Source code vulnerability thesis

In this thesis, we develop techniques for vulnerability analysis and defense that only require access to vulnerable programs in binary form our approach does not use or require source code we focus on a binary-centric approach since everyone typically has access to the binary code for the programs they. This thesis proposes a solution for the problem of identifying non-persistent xss vul- nerabilities in php code by demonstrating a system which is capable of finding these vul- nerable code paths this is achieved through the use of static taint analysis, whereby a number of known sources of untrusted data. This thesis evaluated five static analysis tools--polyspace c verifier, archer, boon, splint, and uno--using 14 code examples that illustrated actual buffer overflow vulnerabilities found in various versions of sendmail, bind, and wu- ftpd each code example included a bad case with one or more buffer overflow. Discovery of vulnerabilities in source code our method proceeds by embedding code in a vector space and auto- matically determining api usage patterns using machine learning starting from a known vulnerability, these patterns can be exploited to guide the auditing of code and to identify potentially vulnerable code with. Questions to ask yourself when choosing an open-source static code analysis tool: does the tool support your language (s) what types of vulnerabilities and code issues do you need to look for in your code will this tool work within your ide for immediate feedback and faster remediation what's the. Master of science in computer science abstract this thesis presents the results of an evaluation of source code analyzers such tools constitute an inexpensive, efficient and fast way of removing the most common vulnerabilities in a software project, even though not all security flaws can be detected.

For inclusion in graduate theses and dissertations by an authorized administrator of iowa state university digital repository for more i would like to dedicate this dissertation to my amazing daughter morgana who was there and/or detect vulnerabilities to injection attacks in queries and/or in application source code. Web application forms the thesis proposes methodologies and tools for the detection of input valida- tion vulnerabilities in source code and for the protection of web applications written in php, using source code static analysis, machine learning and runtime protection techniques an approach based on.

Abstract—various security-oriented static analysis tools are designed to detect potential input validation vulnerabilities early in the development process to verify and resolve these vulnera- bilities, developers must retrace problematic data flows through the source code my thesis proposes that existing tools do not. This methodology it should be possible to detect vulnerabilities in any web framework, preferably in a (partially) automated in this thesis we present our approach and the design of the benchmark we however, not only speed and beauty of the code are important factors to consider when building web. Vulnerabilities have a lifecycle, which starts from its creation when it is introduced in the source code by the developer, and finishes when a patch for it is installed, illustrated in figure 12 [28] in the context of this thesis, we focus on the post- disclosure risk segment, vulnerabilities that have been disclosed.

Automatic vulnerability detection using static source code analysis by alexander ivanov sotirov a thesis submitted in partial fulfillment of the requirements for the degree of master of science in the department of computer science in the graduate school of the university. This dissertation argues that static analysis can be a powerful tool for software assurance, providing a new to nd serious new vulnerabilities in a large, widely deployed software package (even though it had already been for automated detection of potential bu er overrun vulnerabilities in security-critical source code,. For our purposes, a source code security analyzer examines source code to detect and report weaknesses that can lead to security vulnerabilities they are one of the last lines of defense to eliminate software vulnerabilities during development or after deployment a source code security analysis tool functional.
