35. Steve, a scientist who works in a governmental security agency,
developed a technological solution to identify people based on walking
patterns and implemented this approach to a physical control access.
camera captures people walking and identifies the individuals using Steve's
approach. After that, people must approximate their RFID badges. Both the
identifications are required to open the door. In this case, we can say:
A
a. The solution implements the two authentication factors: physical
object and physical characteristic
9

b. The solution will have a high level of false positives
c. Biological motion cannot be used to identify people
d. Although the approach has two phases, it actually implements just one
authentication factor
36. A network administrator discovers several unknown files in the root
directory of his Linux FTP server. One of the files is a tarball, two are shell
script files, and the third is a binary file is named "nc." The FTP server's
access logs show that the anonymous user account logged in to the server,
uploaded the files, and extracted the contents of the tarball and ran the
script using a function provided by the FTP server's software. The ps
command shows that the nc file is running as process, and the netstat
command shows the nc process is listening on a network port. What kind of
vulnerability must be present to make this remote attack possible?
