### 3. Usage and Real-World Use Cases
Legion provides various functionalities for penetration testing through a clean and intuitive GUI. Let's walk through the process of using it step-by-step.
#### 3.1 Step-by-Step Usage
1. **Launching legion$**
Launch the tool by typing `legion` in the terminal or navigating to it in the applications menu.
2. **Creating a New Project**
– Click on **New Project**.
– Enter a name for your project and define the target range (IP addresses or subnets).
3. **Adding Targets**
– Click on **Targets** in the sidebar.
– Use the **Add Target** option to input individual IPs or ranges.
– As a best practice, categorize your targets by application type or environment.
4. **Scanning for Vulnerabilities**
– Select your target(s) from the list.
– Choose **Scan** from the menu and select the type of scan you want to perform (e.g., simple, full).
– Legion will begin scanning the targets, using a combination of various scanning techniques.
5. **Analyzing Results**
– Upon completion of the scan, navigate to the **Results** tab.
– Legion will display the identified vulnerabilities, categorized by severity.
– For each vulnerability, click to view details and suggestions for remediation.
6. **Generating Reports**
– Click on **Reports** in the sidebar.
– Select **Generate Report**.
– Choose the format, such as PDF or HTML, to export your findings for further analysis or client deliverables.
### 4. Real-World Use Cases
#### 4.1 Network Penetration Testing
Legion can be used in a variety of scenarios. One common use case is performing an internal network penetration test. By scanning the network for vulnerabilities, you can identify security gaps that need to be addressed.
– **Example: Internal Network Scan**
Assume you are tasked with assessing the security of a corporate network. You would start by adding the network range to legion$, allowing you to map connected devices and their vulnerabilities.
#### 4.2 Web Application Testing
Legion can also be used for scanning web applications to identify potential vulnerabilities such as SQL injections, XSS, and other common threats.
– **Example: Web Application Vulnerability Assessment**
When assessing a web application, you would configure legion$ to scan the application’s IP and perform specialized web vulnerability scans, analyzing the results for critical findings that need to be worked on.
#### 4.3 External Security Assessment
Another use case involves conducting an external security assessment for clients. By scanning their public-facing IP addresses, you can discover vulnerabilities that could be exploited by attackers.
– **Example: Public-Facing Services Scan**
Input the public IP or range into legion$, perform your scans, and provide a detailed report highlighting risks and remediation strategies.
### 5. Detailed Technical Explanations
Legion is built on several underlying technologies that make its operations efficient and effective. Here we will cover some critical components.
#### 5.1 Enumeration Techniques
Legion employs various enumeration techniques to gather information about the target systems. This includes:
– **Port Scanning**: Identifies which ports are open on a target machine.
– **Service Version Detection**: Determines the software and version running on open ports.
#### 5.2 Vulnerability Databases
Legion uses various vulnerability databases to match its findings against known vulnerabilities, such as:
– NVD (National Vulnerability Database)
– CVE (Common Vulnerabilities and Exposures)
By leveraging these databases, legion$ can provide accurate and up-to-date information on vulnerabilities associated with found services.
