    A Follow-up on POODLE and SSL 3.0
    November 21, 2014 by Bruce Morton (Entrust) Attack Encryption Google IETF Mozilla OpenSSL SSL 3.0 SSL/TLS TLS 1.0 TLS 1.1 TLS 1.3 Vulnerability
    In October 2014, Google announced POODLE, an SSL 3.0 protocol attack. To bring you up to speed, the SSL/TLS protocol is the most important and popular security protocol on the Internet. The Secure Sockets Layer (SSL) protocol was developed by Netscape. They quickly moved from SSL 1.0 to 2.0 and finalized with SSL 3.0 in 1996. This protocol was then picked up by the IETF, who released it under the name of Transport Layer Security (TLS).

    Extra Trips are for Frequent Flyers, Not SSL/TLS Performance

    TLS is quickly becoming a de facto requirement for every website due to increased concerns about spying and Google’s recent move to use HTTPS as a factor in search engine ranking. In a recent article we explained how HSTS helps website operators to ensure that their site is always using TLS, but now we want to ensure that your performance isn’t sacrificed in the name of enhanced security. While the myth that TLS slows down a website has been debunked, some basic settings can make a site using TLS even faster.

    Secure Your Website with HSTS
    October 8, 2014 by Bruce Morton (Entrust) Attack Chrome Encryption Firefox Google HSTS Policy SSL/TLS
    Is your website secure? One thing to consider is securing your website with HTTP Strict Transport Security (HSTS). Implementation of HSTS is an extension of the Always-On SSL policy. For each website you want to protect with HSTS, you must first deploy an SSL/TLS certificate (if you haven’t already), and configure that website to be accessible only via HTTPS, not via HTTP. Then you convey to HSTS-enabled browsers that your site is only available with HTTPS, by sending the HSTS header value.

    Google Plans to Deprecate SHA-1 Certificates – Updated
    September 24, 2014 by CA Security Council Announcement Attack CASC Chrome Code Signing Google Microsoft Policy SHA1 SSL/TLS
    UPDATED September 23, 2014: The following blog post has been updated with action taken in recent weeks, as well as to reflect helpful user comments left on our August 28 blog post on this topic. On August 19, Google announced a new policy that accelerates the deprecation of SHA-1 certificates, potentially causing websites using SHA-1 certificates to display warnings in the near future. While keeping with an earlier Microsoft announcement to accept SHA-1 certificates with an expiration date before Jan.

    On August 19, Google announced a new policy that accelerates the deprecation of SHA-1 certificates, potentially causing websites using SHA-1 certificates to display warnings in the near future. With the change, Chrome 39 will show a warning for sites that have a SHA-1 certificate expiring in 2016 and require a click through warning for sites with a SHA-1 certificate expiring in 2017 or later. This proposal is scheduled for Chrome 39, which could be released as early as 12 weeks from now.

    Google to Give Priority Ranking to SSL Enabled Sites
    August 21, 2014 by Chris Bailey (Entrust) Announcement Google SSL/TLS
    Google’s announcement that it will give priority ranking to SSL enabled sites is a key milestone for increased use of SSL on the Internet. Google announced a change to its ranking algorithm to include use of SSL on the site as a “very lightweight [positive] signal”. Although, this might not have an immediate impact to website owners/operators that are not currently using SSL, this is still an important signal indicating everyone should be prepared to encrypt all their websites if they want to remain relevant.

    Who Sets the Rules Governing Certification Authorities?

    Every time something positive is published about SSL and encryption,such as Google’s recent decision making use of https encryption a favorable rating factor for a website, or negative, such as the Heartbleed issue – bloggers and others always post questions about public Certification Authorities (CAs), including general questions on who sets the rules that govern CAs. Some bloggers seem to assume there are no rules or standards, and that CAs can operate without any requirements or limitations at all — that’s incorrect.

    In the Wake of Unauthorized Certificate Issuance by the Indian CA NIC, can Government CAs Still be Considered “Trusted Third Parties”?
    July 24, 2014 by Ben Wilson CA/Browser Forum CAA CASC Chrome ETSI Firefox Google Microsoft Mis-issued Mozilla OCSP PKI Policy Revocation SSL/TLS Trust List WebTrust
    Short answer: Government CAs can still be considered “trusted third parties,” provided that they follow the rules applicable to commercial CAs. Introduction On July 8 Google announced that it had discovered several unauthorized Google certificates issued by the National Informatics Centre of India. It noted that the Indian government CA’s certificates were in the Microsoft Root Store and used by programs on the Windows platform. The Firefox browser on Windows uses its own root store and didn’t have these CA certificates.

    CASC Heartbleed Response

    The recent Heartbleed issue has reawakened interest in SSL certificate revocation (see Adam Langley’s blog, Larry Seltzer’s articles here and here, and Steve Gibson’s web pages) Several years ago, the CA Browser Forum convened a special Revocation Working Group to explore issues and solutions. Leading CAs were actively involved in that group, and many of them invested in moving their OCSP responders to high-performance, high-availability Content Delivery Networks (CDNs) to respond to browser vendors’ requests for increased performance and reliability.

    Revocation – A Cure For the Common Heartbleed
    April 28, 2014 by Jeremy Rowley Attack CASC Chrome CRL Google Identity OCSP Revocation SSL/TLS
    The Heartbleed bug spurred server administrators worldwide to work closely with Certification Authorities (CAs) in rekeying and reissuing potentially vulnerable SSL certificates. Part of this effort included revoking existing certificates used on vulnerable servers to ensure obtained private keys are not later used in a man-in-the-middle attack against the website. Unfortunately, in recent days, certain news reports and blogs addressing certificate revocation and checking for revoked certificates online have failed to discuss the benefits of revocation, instead focusing on the minority of circumstances where widely deployed revocation is not perfect.
