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

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

This research aims to develop a hybrid methodology to support lean management to improve the sustainability of the construction phase. The combination of Value Stream Mapping and Process-based Life Cycle Assessment is enhanced by integrating with simulation methods to consider the environmental performance of the construction phase. Data from predefined process patterns, Life Cycle Assessment databases, and Building Information Modelling models, are used as input to the simulation-based Value Stream Mapping model. This methodology will enable an examination of the environmental impact of particular situations as what-if scenarios, during the planning and construction phases, without compromising the achievement of the construction process objectives.
