Option A: Immediately deleting assets without investigation can cause disruptions if they are in use by critical services. Verification is essential before taking action.
Option B: Unmanaged public-facing assets pose a significant security risk. The best practice is to identify ownership, assess their legitimacy, and either enforce security policies or decommission them if unnecessary. Shadow IT, forgotten deployments, or misconfigured assets can all lead to breaches.
Option C: Network segmentation can limit exposure, but it does not address the root cause--why these assets exist and whether they are necessary or unauthorized.
Option D: Restricting outbound traffic may reduce risk, but it does not address the issue of unmanaged public exposure. Attackers could still exploit misconfigurations or known vulnerabilities on these assets.
