問題文
A retailer's engineer must explain why an incident that started in a store's guest wireless network reached the store's inventory server. Both are on separate segments and the boundary between them has rules. What should the investigation examine?
選択肢
- Whether the guest wireless network's encryption was broken, allowing the attacker to recover credentials that were valid on the inventory segment and to use them to authenticate to the inventory server directly from the guest network.
- Whether the inventory server had current patches.
- Which rule permitted the path and whether a shared service on the inventory segment was reachable from the guest segment.
- Whether the guest network's address range overlaps the inventory segment's, since an overlap can send guest traffic straight to the server.
