With the SNMP protocol you communicate across the internet. However, this exposes the participating systems to the potential attacks and risks associated with the public internet.
Put the BS2000 systems and management platform which are to be managed in a subnetwork over which you have exclusive control, for instance, behind a firewall. In this way, you can control access to your systems more easily and more centrally and counter any possible attacks.
The security functions implemented in the SNMP agent are based on the fact that its configuration and program files are only accessible to privileged users, usually an administrator. The installation creates these files with the correct privileges.
Check the configuration and program files of the SNMP agent in the BS2000 system at regular intervals to ensure they are only accessible to privileged users.
