On Manjaro, the command we need is not the usual pacman , it is pamac. There are a few steps to complete before we can run Snort. To make sure your copy of Snort is providing the maximum level of protection, update the rules to the most recent version. This ensures Snort has access to the newest set of attack definitions and protection actions. If you have registered and obtained your own oinkcode , you can use the following command to download the rule set for registered users.
The Snort download page lists the available rule sets, including the community rule set for which you do not need to register. We want Snort to detect suspicious network traffic addressed to any device on the network, not just network traffic that happens to be sent to the computer on which Snort is installed.
The following command will cause network interface enp0s3 to operate in promiscuous mode. Substitute enp0s3 with the name of the network interface you are using on your computer. If you are running Snort in a virtual machine, also remember to adjust the settings in your hypervisor for the virtual network card used by your virtual machine. Snort scrolls a lot of output in the terminal window, then enters its monitoring an analysis mode. From another computer, we started to generate malicious activity that was directly aimed at our test computer, which was running Snort.
Snort identifies the network traffic as potentially malicious, sends alerts to the console window, and writes entries into the logs. This probably indicates that someone is performing reconnaissance on your system.

General Configuration What interface should snort listen on? This user and group should have very few privileges. But the more logging options use you, the slower Snort will run.
Where should Snort log? After clicking the add interface button, you will see the interface settings page. The settings page contains a lot of options, but there are only a few you really need to worry about to get things up and running. If you are running a multi-wan router , you can go ahead and configure the other WAN interfaces on your system.
I also recommend adding the LAN interface. Before you start the interfaces, there are a few more settings that need to be configured for each interface. To configure the additional settings, go back to the Snort interfaces tab and click the 'E' symbol on the right side of the page next to the interface. This will take you back to the configuration page for that particular interface. Click the edit button next to the interface to change additional settings.
To select the rule categories that should be enabled for the interface, click on the categories tab. All of the detection rules are divided into categories. Categories containing rules from Emerging Threats will begin with 'emerging,' and rules from Snort. Select the detection rule categories that you want to enable.
By dividing the rules into categories, you can enable only the particular categories you are interested in. I recommend enabling some of the more general categories.
If you are running specific services on your network such as a web or database server, then you should enable categories pertaining to them as well. It's important to remember that Snort will require more system resources each time an additional category is turned on. This can also increase the number of false positives, as well. In general, it's best to turn on only the groups you need, but feel free to experiment with the categories and see what works best.
If you want to find out what rules are in a category and learn more about what they do, then you can click on the category. This will link you directly to the list of all rules within the category.
Detects signatures of known trojans, viruses, and worm. It is highly recomended to use this category. There are a few settings on the preprocessors settings page that should be enabled. Many of the detection rules require HTTP inspect to be enabled in order for them to work. Installation seems very involved. According to winsnort , how did you complete the install? Other IT personal is not really versed in linux, that's why I'm doing this on windows 10 machine in a way that will be easy to explain as much as you can easily explain console run software.
So no WSL. I get enough blank stares from non-IT staff Install is easy, here is lovely step by step direction I found and followed. Have you installed Npcap? You need to download it from here.
I did, several versions, each one failed. I started with Winpcap, and then went to npcap, latest stable version. The problem is there, because ncap gives up the moment when realizes that computer is using wifi. I'm annoyed, but I will try to connect computer with wires and see will that help. Currently waiting for arrival of long enough wire. Seems like Murphy has a field day with me
