How should I respond to a security vulnerability in my system?

First, assess the severity of the vulnerability. Is it critical, high, medium, or low?

It's a critical vulnerability that could allow remote access.

In that case, immediately isolate the affected system to prevent further exploitation. Then, gather all relevant information.

What information should I gather?

Collect logs, user activity, and any indicators of compromise. This will help in understanding the impact.

Once I have the information, what should I do next?

Next, apply patches or mitigations, notify affected stakeholders, and document the incident for future reference.
