# Course #289: Ivre – Network Mapping and Vulnerability Assessment
## Section 1: Introduction to Ivre
Welcome to the first section of our comprehensive pentest course on Ivre, a powerful network mapping tool integrated with Kali Linux. In this section, we will delve into installation procedures, configuration settings, and practical usage of Ivre for network mapping and vulnerability assessment.
### What is Ivre?
Ivre is an open-source tool that enables security professionals to map networks and identify vulnerabilities using advanced algorithms and methodologies. It is built on top of Nmap and designed to provide in-depth scanning capabilities, resulting in detailed reports that can assist in strengthening the security posture of networks.
### Installation and Configuration on Kali Linux
#### Step 1: Update Your Kali Linux
Before installing any tool, it’s essential to update your Kali Linux system to ensure that you have the latest packages and security updates. Open a terminal and execute the following commands:
"`bash
sudo apt update
sudo apt upgrade -y
"`
#### Step 2: Install Ivre
Ivre is available in the Kali repository; however, it might not be the latest version. You can install it using the following command:
"`bash
sudo apt install ivre -y
"`
To ensure you have the latest features, you may also install Ivre from source. Follow these steps:
1. Install necessary dependencies:
sudo apt install git python3-pip python3-setuptools python3-wheel python3-requests python3-flask python3-cryptography nmap -y
2. Clone the Ivre repository:
git clone https://github.com/ivre/ivre.git
3. Navigate to the ivre directory:
cd ivre
4. Install Ivre using pip:
sudo pip3 install -r requirements.txt
#### Step 3: Configure Ivre
Before using Ivre, you need to configure it to suit your environment. Locate the configuration file typically found in `/etc/ivre.conf`, and edit it with your preferred text editor:
"`bash
sudo nano /etc/ivre.conf
"`
In this configuration file, set up parameters such as database connections, web server configurations, and any custom settings. Here’s an example of what to modify:
"`ini
[database]
type = sqlite
filename = /var/lib/ivre/ivre.db
[web]
host = 0.0.0.0
port = 5000
"`
Make sure to adjust the database filename and the host settings according to your setup.
### Step 4: Start the Ivre Service
Once you’ve configured Ivre, start the service:
"`bash
sudo python3 ivre.py
"`
This command will launch the Ivre service, making it available for use.
### Real-World Use Cases of Ivre
Ivre can be employed in various scenarios during pentesting engagements. Let’s discuss some real-world applications.
#### 1. **Network Scanning**
One of the primary uses of Ivre is to perform a comprehensive network scan. This can be executed with the following command:
"`bash
ivre scan –target
"`
Replace `
#### 2. **Vulnerability Assessment**
After identifying active devices, you can utilize Ivre to perform a vulnerability assessment. Use the following command:
"`bash
ivre vuln –target
"`
This will leverage various vulnerability databases to flag known security issues associated with services discovered during the scan.
#### 3. **Reporting and Documentation**
Once your scans and vulnerabilities have been identified, Ivre allows you to generate reports in various formats. For example, to create a PDF report, run:
"`bash
ivre report –format pdf –output report.pdf
"`
This is crucial for documenting findings and preparing for remediation discussions with stakeholders.
### Detailed Technical Explanations
In this section, we will cover the technical aspects of how Ivre functions, focusing on its integration with Nmap and various scanning methodologies.
#### Integration with Nmap
Ivre relies heavily on Nmap for its scanning capabilities. When you execute a scan via Ivre, it internally invokes Nmap with specific flags and options. This modular approach allows Ivre to extend Nmap’s capabilities by adding a layer of reporting and vulnerability checks.
Example command reflecting the internal Nmap call:
"`bash
nmap -sS -sV -O -p 1-65535
"`
This Nmap command performs a TCP SYN scan, version detection, and OS detection across all ports.
#### Scanning Methodologies
Ivre supports various scanning methodologies, which can be modified based on your engagement requirements. Some of the common methodologies include:
– **Ping Sweep:** Identifies live hosts in a target range.
– **Service Version Detection:** Determines types and versions of services running on open ports.
– **OS Fingerprinting:** Attempts to deduce the operating system of the devices.
By tweaking the parameters used in Ivre, you can customize your scans for efficiency or stealthiness, depending on the engagement’s goals.
