Setup locks down the firewall by default. If you need to open ports for OSSEC agents, syslog devices, or analyst VMs, you can run
so-allow and it will walk you through this process.
so-allow also provides an option to add firewall rules for sensors although you shouldn’t need this under normal circumstances since they should automatically add their own rules.
This program allows you to add a firewall rule to allow connections from a new IP address. What kind of device do you want to allow? [a] - Analyst - ports 22/tcp, 443/tcp, and 7734/tcp [b] - Logstash Beat - port 5044/tcp [c] - apt-cacher-ng client - port 3142/tcp [e] - Elasticsearch REST endpoint - port 9200 [f] - Logstash forwarder - standard - port 6050/tcp [j] - Logstash forwarder - JSON - port 6051/tcp [l] - Syslog device - port 514 [n] - Elasticsearch node-to-node communication - port 9300 [o] - OSSEC agent - port 1514 [s] - Security Onion sensor - 22/tcp, 4505/tcp, 4506/tcp, and 7736/tcp If you need to add any ports other than those listed above, you can do so using the standard 'ufw' utility. For more information, please see: https://securityonion.net/docs/Firewall Please enter your selection (a - analyst, c - apt-cacher-ng client, l - syslog, o - ossec, or s - Security Onion sensor, etc.):
To view existing rules granted through the use of
so-allow, use the following command:
If you choose the
so-allow will also add the
analyst IP address to the Wazuh Whitelist. This will prevent Wazuh Active Response from blocking the
analyst IP address.
