NEW QUESTION # 81

A. Xmas Scan

C. FIN Scan
D. IP Scan
E. Zero Scan

Answer: A,C

NEW QUESTION # 82
What is the purpose of OCSP stapling?

A. It allows the certificate authority to revoke a certificate faster.
B. It replaces the need for a Certificate Revocation List entirely.
C. It allows the server, rather than the client, to periodically query the OCSP responder and attach the signed response to the TLS handshake.
D. It encrypts the OCSP request between client and CA.

Answer: C

Explanation:
OCSP stapling allows a web server to periodically query its certificate authority's OCSP responder itself and cache (or "staple") the signed OCSP response directly to the TLS handshake sent to clients. This eliminates the need for each individual client to contact the OCSP responder separately, improving performance and privacy, and also avoids failures if the OCSP responder is temporarily unreachable from the client's network, since the server provides an already-signed, time-stamped response.

NEW QUESTION # 83
In Suricata, what is the purpose of a "rule" file, such as those found in the emerging-threats.rules collection?

A. It configures which network interfaces Suricata should monitor.
B. It defines firewall NAT translation rules.
C. It defines the signatures and conditions used to detect specific types of malicious or suspicious network traffic.
D. It defines user authentication policies for the Suricata management interface.

Answer: C

Explanation:
Suricata rule files contain individual signatures that define specific patterns, protocols, and conditions used to detect malicious or suspicious network traffic, such as known exploit attempts, malware command-and-control communication, or policy violations. Community-maintained rule sets, such as those from Emerging Threats, are commonly used alongside custom, locally written rules to provide broad detection coverage. The network interfaces to be monitored and other operational settings are instead configured in Suricata's main YAML configuration file.

NEW QUESTION # 84
What is the primary function of an Intrusion Detection System (IDS) such as Snort or Suricata operating in network-based mode?

A. To perform DNS resolution for network hosts.
B. To encrypt network traffic between hosts.
C. To actively block malicious traffic before it reaches its destination.
D. To passively monitor network traffic and generate alerts based on signature or anomaly-based detection rules.

Answer: D

Explanation:
A network-based Intrusion Detection System (NIDS), such as Snort or Suricata operating in IDS mode, passively monitors network traffic, typically via a mirrored switch port or network tap, and compares it against a set of signatures or behavioral rules to detect potential malicious activity, generating alerts for further investigation. This differs from an Intrusion Prevention System (IPS), which operates inline with the traffic path and can actively drop or block traffic matching a detection rule in real time, rather than only alerting after the fact.

NEW QUESTION # 85
Which of the following commands lists the extended attributes set on a file?

A. stat
B. lsattr
C. getfacl
D. getfattr

Answer: D

Explanation:
The getfattr command is used to display the extended attributes of a file, such as user-defined metadata or security-related attributes stored outside the standard inode fields. lsattr, in contrast, displays file attributes specific to certain filesystems (such as ext2/3/4), like the immutable or append-only flags. getfacl is used to display POSIX Access Control Lists, not extended attributes.
stat displays general file status information, such as size, permissions, and timestamps, but not extended attributes.
