PCIP -CHAPTER 3 PCI DSS REQUIREMENT EXAMQUESTIONS AND ANSWERS
What is Requirement 1? - Answer Install and maintain a firewall and router
setup to secure cardholder data.
What exactly does a firewall do? - ANSWER (1) This regulates traffic between
an entity's internal networks and untrusted networks, as well as traffic into and
out of sensitive locations like the cardholder data environment.
(2) They examine and manage all network traffic, prohibiting communications
that do not follow the rules stated in the configuration settings.
(3) All systems in the cardholder data environment must be safeguarded against
illegal access from any untrusted networks, and firewalls play an important part
in this protection.
Req. 1.1.1 A structured process for approving and verifying all network
connections, as well as changes to firewall and router configurations. -
ANSWER Why? Without approval and testing of changes, records of changes
may not be updated, resulting in mismatches between network documentation
and real configuration.
1.1.2 Maintain a current network diagram that shows all links between the
cardholder data environment and other networks, including wireless networks. -
ANSWER Why? Without current network diagrams, devices may be ignored
and mistakenly left out of the security controls created for PCI DSS, making
them vulnerable to compromise.
1.1.3 Maintain a current diagram of all cardholder data flows across systems
and networks. - ANSWER: Why? Network and cardholder data flow diagrams
assist an organization in understanding and tracking the extent of their
environment by illustrating how cardholder data moves across networks and
between particular systems and devices.
