◆ Comments from the Speaker

"After attending this, you can grow into an expert in Microsoft's vulnerability response! Not only those announced by MS as "Critical" are necessarily critical. I will also explain how to determine which vulnerabilities require your organization's response, referencing factors like the existence of PoC and CVSS vector values."

◆ Past Events

At the previous session (held on 6/13), a total of 44 people participated, with 5 attending in person and 39 online.

"Should you really respond to that vulnerability? Focusing only on 'Critical' can lead to dangerous oversights."
