FUZZINGMaster One of Today's Most Powerful Techniques for Revealing Security Flaws!Fuzzing has evolved into one of today's most effective approaches to test software security. To “fuzz,” you attach a program's inputs to a source of random data, and then systematically identify the failures that arise. Hackers haverelied on fuzzing for years: Now, it's your turn. In this book, renowned fuzzing experts show you how to use fuzzing to reveal weaknesses in your software before someone else does.Fuzzing is the first and only book to cover fuzzing from start to finish, bringing disciplined best practices to a technique that has traditionally been implemented informally. The authors begin by reviewing how fuzzing works and outlining its crucial advantages over other security testing methods. Next, they introduce state-of-the-art fuzzing techniques for finding vulnerabilities in network protocols, file formats, and web applications; demonstrate the use of automated fuzzing tools; and present several insightful case histories showing fuzzing at work. Coverage includes:· Why fuzzing simplifies test design and catches flaws other methods miss· The fuzzing process: from identifying inputs to assessing “exploitability”· Understanding the requirements for effective fuzzing· Comparing mutation-based and generation-based fuzzers· Using and automating environment variable and argument fuzzing· Mastering in-memory fuzzing techniques· Constructing custom fuzzing frameworks and tools· Implementing intelligent fault detectionAttackers are already using fuzzing. You should, too. Whether you're a developer, security engineer, tester, or QA specialist, this book teaches you how to build secure software.Forewordï ï ï ï xix Prefaceï ï ï ï ï ï ï xxiAcknowledgmentsï xxvAbout the Authorï ï xxvii PARTIï ï ï ï ï ï ï ï BACKGROUNDï ï ï ï 1Chapter 1ï ï ï Vulnerability Discovery Methodologiesï 3Chapter 2ï ï ï What Is Fuzzing__ __ï ï 21Chapter 3ï ï ï Fuzzing Methods and Fuzzer Typesï ï ï ï 33Chapter 4ï ï ï Data Representation and Analysisï ï ï ï ï ï ï 45Chapter 5ï ï ï Requirements for Effective Fuzzingï ï ï ï ï 61PART IIï ï ï ï ï TARGETS AND AUTOMATIONï ï ï ï ï ï ï ï ï 71Chapter 6ï ï ï Automation and Data Generationï ï ï ï ï ï ï 73Chapter 7ï ï ï Environment Variable and Argument Fuzzing 89Chapter 8ï ï ï Environment Variable and Argument Fuzzing: Automation 103Chapter 9ï ï ï Web Application and Server Fuzzingï ï ï ï 113Chapter 10ï Web Application and Server Fuzzing: Automationï ï ï 137Chapter 11ï File Format Fuzzingï ï ï ï ï ï ï ï 169Chapter 12ï File Format Fuzzing: Automation on UNIXï ï ï ï 181Chapter 13ï File Format Fuzzing: Automation on Windowsï ï ï ï ï ï ï ï 197Chapter 14ï Network Protocol Fuzzingï ï ï ï ï ï ï ï 223Chapter 15ï Network Protocol Fuzzing: Automation on UNIXï ï ï ï 235Chapter 16ï Network Protocol Fuzzing: Automation on Windowsï ï ï ï ï ï ï ï 249Chapter 17ï Web Browser Fuzzingï ï ï ï ï 267Chapter 18ï Web Browser Fuzzing: Automationï ï ï ï 283Chapter 19ï In-Memory Fuzzingï¾ ï¾ ï¾ ï¾ ï¾ ï¾ ï¾ ï¾ 301Chapter 20ï¾ In-Memory Fuzzing: Automationï¾ ï¾ ï¾ ï¾ ï¾ ï¾ ï¾ ï¾ 315PART IIIï¾ ï¾ ï¾ ADVANCED FUZZING TECHNOLOGIESï¾ ï¾ ï¾ ï¾ ï¾ 349Chapter 21ï¾ Fuzzing Frameworksï¾ ï¾ ï¾ ï¾ ï¾ ï¾ 351Chapter 22ï¾ Automated Protocol Dissectionï¾ 419Chapter 23ï¾ Fuzzer Trackingï¾ ï¾ ï¾ ï¾ 437Chapter 24ï¾ Intelligent Fault Detection 471PART IVï¾ ï¾ ï¾ ï¾ LOOKING FORWARDï¾ ï¾ ï¾ 495Chapter 25ï¾ Lessons Learnedï¾ ï¾ ï¾ 497Chapter 26ï¾ Looking Forwardï¾ ï¾ ï¾ 507Index 519
