Root Causes: A PKI and Security Podcast

In this episode we explain the fundamentals of cookies and why, despite their obvious benefits, they present troublesome privacy concerns. We discuss the many ways web users can be tracked including cross-site cookies, tracking pixels, and browser fingerprinting.

In this third episode in our series on SSH keys, we identify the six main benefits of SSH certificates and how they mitigate the problems with SSH identified in earlier episodes.

Despite the similarity in their names, in the world of digital certificates a Relying Party and a Certificate Consumer are very different things. In this episode we define the four main roles in the public trust ecosystem: CA, Subscriber, Certificate Consumer, and Relying Party, with real-world examples.

In this follow-on to our earlier episode explaining SSH keys, we discuss the five problems SSH keys present to organizations using them. And we give a peek at how to solve these problems.

Vendor consolidation is an important topic in IT security. As the scope and variety of threats continues to increase, we have seen a proliferation of point solutions and features, and a resulting desire to reduce that vendor footprint or at least facilitate using them together. In this episode we discuss this trend and how it specifically affects PKI and digital certificates.

Attackers are using CT logs to identify brand new WordPress sites and install malware before upcoming security measures are in place. This attack is novel in how it exploits Certificate Transparency information to identify likely targets. In this episode we explain what is happening and why it's noteworthy.

SSH (Secure Shell) keys are ubiquitous for authenticated access to Linux systems. In this first of three episodes we explain what these keys are and how they're used.

"Passwordless" is a hot term in the industry, and as a result many technology vendors are attaching their solutions to this term. In this episode we clarify the difference between OTP services and passwordless authentication.

New proposed legislation in the US House of Representatives mandates that federal agencies must begin preparation for using the new quantum resistant cryptographic algorithms selected by NIST. This represents a major development in building a quantum safe digital world. In this episode we explain the proposed legislation and it's consequences.

Every technology space has its jargon. In this episode we go over some of the interesting, ambiguous, or amusing terms that are specific to the PKI and digital certificates industry.

In March the LAPSIS$ hacking group convincingly announced a breach of Okta systems, potentially exposing Okta customers to additional compromise. Despite Okta's initial statements to the contrary, it ultimately turned out that up to 366 Okta customers may be affected. Our hosts walk through the events of the attack, how it unfolded over time, and how this breach was revealed.

One of the foundational tools for monitoring and understanding public SSL certificates is crt.sh, created and maintained by Sectigo's own Rob Stradling. In this episode our hosts explain what crt.sh does and why it is so popular among SSL industry watchers.

Organizations seeking to use passwordless authentication frequently must deal with legacy systems that cannot support this scheme. In this episode we explain why that occurs and detail the steps organizations can take to mitigate the effect of legacy systems.

A recent FBI warning cautions organizations about exploits based on misconfigured DUO MFA, which exploits weaknesses in Active Directory to provision credentials on DUO for malicious parties. This is an unusual story in several ways, including the fact that the exploit is based on a configuration error and that it's specific to a single, popular SaaS offering. Our hosts explain this exploit and wh...

In this episode we describe a recent phishing campaign noteworthy for its scale, encompassing a total of 600 unique domains. We discuss the implications of a campaign of this scale and high level of organization.

On April 1 new root program requirements from Apple for S/MIME certificates go into effect, including a limitation of the allowable term to three years. This is contrary to Apple's stated intentions last year. In this episode the explain this change in policy and what certificate users can expect for the future.

Wildcard and multi-domain certificates have traditionally made administration easier for IT departments. In this episode we weigh the degree to which Certificate Lifecycle Management (CLM) renders these benefits obsolete and if these certificate types continue to be worth the increased risk they carry.

Microsoft has deprecated support for the popular sysadmin tool WMIC. Join our hosts as they explain the security reasons behind this development and broader lessons we can learn.

For any Certificate Lifecycle Management platform to succeed, effective deployment is essential. Our hosts are joined by Sectigo SVP of Global Sales Jennifer Binet who describes the optimal onboarding process, step by step. Jennifer discusses adding use cases over time, streamlining the contracting process, and getting to full automation for all certificates.

A major automobile manufacturer recently had a problem where its infotainment systems were permanently "bricked" by a flaw in local HD radio broadcasts. Our hosts describe what happened and explore the lessons we can learn from this incident.

Gartner analyst David Mahdi recently left the analyst space for Sectigo. In this episode he joins our hosts to explain the reasons for his optimism about digital trust, including NFTs, Web3, blockchain, PKI, and Zero Trust.

Web3 refers to the concept that online content can be attributed to specific known publishers, regardless of web site or online channel. In this episode we discuss the fundamentals of Web3, including self-signing protocols, authorization of content, blockchain, definitive authorship, consensus algorithms, and meat from space.

Secure online collaboration poses logistical and technical challenges under the best of circumstances. Now imagine you have no designated IT staff, no designated hardware, a small budget, and remote participants who are not deeply technical. In this episode Jason Soroko explains how he was able to quickly and easily create an encrypted communications mesh for use by him and his collaboration team.

In previous episodes we have defined passwordless identity authentication. In this episode our hosts explain PKI's specific role in passwordless authentication, along the way clarifying the difference between password-masking and true passwordless technologies.

Credential vaults are necessary for secure and functional secrets management for automated systems like DevOps or Robotic Process Automation (RPA). This episode explains how credential vaults work and details their benefits.
