Dear Shaik Mahboob Ali,
From your question:
I have a IT security high risk for assigning a default community string on DCE server. How we can mitigate the risk ?
You are right, it can be a security vulnerability. Therefore, as a rule, it is strongly recommended by all device manufacturers to change the default name:
- for ro community string from the default string public to its unique string (for example, a conventional hard-to-read combination of letters in different registers and digits);
- for rw community string from the default string private to its unique string (for example, a conventional hard-to-read combination of letters in different registers and digits);
And of course this secret strings should be kept secret.
I would like to have a support regards to community string on server as " Public". What is the impact if i change this string to a new name on Data Center Expert server.
Of course, the above SNMP community strings must first be changed on all of your SNMP enabled devices. And then make similar changes in the DCE software accordingly. For example, how to do this in DCE software is clearly visible from my screenshot:
I.e., go to the Device -> SNMP Device Comminication Settings... -> Device Scan Settings... Then mark all needed your SNMP devices by Selecte/Deselect All checkbox. After that press on the button Edit Device Scan Settings... and make corresponding changes about Read Comminity and Write Community strings.
If you did everything correctly, then you will be protected from a security vulnerability and do not lose monitoring of all your SNMP enabled devices in DCE software.
With respect.
