What are the problems of using community strings in SNMP?
What will be an ideal response?
The use of community strings in the first two versions of SNMP, SNMPv1 and SNMPv2, created several vulnerabilities. First, the default SNMP community strings for read-only and read-write were public and private, respectively. Administrators who did not change these default strings left open the possibility of an attacker taking control of a network device. Second,many administrators who reset the community strings used weak strings (passwords) for security. Finally,community strings are transmitted in cleartext, meaning that an attacker with a packet sniffer can view the contents of the strings as they are transmitted.
