Cloud Security Podcast by Google
Anton Chuvakin
Cloud Security Podcast by Google focuses on security in the cloud, delivering security from the cloud, and all things at the intersection of security and cloud. Of course, we will also cover what we are doing in Google Cloud to help keep our users' data safe and workloads secure.
We’re going to do our best to avoid security theater, and cut to the heart of real security questions and issues. Expect us to question threat models and ask if something is done for the data subject’s benefit or just for organizational benefit.
We hope you’ll join us if you’re interested in where technology overlaps with process and bumps up against organizational design. We’re hoping to attract listeners who are happy to hear conventional wisdom questioned, and who are curious about what lessons we can and can’t keep as the world moves from on-premises computing to cloud computing.

EP116 SBOMs: A Step Towards a More Secure Software Supply Chain
Guest: Isaac Hepworth, PM focused on Software Supply Chain Security @ Google Cooked questions: Why is everyone talking about SBOMs all of a sudden? Why does this matter to a typical security leader? Some software vendors don’t want SBOM, and this reminds us of the food safety rules debates in the past, how does this analogy work here? One interesting challenge in the world of SBOMs and unintended consequences is that large well resourced organizations may be better equipped to produce SBOMs than small independent and open source projects. Is that a risk? Is the SBOM requirement setting the government up to be overly reliant on megacorps and are we going to unintentionally ban open source from the government? What is the relationship between SBOM and software liability? Is SBOM a step to this? Won’t software liability kill open source? How does Google prepare for EO internally; how do we use SBOM and other related tools? To come back to the food analogy, SBOMs are all well and good, but the goal is not that consumers know they’re eating lead, but rather that our food becomes healthier. Where are we heading in the next five years to improve software supply chain "health and safety"?

EP115 How to Approach Cloud in a Cloudy Way, not As Somebody Else’s Computer?
Guest: Rafal Los, Head of Services Strategy @ Extrahop and Founder of Down the Security Rabbit Hole podcast Topics: You had a very fun blog where you reminded the world that many organizations still approach cloud as a rented data center, do you still see it now? Do you think this will persist for 3, 5, 10 years? Other than microservices, what’re the most important differences between public cloud and a rented data center for a CISO to keep in mind? Analysts say that “cloud is secure, but clients just aren’t using it securely”, what is your reaction to this? Actually, how do you define “use cloud securely”? Have you met any CISOs who are active cloud fans who prefer cloud for security reasons? You also work for an NDR vendor, do you think NDR in the cloud has a future?

EP114 Minimal Viable Secure Product (MVSP) - Is That a Thing?
Guest: Chris John Riley, Senior Security Engineer and a Technical Debt Corrector @ Google Topics: We’ve heard of MVP, what is MVSP or Minimal Viable Secure Product? What problem is MVSP trying to solve for the industry, community, planet, etc? How does MVSP actually help anybody? Who is the MVSP checklist for? Leaders or engineers? How does MVSP differ from compliance standards like ISO 27001, or even SOC 2? How does Google use MVSP? Has it improved our security in some way? How to balance the dynamic nature of security with minimal security basics? The working group has recently completed a control refresh for 2022, what are some highlights?

EP113 Love it or Hate it, Network Security is Coming to the Cloud
Guest: Martin Roesch, CEO at Netography, creator of Snort Topics: What is the role of network security in the public cloud? Networks used to be the perimeter, now we have an API and identity driven perimeter. Are networks still relevant as a layer of defense? We often joke that “you don’t need to get your firewalls with you to the cloud”, is this really true? How do you do network access control if not with firewalls? What about the NIDS? Does NIDS have a place in the cloud? So we agree that some network security things drop off in the cloud, but are there new network security threats and challenges? There’s cloud architecture and then there’s multi cloud and hybrid architectures–how does this story change if we open the aperture to network security for multi cloud and hybrid? Should solutions that provide cloud network security be in the cloud themselves? Is this an obvious question?

EP111 How to Solve the Mystery of Application Security in the Cloud?
Guest: Brandon Evans, Infosec Consultant and Certified Instructor and Course Author at SANS Topics: What got you interested in security and motivated you to make this your area of focus? You came from a developer background, right? Occasionally, we hear the sentiment that “developers don’t care about security,” how would you counter it (and would you?)? How do we encourage developers and operations to use the appropriate security controls and settings in the cloud? Is “encourage” the right word? Can we really do “secure by default” but for developers? What do you think are the main application security issues that developers need to deal with in the cloud? You mentioned software supply chain security, do you treat this as a part of application security? How important is this, realistically, for an average organization and its developers? Going to our favorite subject of threat detection, how do you think we can better encourage developers to supply the logs necessary for our detection and response teams to act upon?

EP110 Detection and Response in a High Velocity and High Complexity Environment
Guest: David Seidman, Head of Detection and Response @ Robinhood Toipics: Tell us about joining Robinhood and prioritizing focus areas for detection in your environment? Tim and Anton argue a lot about what kind of detection is best - fully bespoke and homemade, or scalable off-the-shelf. First, does our framework here make sense, and second, looking at your suite of detection capabilities, how have you chosen to prioritize detection development and detection triage? You're operating in AWS: there are a lot of vendors doing detection in AWS, including AWS themselves. How have you thought about choosing your detection approaches and data sources? Finding people with as much cloud expertise as you can't be easy: how are you structuring your organization to succeed despite cloud detection and response talent being hard to find? What matters more: detection skills or cloud skills? What has been effective in ramping up your D&R team in the cloud? What are your favorite data sources for detection in the cloud?

EP109 How Google Does Vulnerability Management: The Not So Secret Secrets!
Guest: Ana Oprea, Staff Security Engineer, European Lead of Vulnerability Coordination Center @ Google Topics: What is the scope for the vulnerability management program at Google? Does it cover OS, off-the-shelf applications, custom code we wrote … or all of the above? Our vulnerability prioritization includes a process called “impact assessment.” What does our impact assessment for a vulnerability look like? How do we prioritize what to remediate? How do we decide on the speed of remediation needed? How do we know if we’ve done a good job? When we look backwards, what are our critical metrics (SLIs and SLOs) and how high up the security stack is the reporting on our progress? What of the “Google Approach” should other companies not try to emulate? Surely some things work because of Google being Google, so what are the weird or surprising things that only work for us?

EP108 How to Hunt the Cloud: Lessons and Experiences from Years of Threat Hunting
Guest: John Stoner, Principal Security Strategist @ Google Cloud Topics: Please define threat hunting for us quickly, the term has been corrupted a bit What are your favorite beginner hunts to jump start the effort at a new team? How to incorporate hunting lessons in detection? What are the differences for hunting in the cloud? Are there specific data sources you prefer to have access to when threat hunting? In the cloud? Should every organization threat hunt? What are traits you might look for in a threat hunter?

EP 107 How Google Secures It's Google Cloud Usage at Massive Scale
Guest: Karan Dwivedi, Security Engineering Manager, Enterprise Infrastructure Protection @ Google Cloud Topics: Google’s use of Google Cloud is a massive cloud environment with wildly diverse use cases. Could you share, for our listeners, a few examples of the different kinds of things we’re running in GCP? Given that we’re doing these wildly different things in GCP, how do we think about scaling the right security guardrails to the right places in our GCP org? How do you work with application engineering teams and project owner teams to make sure the right controls are there but not getting in the way of business? How do we scale this exemption management process? Are there things we do here that don’t make sense at a smaller scale? Are there emergent challenges that only we would face? How do you correctly federate security responsibilities between the central team defining policy and the constituent user teams actually using the platform? Burnout is a perennial challenge for security teams–what’re you doing to keep your people happy and engaged?
