HTTPS: All you need to know

This document discusses the DANE protocol, which combines DNSSEC and TLS to provide both encryption and strong integrity protection for secure communication. It explains that while TLS provides encryption, DNSSEC provides integrity protection by allowing certificates to be stored and signed within DNS. This prevents man-in-the-middle attacks and ensures browsers receive the correct certificates. The document provides resources on DANE and urges developers, DNS providers and network operators to support it to improve security.

Squid Proxy Server on RHEL introduces Squid, a free and open-source proxy server software that provides caching, authentication, bandwidth management, and web filtering capabilities. It discusses configuring Squid on Red Hat Linux including installing packages, editing configuration files, starting services, and testing the proxy functionality. Browser and client settings are also covered to allow systems to route traffic through the Squid proxy server.

HTTPS is an encrypted version of HTTP that aims to secure communications over the internet. It uses SSL/TLS protocols to encrypt data transmitted between a client and server. This prevents sensitive information like passwords and credit cards from being accessed or altered by unauthorized parties when sent over the internet. HTTPS provides authentication of the server and encryption of data transmitted, addressing limitations of the unsecured HTTP protocol.

The document provides instructions for setting up an OpenVPN server to allow both Linux and Mac OS X clients to securely connect. It describes generating certificates and keys, configuring the OpenVPN server, and then configuring Linux and Mac OS X clients to connect to the server. The key steps are: 1) Generate certificates and keys on the server using the OpenVPN easy-rsa scripts. 2) Configure the OpenVPN server configuration file and required files. 3) Distribute client certificates to Linux and Mac clients and configure the clients. 4) Start the OpenVPN server and test connectivity between clients and the server network.

The document discusses proxies and caching. Proxies act as intermediaries between local networks and external networks like the Internet. They can improve performance by caching frequently requested web pages. Squid is an open source proxy caching server that operates by checking its cache for requested objects, retrieving objects from origin servers if needed, and storing cacheable objects in its local cache.

The Internet Public Key Infrastructure (PKIX) is broken, but several solutions exist to fix some of the issues around transport encryption with TLS and x509 certificates. This webinar will take a deeper look at two solutions: RFC 7672 “SMTP with DANE” and draft-ietf-uta-mta-sts “SMTP MTA Strict Transport Security (MTA-STS)”. What problems are solved with these solutions? What is needed to implement MTA-STS and SMTP-DANE? Is one solution preferable over the other, or should you deploy both?

This document provides an introduction to DNSSEC and DANE based security for TLS. It discusses how DANE uses DNSSEC-signed TLSA records to bind TLS certificates to domain names, solving problems with the traditional PKIX trust model. The document outlines how DANE works, how to create TLSA records, and how DANE can secure protocols like HTTPS, SMTP, and XMPP that currently rely on PKIX certificates. It also introduces the Bloodhound browser that includes DANE support to validate TLS connections using DNSSEC and DANE.

This presentation covers the current status of TLS 1.3 in the wolfSSL embedded TLS library (as of the time it was presented). It talks about the Draft status of TLS 1.3, middlebox compatibility, extensions, RSA-PSS negotiation and the specification's progress in the TLSWG (TLS Working Group). www.wolfssl.com www.wolfssl.com/tls13

The time of static or dynamically generated sites is long gone. Non-stop interaction with users is the new normal. However, polling with Ajax requests is processor intensive and cumbersome. Websockets allow you to interact with users in real-time without increasing system load. We'll go through the basics and see all the different options, illustrated with live examples of how and when to use it.

SSL and HTTPS configuration can be complex due to the involvement of multiple cryptographic protocols and standards. Many things can go wrong requiring updates to server configurations to support the latest protocols and address vulnerabilities. Proper configuration of certificates, encryption standards, hashes, and protocols is required to ensure a secure connection.

A web proxy is a server that acts as an intermediary for client requests to access resources from other servers. Squid is a commonly used open source web proxy caching server that improves performance by caching content and controlling bandwidth usage. It provides access logging and filtering capabilities. To install Squid, it is downloaded and configured on a Linux system. Access control lists (ACLs) are defined in the configuration file to restrict access based on source/destination IP addresses, domains, URLs, or time of day.

Our job might be to build web applications, but we can't build apps that rely on networking if we don't know how these networks and the big network that connects them all (this thing called the Internet) actually work. I'll walk through the basics of networking, then dive a lot deeper (from TCP/UDP to IPv4/6, source/destination ports, sockets, DNS and even BGP). Prepare for an eye-opener when you realize how much a typical app relies on all of these (and many more) working flawlessly... and how you can prepare your app for failure in the chain.

This document summarizes potential vulnerabilities in Adobe Flash Player 9 that could allow a malicious SWF file to bypass the same-origin policy and control a victim's web browser. It describes how the Flash Player Socket class could be used to perform port scanning or relay sockets without permission. It also explains how DNS spoofing could trick the Flash Player into granting a SWF file access to a different domain. An actual malware program called "FlashBot" is presented that leverages these techniques to turn infected browsers into a botnet to perform tasks instructed by a command and control server. Workarounds like disabling Flash or using a firewall are suggested to prevent exploitation.

The Security library in VisualWorks went through sweeping changes recently. Main change is replacing native smalltalk implementations of various cryptographic algorithms with pluggable interfaces to external libraries, but also a complete rewrite of the SSL implementation to support all current versions of the protocol (SSL3.0 & TLS 1.0, 1.1 and 1.2). Introducing dependencies on external libraries can complicate deployment, however the resulting pluggability of implementation and perfomance boost we're getting in exchange should more then pay off in terms of widening the scope of potential applications, where the purely native implementation was simply not acceptable. In this talk we will survey these changes and discuss their impact and backward compatibility implications.

This presentation, DEFEATING THE NETWORK SECURITY INFRASTRUCTURE v1.0.pdf, was made after some brainstorming with some friends. The techniques used are not new and the tools readily available for download. The purpose of the discussion however is to debate how internal enterprise resources might be (in)adversely exposed to the internet by in an insider using a combination of common techniques such as SSH and SSL.

This document provides an overview of HTTP including: - HTTP is a stateless protocol that does not require servers to retain user information across requests. - Popular HTTP proxy tools like Fiddler and Burp Suite can be used to inspect and debug HTTP traffic. - Key parts of HTTP include requests methods, response codes, headers for accepting content types, encoding, authentication, and more. - Common players that interact with HTTP include web servers, load balancers, caching servers, CDNs, and security tools.

This document discusses moving a website from HTTP to HTTPS. It explains that Google now ranks HTTPS URLs higher in search results and prefers HTTPS over HTTP. The document then discusses the specific steps taken to move FreshBooks' website to HTTPS, including enabling HTTP Strict Transport Security (HSTS) and TLS session resumption to improve performance. It also explains OCSP stapling to efficiently check certificate revocation status. Overall, the key steps outlined are enabling HSTS, TLS optimizations, and only using TLS from content delivery networks to origins when necessary.

The Reinvent 2016 conference hosted by Amazon Web Services included keynotes, over 400 sessions across 4 locations over 5 days. New services and updates were announced across compute, analytics, database, developer tools, artificial intelligence, monitoring, migration, mobile, containers, and lambda. Significant announcements included new instance types, elastic GPUs, IPv6 support for EC2, Athena for querying S3 data with SQL, Glue for data integration and transformations, and expanded capabilities for many existing services like Lambda, CloudFront, and Snowmobile for large data transfers.

The document discusses the future of software-defined storage in 3 years. It predicts that storage media will continue to advance with higher capacities and lower latencies using technologies like 3D NAND and NVDIMMs. Networking and interconnects like NVMe over Fabrics will allow disaggregated storage resources to be pooled and shared across servers. Software-defined storage platforms will evolve to provide common services for distributed data platforms beyond just block storage, with advanced data placement and policy controls to optimize different workloads.

Data centers house servers, routers, storage systems, and other networking equipment to provide information technology services like email, web hosting, and application hosting. They have large power needs and specialized cooling systems to handle the heat generated by servers. Benefits of data centers include economies of scale, security, and redundancy to minimize downtime. Data centers are classified into tiers based on their redundancy and availability, with tier 4 data centers achieving 99.995% uptime. While data centers require specialized knowledge and equipment, cloud computing offers similar services on-demand with no specialized expertise required.

HTTP/2 (or “H2” as the cool kids call it) has been ratified for months, and browsers already support or have committed to supporting the protocol. Everything we hear tells us that the new version of HTTP will provide significant performance benefits while requiring little to no change to our applications—all the problems with HTTP/1.x have seemingly been addressed; we no longer need the “hacks” that enabled us to circumvent them; and the Internet is about to be a happy place at last. But maybe we should put the pom-poms down for a minute. Deploying HTTP/2 may not be as easy as it seems since the protocol brings with it new complications and issues. Likewise, the new features the spec introduces may not work as seamlessly as we hope. Hooman Beheshti examines HTTP/2’s core features and how they relate to real-world conditions, discussing the positives, negatives, new caveats, and practical considerations for deploying HTTP/2. Topics include: The single-connection model and the impact of degraded network conditions on HTTP/2 versus HTTP/1 How server push interacts (or doesn’t) with modern browser caches What HTTP/2’s flow control mechanism means for server-to-client communication New considerations for deploying HPACK compression Difficulties in troubleshooting HTTP/2 communications, new tools, and new ways to use old tools
