How to use dsniff with Snort?

Here we will show you step by step how to use dsniff with Snort to improve the security of your network. Follow these simple steps:

1. Install Snort on your system:

• On Linux: Open a terminal and run the command “sudo apt-get install snort”.
• In Windows: Download the Snort installer from your site official and starts the installation process.

2. Configure Snort to accept traffic captured by dsniff:

• On Linux: Open the Snort configuration file located in “/etc/snort/snort.conf”. Find the line that contains “preprocessor frag3_global” and add the following line right below it: “preprocessor frag3_capture, preprocessor dcerpc2”. Save the changes.
• In Windows: Open the Snort configuration file located at “C:Snortetcsnort.conf” with a text editor. Find the line that contains “preprocessor frag3_global” and add the following line right below it: “preprocessor frag3_capture, preprocessor dcerpc2”. Save the changes.

3. Download and configure dsniff:

• On Linux: Open a terminal and run “sudo apt-get install dsniff” to install dsniff.
• In Windows: Download dsniff from its official website and start the installation process.

4. Run dsniff to capture network traffic:

• On Linux: Open a terminal and run the command “sudo dsniff -i [interface]”. Replace “[interface]” with the network interface you want to use, such as “eth0” or “wlan0.”
• In Windows: Open the dsniff application you installed and choose the network interface you want to use.

5. Monitor traffic captured by dsniff with Snort:

• On Linux: Open a new terminal and run the command “sudo snort -i [interface] -c /etc/snort/snort.conf”. Replace “[interface]” with the same network interface you used in the previous step.
• In Windows: Open Snort from the start menu and select the network interface you chose earlier.

6. Analyze the results and verify the security of your network:

• On Linux: While Snort is running, notifications will appear on the terminal if suspicious traffic is detected.
• In Windows: Snort will display alerts in its graphical interface if suspicious activity is detected.

Using dsniff with Snort, you will be able to capture network traffic and analyze it for malicious behavior. Remember that it is important to keep your network secure and always be aware of any unusual activity. Follow these steps and stay protected!
