The HTML5 WebSocket API allows for true full-duplex communication between a client and server. It uses the WebSocket protocol which provides a standardized way for the client to "upgrade" an HTTP connection to a WebSocket connection, allowing for messages to be sent in either direction at any time with very little overhead. This enables real-time applications that were previously difficult to achieve with traditional HTTP requests. Common server implementations include Kaazing WebSocket Gateway, Jetty, and Node.js. The JavaScript API provides an easy way for clients to connect, send, and receive messages via a WebSocket connection.

COMET is an upcoming method for delivering real-time interaction to a website by using server-push technologies. At the Snow Sprint 2008 Jean-Nicolas Bes and Ramon Bartl worked on making COMET work for the Open Source CMS Plone. This is their presentation from the final sprint summary.

To protect data integrity and identify the source, HTTPS uses symmetric and asymmetric encryption during exchanges. Certificate Authorities issue trusted certificates, though some have concerns about centralized control. Sysadmins can enable HTTPS on servers through protocols like TLS and cipher suites. Developers ensure mixed content and cookies are properly secured. While some older browsers have compatibility issues, HTTPS is becoming essential for privacy, SEO, and new technologies. OVH helps with free SSL certificates and gateways to simplify HTTPS implementation.

This document discusses using Capistrano and Magento 2 Capistrano to automate deployments of Magento 2 projects. Capistrano is a framework that allows deploying code automatically through SSH.

The document covers installing and configuring Capistrano, customizing deployment tasks, and deploying to multiple servers. It also addresses questions about config files and restarting PHP-FPM.

WebSocket is a new web technology that provides bidirectional communication between a client and server over a TCP connection. It aims to overcome limitations of Ajax techniques like long polling and streaming that used HTTP. The WebSocket API was standardized by the W3C and IETF and is supported in HTML5 browsers through native JavaScript. It enables new types of web applications by facilitating real-time data transfer and interactive experiences.

In this talk, we'll break down how one can exploit an ecosystem that enables management, querying, processing, and storage of, yes you guessed it, copious amounts of data. Hadoop and its many friends have been making their way into companies analyzing (sometimes, after massively collecting...) such data for years now, but they also make it easy to find organizations deploying things internally with security either off by default or otherwise exposed to various critical misconfigurations and access control issues. If you're running engagements, this should also give you a headstart on what to look for, how to attack networks where these products are running along with a few good ways to make them more defendable. Because if you want to defend well, you need to optimize towards mitigating actual risk vs theoretical, and there's no better way to determine if attacks are real than trying them out yourself. Let's say you just want to better understand how to shell out on servers running Apache Cassandra, Drill, Mesos... well, it may add a few pages to your playbook. (FYI this is the version of the slides without a conference template-- hopefully NoConName will share the templated version online as well)

This document discusses PHP shells, which are malicious files containing PHP functions used to run arbitrary commands supplied by attackers. PHP shells are usually delivered through exploited third-party plugins and are a threat as they allow attackers to compromise servers. The document provides tips on defending against PHP shells such as sanitizing user input, restricting PHP usage, and removing any shell files found on servers.

https://cfp.nonamecon.org/nnc2020/talk/9LMJAH/ For many years, injection-based vulnerabilities such as XSS and SQL-injection have dominated the web security landscape. However, as browsers and applications are becoming increasingly complex, new vulnerability classes surface. One of these new-kids-on-the-block is XSLeaks, a vulnerability class that exploit side-channel leaks in the browser to extract information across origins. In this presentation, I will describe the various types of leaks in different browser features and the network layer, and discuss how these issues can be exploited to extract sensitive information from an unwitting victim. Furthermore, the talk will cover the numerous (new) defences that need to be adopted in order to safeguard web applications (SameSite cookies, COOP, COEP, ...), and their potential shortcomings. Finally, we will take a peak into the future, and discuss how XSLeaks will likely evolve in the coming months and years.

The document discusses four main problems with the traditional approach to application security: 1. Security testing creates an asymmetric arms race between testers and attackers. Traditional end-of-cycle penetration tests only provide minimal security. 2. Applications often incorporate outsourced, open source, or third party code that may contain vulnerabilities. Dependency issues are rarely tested. 3. It is difficult to manage vulnerabilities at scale across a large number of applications and reports from different testers. 4. Security issues overwhelm developers with too much information, creating "white noise" and prioritizing compliance over risk. Contextualizing risk is important.

This document provides a checklist of 42 documents needed for ISO 27001:2013 certification. It lists each document name, the relevant ISO 27001 clauses, and whether the document is mandatory.

La capacità di rispondere in poche frazioni di secondo alle richieste degli utenti - indipendentemente dal loro numero - è un fattore determinante per il successo dei servizi sul web. Secondo Amazon, bastano 100 millisecondi di latenza nella risposta per generare una perdita economica di circa l'1% sul fatturato [1]. In base alle statistiche di Google AdWords, inoltre, il 2015 ha sancito l’ufficiale superamento del numero di interazioni mobile rispetto a quelle desktop [2], con la conseguente riduzione della durata media delle sessioni di navigazione web. In uno scenario di questo tipo, la razionalizzazione dell’utilizzo delle risorse hardware e la capacità di scalare rispetto al numero di utenti sono fattori determinanti per il successo del business. In questo talk racconteremo la nostra esperienza di migrazione di soluzioni e-commerce di tipo enterprise in Magento da un’architettura basata su VM tradizionali ad una di tipo software-defined basata su Kubernetes, Flannel e Docker. Discuteremo, quindi, delle reali difficoltà da noi incontrate nel porting su container di soluzioni in produzione e daremo evidenza di come, alla fine di questo lungo viaggio, i nostri sforzi siano stati concretamente premiati dall’aumento di resilienza, affidabilità e automazione della soluzione finale. A supporto della conversazione, mostreremo i risultati dei benchmark da noi condotti per valutare la scalabilità della nuova architettura presentando delle evidenze delle reali capacità di Kubernetes come strumento di orchestrazione di servizi erogati in Docker container. Concluderemo l’intervento presentando il nostro progetto di distribuzione geografica dei nodi master di Kubernetes facendo uso di reti SD-WAN per garantire performance e continuità di servizio della soluzione.
