Assign the reservations to the correct VLAN (where applicable). ![]() Assign a static DHCP reservation to the hosts's MAC address.Log into your home router (or DHCP server).Things will break if hosts lose their DHCP lease.Īfter you create the containers do the following: Please give your containers DHCP reservations! Set your DNS domain and servers as desired.Memory: 4 GiB (1 GiB swap) – 8 GiB recommended.Log into Proxmox and create five Linux Containers for your infrastructure. I would strongly advise on giving each of your containers a DHCP reservation in your home router, so that your NIDS/SIEM are not disrupted by possible IP address changes. As long as the endpoint can establish a TCP/IP connection with the Wazuh Manager, it can ship the logsĭHCP IP Reservations Strongly Recommended.Wazuh agent installed on any server or workstation to be monitored.Successfully connecting to Wazuh Indexer and Dashboards APIs.Wazuh agent is installed and shipping alerts to Wazuh Manager.Capturing mirrored packets and analyzing them.Pushed configurations to the OwlH NIDS node.Joined the OwlH NIDS node to the OwlH Manager.Interfaces defined for monitoring and auto-start.Downloaded and configured ruleset to be pushed to node(s).The Wazuh Manager will receive the logs and attempt to decode them and parse them for an alertable event.They can be configured to ingest any log and send to the Wazuh Manager.These are the endpoints to be monitored.Install Wazuh Agents on Servers and Desktops.Wazuh agent sends alert data to the SIEM.Zeek adds lots of metadata about packets.Suricata compares packets against a set of rules for anomalies.It runs the following applications to generate network event data.This is the network intrusion detection system.Keeping services running on the NIDS node(s).Pushing configurations to any registered NIDS node(s).You can also forward syslog to Wazuh for processing as well if you cannot install the agent on a host.The agents are HIDS which will forward event data to the SIEM.Agents are running on endpoints on our network.This is the SIEM that will collect the logs from any agents.A Wazuh Indexer API client that queries the database.A Wazuh API client that can control certain features in Wazuh.A web server that displays dashboards about alerts data.Wazuh Dashboards serves three purposes:.Configure the Wazuh Dashboards container.Any alerts that are picked up by Wazuh will be shipped here.This is the database where event data will be stored.Both switches are configured such that the ports where the IDS is plugged in are mirror ports and every other port will send a copy of every Ethernet frame to the IDS. The NIDS is connected to both VMBR0 and VMBR1.In our lab environment, we have already added some VLANs to VMBR1, because pfSense supports 802.1q. VMBR1 is the switch where all of the security and vulnerable infrastructure will be attached for further research.If you have a home router that supports 802.1q, then you could apply some VLAN segmentation to VMBR0 divide your VMs and containers into further subnets if desired.VMBR0 is the switch where all of your VMs and containers connected to your home network will be.This is a common configuration with Intrusion Detection Systems when you want to monitor all traffic on a network. Port mirroring is where we configure a switch to send a copy of every Ethernet frame to another port on the switch. Router with VLANs, Tagged Switched Ports, and Port Mirroring That way if an Ethernet frame contains a VLAN ID tag, the switch checks configured ports for the correct VLAN ID and MAC address. In this scenario, the switch tags the Ethernet frames with a VLAN tag for any configured switch ports. Router with VLANs and Configured Switch Ports However, none of the switch ports have been configured with VLAN ID tags. That way, the router and switch can work harmoniously to route packets if it receives an Ethernet frame that was tagged with a VLAN ID. In this scenario, we have configured some VLANs in the router. Router with VLANs Configured, Default Switch Configurations The DHCP server is enabled and no VLANs are configured. The router has the default private IP address range of 172.16.1.0/24. ![]() In this scenario, there is a router with a very simple, default configuration.
