    The purpose of this article

    The purpose of this article is to demonstrate why I believe browser-based UI for website identity can make the web safer for everyone. I explain in great detail, the reasons why the UI and UX didn’t work in the past. And what’s left is only making the problem worse instead of better.

    9 Common Myths About CAs

    Over the years misconceptions about CAs and the SSL infrastructure have arisen. Below is a list of common myths related to SSL and CAs.

    Myth #1: CAs are not regulated

    Fact: CAs are subject to various checks and balances, including third-party qualified audits through WebTrust or ETSI and strict criteria set forth by leading browsers, before they are accepted in browser root stores. Similarly, the CA/Browser Forum’s Baseline Requirements and Network Security Guidelines establish global standards for certificate issuance and CA controls that will soon be included in third-party auditing standards. Browsers are free to use these requirements to exclude non-compliant CAs from the root store.

    The Advantages of Short-Lived SSL Certificates for the Enterprise
    July 18, 2019 by Doug Beattie (GlobalSign) CRL Mozilla Revocation SSL/TLS Vulnerability

    Short validity period certificates are becoming ever more common to reduce the scope of data compromised if a server vulnerability is uncovered, such as HeartBleed.  Good security practice dictates changing keys on a regular basis, normally annually, but if you want to limit your exposure further, you can replace your certificates and underlying keys more frequently.

    Sandstorm is an open source server software that makes it easy to install web apps. In order to solve the problem of setting up DNS without too much complication, Sandstorm announced the release of Sandcats.io. Sandcats.io is a free DNS service which takes 120 seconds to go from an empty Linux virtual machine to a working personal server with a DNS name and HTTPS. The DNS service runs on the sandcats.io server while the “personal server” runs on each individual customers’ computers.

    What Are Subordinate CAs and Why Would You Want Your Own?

    Digital certificate and PKI adoption has changed quite a bit in recent years. Gone are the days where certificates were only synonymous with SSL/TLS; compliance drivers like stronger authentication requirements and digital signature regulations (e.g. eIDAS) have greatly expanded the role of PKI within the enterprise.

    As PKI usage has expanded, conversation has moved beyond just the number and type of certificates needed and onto deeper dialogue about custom PKI deployments. A large part of the conversation is around subordinate CAs, sometimes referred to as Issuing or Intermediate CAs, and why an organization might want their own. Let’s discuss.

    Looking Back at 2018

    2018 was an active year for SSL/TLS. We saw the SSL/TLS certificate validity period drop to 825-days and the mass deployment of Certificate Transparency (CT). TLS 1.3 protocol was finally completed and published; and Chrome status bar security indicators changing to remove “secure” and to concentrate on “not secure.” The CA/Browser Forum has been reformed, the London Protocol was announced and the nearly full distrust of Symantec SSL completed. Here are some details on some of the 2018 happenings in the SSL/TLS ecosystem.

    Looking Back at 2016

    Fortunately, 2016 was not a year full of SSL/TLS vulnerabilities. Although some researchers did prove old cryptography algorithms should be put out to pasture. The year showed the end of public-trusted SHA-1 SSL/TLS certificates. It also showed more transparency should be considered due to issues discovered with a few certification authorities (CAs). The great news is HTTPS is no longer the minority — after 20 years, connections using HTTPS has surpassed HTTP.

    Leading Certificate Authorities and Microsoft Introduce New Standards to Protect Consumers Online

    San Francisco –December 8, 2016 – the Certificate Authority Security Council (CASC), an advocacy group committed to the advancement web security, today announced the Code Signing Working Group has released new Minimum Requirements for Code Signing for use by all Certificate Authorities (CA). These requirements represent the first-ever standardized code signing guidelines. Code signing is the method of using a certificate-based digital signature to sign executables and scripts in order to verify the author’s identity and ensure that the code has not been changed or corrupted. Helping to verify software authenticity and avoid downloading malware and other malicious software is critical to protecting consumers’ online interactions. Microsoft is the first applications software vendor to adopt these guidelines, with others expected to follow.

    Minimum Requirements for Code Signing Certificates

    It is time for an update on the Baseline Requirements for Code Signing.

    First the bad news, the new standard was not approved by the CA/Browser Forum due to philosophical differences among some forum members who felt code signing was not in scope with the Forum’s charter.

    The good news is the document was created in a multi-stakeholder environment and substantially improves the current management processes. As such, it was decided to bring the document outside of the forum and finalize it as part of the CA Security Council. The CASC members and others will continue to enhance and manage the document. Microsoft also supports the document and has added the requirement to use the new standard for code signing certificates by February 1, 2017.

    Looking Back at 2015

    A number of new tactics proved 2015 was no exception to an active year defending against ever increasing security issues. Vendors found new and creative ways to provide vulnerabilities including the now popular man-in-the-middle (MitM) attacks.  MitM as well as a host of other new vulnerabilities caused browsers to rethink their security requirements.  This article gives a flashback of the exploits and industry changes from 2015 and looks ahead at the latest security requirements and how it impacts IT security teams.

    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.
