The Construction of a Static Source Code Scanner Focused on SQL Injection Vulnerabilties in Java

SQL injection attacks are a significant threat to web application security, allowing attackers to execute arbitrary SQL commands and gain unauthorized access to sensitive data. Static source code analysis is a widely used technique to identify security vulnerabilities in software, including SQL injection attacks. However, existing static source code scanners often produce false positives and require a high level of expertise to use effectively. This thesis presents the design and implementation of a static source code scanner for SQL injection vulnerabilities in Java queries. The scanner uses a combination of pattern matching and data flow analysis to detect SQL injection vulnerabilities in code. The scanner identifies vulnerable code by analyzing method calls, expressions, and variable declarations to detect potential vulnerabilities. To evaluate the scanner, malicious SQL code is manually injected in queries to test the scanner\u27s ability to detect vulnerabilities. The results showed that the scanner could identify a high percentage of SQL injection vulnerabilities. The limitations of the scanner include the inability to detect runtime user input validation and the reliance on predefined patterns and heuristics to identify vulnerabilities. Despite these limitations, the scanner provides a useful tool for junior developers to identify and address SQL injection vulnerabilities in their code. This thesis presents a static source code scanner that can effectively detect SQL injection vulnerabilities in Java web applications. The scanner\u27s design and implementation provide a useful contribution to the field of software security, and future work could focus on improving the scanner\u27s precision and addressing its limitations

User Review Analysis for Requirement Elicitation: Thesis and the framework prototype's source code

Online reviews are an important channel for requirement elicitation. However, requirement engineers face challenges when analysing online user reviews, such as data volumes, technical supports, existing techniques, and legal barriers. Juan Wang proposes a framework solving user review analysis problems for the purpose of requirement elicitation that sets up a channel from downloading user reviews to structured analysis data. The main contributions of her work are: (1) the thesis proposed a framework to solve the user review analysis problem for requirement elicitation; (2) the prototype of this framework proves its feasibility; (3) the experiments prove the effectiveness and efficiency of this framework. This resource here is the latest version of Juan Wang's PhD thesis "User Review Analysis for Requirement Elicitation" and all the source code of the prototype for the framework as the results of her thesis

Towards an aspect weaving BPEL engine

This position paper proposes the use of dynamic aspects and the visitor design pattern to obtain a highly configurable and extensible BPEL engine. Using these two techniques, the core of this infrastructural software can be customised to meet new requirements and add features such as debugging, execution monitoring, or changing to another Web Service selection policy. Additionally, it can easily be extended to cope with customer-specific BPEL extensions. We propose the use of dynamic aspects not only on the engine itself but also on the workflow in order to tackle the problems of Web Service hot deployment and hot fixes to long running processes. In this way, composing aWeb Service "on-the-fly" means weaving its choreography interface into the workflow
