Match the description about virtual systems and VPN instances.
Correct Answer:
Explanation:
1. Virtual System # Services and routes can be isolated.
* A virtual system (VS)in Huawei firewalls is afully isolated security instancewithin a single physical firewall.
* Each virtual system hasseparate services, routing tables, policies, and security rules, ensuring full isolation between different users or tenants.
2. VPN Instance # Only route isolation can be implemented.
* AVPN instance (VRF - Virtual Routing and Forwarding)providesroute isolationfor different customer networks butdoes not isolate services or security policies.
* This is typically used inMPLS VPN deploymentswhere different customers share the same physical device but need isolated routing tables.
3. VPN Instance # VPN instances are automatically generated.
* In someMPLS VPNorSDN-managed networks, VPN instances can beautomatically createdwhen customer configurations are pushed via controllers.
* Dynamic routing protocols (e.g., BGP/MPLS VPN) can automatically generateVRF instancesbased on network policies.
4. Virtual System # An instance needs to be manually created.
* Unlike VPN instances,virtual systems must be manually createdby an administrator on the firewall.
* Each virtual system functions as acompletely independent firewall, requiring manual configuration of interfaces, policies, and routing settings.

Sort the intrusion prevention steps in sequence based on the working mechanism of the firewall device.
Correct Answer:
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.
