Option A: Detection mode allows Falcon to monitor and alert on threats, but it does not create a direct privilege escalation risk. While switching to prevention mode enhances security, the misconfiguration in this scenario is related to IAM permissions rather than Falcon sensor settings.
Option B: Restricting SSH access to specific IPs is a best practice for minimizing exposure. While open SSH access is a security risk, a properly restricted IP range does not directly contribute to privilege escalation.
Option C: Granting Administrator Access to an EC2 instance profile is a critical security misconfiguration. It allows any process running on the instance to assume unrestricted administrative privileges, potentially leading to privilege escalation and lateral movement by an attacker. This is a high-risk practice that should be avoided by implementing least privilege principles.
Option D: Enforcing MFA enhances security by requiring an additional authentication factor.
While MFA alone does not prevent all privilege escalation risks, it does not contribute to misconfiguration or high-risk practices.
