Effective software vulnerability detection for web services

该项目旨在设计和实施新的更好的方法来发现通过网络或云提供的软件服务中的漏洞，以及证明不存在某些类型的漏洞的方法。所谓的注入攻击无处不在，通常被认为是当今互联网上最重要的安全威胁。用于软件服务的编程语言倾向于使用字符串作为通用数据结构，不幸的是，这使得很难将受信任的代码与不受信任的用户提供的数据分开。本项目旨在开发新的程序分析工具和字符串约束求解器，并使用这些工具来支持关于字符串处理软件的复杂自动推理。

This project aims to design and implement new and better methods to find vulnerabilities in software services delivered over the web or through the cloud, as well as methods for proving the absence of certain types of vulnerability. So-called injection attacks are pervasive and generally considered the most important security threat on today's Internet. The programming languages used for software services tend to use strings as a universal data structure, which unfortunately makes it hard to separate trusted code from untrusted user-provided data. This project intends to develop novel program analysis tools and string constraint solvers, and employ these tools to support sophisticated automated reasoning about string manipulating software.
