, Active scanning - Correct Answers: An active scan transmits to the nodes within a network to determine
exposed ports and can independently repair security flaws. It can also simulate an attack to test for
vulnerabilities and can repair weak points in the system.
Passive scanning - Correct Answers: A passive scan tries to find vulnerabilities without directly
interacting with the target network. The scan identifies vulnerabilities via information exposed by
systems in their normal communications. You can set a scanner to scan constantly or at specific times.
Point in time - Correct Answers: A scan can only obtain data for the time period when it runs. For
example, some weaknesses may be exposed only when systems are operating at peak capacity, at
certain times of day, or even at certain times of the year.
New vulnerabilities - Correct Answers: Scans can only identify known vulnerabilities. This give an
attacker that uses a new attack an advantage, as scans are written only for vulnerabilities that have been
previously exploited.
Active assessment - Correct Answers: In an active assessment, specifically created packets are sent to
target nodes to determine the OS of the domain, the hosts, the services, and the vulnerabilities in the
network. nmap is a useful tool for this assessment.
Passive assessment - Correct Answers: Using sniffer traces from a remote system, you can determine the
operating system of the remote host as well as a list of the current network work. Wireshark is a
common tool for this type of information gathering and analysis.
External assessment - Correct Answers: This type of assessment looks for ways to access the network
infrastructure through open firewall ports, routers, web servers, web pages, and public DNS servers.
Internal assessment - Correct Answers: The ethical hacker can also be inside the network, testing the
internal networks and systems.
Host-based assessment - Correct Answers: This assessment focuses on all types of user risks, including
malicious users and untrained users as well as vendors and administrators. Host-based assessment can
also test the vulnerability of databases, firewalls, files, and web servers, as well as flag configuration
errors.
