UDP_wala_Scanning

Which technique in UDP scanning is used to bypass detection mechanisms like firewalls, IDS, or IPS

• ICMP-based Firewall Technique

• Advanced Encryption Technique

• Advanced Evasion Technique

• Data Encryption Technique

Minimizing detection by IDS/IPS systems. By fragmenting packets or altering payloads, we can bypass some firewalls.

Which of the following is not a field present in the UDP header

• Checksum

• Data field

• Source port

• Length

Myth: UDP scanning is used to detect open UDP ports on a target system by sending UDP packets and analyzing the response. Accept or Reject?

Which DDoS attack exploits UDP's connectionless nature to overwhelm network resources?

• Reflection-based UDP attack

• SYN flood attack

• UDP fragmentation attack

• UDP flood attack

User Datagram Protocol (UDP) is a lightweight protocol that operates at which layer of the OSI model?

• Layer 4

• Layer 2

• Layer 3

• Layer 5

Acknowledgment segment is present in UDP. True or False

• False

• True

If no response is received, it may indicate that the port is open (depending on firewall configurations), whereas receiving an ICMP "port unreachable" message confirms ____________.

• port is open

• port is filtered

• port is closed

• port is unreachable

Which technology uses UDP for real-time voice communication in services like Skype and WhatsApp?

Bonus: What is the purpose of using a pseudo-header in verifying UDP packets?

• To confirm the integrity of data within the UDP packet during transmission.

• To ensure that the UDP packet has reached its correct destination.

• To ensure the source address is validated in the communication process.

• To check the routing path taken by the UDP packet.
