Query: Don't Forget to Lock the Front Door! Inferring the Deployment of Source
  Address Validation of Inbound Traffic   This paper concerns the problem of the absence of ingress filtering at the
network edge, one of the main causes of important network security issues.
Numerous network operators do not deploy the best current practice - Source
Address Validation (SAV) that aims at mitigating these issues. We perform the
first Internet-wide active measurement study to enumerate networks not
filtering incoming packets by their source address. The measurement method
consists of identifying closed and open DNS resolvers handling requests coming
from the outside of the network with the source address from the range assigned
inside the network under the test. The proposed method provides the most
complete picture of the inbound SAV deployment state at network providers. We
reveal that 32 673 Autonomous Systems (ASes) and 197 641 Border Gateway
Protocol (BGP) prefixes are vulnerable to spoofing of inbound traffic. Finally,
using the data from the Spoofer project and performing an open resolver scan,
we compare the filtering policies in both directions.
