Cyberside Chats: Cybersecurity Insights from the Experts

In this live episode of Cyberside Chats, we dig into security debt and why it continues to sit behind so many major incidents. This is the risk that builds quietly over time when controls are available but never turned on, systems aren’t fully decommissioned, or ownership is unclear.

Using recent examples like Stryker, along with Change Healthcare and Colonial Pipeline, we walk through how attackers don’t always need sophisticated techniques. In many cases, they just take advantage of gaps that have been sitting there for years. We also introduce a simple framework to think about security debt across identity, lifecycle, architecture, governance, and operations, and why most real-world incidents cut across more than one of these areas.

We close with a look at how things are changing. With AI accelerating exploit development, the window to fix these issues is getting smaller. What used to be a manageable delay is quickly becoming real exposure.

Audience takeaways

1. Require dual approval for destructive admin actions. Any system where one administrator can wipe, delete, or lock out at scale — Intune, Entra, identity providers, backup consoles, remote management tools — should require a second administrator to approve the action before it executes. Microsoft's Multi Admin Approval does this for Intune. Most identity and backup platforms have an equivalent. Turn it on. Stryker is the case study for what happens when you don't. (Addresses: Governance debt primarily; reduces Identity and Architecture debt blast radius.)
2. Enforce phishing-resistant MFA on every administrator and every remote-access path. Not "available," not "recommended" — enforced, with no exceptions. Every admin account. Every VPN. Every Citrix or similar remote portal. Change Healthcare is the case study for what a single missing MFA checkbox costs. (Addresses: Identity debt.)
3. Separate admin work from daily work. Admins should use dedicated, hardened devices for privileged tasks — never the same laptop they use for email and browsing. An infostealer on an admin's everyday device is how privileged credentials walk out the door; isolating admin sessions removes that path. Microsoft calls this pattern Privileged Access Workstations; other vendors have equivalents. This directly addresses how attackers likely got Stryker's admin credentials in the first place. (Addresses: Architecture debt; reduces Identity debt.)
4. Cut your patch SLA in half and plan capacity accordingly. Whatever your current median time-to-remediate is for critical vulnerabilities, assume you need to hit half of it within the next year. The Mythos research shows attacker timelines are compressing from weeks to hours. Your patch program needs budget, automation, and process changes to keep up — not pep talks. (Addresses: Operational debt.)
5. Put expiration dates on every security exception and review them quarterly. If your exception register contains entries with no expiration date, no owner, or a "revisit in the future" stub — those are governance debt. Every open exception should have an expiration date, a named owner, and a scheduled review. Exceptions are fine; forever-exceptions are not. This is also how you close the loop on lifecycle debt: an EOS system running past its decommission date is just an exception someone never wrote down. (Addresses: Governance debt and Lifecycle debt.)
