AJAX is a web development technique that allows web pages to be updated asynchronously by exchanging data with a web server behind the scenes, without interfering with the display and behavior of the existing page. While AJAX can improve interactivity, it also introduces some security risks similar to regular web applications, such as cross-site request forgery and malware being introduced through malicious JavaScript code. Developers need to implement authentication, authorization, and data protection to secure AJAX applications and users can help defend themselves using tools like NoScript to block untrusted scripts.
This talk highlights potential attacks against web application using Ajax and XHR technology. The first part of the talk introduces Ajax and related technologies. Second part of the talk focuses on potential attacks and consequences, including some scenario where SOP (Same of origin) policy is bypassed.
Insecure software undermines our infrastructure and puts our organizations at risk. Whether you’re a new developer, a designer who is beginning to experiment with programming, or a seasoned developer looking for a refresher, join us as we discuss why attacks happen, go over the most common vulnerabilities and techniques you can use to code defensively. This hands-on workshop will feature real-world hacking exercises that correspond to each of the Open Web Application Security Project (OWASP) top 10 vulnerabilities, helping to hone your skills as a security ninja!

Build A Killer Client For Your REST+JSON APIStormpath
REST+JSON APIs are great - but you still need to communicate with them from your code. Wouldn't you prefer to interact with clean and intuitive Java objects instead of messing with HTTP requests, HTTP status codes and JSON parsing? Wouldn't you prefer to work with type-safe objects specific to your API?
In this presentation, Les Hazlewood - Stormpath CTO and Apache Shiro PMC Chair - will share all of the golden nuggets learned while designing, implementing and supporting multiple clients purpose-built for a real-world REST+JSON API.

Token Authentication for Java ApplicationsStormpath
Everyone building a web application that supports user login is concerned with security. How do you securely authenticate users and keep their identity secure? With the huge growth in Single Page Applications (SPAs), JavaScript and mobile applications, how do you keep users safe even though these are 'unsafe' client environments?
This presentation will demystify HTTP Authentication and explain how the Next Big Thing - Token Authentication - can be used to secure web applications on the JVM, REST APIs, and 'unsafe' clients while supporting security best practices and even improving your application's performance and scale.
Access Control is a necessary security control at almost every layer within a web application. This talk will discuss several of the key access control anti-patterns commonly found during website security audits. These access control anti-patterns include hard-coded security policies, lack of horizontal access control, and "fail open" access control mechanisms. In reviewing these and other access control problems, we will discuss and design a positive access control mechanism that is data contextual, activity based, configurable, flexible, and deny-by-default - among other positive design attributes that make up a robust web-based access-control mechanism.
BsidesDelhi 2018: DomGoat - the DOM Security PlaygroundBSides Delhi
Presenter: Lavakumar Kuppan
Abstract: In a Mobile application pentest the tester focuses on identifying vulnerabilities on both the mobile app and the backend service the app talks to. However, in a web application pentest the client-side is usually ignored and the focus is placed entirely on security issues on the server-side. Modern browsers have several capabilities which make the JS code running in the browser almost as complex powerful as a mobile app and by extension also prone to serious security issues. Most pentesters remain unaware of these security issues and their severity. DOMGoat is an open source application that is developed primarily to help pentesters understand the various client-side security issues that can occur in the DOM. This includes everything from the several variants of DOM XSS to JavaScript cryptography to client-side data leakage and more. This talk will explain the various security issues that affect the DOM and also show how DOMGoat can be used to learn about these issues.

The federal budget deficit for fiscal year 2014 will
amount to $506 billion, CBO estimates, roughly
$170 billion lower than the shortfall recorded in 2013.
At 2.9 percent of gross domestic product (GDP), this
year’s deficit will be much smaller than those of recent years (which reached almost 10 percent of GDP in 2009) and slightly below the average of federal deficits over the past 40 years.
JavaScript controls our lives – we use it to zoom in and out of a map, to automatically schedule doctor appointments and toplay online games. But have we ever properly considered thesecurity state of this scripting language? Before dismissing the (in)security posture of JavaScript on the grounds of a client-side problem, consider the impact ofJavaScript vulnerability exploitation to the enterprise: from stealing serverside data to infecting users with malware. Hackers are beginning to recognize this new playground and are quicklyadding JavaScript exploitation tools to their Web attack arsenal.
Bastian Ike, developer at AOE, talks about Application Security: How security issues develop, and how they are found, exploited and can be mitigated. Security issues usually develop due to assumptions on certain behavior, bugs and just missing knowledge about what is actually possible, and how these bugs can be exploited eventually. Bastian shows how these issues develop, and how attackers utilize and combine bugs to eventually exploit systems and elevate privileges. Bastian also shows how we can mitigate security issues and how to spot them in our code.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
