After create your account visit this to download the rules, I recommend download the last version on Snort v2.9 but you can chose your preferred rules package
Note
If you don’t create an account the page will block the links needed and you will see something like this:
Recommendations over download rules step
Windows defender block the rules package download
If Windows defender block your download turn off every antivirus this false positive is by the patterns of the Snort rules
VirusTotal false positive
If you check the package with VirusTotal you can see a False positive as here
Config NIDS
Setup Folders
Once extracted the folder from the compressed rules file you can see 4 folders
- etc
- preproc_rules
- rules
- so_rules
You can cut and paste this folder over the Legacy
folder in your Snort installation path, in my case «C:\Snort»
Then we will modify the «snort.conf» file stored in the «etc» folder
This folder is important to config some NIDS parameters and PATHs.
To facilitate the work I will leave you a modified version of the file here, you just should change the HOME_NET variable.
snort.conf manual config
We are going to open the file with some text editor, I recommend some text editor with line count to facilitate the process, I will use Sublime Text
We start setting the HOME_NET variable, this variable refers to the Network Section for monitoring
If you don’t know in which section is you computer just type «ipconfig» on your cmd
In my case y will use the 192.168.1.0/24 based on my Netmask and my computer IP
The Legacy
line of the HOME_NET variable look like this
Then look like this
Next setup the external network address EXTERNAL_NET
In this case will set every network address who isn’t the HOME_NET, to do it just will type !$HOME_NET
Legacy
New
Now we have to define the directory for our rules and preproc rules folder, the path of the folders are the same of the Snort installation folder plus the name of the corresponding folder. In this case:
- C:\Snort\rules
- C:\Snort\preproc_rules
For the case of the SO_RULE_PATH just we will add to the begin of the line a «#» to comment the line
Legacy
New
Once set the last variables, we have to setup the white list and black list path in the Snort rules folder in my case «C:\Snort\rules»
Legacy
New
Is essential set the log directory to store the logs, to do it we will uncomment this and add the path of your log folder, in my case «C:\Snort\log»
Legacy
New
Next we will set the path to dynamic preprocessors
«C:\Snort\lib\snort_dynamicpreprocessor»
Legacy
New
For dynamic preprocessor engine we will add the path and the .dll file in the path
«C:\Snort\lib\snort_dynamicengine\sf_engine.dll»
Legacy
New
We will comment this lines
We need change the decompress_swf { deflate lzma } to { deflate } like this
Legacy
New
Now we will convert ALL the forward slashes on $RULE_PATH/ to back slashes
Legacy
New
And the same to $PREPROC_RULE_PATH\ plus uncomment
Legacy
New
Finally in this file, take a look if «include threshold.conf» is in the last line and save
Windows 10
If you want to install Snort on Windows 10 you also need to do this steps
Else, your config is done
We need rename the white_list.rules to white.list, black_list.rules to black.list, change the forward slash to back slash and uncomment the lines
Legacy
New
Open a cmd on your Snort rules folder and create a file named white.list and black.list, this will be your files referred before. to do it you can use
C:\Snort\rules type nul > white.list C:\Snort\rules type nul > black.list
And now open each file with your text editor and
For white.list add this line
save and close
And in the black.list add
save and close
Test config
once you have your configuration ready is time to test them
use
to show all your interfaces, and search your computer IP, in my case is the interface 9
Once having your interface number we proceed to use
C:\Snort\bin\snort -i 9 -c C:\Snort\etc\snort.conf -T
If everything goes right, you should see a large output and this on the bottom

Download Snort 2 for Windows 7, 8, 10, 11 — An Open Source network intrusion prevention system capable of performing real-time traffic analysis and packet logging on IP networks
Snort is the foremost Open Source Intrusion Prevention System (IPS) in the world. Snort IPS uses a series of rules that help define malicious network activity and uses those rules to find packets that match against them and generates alerts for users.
Snort can be deployed inline to stop these packets, as well. Snort has three primary uses: As a packet sniffer like tcpdump, as a packet logger — which is useful for network traffic debugging, or it can be used as a full-blown network intrusion prevention system. Snort can be downloaded and configured for personal and business use alike.
Uses:
- Snort’s open-source network-based intrusion detection/prevention system (IDS/IPS) has the ability to perform real-time traffic analysis and packet logging on Internet Protocol (IP) networks. Snort performs protocol analysis, content searching and matching.
- The program can also be used to detect probes or attacks, including, but not limited to, operating system fingerprinting attempts, semantic URL attacks, buffer overflows, server message block probes, and stealth port scans.
- Snort can be configured in three main modes: 1. sniffer, 2. packet logger, and 3. network intrusion detection.
