問題 #48
Which of the following statements are true about SYN scanning attacks?(Select All that Apply)

A. When the scanner sends a SYN packet, if the peer end responds with a SYN-ACK packet, the scanner then responds with an ACK packet to complete the three-way handshake.
B. When the scanner sends a SYN packet, an RST response indicates a closed port.
C. When the scanner sends a SYN packet, a SYN-ACK response indicates an open port.
D. If the peer end does not respond to the SYN packet sent by the scanner, the peer host does not exist, or filtering is performed on the network or host.

答案：B,C,D

解題說明：
Comprehensive and Detailed Explanation:
* SYN scanning is a stealthy technique used to identify open ports on a target system without fully establishing a TCP connection.
* How SYN scanning works:
* The scanner sends aSYN packetto the target port.
* The target responds based on the port state:
* SYN-ACK # Port is open(Correct - D).
* RST # Port is closed(Correct - A).
* No response # The host does not exist, or a firewall is blocking it(Correct - B).
* The scanner doesnot send an ACK(unlike a full TCP connection). Instead, it sends anRSTto avoid detection.
* Why is C incorrect?
* In SYN scanning, the scanner does NOT send an ACK to complete thehandshake. Instead, it sends an RST to abort the connection.

問題 #49
Which of the following actions can be performed when the firewall identifies file anomalies?(Select All that Apply)

A. Alarm
B. Block
C. Delete attachment
D. Allow

答案：A,B,C

解題說明：
Comprehensive and Detailed Explanation:
* Firewalls with advanced security features(such asIPS, Antivirus, and File Filtering) candetect and respond to file anomalies.
* Actions that can be taken when an anomaly is detected:
* A. Alarm# Generates a log entry and notifies the administrator.
* C. Block# Prevents the file from being transferred.
* D. Delete attachment# Removes malicious attachments from emails.
* Why is B incorrect?
* Allowing a detected malicious file is not a valid security response.

* Huawei HCIP-Security Guide # File Filtering & IPS Protection

問題 #50
Sort the intrusion prevention steps in sequence based on the working mechanism of the firewall device.

答案：

解題說明：

Explanation:
Intrusion Prevention Systems (IPS) in firewalls follow amulti-step processto detect and mitigate threats. The steps occur in a logical sequence:
1##Step 1: Identifies and Parses Application-Layer Protocols
* The firewall firstidentifies the protocol being used(e.g., HTTP, FTP, DNS, SMTP).
* Parsing the protocol helps the IPS engineunderstand how the data is structuredand what types of attacks might be embedded.
* This step is crucial for detectingprotocol-based attackslike SQL injection or cross-site scripting (XSS).
2##Step 2: Reassembles IP Fragments and TCP Flows
* Attackers oftensplit malicious payloads across multiple packetsto evade detection.
* The firewallreassembles fragmented packets and TCP flowsto reconstruct the full data stream.
* This step is critical for detectingevasion techniques such as fragmented attacks or out-of-order packet attacks.
3##Step 3: Performs Signature Matching
* Once the full data stream is reassembled, the IPScompares it against known attack signatures.
* Signature matching helps detect:
* Malware patterns(e.g., botnets, Trojans).
* Exploits targeting vulnerabilitiesin software and operating systems.
* Firewalls usepredefined signature databasesthat are regularly updated.
4##Step 4: Performs the Response Action Based on the IPS Profile
* If an attack is detected, the firewall takes anaction based on the IPS policy:
* Block the traffic(drop malicious packets).
* Alert the administrator(generate logs and alerts).
* Rate-limit traffic(slow down potential attack sources).
* Theresponse mechanism is customizablebased on security requirements.

問題 #51
Which of the following statements is false about the ATIC system architecture?

A. One management center can centrally manage multiple geographically dispersed detecting and cleaning devices.
B. SecoManager functions as the management center and uses the Browser/Server architecture.
C. The ATIC management server manages detecting and cleaning devices.
D. The ATIC consists of the management server, collector, and controller.

答案：D

解題說明：
Comprehensive and Detailed Explanation:
* ATIC (Advanced Threat Intelligence Center) systemconsists of:
* SecoManager (Management Center)# Manages security policies.
* Detection devices# Analyze traffic for threats.
* Cleaning devices# Mitigate attacks.
* Why is B false?
* ATIC architecture does not include a "collector and controller" structure.
