. A special type of software bugs are those errors, that lead to security vulnerabilities. In this case, attackers may be able to undermine fundamental security aspects, by exfiltrating sensitive user data from server applications or assume control over the machine running the program in question. Security vulnerabilities in the code can have drastic consequences, which is why it is important to identify them as fast as possible and fix them immediately afterwards. This thesis extends the concept of Code Property Graphs (CPGs), which has been proposed for static analysis of C/C++ code, to be applied on programs and incomplete code snippets written in Java. Unifying Abstract Syntax Trees (ASTs), Control Flow Graphs (CFGs) and Data Flow Graphs (DFGs) in a single datastructure, this approach enables searching for vulnerabilities whose code patterns are spread out across the boundaries of single methods and classes. These patterns are identified using the graph query language cypher, which is provided by the graph database Neo4j. In an evaluation run on 100 public repositories on GitHub using cryptography, 135 findings of cryptographic API misuse have been identified using this technique. These include the use of insecure algorithms, like the Data Encryption Standard (DES) or Electronic Code Book mode (ECB), and hardcoded passwords that are used for encryption purposes. This thesis has been created in cooperation with Fraunhofer AISEC

Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2021 in the subject Computer Science - IT-Security, grade: 2,0, Technical University of Munich (Department of Informatics), language: English, abstract: This thesis extends a modified CPG approach that is able to operate on multiple programming languages, i.e. C/C++, Java, Python and Golang, available on GitHub3 [Fra21a]. Graph-based code analysis systems are versatile tools for reasoning about the correctness of complex software projects. One area in which they are widely used is in source code auditing: Security vulnerabilities, for example using cryptographic functions with insecure algorithms, can be introduced by coding patterns that spread over the boundaries of several methods, classes or even files in the project. This is where graph-based analysis makes finding these vulnerabilities easier, by creating a framework where the source code can be represented as a graph and vulnerable

Available in PDF, EPUB and Kindle. Book excerpt: With data explosion in many domains, such as social media, big code repository, Internet of Things (IoT), and inertial sensors, only 32% of data available to academic and industry is put to work, and the remaining 68% goes unleveraged. Moreover, people are facing an increasing number of obstacles concerning complex analytics on the sheer size of data, which include 1) how to perform dynamic graph analytics in a parallel and robust manner within a reasonable time? 2) How to conduct performance optimizations on a property graph representing and consisting of the semantics of code, data, and runtime systems for big data applications? 3) How to innovate neural graph approaches (i.e., Transformer) to solve realistic research problems, such as automated program repair and inertial navigation? To tackle these problems, I present two efforts along this road: efficient graph-based computation and intelligent graph analytics. Specifically, I firstly propose two theory-based dynamic graph models to characterize temporal trends in large social media networks, then implement and optimize them atop Apache Spark GraphX to improve their performances. In addition, I investigate a semantics-aware optimization framework consisting of offline static analysis and online dynamic analysis on a property graph representing the skeleton of a dataintensive application, to interactively and semi-automatically assist programmers to scrutinize the performance problems camouflaged in the source code. In the design of intelligent graph-based algorithms, I innovate novel neural graph-based approaches with multi-task learning techniques to repair a broad range of programming bugs automatically, and also improve the accuracy of pedestrian navigation systems in only consideration of sensor data of Inertial Measurement Units (IMU, i.e.accelerometer, gyroscope, and magnetometer). In this dissertation, I elaborate on the definitions of these research problems and leverage the knowledge of graph computation, program analysis, and deep learning techniques to seek solutions to them, followed by comprehensive comparisons with the state-of-the-art baselines and discussions on future research.

This book was released on 2017-09-07 with total page 852 pages. Available in PDF, EPUB and Kindle. Book excerpt: Software is an essential enabler for science and the new economy. It creates new markets and directions for a more reliable, flexible and robust society and empowers the exploration of our world in ever more depth, but it often falls short of our expectations. Current software methodologies, tools, and techniques are still neither robust nor reliable enough for the constantly evolving market, and many promising approaches have so far failed to deliver the solutions required. This book presents the keynote ‘Engineering Cyber-Physical Systems’ and 64 peer-reviewed papers from the 16th International Conference on New Trends in Intelligent Software Methodology Tools, and Techniques, (SoMeT_17), held in Kitakyushu, Japan, in September 2017, which brought together researchers and practitioners to share original research results and practical development experience in software science and related new technologies. The aim of the SoMeT conferences is to capture the essence of the new state-of-the-art in software science and its supporting technology and to identify the challenges such technology will have to master. The book explores new trends and theories which illuminate the direction of developments in this field, and will be of interest to anyone whose work involves software science and its integration into tomorrow’s global information society.
