Additional information.
The first version of the protocol
SNMPv1
is organized most simply and least safely. The basis of
SNMPv1
security is the Com-
munity-based Security Model, i.e. authentication based on a single text string-a kind of group name and a two-in-one pass-
word (there is even the term
"community- string"
). In fact, the name
community
and this is a kind of password. This "key" is
broadcast in the body of the message in clear text.
Community
are of two types:
read-only
(read only values of variables)
and
read-write
(reading and writing values of variables). Despite the low level of security,
SNMPv1
due to the ease of imple-
mentation is still in use.
SNMP version 2 in the latest release
SNMPv2c
also uses
Community-based Security,
however, owing to the changes intro-
duced in it, the performance of the protocol is significantly improved, and security improvements are also made.
The third version of the protocol
SNMPv3
already supports
User-based Security Model
and
traffic encryption
.
By default, the Resilient Power Control Module contains
community
—
"public"
with read-write
access.
Note. The SNMP community name is case sensitive.
