NEW QUESTION # 42
What is the purpose of the "ausearch" command in relation to the Linux audit framework?

A. To add new audit rules to the running kernel.
B. To generate summary reports of audit statistics.
C. To search and filter existing audit log entries based on criteria such as key, user, or time range.
D. To restart the auditd service.

Answer: C

Explanation:
The ausearch command is used to search through the audit log for specific events matching given criteria, such as a rule key (-k), a specific user (-ua), a time range (-ts/-te), or a system call.
This is particularly useful for investigating specific security events flagged by keyed audit rules.
aureport, in contrast, generates summarized, aggregate reports from audit data (such as counts of logins or file accesses), while auditctl is used to manage the rules themselves rather than search existing logs.

NEW QUESTION # 43

C. setfacl
D. getfattr

NEW QUESTION # 44
Which command-line tool is commonly used to test and verify TLS/SSL configuration and certificate details of a remote server?

A. openssl s_client
B. ss -tlnp
C. tcpdump
D. nmap -sV

Answer: A

Explanation:
The "openssl s_client" command connects to a remote server using TLS/SSL and displays detailed information about the negotiated protocol version, cipher suite, and the server's certificate chain, making it a common tool for troubleshooting and verifying HTTPS or other TLS- secured services. nmap's version detection can identify running services but does not provide the same depth of TLS handshake detail, tcpdump captures raw packets, and ss displays socket statistics rather than TLS-layer details.
