My instinct was to say the DMZ server because it's internet-facing and more exposed.
Start by clarifying that the decision depends on risk assessment, not a fixed rule. Evaluate the exposure and potential impact of each vulnerability, considering factors like exploitability, data sensitivity, and business criticality. Then prioritize patching the server that poses the greatest immediate risk to the organization.
Pro tip: Mention that you would also consider the possibility of lateral movement from the DMZ to the internal network, and the importance of having a rollback plan in case the patch causes issues.
Determine which server is more exposed to potential attackers. The DMZ server is typically internet-facing, so it may be at higher risk of exploitation.
Consider the potential impact if the vulnerability is exploited. Internal servers might contain more sensitive data or provide access to critical systems.
Check if there are known exploits in the wild and how easily the vulnerability can be exploited. A wormable vulnerability might spread quickly, increasing urgency.
Combine exposure, impact, and exploitability to determine which server presents the highest risk. Patch that one first.
If immediate patching isn't possible, apply temporary mitigations (e.g., firewall rules, WAF) and monitor for signs of compromise.
