# Kismet Pentest Course: Section 1/5 – Introduction

## Introduction to Kismet

Kismet is a powerful wireless network detector, sniffer, and intrusion detection system. It works on various platforms, including Linux, and is predominantly used for wireless penetration testing. With Kismet, security professionals can discover networks, analyze traffic, and detect vulnerabilities within wireless systems. This course section will guide you through the installation and configuration of Kismet on Kali Linux, its usage, and real-world applications.

## 1. Installation and Configuration on Kali Linux

### 1.1 Prerequisites

Before installing Kismet, ensure that your Kali Linux installation is up to date. You can do this by running the following command in your terminal:

"`bash
sudo apt update && sudo apt upgrade -y
"`

### 1.2 Installing Kismet

Kismet can be installed from the Kali Linux repositories. Follow these steps:

1. **Open Terminal**: Access your Kali Linux terminal.
2. **Install Kismet**: Execute the following command:

   sudo apt install kismet -y

 

3. **Verify Installation**: Check if Kismet is installed by typing:

   kismet

 

If Kismet launches successfully, the installation was successful.

### 1.3 Configuration

Kismet requires some configuration before it can be used effectively. The configuration file is typically located at `/etc/kismet/kismet.conf`. You can edit this file with your preferred text editor, for example:

"`bash
sudo nano /etc/kismet/kismet.conf
"`

**Key Configuration Settings:**

– **Source Configuration**: Define which wireless interfaces Kismet will use. For example, if you want to use the `wlan0` interface, add the following line:

[/dm_code_snippet]
source=nl80211,wlan0
[/dm_code_snippet]

– **Kismet Server Settings**: Set the port and other server options here. The default port is `2501`.

– **Logging Options**: You may want to specify where Kismet should log its output.

Save the file after making the necessary changes, and exit the text editor (for nano, press `CTRL + X`, then `Y`, and `Enter`).

## 2. Step-by-step Usage of Kismet

### 2.1 Starting Kismet

To start Kismet, run the following command in your terminal:

"`bash
sudo kismet
"`

Alternatively, you can run it in the server mode, which is useful if you want to access Kismet via a web interface:

"`bash
sudo kismet_server
"`

### 2.2 Accessing Kismet Web Interface

Once Kismet is running, you can access it through a web browser. Open your browser and navigate to:

"`
http://localhost:2501
"`

You should see the Kismet web interface, which provides a comprehensive dashboard for monitoring wireless traffic.

### 2.3 Discovering Networks

#### Step 1: Network Discovery

As Kismet runs, it will automatically start capturing wireless packets. The Kismet interface will display the detected networks in real-time. Each network will show information such as:

– SSID (Service Set Identifier)
– Signal strength
– Channel
– Encryption type

#### Step 2: Analyze Network Traffic

Click on any detected network to view detailed statistics. You will be able to see connected clients, traffic patterns, and more.

### 2.4 Real-World Use Cases of Kismet

#### Use Case 1: Detecting Unauthorized Access Points

Kismet can be used to detect rogue access points that may be set up within the network. By analyzing the SSIDs and MAC addresses, security professionals can identify unauthorized devices.

#### Use Case 2: Monitoring Network Performance

Kismet’s ability to monitor wireless traffic allows administrators to identify congestion points in the network, leading to better network performance and optimization.

#### Use Case 3: Wireless Penetration Testing

During penetration tests, Kismet can be utilized to gather information on networks and clients. This information can then be used to identify vulnerabilities, such as weak encryption protocols.

## 3. Detailed Technical Explanations

### 3.1 Kismet's Architecture

Kismet operates using a modular architecture, which allows it to support a wide range of wireless drivers and protocols. The Kismet server captures packets and processes them through various modules for detection and analysis.

### 3.2 Packet Capture Mechanism

Kismet uses a combination of packet capture libraries, such as `libpcap`, to intercept wireless packets. Understanding how Kismet captures packets will help in troubleshooting and optimizing your setup.

### 3.3 Advanced Configuration Options

For advanced users, Kismet offers several additional configuration options, such as:

– **GPS Integration**: For tracking the location of wireless signals.
– **Packet Filtering**: To limit the types of traffic being captured based on specific criteria like SSID or MAC addresses.
– **Data Export**: Exporting captured data in different formats for further analysis.
