Web security-–-everything-we-know-is-wrong-eoin-keary
1) Web application security is often approached incorrectly, focusing too much on annual penetration tests and compliance, rather than ongoing monitoring and prevention through the development process.
2) Many vulnerabilities are introduced through third party libraries and dependencies, which are not properly tested or managed. Continuous testing across the full software supply chain is needed.
3) Not all vulnerabilities are equal - context is important. A risk-based approach should prioritize the most critical issues based on factors like impact, likelihood, and the development environment. Compliance alone does not ensure real security.

This document discusses sandboxing untrusted JavaScript from third parties to improve security. It proposes a two-tier sandbox architecture that uses JavaScript libraries and wrappers, without requiring browser modifications. Untrusted code is executed in an isolated environment defined by policy code, and can only access approved APIs. This approach aims to mediate access between code and the browser securely and efficiently while maintaining compatibility with existing third-party scripts.

The document discusses research conducted by Gregg Ganley and Gavin Black at MITRE in FY13-14 on iOS mobile application security. It describes their work on a tool called iMAS (iOS Mobile Application Security) which aims to provide additional security controls and containment for native iOS applications. iMAS addresses vulnerabilities related to runtime access, device access, application access, data at rest, and threats from app stores/malware. It utilizes techniques like encrypted code modules, forced inlining, secure MDM and more to raise security levels above standard iOS but below a fully customized/rooted mobile device environment. The document outlines the motivation, capabilities and future research directions for the iMAS project.
Defeating xss-and-xsrf-with-my faces-frameworks-steve-wolf
This document discusses how to defeat cross-site scripting (XSS) and cross-site request forgery (XSRF) when using JavaServer Faces (JSF) frameworks. It covers validating user input, encoding output, and protecting view states to prevent XSS, as well as configuring JSF implementations to protect against XSRF by encrypting view states and adding tokens to URLs. The presentation emphasizes testing validation, encoding, and protection in specific JSF implementations since behaviors can differ.
Csrf not-all-defenses-are-created-equal
This document summarizes a presentation on defending against CSRF (cross-site request forgery) attacks. It discusses four main design patterns for CSRF defenses: the synchronizer token pattern, double submit cookies, challenge-response systems, and checking the referrer header. It then provides details on implementing these patterns, specifically looking at libraries and features in .NET, .NET MVC, Anticsrf, CSRFGuard, and HDIV that can help implement CSRF tokens and validation. The document covers the tradeoffs of different approaches and considerations for using them effectively on the code and server level.

This document provides a summary of a presentation by Robert Hansen on the future of browser security. Hansen argues that while browser developers want to improve security and privacy, their companies' business models focused on advertising revenue prohibit them from doing so. He outlines various techniques used by advertisers and browser companies to track users against their preferences. Hansen advocates for technical controls that allow users to opt out of tracking through a "can not track" approach, rather than relying on ineffective "do not track" policies. He concludes by discussing WhiteHat Security's focus on privacy and their plans to add more security and privacy features to their Aviator browser.

This document summarizes Stefano di Paola's talk on security issues with JavaScript libraries. It discusses how jQuery's $() method can be considered a "sink" that executes HTML passed to it, including examples of XSS via jQuery selectors and AJAX calls. It also covers problems with JSON parsing regular expressions, AngularJS expression injection, and credentials exposed in URLs. Solutions proposed include validating all input, auditing third-party libraries, and moving away from approaches like eval() that execute untrusted code.
Appsec2013 presentation-dickson final-with_all_final_edits
(1) A study surveyed 600 software developers and found that most did not have a basic understanding of software security concepts, with 73% failing an initial survey and the average score being 59% before training. (2) However, after training, developers' understanding of key concepts increased, with some areas like cross-site scripting seeing a 20 percentage point gain. (3) The study concluded that targeted security training can improve developers' knowledge in the short-term, though retention of this knowledge may require refresher training over time.
Appsec2013 presentation
This document summarizes Bruno Gonçalves de Oliveira's talk on hacking web file servers for iOS. It introduces Bruno and his background in offensive security and discusses how iOS devices store a lot of information and mobile applications are often poorly designed and vulnerable. It provides examples of vulnerable file storage apps, outlines features and vulnerabilities like lack of encryption, authentication, XSS issues, and path traversal flaws. The document demonstrates exploits like unauthorized access to file systems on jailbroken devices and how to find vulnerable systems through mDNS queries. It concludes that mobile apps are the future but designers still do not prioritize security and there are too many apps for users to vet carefully.
Appsec 2013-krehel-ondrej-forensic-investigations-of-web-exploitations
This document discusses forensic investigations of web exploitations. It presents a scenario where a web server in a DMZ zone was exploited but logs are unavailable, so network traffic must be analyzed. Wireshark will be used to analyze a PCAP file of recorded traffic to determine what happened and find any traces of commands or malware. The document also provides information on the costs of different types of cyber attacks, how to decode HTTP requests, and discusses tools that can be used for network forensics investigations like Wireshark, tcpdump, and Xplico.
Appsec2013 assurance tagging-robert martin
The document discusses engineering software systems to be more secure against attacks. It notes that reducing a system's attack surface alone is not enough, as software and networks are too complex and it is impossible to know all vulnerabilities. It then discusses characteristics of advanced persistent threats, including that the initial attack may go unnoticed and adversaries cannot be fully kept out. Finally, it argues that taking a threat-driven perspective beyond just operational defense can help balance mitigation with detection and response.
