What is the recommended action for the default SNMP community name?

Changing the default SNMP community name is considered a best practice for security reasons. The default name "public" is widely known and often targeted by attackers, making systems more vulnerable to unauthorized access and data exposure. By changing the community name to something unique and complex, you can help mitigate the risk of exploitation by attackers who might attempt to gain access to network devices via SNMP.

Using a strong, custom community name makes it harder for malicious actors to guess or exploit known credentials, thus enhancing the overall security posture of the network. This practice aligns with broader security principles that advocate for minimizing the use of default settings as they can be readily exploited by individuals with malicious intent.
