NEW QUESTION # 35
Sort the intrusion prevention steps in sequence based on the working mechanism of the firewall device.
Answer:
Explanation:
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.
NEW QUESTION # 36

* An HTTP flood attackis a type of DDoS attack where an attacker sendsa large number of HTTP requeststo a target server, overloading its resources.
* Attackers often use botnets or spoofed IP addressesto send forged HTTP requests, making it difficult to differentiate between legitimate and malicious traffic.
2##What is Happening in the Figure?
* TheAnti-DDoS devicedetects an abnormally high number of HTTP requests from certain IPs.
* Itchallenges suspicious clientsby requiring them to complete an authentication step (such as entering a verification code).
* Legitimate users can pass the authentication and get whitelisted, while bots and attackers fail to respond and are blocked.
3##Why is "Enhanced Mode" the Correct Answer?
* Enhanced Modeis an advancedsource IP detection technologythat uses verificationcodes or JavaScript challenges to distinguish real users from bots.
* Key features of Enhanced Mode:
* Verification challenge(e.g., CAPTCHA, JavaScript check).
* Whitelisting of verified usersto prevent further verification delays.
* Blocks attack sources that fail to respond to verification.
* In the figure, the systemprompts suspicious users to enter a verification codebefore allowing further access.
* Attackers typicallydo not respond, while legitimate userscomplete the challenge and continue browsing normally.

SYN scanning requires a fully established TCP connection and is recorded in system logs.
- A. TRUE
- B. FALSE
Answer: B
Explanation:
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.
