Software Verification and Analysis

Software Verification and Analysis PDF Author: Janusz Laski
Publisher: Springer Science & Business Media
ISBN: 1848822405
Category : Computers
Languages : en
Pages : 234

Book Description
“The situation is good, but not hopeless” (Polish folk wisdom) The text is devoted to the Software Analysis and Testing (SAT) methods and s- porting tools for assessing and, if possible, improving software quality, specifically its correctness. The term quality assurance is avoided for it is this author’s firm belief that in the current state of the art that goal is unattainable, a plethora of “gu- anteed” solutions to the problem notwithstanding. Therefore, the rather awkward phrase “improving correctness” is to be understood as an effort to minimize the number of residual programming faults (“bugs”) and their impact on the software’s behavior, that is, to make the faults tolerable. It is clear that such a minimalist approach is a result of frustration. Indeed, having spent years developing software and teaching (preaching?) “How to do it right,” I still do not know how to go about it with any degree of certainty! It appears then I probably should stop right now, for who with a modicum of common sense would reach for a text that does not offer salvation but (as will be seen) hard work and misery? If I intend to continue, it is only that I suspect there are many professionals out there who have similar doubts. And they are the intended audience of this project. The philosophical underpinning of the text is the importance of sound engine- ing practices in software development.

Reference Information for the Software Verification and Validation Process

Reference Information for the Software Verification and Validation Process PDF Author: Dolores R. Wallace
Publisher: DIANE Publishing
ISBN: 0788143409
Category : Computers
Languages : en
Pages : 85
Book Description
Computing systems are employed in the health care environment in efforts to increase reliability of care and reduce costs. Software verification and validation (V&V) is an aid in determining that the software requirements are implemented correctly and completely and are traceable to system requirements. It helps to ensure that those system functions controlled by software are secure, reliable, and maintainable. Software V&V is conducted throughout the planning, development and maintenance of software systems, including knowledge based systems, and may assist in assuring appropriate reuse of software.

String Analysis for Software Verification and Security

String Analysis for Software Verification and Security PDF Author: Tevfik Bultan
Publisher: Springer
ISBN: 3319686704
Category : Computers
Languages : en
Pages : 174
Book Description
This book discusses automated string-analysis techniques, focusing particularly on automata-based static string analysis. It covers the following topics: automata-bases string analysis, computing pre and post-conditions of basic string operations using automata, symbolic representation of automata, forward and backward string analysis using symbolic automata representation, constraint-based string analysis, string constraint solvers, relational string analysis, vulnerability detection using string analysis, string abstractions, differential string analysis, and automated sanitization synthesis using string analysis. String manipulation is a crucial part of modern software systems; for example, it is used extensively in input validation and sanitization and in dynamic code and query generation. The goal of string-analysis techniques and this book is to determine the set of values that string expressions can take during program execution. String analysis can be used to solve many problems in modern software systems that relate to string manipulation, such as: (1) Identifying security vulnerabilities by checking if a security sensitive function can receive an input string that contains an exploit; (2) Identifying possible behaviors of a program by identifying possible values for dynamically generated code; (3) Identifying html generation errors by computing the html code generated by web applications; (4) Identifying the set of queries that are sent to back-end database by analyzing the code that generates the SQL queries; (5) Patching input validation and sanitization functions by automatically synthesizing repairs illustrated in this book. Like many other program-analysis problems, it is not possible to solve the string analysis problem precisely (i.e., it is not possible to precisely determine the set of string values that can reach a program point). However, one can compute over- or under-approximations of possible string values. If the approximations are precise enough, they can enable developers to demonstrate existence or absence of bugs in string manipulating code. String analysis has been an active research area in the last decade, resulting in a wide variety of string-analysis techniques. This book will primarily target researchers and professionals working in computer security, software verification, formal methods, software engineering and program analysis. Advanced level students or instructors teaching or studying courses in computer security, software verification or program analysis will find this book useful as a secondary text.

SPIN Model Checking and Software Verification

SPIN Model Checking and Software Verification PDF Author: Klaus Havelund
Publisher: Springer Science & Business Media
ISBN: 3540410309
Category : Computers
Languages : en
Pages : 346
Book Description
The SPIN workshop is a forum for researchers interested in the subject of automata-based, explicit-state model checking technologies for the analysis and veri?cation of asynchronous concurrent and distributed systems. The SPIN - del checker (http://netlib.bell-labs.com/netlib/spin/whatispin.html), developed by Gerard Holzmann, is one of the best known systems of this kind, and has attracted a large user community. This can likely be attributed to its e?cient state exploration algorithms. The fact that SPIN’s modeling language, Promela, resembles a programming language has probably also contributed to its success. Traditionally, the SPIN workshops present papers on extensions and uses of SPIN. As an experiment, this year’s workshop was broadened to have a slightly wider focus than previous workshops in that papers on software veri?cation were encouraged. Consequently, a small collection of papers describe attempts to analyze and verify programs written in conventional programming languages. Solutions include translations from source code to Promela, as well as specially designed model checkers that accept source code. We believe that this is an - teresting research direction for the formal methods community, and that it will result in a new set of challenges and solutions. Of course, abstraction becomes the key solution to deal with very large state spaces. However, we also see - tential for integrating model checking with techniques such as static program analysis and testing. Papers on these issues have therefore been included in the proceedings.
