A. ntop --set-password=testing123
B. ntop --set-new-password=testing123
C. ntop --reset-password=testing123

問題 #118
Which PAM module can be used to restrict login access based on the combination of user, origin, and service?

A. pam_access
B. pam_nologin
C. pam_selinux
D. pam_limits

答案：A

解題說明：
The pam_access module enforces login restrictions defined in the access.conf configuration file, which specifies rules based on combinations of users or groups, the origin (such as a hostname, IP address, or tty), and often the PAM service being used. This allows administrators to build fine- grained login policies, such as allowing a particular user to log in only from specific hosts.
pam_nologin instead simply prevents all non-root logins when the /etc/nologin file is present.

問題 #119
What is the primary purpose of Fail2ban?

A. To monitor log files for repeated failed authentication attempts and dynamically block the offending IP address using firewall rules.
B. To encrypt log files stored on disk.
C. To generate strong random passwords for user accounts.
D. To replace the need for a firewall entirely.

答案：A

解題說明：
Fail2ban is a log-monitoring intrusion prevention tool that scans log files, such as those generated by SSH or web server authentication, for patterns indicating repeated failed login attempts. When a configured threshold of failures from a specific IP address is reached within a defined time window, Fail2ban dynamically inserts a firewall rule (via iptables, nftables, or another supported backend) to temporarily block that IP address, helping to mitigate brute-force attacks without requiring permanent manual firewall configuration.
