Root Causes: A PKI and Security Podcast

Tim Callan and Jason Sorokosoundcloud.com
Digital certificate industry veterans Tim Callan and Jason Soroko explore the issues surrounding digital identity, PKI, and cryptographic connections in today's dynamic and evolving computing world. Best practices in digital certificates are continually under pressure from technology trends, new laws and regulations, cryptographic advances, and the evolution of our computing architectures to be more virtual, agile, ubiquitous, and cloud-based. Jason and Tim (and the occasional guest subject matter expert) will help you stay current on developments in this essential technology platform and to understand the whys and wherefores of popular Public Key Infrastructures.

Root Causes 119: What Is Crypto Agility?

Security industry insiders sometimes use the phrase "crypto agility." In this episode our hosts define crypto agility - or cryptographic agility. They explain why crypto agility is more important than ever, why the pace of cryptographic change is going up, and what certificate subscribers can do to improve their crypto agility.

Root Causes 117: Why Default Deny Matters to the CA/Browser Forum

This year the CA/Browser Forum has put considerable discussion into the concept of "default deny." It's a philosophy for how to interpret potential ambiguities in existing guidelines for public certificates, and how you land on the default-deny question can have a significant impact on how you interpret the rules. Join our hosts as they describe this debate and its potential impact on public certificates.

Root Causes 113: What Is Certificate Pinning?

Certificate pinning is the practice of coding software to demand the presence of a specific certificate brand or root in order to function correctly. Though once considered a legitimate security option, certificate pinning is widely discredited because it carries unacceptable certificate agility costs. Join our hosts as they explain what certificate pinning is, how it came about, and why nearly all developers should avoid certificate pinning today.

Root Causes 111: Secure Data Interconnects

Distributed data centers are extremely common in today's computing environments. Unencrypted replication of data across these centers leaves data open to theft. Nonetheless, existing systems and software leave that possibility open, and sometimes data replication occurs in the clear. Our hosts explain how this situation can come about and what to do about it.

Root Causes 109: Examining MFA Through Phone-based SMS

SMS-based one time password (OTP) is a very commonly used form of multi-factor authentication (MFA). That's because it's fast and inexpensive to roll out to users. Unfortunately it is deeply vulnerable to a set of well-defined attacks. In this episode our hosts explain why SMS MFA became so popular and how this outdated MFA scheme fails to provide the security expected by those who use it.

Root Causes 108: Why Do Certificates Expire?

Root expirations occasionally make headlines by breaking systems, but it's a fact that certificates are expiring every day, each a potential outage waiting to happen. So why do certificates expire in the first place? Join our hosts as they discuss the reasons for expiration, its advantages over other mechanisms like revocation, and the right amount of time for a certificate to last.

Root Causes 106: Massive Intermediate Certificate Distrust Is on the Way

A recently identified and widespread configuration error has created a situation where, with the wrong attack on certain public roots, certificates could become essentially unrevokable. As a consequence, 14 public CAs will have to revoke their OCSP certificates, many of which are also intermediates, and permanently discontinue use of their keys. That leaves millions of active TLS, S/MIME, code signing, and document signing certificates in need of immediate replacement or they will be distrusted....

Root Causes 100: OpenSSH Deprecates SHA-1

Once widely used, SHA-1 is considered insecure today and has been deprecated from the most common PKI use cases. OpenSSH recently provided a roadmap to its eventual deprecation of SHA-1. Join our hosts as they discuss the long, complex process of sunsetting a widely used cryptographic practice, the factors that contribute to these practices continuing beyond their secure lifespans, and the importance of crypto agility.

Root Causes 98: DMARC and Verified Mark Certificates for Email

A new kind of identity certificate is coming that will enable businesses to include their logos in official email they send in order to improve customer confidence and protect against phishing. It is called a Verified Mark Certificate (VMC) and is built upon the DMARC standard, which controls which senders are allowed to send email using any given From address. In this episode our hosts explain VMCs and DMARC and how they will be used and then discuss where they fit in with S/MIME email certific...
