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 37: Quantum Apocalypse - Will Quantum Annealing Break Cryptography?

Quantum annealing is a special case of quantum computing for which the engineering challenges are lessened - and therefore we expect computers of this sort to achieve stability sooner. In this episode we examine the potential for the quantum annealing approach to break RSA-based cryptography sooner than most people have been expecting, and the difficulty of predicting the "Z date" at all.

Root Causes 34: Shadow IT and PKI

Shadow IT has become a fact of the modern enterprise. SaaS, BYOD, outsourced development, embedded IT, DevOps, and public cloud have all chipped away at the CIO's ability to oversee and control the enterprise's technology systems. This fragmentation leads to identity and access challenges that can affect security, governance, auditability, and compliance. Join our hosts as they discuss these challenges and what IT departments can do to address them.

Root Causes 33: Prepare for One-year Limits on SSL Certificates

The CA/Browser Forum faces a proposed ballot to limit the maximum duration of an SSL certificate to 13 months. Even if this ballot fails, browsers such as Google Chrome have the ability to simply distrust certificates of longer duration, creating the same de facto situation. Our hosts discuss the trend to shorter certificates, the pluses and minuses of decreased maximum term, and automation as the only solution to fill the gap.

Root Causes 32: Why Do Browsers and Academic Research Say Different Things About EV SSL?

Breaking research from two esteemed universities shows that sites with Extended Validation SSL certificates are much less likely to be engaged in criminal behavior like malware and phishing. And yet, leading browsers are reducing or removing EV information from the interface. Join our hosts as they explore the research results, this paradoxical browser behavior, and the effect it's likely to have on consumer security.
