Using Novell Security Manager
4.1.5.
SNMP
The Simple Network Management
Protocol (SNMP) monitors and manages the local network. SNMP allows
the administrator to make quick queries about the condition of the network devices, such as the number and configuration of the network
interfaces, the forwarded traffic, the current processes and hard disk utilization. Next to the current state, tendencies and time rows are interesting.
They give a detailed insight into the functions of a network – the history
can be monitored and remedied before turning into a real problem.
Configure the access rights to the SNMP service in the SNMP Access
window. The users of the configured networks can then conduct queries
about the SNMP server on Novell Security Manager with their read only
rights.
Security Note:
The SNMP data traffic (Protocol version 2) between Novell Security
Manager and the network is not encrypted.
Authorizing Access to the SNMP Server:
1.
Enable SNMP Access by clicking the Enable button.
2.
From the Allowed Networks selection field, select the networks that
you wish to allow for accessing the SNMP server.
3.
Enter the Community String in this entry field.
4.
Save your configuration by clicking Save.
In the SNMP Traps window
you can define a Trap-Server,
to which relevant information
for the system administration
is sent as SNMP Traps. To recognize those Traps a special SNMP monitoring
software is required.
The messages, which are sent as SNMP Trap, contain the Object ID
(OID). The OID for messaging events (1500), the classification of the
message (DEBUG = 0, INFO = 1, WARN = 2, CRIT = 3) and the relevant
error code (000 bis 999) are attached.
Example: The notification INFO-354: Intrusion Protection Pattern
Up2Date succeeded Intrusion Protection Pattern Up2Date succeeded has in
this case the OID 1.3.6.1.4.1. and is assigned the following string:
