Bill is a network administrator. He wants to eliminate unencrypted traffic inside his company’s network. He decides to setup a SPAN port and capture all traffic to the datacenter. He immediately discovers unencrypted traffic in port UDP 161.
What protocol is this port using and how can he secure that traffic?
The protocol using UDP port 161 is SNMP (Simple Network Management Protocol). SNMP V1 and V2 use clear text community strings for authentication, which makes them vulnerable to security threats. To secure this traffic, Bill should upgrade to SNMP V3, which includes features like encryption, authentication, and message integrity.
B. Change SNMP to SNMP V3. Explanation: SNMP (Simple Network Management Protocol) is a protocol used for managing and monitoring network devices, such as routers, switches, and servers. SNMP uses UDP port 161 for communication. However, SNMP V1 and V2 use clear text community strings for authentication, making them vulnerable to eavesdropping and other attacks. To secure SNMP traffic, Bill should change the SNMP version to SNMP V3, which provides enhanced security features, such as authentication, encryption, and message integrity. SNMP V3 requires a username and password for authentication, and it supports encryption of the data being transmitted.
