IETF 86 – Web PKI Working Group
March 21, 2013 by Bruce Morton (Entrust) CRL Google IETF OCSP PKI Policy Revocation SSL/TLS Web PKI
At the IETF 86 meeting in Orlando last week, there was a working group meeting discussing the operations of the Web PKI. At the previous IETF 85 meeting a birds-of-a-feather was held to discuss the purpose of having such a group. The result of the meeting was an established group with the charter that states purposes such as: Working group will work to improve the consistency of Web security behavior Address problems as seen by the end-users, certificate holders and CAs Describe how the Web PKI actually works Prepare documented deliverables as discussed below The meeting discussed the charter and the four following deliverables.
All You Need to Know About the RC4 Encryption Scheme
March 14, 2013 by Rick Andrews Attack CASC Encryption RC4 RSA SSL/TLS Vulnerability
The latest published attacks target specific algorithms used within SSL/TLS. Those algorithms are used when a client connects to a server via SSL/TLS; they’re not used when a Certificate Authority signs a certificate. The attacks demonstrate potential weaknesses in the use of the algorithms. While interesting, the attacks don’t represent an immediate practical threat to users of SSL/TLS (including online banking, e-commerce, social networking, etc.). Such attacks require an attacker to run malicious software on a user’s computer which would connect to a particular web site and send the same message over and over again many times.
The Importance of Revocation Checking Part 2: A Real World Example
March 11, 2013 by Wayne Thayer Attack Code Signing CRL Encryption Identity Malware OCSP Revocation SSL/TLS
Just last week, a new security incident related to certificate revocation checking made headlines. It was discovered that a legitimate website was hosting a malicious Java application that installed malware on the computers of people who visited the site. This comes after recent updates that introduced Security Level settings in Java, and then raised the default from Medium to High. At the high level, users are shown a warning before any unsigned Java code is executed.
The Importance of Checking for Certificate Revocation
March 9, 2013 by Rick Andrews Attack CRL Identity Malware MITM OCSP Revocation SSL/TLS
Certificates are typically valid for one to three years, and during that time it’s possible that the web site owner or the CA realizes that end users should not trust the certificate. There are several cases in which this might happen, including these: The web site owner ceases doing business, no longer owns the domain name used in the certificate, has changed their organization name, or wishes to shut down the web server.
RSA Recap – Securing Your Site
March 8, 2013 by Ben Wilson BEAST CASC Encryption Firefox Hash Function HSTS OpenSSL Policy RSA SSL/TLS TLS 1.1 TLS 1.2 Vulnerability
At RSA last week a few of us participated in panel discussions that focused on SSL/TLS. During the panel that I moderated on Friday, one theme we addressed was secure server configuration. One of CASC’s goals is to help harden existing SSL/TLS implementations against vulnerabilities—because most SSL/TLS exploits arise from suboptimal website configurations. These vulnerabilities and attacks can be mitigated or even eliminated with proper server configuration and good website design.
CASC Happenings at RSA
February 25, 2013 by CA Security Council Attack CASC Identity PKI RSA SSL/TLS
We are excited to have members of the CASC attending and speaking at this year’s RSA Conference. The events and panels will cover various topics that revolve around the security of the Internet and CAs as a whole. You can follow the CASC on Twitter for more information and news at @CertCouncil, as well as see some of the presentations after the events on our SlideShare page. Please join us for the following CASC member events:
OCSP Stapling: Improved Performance and Security, a Win-Win
February 14, 2013 by Jeremy Rowley CASC OCSP Revocation SSL/TLS
The launch of the CASC has given its members a unique platform through which we can educate users about online security and the best practices in utilizing SSL. That’s why we’ve decided to pair the group’s launch with a focused effort on OCSP stapling. Why OCSP stapling? For one, stapling is already supported by IIS and the newest versions of Apache and nginx. Although server software does not enable OCSP by default, servers can be re-configured with a little education.
Certificate Revocation and OCSP Stapling
February 14, 2013 by CA Security Council Attack CASC CRL IETF OCSP Revocation SSL/TLS
Revocation As a body of global CAs, the CA Security Council is committed to educating server administrators, end-users and other interested parties about SSL enhancements and best practices that can better protect everyone. An important initiative that can make a practical difference right now is addressing easily implemented improvements to certificate status services that handle revocation of invalid or expired certificates, specifically the implementation of OCSP stapling. What is certificate revocation?
World’s Leading Certificate Authorities Come Together to Advance Internet Security and the Trusted SSL Ecosystem
February 14, 2013 by CA Security Council CA/Browser Forum CASC CRL OCSP Revocation SSL/TLS
San Francisco, CA. – February 14, 2013 – Leading global certificate authorities announced the creation of the Certificate Authority Security Council (CASC), an advocacy group, committed to the exploration and promotion of best practices that advance the security of websites and online transactions. Through public education, collaboration, and advocacy, the CASC strives to improve understanding of critical policies and their potential impact on the internet infrastructure. Members of the CASC include Comodo, DigiCert, Entrust, GlobalSign, Go Daddy, Symantec, and Trend Micro.
February 14, 2013 by Robin Alden (Sectigo) Announcement CA/Browser Forum CASC SSL/TLS
Today marks an important day for internet security and future SSL enhancements, as the world’s seven largest publicly trusted Certificate Authorities are announcing the formation of the Certificate Authority Security Council. While leading CAs have worked together for years to address security challenges and meet them with evolving and increasingly strict standards and best practices through the CA/Browser Forum and other industry venues, we’ve lacked a union where we can come together and speak with a unified CA voice.
