Jul 23, 2020Tap to summarizeAll links and images for this episode can be found on CISO Series (https://cisoseries.com/defense-in-depth-infosec-fatigue/) Have we reached peak InfoSec fatigue? Revolving CISOs and endless cyber recruitment OR the fact that we're spending more money to reduce even greater risk. Is it all leaving our grasp? Check out this post for the basis of our conversation on this week’s episode which features me, David Spark (@dspark), producer of CISO Series, co-host Allan Alford (@allanalfordintx), and guest Helen Patton (@OSUCISOHelen) CISO, The Ohio State University. Thanks to this week's podcast sponsor, Sonrai Security. Identity and data access complexity are exploding in your public cloud. 10,000+ pieces of compute, 1000s of roles, and a dizzying array of interdependencies and inheritances. Sonrai Security delivers an enterprise cloud security platform that identifies and monitors every possible relationship between identities and data that exists inside your public cloud. On this episode of Defense in Depth, you’ll learn: Are we sliding in our effort to get ahead of security issues? There's a sense the tools and our ability isn't keeping up with the onslaught. Are we able to prove risk reduction to show that our efforts are successful? Those people who don't burn out are the ones who thrive on the technical and political challenges of cybersecurity. Disagreement on how you lead a discussion. Should it be story-based or data-based? Classic complaint about cybersecurity is success is measured by the absence of activity. Preventative security is not easily quantifiable as reactive security. CISOs have to step up and show evidence of security's success in the most understandable and digestible format. Suggested measures and metrics: likelihood and impact, business impact analysis, security program maturity curve, framework compliance, pen test results, and threat modeling. FUD (fear, uncertainty, and doubt) may be effective in the short run, but it's exhausting. It never works in the long term. Approach cybersecurity altruistically. If it benefits you and those around you, then it's worth doing. Lean on security vendors to help you show the value of their product. The business impact will be on the CISO's shoulder, but the vendor should help build the case.
Transcribe →Should Risk Lead GRC?
Apr 16, 2020Tap to summarizeAll links and images for this episode can be found on CISO Series (https://cisoseries.com/defense-in-depth-should-risk-lead-grc/) Defining risk for the business. Is that where a governance, risk, and compliance effort should begin? How does risk inform the other two, or does calculating risk take too long that you can't start with it? Check out this post for the discussion that is the basis of our conversation on this week’s episode co-hosted by me, David Spark (@dspark), the producer of CISO Series, and Allan Alford (@AllanAlfordinTX). Our guest is Marnie Wilking (@mhwilking), global head of security & technology risk management, Wayfair. Thanks to this week’s podcast sponsor, Qualys. Qualys is a pioneer and leading provider of cloud-based security and compliance solutions. On this episode of Defense in Depth, you’ll learn: The model of risk = likelihood x impact doesn't take into account the value of assets. Assets have to be valued first before you calculate risk. Is the reason risk isn't used to lead governance, risk, and compliance (GRC) because it's so darn hard to calculate? Many CISOs say their toughest job starting out is trying to understand what the crown jewels are and what the board's risk tolerance is. Risk management allows the board to know when you have enough security. Some assets may require eight layers where others may only require one or two. Determining likelihood of an attack involves a good amount of guesswork. We've discussed on a previous episode of CISO/Security Vendor Relationship Podcastthat we don't go back to see how good our risk predictions were. If you want to get better at it, you should. Otherwise, it will always be guesswork. Even if you can get someone to agree what their risk tolerance is, or what asset is of importance, trying to get agreement among a group can be a blocker. Keep in mind that each person is going to have a different viewpoint and concerns. Knowing risk appetite is critical. You can apply security controls without knowing it, but that's providing a unified security layer across all data, people, and applications when they are all not equal when it comes to asset valuation.
