Security implications<br>

- SNMP versions 1 and 2c are subject to packet<br>
sniffing<<a href="http://en.wikipedia.org/wiki/Packet_sniffer" target="_blank">http://en.wikipedia.org/wiki/Packet_sniffer</a>>of the clear text<br>
community string from the network traffic, because they do<br>
not implement encryption.<br>
- All versions of SNMP are subject to brute<br>
force<<a href="http://en.wikipedia.org/wiki/Brute_force_attack" target="_blank">http://en.wikipedia.org/wiki/Brute_force_attack</a>>and dictionary<br>
attacks <<a href="http://en.wikipedia.org/wiki/Dictionary_attack" target="_blank">http://en.wikipedia.org/wiki/Dictionary_attack</a>> for guessing the<br>
