Root Causes: A PKI and Security Podcast

90-day maximum term for SSL certificates is coming. In this episode expert guest Henry Lam details his four-point checklist for preparing enterprises for these shorter-lived certificates.

In our recent episode 300 we discussed Chrome's upcoming removal of the lock icon from its interface. In this follow up, we catch the listener up on Chrome's longstanding program to minimize the URL in its interface, even to the point of contemplating removing the address bar entirely.

Resulting from a recent ransomware attack, a private key from Intel has been exposed, affecting more than a hundred OEM components and an unknown number of end user products. We explain what happened and its possible implications.

This podcast frequently discusses the concepts of certificate automation and Certificate Lifecycle Management (CLM). In this episode we discuss how CLM does not always entail automation and vice versa -- along with where this distinction occurs and why it matters.

Google Chrome has announced that it will eliminate the lock icon in September. We explain what Google will be doing, its stated rationale, and the pros and cons of this decision.

The 2023 RSA Conference just concluded. This week Tim recaps what he saw at the show and how it reflects on security industry trends. Our hosts discuss Zero Trust, PQC, blockchain, artificial intelligence, post-COVID tradeshow behavior, and more.

The Google Chrome root store has communicated its plans for promoting automation. In this episode we explain Chrome's public plans for this initiative, which is anchored around ACME.

A recent outage in the Starlink internet service was caused by an unexpected certificate expiration. We discuss this ongoing problem and how 90-day maximum certificate term will exacerbate it.

The CA/Browser Forum guidelines contain many prescribed requirements, with language containing the word SHOULD or MUST. In this episode we explain the specifying power of these two words, why they are used, and what they signal about the intent behind a guideline and how the rules might evolve.

A large, public criminal marketplace for stolen logins and other information was rolled up by law enforcement across seventeen countries. Genesis Marketplace offered not only traditional login credentials but also associated data needed to defeat MFA.

The Root Causes podcast has received a Webby Honoree award. Jason and Tim briefly celebrate and discuss the challenge of operating a niche, homemade podcast while being directly compared to professionally produced podcasts on mainstream topics from media companies. Plus, Tim's new Root Causes t-shirt.

Certbot is an important part of the ACME standard. This open source tool makes it easier for many IT administrators to use ACME to automate provisioning and installation of SSL / TLS certificates.

As the industry explores the expected consequences of 90-day maximum term for SSL / TLS certificates, some are wondering if the allowed validation data reuse period stands to go down also. We explain today's data reuse rules and what the evidence indicates will be required for both domain control validation (DCV) and organization information validation.

We discuss how Certificate Lifecycle Management (CLM) interacts with Security Incident and Event Management (SIEM). The certificate world is chock full of events such as renewals, revocations, admin logins, and provisioning and removal of employee access. We talk about expected behaviors in the CLM and monitoring them.

In this episode we define Qualified Government Information Source (QGIS) and Qualified Independent Information Source (QIIS), which are critical to CABF-compliant organization validation. We explain how they fit into validation and the criteria for a reliable information source.

In this episode we dig into an emerging idea, which is the cryptographic center of excellence. We discuss how such a center of excellence would work and the benefits it can bring to an enterprise.

In this episode we are joined by Atsushi Yamada, CEO of ISARA. He explains how ISARA has put its patents on hybrid certificates into the public domain and why. We explain the role of hybrid certificates in PQC and ongoing crypto agility.

In this episode we describe an incident in which a GoDaddy breach exposed customer private keys. We explain the expectations surrounding private key exposure and get into the interesting question of when an incident is or is not part of a large company's CA business.

A new White House cybersecurity initiative specifically calls out digital identity and post quantum cryptography (PQC) among its focal areas. We discuss what it says and the potential implications.

In our ongoing exploration of the security implications of AI, in this episode we examine the suitability of ChatGPT as a malware-writing tool and possible future directions for AI in software creation.

The Google Chrome root program recently announced its intention to reduce the maximum term for public SSL certificates to 90 days. In this episode we explain this announcement and its implications and speculate on timing for this reduction.

In our episode 281 we reported on Google's proposal for optional OCSP. In this episode we correct some of our earlier reporting in that episode, including the use of CRL and the removal of any revocation requirement for SSL certificates of not more than ten days in term.

Repeat guest Bruno Couillard of Crypto4A joins us to explain where Hardware Secure Modules (HSMs) fit into the world of PQC. We discuss the issues surrounding how HSMs will work with post quantum algorithms and hybrid certificates and the process (and timelines) for defining how HSMs will incorporate PQC.

In response to concerns about OCSP and privacy, Google has proposed removing the requirement for OCSP revocation checking for public SSL certificates meeting certain specific conditions. In this episode we go into the details of this proposal.

Recent news reports might suggest that an AI-enhanced side attack has defeated the CRYSTALS-Kyber PQC algorithm. In this episode we clarify that Kyber has not been defeated to date and exactly what did occur. We define side channel attack, discuss the broader implications of this attack, and speculate on what would happen if Kyber actually were broken.
