For security reasons and to prevent unwanted use and probes of your network it is advised to change all
the default settings in the SNMP configuration window to private, custom values.
6.3.16. Community String
In Versions 1 and 2c of the protocol the community strings identified sets of resources to monitor and
some of these resources could be “read-only” and some could be “read-write”. In most default
installations of SNMP the community string “public” is read-only and returns limited, basic information
about the system being monitored.
Use of Version 1 or 2c protocol is considered to be insecure as clear-text is used and this is easily
compromised.
6.3.17. Security Name
In Version 3 a “Security Name” is similar to a username on other systems. It identifies an authorized user
of the system.
6.3.18. Authentication Password
Authentication is performed by using a user's authentication password to create an authentication key to
sign the message being sent. The signing key is generated from a password that must be at least 8
characters in length.
6.3.19. Privacy Password
A private key is used to encrypt the data portion the message being sent. The private key is generated
from the privacy password that must be at least 8 characters in length.
6.3.20. Remote Logging
For centralized log management and to implement long-term retention of the system logs of the
recorders a Syslog server and port may be specified:
This is a standard feature for Unix/Linux based systems. Contact your server administrator for more
information.
