Introduction My setup has changed pretty significantly from my original pfSense guide and I wanted to update it reflect some of those improvements. The changes include:- Based on pfSense 2. Increased security via improved firewall rule sets Replaced Apple Airport wifi access points with Ubiquiti Unifi enterprise wifi access points use of multiple VLANs to segregate traffic between the various networks rather than relying on multiple NICs. This is a slightly more lengthy and complicated setup than the previous guide but I think the trade offs are worth it. Requirements My home and office has grown to require more than just the two local networks my previous guide afforded me. I now require the following isolated segments and primarily this drove my decision to move to a VLAN based setup. Used primarily by visitors who require internet access but also acts as a backup if AirVPN goes down for any reason.
The first task that needs to be completed though is some explanations on what is going to happen once pfBlockerNG is configured properly. The next settings are to set the DNS listening port normally port 53 , setting the network interfaces that the DNS resolver should listen on in this configuration, it should be the LAN port and Localhost , and then setting the egress port should be WAN in this configuration.
The next step is the first step in configuration of pfBlockerNG specifically. This IP needs to be in the private network range and not a valid IP on the network in which pfSense is being used. For example, a LAN network on This IP will be used to gather statistics as well as monitor domains that are being rejected by pfBlockerNG.
The two options are manual feeds from other web pages or EasyLists. Again these are all user preference and multiple can be selected if desired.
This will run through a series of web downloads to obtain the block lists selected on the EasyList configuration page earlier. Anytime changes are made lists added or removed be sure to run this step.
In promiscuous mode, the NIDS can eavesdrop on all communications on the network segment. NIDSs which monitors network traffic for particular network segments or devices and analyzes the network and application protocol activity to identify suspicious activity.
It can identify many different types of events of interest. The advantage of a NIDS is that it has no impact on the systems or networks it is monitoring.
The units have been placed on strategic network segments and can monitor network traffic for all devices on the segment as illustrated in Figure 2. The use of multiple NIDS within a network is an example of a defense-in-depth security architecture.
HIDSs is which monitors the characteristics of a single host and the events occurring within that host for suspicious activity.
Examples of the types of characteristics a host-based IDPS might monitor are network traffic only for that host , system logs, running processes, application activity, file access and modification, and system and application configuration changes. Host-based IDSs are most commonly deployed on critical hosts such as publicly accessible servers and servers containing sensitive information.
Figure 3 depicts a network using a HIDS on specific servers and host computers. As previously mentioned, the ruleset for the HIDS on the mail server is customized to protect it from mail server exploits, while the Web server rules are tailored for Web exploits. One of the main advantages of analyzing events using DIDS is to be able to observe system-wide, entire network system and specific host.
But there are three common primary classes of detection methodologies: signature- based, anomaly-based, and stateful protocol analysis.
Most IDS technologies use multiple detection methodologies, either separately or integrated, to provide more broad and accurate detection. Signature- based detection is the process of which compares known threat signatures to observed events to identify incidents.
This is very effective at detecting known threats but largely ineffective at detecting unknown threats and many variants on known threats. Signature-based detection cannot track and understand the state of complex communications, so it cannot detect most attacks that comprise multiple events. Signature-based detection is the simplest detection method because it just compares the current unit of activity, such as a packet or a log entry, to a list of signatures using string comparison operations.
Signature-based detection technologies have little understanding of many network or application protocols and cannot track and understand the state of complex communications. This method uses profiles that are developed by monitoring the characteristics of typical activity over a period of time.
The IDS then compares the characteristics of current activity to thresholds related to the profile. Anomaly-based detection methods can be very effective at detecting previously unknown threats. Common problems with anomaly-based detection are inadvertently including malicious activity within a profile, establishing profiles that are not sufficiently complex to reflect real-world computing activity, and generating many false positives. Unlike anomaly-based detection, which uses host or network-specific profiles, stateful protocol analysis relies on vendor-developed universal profiles that specify how particular protocols should and should not be used.
This is commonly used with wireless hot spots, or as an additional layer of protection for wireless networks with authentication against a local user database, or external RADIUS server such as Microsoft Active Directory. You can use these options to connect roaming users for remote access, or site to site connectivity to connect multiple locations. Multi-WAN multiple Internet connections with failover and load balancing are supported. In combination with a VLAN capable switch, you can connect numerous Internet connections over a single physical interface on the firewall.
This is especially helpful if you want to access services like VPN remotely. Wireless with a wireless kit available from Netgate, your m1n1wall can act as a wireless access point, or be used in Ad-hoc networks.
It can also connect to a wireless access point as a client use your neighbors wireless as a second WAN with permission, of course , amongst many other possible deployments.
