Presented at the Atlanta Web Performance Meetup Group on June 2014, Billy Hoffman from Zoompf shows how to improve the performance of your website using SPDY and SSL and discusses SSL issues such as Heartbleed and CRIME
Many websites — from Wikipedia to Reddit to the Washington Post — are encrypting all of their web traffic to protect their readers' privacy by using SSL certificates are directing their traffic over HTTPS.
Besides the obvious security advantages, webmasters have another reason: Google is using HTTPS as a ranking signal.
At this meetup, we'll talk about what this all means (benefits, downsides) and problems encountered moving to HTTPS (and how they solved them).

RFC 7540 was ratified over 2 years ago and, today, all major browsers, servers, and CDNs support the next generation of HTTP. Just over a year ago, at Velocity, we discussed the protocol, looked at some real world implications of its deployment and use, and what realistic expectations we should have from its use. Now that adoption is ramped up and the protocol is being regularly used on the Internet, it's a good time to revisit the protocol and its deployment. Has it evolved? Have we learned anything? Are all the features providing the benefits we were expecting? What's next?In this session, we'll review protocol basics and try to answer some of these questions based on real-world use of it. We'll dig into the core features like interaction with TCP, server push, priorities and dependencies, and HPACK. We'll look at these features through the lens of experience and see if good practice patterns have emerged. We'll also review available tools and discuss what protocol enhancements are in the near and not-so-near horizon.

The SSL Problem and How to Deploy SHA2 CertificatesGabriella Davis
Two years ago enabling your site with SSL was a simple affair, buy a certificate or create your own, install it, then just remember to renew it every couple of years. Then, suddenly security holes are being found in SSL virtually every month , popular browsers stop connecting to your site to protect themselves, and you’re continually being told your users data is at risk. In this session we will discuss how it all went wrong and can go wrong again, then go through each step of requesting, generating and deploying a 4096 SHA-2 certificate to use in a keyfile by Domino, IBM Connections, IBM Sametime and other WebSphere products. If you work with these IBM products and need to secure them with confidence this session will show you how!

The document discusses SPDY, an evolution of HTTP developed by Google since 2009 that aims to speed up web content delivery. SPDY utilizes a single TCP connection more efficiently through multiplexing and other techniques. It allows for faster page loads, often around 39-55% faster than HTTP. While SPDY adoption is growing, with support in Chrome, Firefox, and Amazon Silk, widespread implementation by servers is still limited. SPDY is expected to influence the development of HTTP 2.0.
HTTPS presentation at Port80 Sydney meetup March 2016Jason Stangroome
HTTPS has become increasingly important for security and user experience. The document discusses several reasons for using HTTPS, including that 42% of the top 1 million websites have adopted it in the last 6 years. It covers topics like SSL/TLS protocols, certificate validation, HTTP Strict Transport Security, and Let's Encrypt which provides free SSL certificates to help websites transition to HTTPS. Overall it promotes the benefits of HTTPS for users, search engines and the continued improvement and standardization of encryption on the web.
SPDY is an experimental protocol developed by Google that sits on top of TCP and SSL to make web browsing faster. It addresses problems with how HTTP 1.1 handles multiple object downloads from modern websites by allowing for header compression, multiple simultaneous requests over a single connection, and server push capabilities. While browser and server support is still developing, using a SPDY gateway can provide speed improvements without requiring changes to existing web applications.

note: this talk was co-presented by me and Luís Grangeia (www.slideshare.net/lgrangeia)
SSL was developed in 1994 to secure communications between web browsers and servers. It uses public key cryptography and X.509 certificates to authenticate peers and encrypt data in transit. However, the current public key infrastructure (PKI) model that underpins SSL has several flaws, including being controlled by a small number of certificate authorities, making it vulnerable to hacks and insider threats. Some propose decentralizing trust decisions so that individuals, rather than centralized authorities, ultimately determine what is trusted. Others are working on alternative approaches like certificate pinning to avoid relying solely on the existing PKI model. Overall, there is recognition that the current system for establishing trust in SSL/TLS needs improvement.
1086: The SSL Problem and How to Deploy SHA2 Certificates (with Mark Myers)Gabriella Davis
This document discusses deploying SHA2 certificates and the SSL problem. It begins with introductions of the presenters. It then provides background on encryption, certificates, and common acronyms related to security like SSL, TLS, HTTPS. The document outlines several past security vulnerabilities like POODLE, Heartbleed, and discusses solutions deployed. It then provides step-by-step instructions for creating certificates using OpenSSL and deploying them for Domino and WebSphere servers.
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.
The document discusses SPDY and HTTP/2, which aim to improve upon HTTP/1.1 by allowing multiple requests to be sent concurrently over a single TCP connection through header compression and multiplexing. It notes that SPDY is now supported by major browsers but not Internet Explorer, while HTTP/2 is still not widely adopted. The document also describes how protocols like NPN and ALPN enable negotiation of the transport layer and encryption ensures security for intermediaries.
SSL Checklist for Pentesters (BSides MCR 2014)Jerome Smith
This document provides a summary of checks that a pentester should perform when evaluating the security of SSL/TLS implementations. It discusses checking for support of outdated and insecure protocols like SSLv2 and SSLv3. It also recommends validating support for newer, more secure versions like TLSv1.1 and TLSv1.2. The document outlines steps to check for vulnerabilities like Heartbleed, BEAST, and CRIME. It also provides guidance on evaluating certificate validity, cipher suites, and renegotiation support. Web application considerations like mixed content and HTTP Strict Transport Security are also covered at a high level. The presenter provides these checks and recommendations from the perspective of a pentester to identify potential issues to consider reporting

How the SSL/TLS protocol works (very briefly) How to use HTTPSwhj76337
1. HTTPS provides encryption for web traffic but has integration challenges with browsers. The lock icon is meant to indicate encryption but does not always accurately represent the security of a page.
2. Problems include sites initially loading over HTTP and then switching to HTTPS, certificates that do not clearly match the domain, and pages that load mixed encrypted and unencrypted content which can enable attacks.
3. Users often ignore or are confused by invalid certificate warnings, allowing man-in-the-middle attacks. The lock icon and browser interfaces could be improved to better convey security and privacy.

• Web server is listening on SSL port
• Web server understands SSL
• Web server knows which site you want
– Shared Hosting and SNI
21. X.509 Cert: Is it Trusted?
• Do I trust the issuer?
– If not, was it signed by someone I trust?
• Has it been revoked?
– CRL lists
– Online Certificate Status Protocol (OCSP)
22. Agreeing to Use SPDY
• Client tells server it supports SPDY
• Server tells client it supports SPDY
• Client sends SPDY over SSL
• Else, falls back to HTTP over SSL
24. Announcing SPDY support in the

29. The SSL Tarpits
• SSL handshake requires 2 round trips
• Certificates can be large
• Certificates need to be validated
• Keys can be too large
• Algorithms can be slow
• Revocation
30. The SSL Handshake is Costly!

35. False Start: Not Gone
• “The Failure of False Start”
• Chrome still does it!
– Desktop and mobile
• Any server that supports NPN! (with
forward secure)
– Any server with SPDY support…
– Or SSL + NPN, but only announces HTTP/1.1!
41. Cipher Order/Choice Matters
• RC4 is the best
• Unless on a
machine with AES-
NI
– Intel i7, Xeons,
some AMD
– Not most virtual
machines!!!
• First match wins
http://zombe.es/post/4078724716
46. SPDY Optimization
• SPDY only works over SSL
• Ensure that all your traffic if over SSL
• HTTP 301 direct for http: to https:
– Add a cache-control header!
• HTTP Strict Transport Security (HSTS)
– Like the browser’s cache, but for protocol
access. Make (semi) far future
– Wide support (>90% of SPDY capable
browsers)
47. Avoid These Optimizations
• Domain Sharding
– Hack to request multiplexing, not needed
– Hurts SPDY by spreading requests out
• JavaScript CDNs
– These are a horrible blight on the web!

52. SSL/SPDY Optimization Check List
• Website responds over SSL/443
• Website has NPN extension (even without
SPDY for False Start)
• X.509 certificate is valid
• X.509 chain is short
• SSL Asymmetric keys are <= 2048
• Cipher is fast! (RC-4, AES-128 if supports
dedicated instructions)
53. SSL/SPDY Optimization Check List
• SSL session resumption is enabled (both
identifiers and tickets)
• No SSL compression
• Website is using latest version of SPDY
• HTTP permanently (301) redirects to
HTTPS (including cache header)
• HTTPS sends HTTP Strict Transport
Security header
