Hi,

I am currently looking at setting up something like this:

Security devices > syslog server > Microsoft Sentinel

In order to tie down/restrict somewhat the access this syslog server has, is there a list of known IPs for Microsoft Sentinel?

Another bonus question please :D

For one of the firewalls (one of the security devices mentioned above) we are looking to send a full set to Sentinel via this syslog server, PLUS a smaller subset of the SAME log (but with only selected columns/fields) to another Log Analytics workspace. This might be outside of scope of the syslog server agent but is there a guide on how to get this setup please?

Many thanks.

JT

    There are no special IPs for Syslog. It encrypts the traffic using TSL 1.2 to the standard public endpoints. Both the AMA and MMA agents share the same firewall requirements. https://learn.microsoft.com/en-us/azure/azure-monitor/agents/log-analytics-agent#firewall-requirements

    The MMA agent on Linux does not support dual homing. The new AMA agent does support dual homing on Linux. I assume you would simply setup two DCR rules.
