Hacking Your Way to Better Security - ZendCon 2016Colin O'Dell
This document discusses various web application security vulnerabilities like SQL injection and cross-site scripting (XSS) from the perspective of an attacker. It begins by introducing SQL injection and demonstrates how it can be used to extract hidden data like usernames and credit card numbers. It then covers XSS and how malicious scripts can be injected onto a page to hijack user sessions. Finally, it discusses ways to protect against these vulnerabilities like input filtering, output encoding, and prepared statements. The overall goal is to help understand common attacks and how to build more secure applications.
Web crawlers are programs that collect data, especially links, from websites to build indexes for search engines. They use reinforcement learning to make more intelligent decisions about where to search for related pages. Reinforcement learning provides rewards when relevant pages are found, guiding the crawler towards high long-term rewards. This improves searches by helping crawlers find important and trusted pages more effectively.
PHP is the most commonly used server-side programming and deployed more than 80% in web server all over the world. However, PHP is a 'grown' language rather than deliberately engineered, making writing insecure PHP applications far too easy and common. If you want to use PHP securely, then you should be aware of all its pitfalls.
PHP 7 provides major performance improvements for most applications. Key changes include breaking backward compatibility in some areas like removing alternative PHP tags, making multiple switch default cases a syntax error, and removing deprecated extensions. New features include the spaceship operator, anonymous classes, return type declarations, and group use declarations. Understanding how existing code may be impacted and changes needed helps migrate to PHP 7 and take advantage of its gains.
Introduction to NPM and building CLI Tools with Node.jsSuroor Wijdan
In this talk, we talked about NPM. Why is it so powerful and verticals where it is being used apart from Node.js. Also we go through the basic packages and how can we build a simple CLI tool with Node.js and publish it on NPM.
PHP stands for Hypertext Preprocessor and originated as a scripting tool that has become popular for web development due to being free and having frameworks to simplify development. Major sites using PHP include Twitter and Facebook. ASP stands for Active Server Pages and allows coding using any .NET supported language, increasing its popularity among .NET developers, as well as Microsoft's early domination of the browser market with Internet Explorer.
PHP was created in 1994 by Rasmus Lerdorf. It began as a simple scripting language for generating dynamic web pages and has grown over 20+ years to become one of the most popular web development languages. PHP 7 was released in December 2015 and brought major performance improvements through optimizations in the Zend engine. While some criticize PHP's design, others appreciate how easy it is to learn, install, and find work developing with PHP due to its large community and number of open source projects that use it.
PHP7 - The New Engine for old good trainXinchen Hui
PHP 7 provides major performance improvements over previous versions through a refactored engine. It focuses on optimizing core functions and data structures like ZVAL and HashTable to reduce CPU and memory overhead. Some key optimizations include using an Abstract Syntax Tree, improving integer handling, making function calls more efficient, and enhancing the memory manager. Benchmark tests show PHP 7 can be over 5 times faster than PHP 5 for simple tests and around 2 times faster for real-world applications like WordPress. The goal is to achieve a new level of PHP performance while maintaining 100% compatibility.
The document discusses PHP7 and how to optimize it for best performance. It notes that PHP7 is up to twice as fast as PHP5.6 and uses significantly less memory. It then provides several recommendations for further optimizing PHP7 performance, such as using Unix domain sockets, opcache file caching, profile guided optimization, and huge pages. Real-world benchmarks from companies show PHP7 provides 15-40% better performance.
For more than a decade, organizations trust in network perimeter protection such as firewalls or intrusion prevention systems to protect their IT infrastructures from the internet threats. However, traditional network security protection may not be sufficient to safeguard from the new threats targetting security flaws in web servers and web applications. In order to defend the threats related to these services and applications, it is essential to understand the risks commonly found in web applications.
This presentation explains the needs of application security as the last line of defense, common web application risks and security measures need to be implemented alongside the development of web applications.
The document discusses performance improvements in PHP7 compared to PHP5. The key improvement is the introduction of a just-in-time compiler (JIT) that compiles PHP code to machine code during execution. This was made possible by redesigning the zval internal data structure to reduce memory usage and optimize for JIT compilation. The new zval structure stores basic types directly instead of using references, and external structures are used for complex types like strings and arrays.
Hacking Your Way to Better Security - PHP South Africa 2016Colin O'Dell
This talk educates developers on common security vulnerabilities, how they are exploited, and how to protect against them. We'll explore several of the OWASP Top 10 attack vectors like SQL injection, XSS, CSRF, and more. Each topic will be approached from the perspective of an attacker to see how these vulnerabilities are detected and exploited using several realistic examples. We'll then apply this knowledge to see how web applications can be secured against such vulnerabilities.
This document discusses adopting a secure software development strategy at Kiatnakin Bank. It recommends starting with a goal like the OWASP Top 10 controls, establishing an application security team, processes like code reviews and testing, baseline frameworks and guidelines, introducing security design concepts, and setting security checkpoints. The presentation emphasizes building knowledge, leading change, and getting management support to successfully adopt secure development practices.
Secure code review is probably the most effective technique to identify security bugs early in the system development lifecycle.
When used together with automated and manual penetration testing, code review can significantly increase the cost effectiveness of an application security verification effort. This presentation explain how can we start secure code review effectively.

some steps I used in creating a nearly automatic workflow of getting
pictures from my camera to his gallery using Perl.
PHP 7.1 includes several new features and performance improvements. Some key new features are nullable types for typehints, void return types, support for iterable pseudo-types, class constant visibility modifiers, and the ability to catch multiple exception types in a single catch block. PHP 7.1 also provides over a 10% performance improvement compared to previous versions, due to enhancements like type specific opcode handlers and a new type inference system.
Automating Your Workflow with Gulp.js - php[world] 2016Colin O'Dell
Gulp is a powerful utility for automating development workflows. Tasks are written using code, not configuration, enabling the easy creation of highly-custom and flexible automations. This talk introduces developers to the core concepts of gulp.js, and how to leverage it for new & existing projects. We’ll cover several examples of common tasks for managing CSS, JS and PHP, including: compiling Sass, minifying files, running PHP tests, checking code styles, ensuring legacy browser support & more.
