Kate tries using Scrum and Kanban methodologies for project management but finds they are not effective. The project owner and team members go through multiple sprints of Scrum where things seem off and not quite right. They then try Kanban which seems to work better for their projects and teams. In the end, Kate advocates for finding a methodology that truly fits each individual project and team rather than following practices just for the sake of using a particular framework.
This document discusses enterprise agility and adaptive leadership. It describes three levels of agility within organizations: strategic, portfolio, and operational. Strategic agility allows an organization to create and respond to changes in a turbulent business environment. Portfolio agility focuses on high-value projects and reducing work bottlenecks. Operational agility refers to agile development practices. True enterprise agility requires an adaptive leadership approach that can facilitate organizational changes across all levels.
The document discusses communities of practice, which are informal groups of people who share a common domain of interest and work together to develop their knowledge and expertise. It provides examples of early communities of practice at Chrysler and Xerox, and defines the key elements of a community as having a domain, practice, and community. The rest of the document outlines reasons for using communities of practice, examples of how different organizations have implemented them, and recommendations for starting a new community of practice, including engaging members, establishing a shared vision, and finding ways to quickly provide value.
This document discusses test-driven development (TDD) for embedded C code. It covers the reasons for using TDD, how to apply TDD principles to embedded systems, and techniques for abstracting hardware and operating systems to allow for testing. Some key techniques mentioned include mocking the silicon, function pointer substitution, preprocessor substitution, and using TDD alongside a real-time operating system. The document argues that TDD finds bugs earlier and reduces debugging time compared to traditional "debug later" programming approaches.

Web security-–-everything-we-know-is-wrong-eoin-kearydrewz lin
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 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.
Appsec usa2013 js_libinsecurity_stefanodipaoladrewz lin
This document summarizes Stefano di Paola's talk on security issues with JavaScript libraries.

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_editsdrewz lin
(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.
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-exploitationsdrewz lin
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 martindrewz lin
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.
