DNS Spoofing / posioning Quiz

What is DNS spoofing?

• An attack where an attacker introduces false DNS responses to a DNS resolver, causing it to return incorrect IP addresses

• An attack where an attacker corrupts the DNS cache on a server, causing it to return incorrect IP addresses

• A method to speed up DNS queries

• A process of cleaning up old DNS records

How does DNS spoofing work?

• By corrupting the DNS cache of a DNS resolver

• By intercepting or predicting a DNS query and sending a spoofed response before the legitimate response arrives

• By encrypting DNS responses

• By increasing the TTL of DNS entries

What is the primary scope of DNS spoofing?

• Server-side attack affecting multiple users

• Client-side attack typically targeting individual users or devices

• Network-wide attack affecting all devices

• Internet-wide attack

What is DNS server cache poisoning?

• An attack where an attacker introduces false DNS responses to a DNS resolver

• An attack where an attacker corrupts the DNS cache of a DNS resolver, causing it to return incorrect IP addresses for specific domain names

• A method to speed up DNS queries

• A process of cleaning up old DNS records

How does DNS server cache poisoning work?

• By intercepting DNS queries and sending spoofed responses directly to the client

• By intercepting or predicting a DNS query from the resolver to the authoritative DNS server and sending a forged response before the legitimate response arrives

What is the primary scope of DNS server cache poisoning?

• Client-side attack typically targeting individual users or devices

• Server-side attack affecting multiple users relying on the compromised DNS server

• Network-wide attack affecting all devices

• Internet-wide attack

Which of the following is a key difference between DNS spoofing and DNS cache poisoning?

• DNS spoofing affects multiple users, while DNS cache poisoning affects individual users

• DNS spoofing involves corrupting the DNS cache, while DNS cache poisoning involves intercepting DNS queries

• DNS spoofing affects individual users and is temporary, while DNS cache poisoning affects multiple users and can be long-lasting

• DNS spoofing encrypts DNS responses, while DNS cache poisoning decrypts them

Which of the following is a mitigation technique for DNS spoofing?

• Using DNSSEC

• Reducing TTL values

• Securing communication channels and implementing query ID randomization

• Regular monitoring and updates of DNS resolver software

Which of the following is a mitigation technique for DNS cache poisoning?

• Using query ID randomization

• Using DNS over HTTPS

• Implementing DNSSEC to ensure data integrity

• Encrypting DNS responses

A cyber attack sometimes called DNS poisoning that redirects the user to a fake website

• Pharming
• Removable media
• Malware
• Hacker
• Blagging
