Question

Identify the udp port that network time protocol (ntp) uses as its primary means of communication?

Answer 1

Answer:

UDP Port 123

Explanation:

NTP uses port 123 for communication between systems in network. This port defines time synchronization between computers in network. This type of protocol helps in data base management, authenticate schemes, audit / log information, etc. The attacker gets a large reply by spoofing source IPs by sending a query to the vulnerable NTP server. On solution to get ourselves away from attack is that, we can separate the NTP and DNS infrastructure from HTTPS.
