Static Analysis the Workhorse of a End-To-End Securitye Testing Strategy
Static Analysis The Workhorse of a End-to-End Securitye Testing Strategy Achim D. Brucker [email protected] http://www.brucker.uk/ Department of Computer Science, The University of Sheffield, Sheffield, UK Winter School SECENTIS 2016 Security and Trust of Next Generation Enterprise Information Systems February 8–12, 2016, Trento, Italy Static Analysis: The Workhorse of a End-to-End Securitye Testing Strategy Abstract Security testing is an important part of any security development lifecycle (SDL) and, thus, should be a part of any software (development) lifecycle. Still, security testing is often understood as an activity done by security testers in the time between “end of development” and “offering the product to customers.” Learning from traditional testing that the fixing of bugs is the more costly the later it is done in development, security testing should be integrated, as early as possible, into the daily development activities. The fact that static analysis can be deployed as soon as the first line of code is written, makes static analysis the right workhorse to start security testing activities. In this lecture, I will present a risk-based security testing strategy that is used at a large European software vendor. While this security testing strategy combines static and dynamic security testing techniques, I will focus on static analysis. This lecture provides a introduction to the foundations of static analysis as well as insights into the challenges and solutions of rolling out static analysis to more than 20000 developers, distributed across the whole world.

Static Program Analysis Via 3-Valued Logic
Static Program Analysis via 3-Valued Logic ¡ ¢ £ Thomas Reps , Mooly Sagiv , and Reinhard Wilhelm ¤ Comp. Sci. Dept., University of Wisconsin; [email protected] ¥ School of Comp. Sci., Tel Aviv University; [email protected] ¦ Informatik, Univ. des Saarlandes;[email protected] Abstract. This paper reviews the principles behind the paradigm of “abstract interpretation via § -valued logic,” discusses recent work to extend the approach, and summarizes on- going research aimed at overcoming remaining limitations on the ability to create program- analysis algorithms fully automatically. 1 Introduction Static analysis concerns techniques for obtaining information about the possible states that a program passes through during execution, without actually running the program on specific inputs. Instead, static-analysis techniques explore a program’s behavior for all possible inputs and all possible states that the program can reach. To make this feasible, the program is “run in the aggregate”—i.e., on abstract descriptors that repre- sent collections of many states. In the last few years, researchers have made important advances in applying static analysis in new kinds of program-analysis tools for identi- fying bugs and security vulnerabilities [1–7]. In these tools, static analysis provides a way in which properties of a program’s behavior can be verified (or, alternatively, ways in which bugs and security vulnerabilities can be detected). Static analysis is used to provide a safe answer to the question “Can the program reach a bad state?” Despite these successes, substantial challenges still remain. In particular, pointers and dynamically-allocated storage are features of all modern imperative programming languages, but their use is error-prone: ¨ Dereferencing NULL-valued pointers and accessing previously deallocated stor- age are two common programming mistakes. -

On the other hand, it is not significant attention from the scientific community, yet which uncommon for academic and scientific researchers to believe have potential for profound real world impact, formulating these that most of the problems faced by industrialists are either as research questions that, we believe, are ripe for exploration and that would make excellent topics for research projects. boring, tedious or scientifically uninteresting. This sociological phenomenon has led to a great deal of miscommunication between the academic and industrial sectors. I.

Using Static Program Analysis to Aid Intrusion Detection
Using Static Program Analysis to Aid Intrusion Detection Manuel Egele, Martin Szydlowski, Engin Kirda, and Christopher Kruegel Secure Systems Lab Technical University Vienna fpizzaman,msz,ek,[email protected] Abstract. The Internet, and in particular the world-wide web, have be- come part of the everyday life of millions of people. With the growth of the web, the demand for on-line services rapidly increased. Today, whole industry branches rely on the Internet to do business. Unfortunately, the success of the web has recently been overshadowed by frequent reports of security breaches. Attackers have discovered that poorly written web applications are the Achilles heel of many organizations. The reason is that these applications are directly available through firewalls and are of- ten developed by programmers who focus on features and tight schedules instead of security. In previous work, we developed an anomaly-based intrusion detection system that uses learning techniques to identify attacks against web- based applications. That system focuses on the analysis of the request parameters in client queries, but does not take into account any infor- mation about the protected web applications themselves. The result are imprecise models that lead to more false positives and false negatives than necessary. In this paper, we describe a novel static source code analysis approach for PHP that allows us to incorporate information about a web application into the intrusion detection models. The goal is to obtain a more precise characterization of web request parameters by analyzing their usage by the program. This allows us to generate more precise intrusion detection models. -

The Common Gateway Interface and Server-Side Programming
WebWeb MasterMaster 11 IFIIFI Andrea G. B. Tettamanzi Université de Nice Sophia Antipolis Département Informatique [email protected] Andrea G. B. Tettamanzi, 2019 1 Unit 3 The Common Gateway Interface and Server-side Programming Andrea G. B. Tettamanzi, 2019 2 Agenda • The Common Gateway Interface • Server-Side Programming Andrea G. B. Tettamanzi, 2019 3 Introduction • An HTTP server is often used as a gateway to a different information system (legacy or not), for example – an existing body of documents – an existing database application • The Common Gateway Interface (CGI) is an agreement between HTTP server implementors about how to integrate such gateway scripts and programs • It was typically (but not exclusively) used in conjunction with HTML forms to build database applications • Nowadays largely superseded by dynamic Web content technologies such as PHP, ASP.NET, Java Servlets, and Node.js Andrea G. B. Tettamanzi, 2019 4 The Common Gateway Interface • The Common Gateway Interface (CGI) is a de facto standard protocol for Web servers to execute an external program that generates a Web page dynamically • The external program executes like a console application running on the same machine as the Web server (the host) • Such program is known as a CGI script or simply as a CGI Andrea G. B. Tettamanzi, 2019 5 How Does That Work? • Each time a client requests the URL corresponding to a CGI program, the server will execute it in real-time – E.g.: GET http://www.example.org/cgi-bin/add?x=2&y=2 • The output of the program will go more or less directly to the client • Strictly speaking, the “input” to the program is the HTTP request • Environment variables are used to pass data about the request from the server to the program – They are accessed by the script in a system-defined manner – Missing environment variable = NULL value – Character encoding is system-defined Andrea G. -
