Huawei HCIP-Security V4.0 認定 H12-725_V4.0 試験問題 (Q40-Q45):

質問 # 40
Sort the intrusion prevention steps in sequence based on the working mechanism of the firewall device.

正解：

解説：

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.

質問 # 41
SYN scanning requires a fully established TCP connection and is recorded in system logs.

A. TRUE
B. FALSE

正解：B

解説：
Comprehensive and Detailed Explanation:
* SYN scanning is a stealthy TCP scanning technique used by attackers to detect open ports.
* How SYN scanning works:
* The attacker sends aSYN packetto a target port.
* If the port isopen, the target responds with aSYN-ACK.
* Instead of completing the handshake with anACK, the attacker sends anRST (reset) packet, leaving the connection half-open.
* Why is this statement false?
* SYN scanning does NOT establish a full connection (three-way handshake).
* It may not always be recorded in system logs, depending on firewall settings.

質問 # 42
Which of the following items are recorded in the IPS service module logs of a Huawei NGFW?(Select All that Apply)

A. Signature name
B. Attack duration
C. Signature ID
D. Source IP address of the attacker

正解：A、B、C、D

解説：
Comprehensive and Detailed Explanation:
* Intrusion Prevention System (IPS) logs record attack details for analysis and response.
* The following information is logged:
* A. Signature ID# Unique identifier for the detected attack.
* B. Source IP address of the attacker# Identifies the origin of the attack.
* C. Attack duration# How long the attack lasted.
* D. Signature name# The specific attack detected (e.g., SQL injection).
* All options are correct because Huawei NGFW logs complete IPS event details.

質問 # 43
Which of the following is not a process for remote users to access intranet resources through SSL VPN?

A. Access accounting
B. User authentication
C. User login
D. Resource access

正解：A

解説：
Comprehensive and Detailed Explanation:
* SSL VPN remote access process includes:
* User login# User enters credentials on the virtual gateway.
* User authentication# Credentials are verified via RADIUS, LDAP, or local authentication.
* Resource access# The authenticated user accesses intranet resources.
* Why is C incorrect?
* SSL VPN does not perform "Access accounting"(which is used in RADIUS-based AAA systems).

質問 # 44
HWTACACS is a centralized information exchange protocol based on the client/server structure. It uses UDP for transmission and performs authentication, authorization, and accounting for users accessing the Internet through Point-to-Point Protocol (PPP) or Virtual Private Dial-up Network (VPDN) and administrative users logging in to devices.

A. TRUE
B. FALSE

正解：B

解説：
Comprehensive and Detailed Explanation:
1##Understanding HWTACACS:
* HWTACACS (Huawei Terminal Access Controller Access-Control System)is aHuawei- proprietaryAAA (Authentication, Authorization, and Accounting) protocol.
* It isbased on the TACACS+ protocolbut optimized for Huawei devices.
Why the Statement is False?
The statement contains atechnical inaccuracyabout thetransport protocolused by HWTACACS.
* Incorrect:"It uses UDP for transmission."
* Correct:HWTACACS uses TCP (Transmission Control Protocol), not UDP.
* TACACS+ and HWTACACS both use TCP (port 49) for reliable communication.
Key Features of HWTACACS:
A screenshot of a computer AI-generated content may be incorrect.

Why TCP is Used Instead of UDP?
* TCP ensures reliable deliveryof AAA messages.
* UnlikeRADIUS (which uses UDP), HWTACACS does not suffer from packet loss issuessince TCP provides retransmission and flow control.
Where is HWTACACS Used?
* Device Login Authentication# Securely managesnetwork administrators accessing Huawei routers, switches, and firewalls.
* Authorization Control# Grants specific command-level privileges to users.
* Accounting# Logs command execution for auditing purposes.
