<s>[INST] Using wireshark as a tool for hardening my network. I need a step by step list of how to use it to produce a list of vulnerabilities then address them. [/INST] Wireshark is a powerful packet analyzer, but it's not specifically designed for vulnerability scanning or network hardening. However, you can use it to analyze your network traffic and gather information that could help you identify potential vulnerabilities. Here's a step-by-step guide on how to use Wireshark for this purpose:

1. Install and run Wireshark on a computer connected to your network.
2. Select the network interface you want to capture traffic from.
3.  Start the capture and let it run for a while (e.g. 30 minutes or more) to get a good sample of traffic.
4. Stop the capture and analyze the traffic to identify any suspicious activity or anomalies. Look for unusual patterns, strange protocols or unexpected traffic sources.
5. Once you have identified potential vulnerabilities, research them further to understand the root cause and potential solutions.
6. Implement appropriate mitigation strategies to address the vulnerabilities you have identified. This could include changes to your network configuration, software patches or upgrades, or employee training.</s>
