QUESTION NO: 3
Sort the intrusion prevention steps in sequence based on the working mechanism of the firewall device.
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.
QUESTION NO: 4
Before configuring DDoS attack defense, you must configure different thresholds for defense against different types of attacks. Each threshold can be considered an upper limit for normal network traffic.
When the rate of traffic exceeds the pre-configured threshold, the firewall considers it to be attack traffic and takes a corresponding action to defend against it.

Explanation:
A screenshot of a computer error message AI-generated content may be incorrect.
POST # Sending Information to the Server
* ThePOST methodin HTTP is used to send data to a web server.
* Examples include:
* Submitting login credentials.
* Posting comments or messages on a forum.
* Uploading files via web applications.
* UnlikeGET, POSThides sensitive information in the request body, making it more secure for transmitting login credentials or personal data.
Internet Access Using a Proxy # Firewall Deployment for Proxy Access
* Aproxy serverallows users toaccess the internet through a controlled gateway.
* To enforce security policies, afirewall must be deployed between the intranet and the proxy server.
* Proxies are used for:
* Content filtering(blocking unwanted websites).
* Access control(restricting web usage based on user roles).
* Anonymization(hiding the user's original IP address).
File Upload/Download Size # Controlling Upload Limits
* Firewalls and security devicescan restrict file upload/download sizesto:
* Prevent excessive bandwidth usage.
* Block potentially malicious file uploads.
* Alert and Block Thresholds:
* Alert threshold:Logs a warning if a file exceeds a specific size.
* Block threshold:Prevents files larger than the configured limit from being uploaded or downloaded.
QUESTION NO: 6
*In the data filtering profile on the firewall, keyword group "Keyword" is invoked in the upload direction of HTTP applications, the action is block, and the keyword group is invoked in the security policy. Given this, if the regular expression "b.d" is configured in the keyword group "Keyword," which of the following texts can be posted by internal employees on the forum?
