2005/05/30 HenWen (Snort for Mac OS X)
© May 2005 Tony Lawrence
There's no reason that you can't just download and install Snort on Mac OS X. But if you don't want to install the development system,or never seem to have luck compiling from source, HenWen is a Mac GUI front end. As HenWen also includes a snort binary,you could also install HenWen just to get that and throw the rest of it away.
The GUI interface does have it's attractions, though. It's much easier to turn rules on and off with a click than to hunt them down in the /etc/snort/rules directory. It actually just presents the rules in the sections as they actually are in /HenWen.app/Contents/Resources/rules, and doesn't give you access to individual lines. You can add new rules easily enough, although you don't really write them here: you point HenWen at a text file you have created by some other means. Writing Snort rules is not the easiest task, and requires detailed knowledge of the protocols you are trying to watch, as well as knowledge of Snort's rule keywords and arguments. For most of us, that means we probably downloaded a rule someone else wrote. We'd then point HenWen at it.
For real-time alerts, HenWen includes an application called LetterStick, which normally runs as a daemon and appears as a small icon in your menu bar. If Snort triggers an alert, and HenWen is configured to log to LetterStick, an alert box will pop up on your console. It helpfully includes a 'What's This?' button which will take you to a Snort page that explains what the alert may mean.
If you just want to use snort directly, copy the binary from /Applications/HenWen.app/Contents and use it directly. Snort isn't particularly difficult to use - HenWen doesn't install a man page but there are plenty of on-line resources at https://www.snort.org if you prefer more direct control.

Synopsis
Security is a major issue in today’s enterprise environments. There are lots of tools available to secure network infrastructure and communication over the internet. Snort is a free and open source lightweight network intrusion detection and prevention system. Snort is the most widely-used NIDS (Network Intrusion and Detection System) that detects and prevent intrusions by searching protocol, content analysis, and various pre-processors. Snort provides a wealth of features, like buffer overflow, stealth port scans, and CGI attacks, just to name a few. Snort tries to detect malicious activity, denial of service attacks, and port scans by monitoring network traffic. It's divided into five major components: Packet decoder, Preprocessor, Detection engine, Logging and Alerting system, and Output modules.
Here, we will explain how to install from source, create a configuration file for Snort, create sample rules, and finally test on Ubuntu 16.04.
System Requirements
- Newly deployed Ubuntu 16.04 server.
- Minimum 4 GB RAM and multicore CPU for better performance.
- At least 1 TB hard disk.
Prepare the System for Deployment
Before starting, ensure your system is up to date and all installed software is running the latest version.
First, log in to root user and update your system by running the following command:
Install Required Dependencies
Before installing Snort, you will need to install required dependencies on your system.
You will also need to install DAQ. To do this, first download the latest version of DAQ with the following command:
Once the download is completed, extract the downloaded file with the following command:
Next, change the directory to
daq-2.0.6
:
Now run the following command to compile and install DAQ:
Install Snort from Source
You can install Snort from its source code or deb packages on Ubuntu. It is recommended to build Snort from source code, because the latest version of Snort may not be available in Linux distro repositories. Also note that the following examples use
eth0
for the network interface. Your main network interface may differ.
First, download the latest version of the Snort source code with the following command:
Once the download is completed, extract the downloaded file with the following command:
Change the directory to snort-2.9.8.3:
https://everchi780.weebly.com/my-passport-for-mac-drive-download.html. Then run the following command to compile and install Snort:
Next, you will need to update the shared libraries, otherwise you will get an error when you try to run Snort:
Next, create a symlink to the Snort binary:
Finally, you can verify the installation and configuration with the following command:
You should see the following output:
Configure Snort
You can configure Snort in three modes: Sniffer mode, Packet logger mode, and Network IDS mode. Here, we will configure Snort for Network IDS Mode.
Before configuring Snort, you will need to create a directory structure for Snort.
To do this, create the following directories and files:
Now set proper permission to the following directories:
Next, you will need to copy configuration files from Nnort source:
Change the directory to
snort-2.9.8.3
:
Then, copy
.conf
, .map
and .dtd
files to the /etc/snort/
directory:
https://everchi780.weebly.com/capture-one-pro-10-download-mac.html. You will also need to copy the dynamic preprocessors files:
Now we will edit the Snort configuration file. First, comment out all rulesets with the following command:
Next, open
/etc/snort/snort.conf
file in your favorite editor:
Change the file as shown below:
Save and close the file when you are done.
Next, validate the configuration file with the following command:
If everything is okay, you should see the following output:
Testing Snort
Snort is now ready for testing—but before starting, you will need to create a rule set.
How To Snort Properly
Let’s create a rule to test Snort.
Edit the
local.rules
file:
Add the following lines:
Save and close the file.
The above rules will generate an alert when someone tries to Ping, FTP, or Telnet to the server.
Now start Snort in Network IDS mode from the terminal and tell it to output any alert to the console:
Specification of all the options are listed below:
-A
console: Prints fast mode alerts to stdout-q
: Quiet mode. Don’t show banner and status report-c
: The path to our snort.conf file-i
: The interface to listen on
Now, since Snort is up and listening on interface
eth0
, so let’s try to Ping, FTP, and Telnet from remote machine.
On the remote machine run the following command:
Note:
192.168.15.189
is the IP address of Snort server
On the Snort server, you should see the output something like this:
You can stop Snort at any time by pressing
Ctrl+c
from your keyboard.
Create Snort Startup Script
You will also need to create a startup script to run Snort at boot time. You can do this by creating
snort.service
file:
Add the following lines:
Save the file, then enable the script to run at boot time:
