# Kali Linux Course #636: Using the Tiger Tool
## Section 1: Introduction to Tiger
In the realm of penetration testing and network security auditing, having the right tools at your disposal is paramount. One such tool is **Tiger**, a security auditing tool designed to assess the security of Unix and Linux systems. In this section, we will delve into the installation, configuration, and practical usage of Tiger on Kali Linux, ensuring you are well-equipped to conduct thorough security assessments.
### Overview of Tiger
Tiger is a security auditing tool that performs system checks based on predefined checks and policies. It can detect various security vulnerabilities, misconfigurations, and non-compliance with security policies. The tool generates comprehensive reports, making it easier for security professionals to identify and remediate vulnerabilities.
While Tiger was initially designed for Unix systems, its capabilities are highly applicable to Linux distributions, particularly those used in penetration testing environments like Kali Linux.
## Installation and Configuration on Kali Linux
### System Requirements
Before installing Tiger, ensure that your Kali Linux system meets the following requirements:
– An up-to-date version of Kali Linux
– Sufficient user permissions (you may need root or sudo access)
### Installation
1. **Open Terminal**: Access your terminal window in Kali Linux.
2. **Update Package List**: It’s always a good practice to ensure that your package list is up to date. Run the following command:
sudo apt update
3. **Install Tiger**: Use the package manager to install Tiger:
sudo apt install tiger
Once installed, verify that Tiger is installed correctly by checking the version:
"`bash
tiger –version
"`
### Configuration
Tiger uses configuration files to define the types of checks it will perform. The default configuration is usually sufficient for basic audits, but you may want to customize it to meet specific requirements.
1. **Edit the Configuration File**: The main configuration file is located at `/etc/tiger/tigerrc`. You can edit this file using a text editor:
sudo nano /etc/tiger/tigerrc
2. **Customize Checks**: Within this file, you can enable or disable specific checks and customize various parameters. Look for lines starting with `#` to uncomment and modify them.
3. **Test Configuration**: After editing, ensure that the configuration is syntactically correct. You can use the following command to validate:
sudo tiger –test
### Running Tiger
To run Tiger, simply execute the following command:
"`bash
sudo tiger
"`
By default, Tiger will perform a comprehensive audit based on the configuration settings.
### Output Analysis
Tiger generates reports in the `/var/log/tiger` directory. You can view the reports using the `cat` or `less` commands:
"`bash
less /var/log/tiger/tiger.log
"`
This log file contains detailed information about the checks performed and any vulnerabilities identified.
## Step-by-Step Usage and Real-World Use Cases
### Basic Usage
Once you are comfortable with the installation and configuration, using Tiger becomes straightforward. Follow these steps to perform a security audit:
1. **Perform a Basic Audit**:
sudo tiger
This command initiates a full audit of your system.
2. **View the Reports**: After completion, check the log files located in `/var/log/tiger`.
### Advanced Usage Scenarios
#### 1. Automated Security Audits
In a corporate environment, you may need to perform regular security audits. You can automate Tiger by scheduling it to run at specific intervals using cron jobs.
1. **Open Crontab**:
sudo crontab -e
2. **Add a New Cron Job**: For example, to run Tiger every Sunday at 2 AM, add the following line:
0 2 * * 0 /usr/bin/tiger
#### 2. Custom Checks
Suppose you have a specific security policy that requires checks for unauthorized users. You can create a custom check by editing the configuration:
1. **Edit Configuration**:
sudo nano /etc/tiger/tigerrc
2. **Add a Check for Unauthorized Users**: Uncomment or add the following line:
check_users=true
This allows Tiger to specifically check for unauthorized user accounts during its audit.
### Real-World Use Cases
1. **Compliance Audits**: Organizations often need to comply with various regulations (e.g., PCI-DSS, HIPAA). Use Tiger to ensure that configurations meet compliance standards.
2. **Pre-Deployment Security Assessments**: Before deploying new servers, run Tiger audits to ensure that proper security configurations are in place.
3. **Forensic Analysis**: In the event of a security breach, use Tiger to analyze system configurations and identify potential vulnerabilities that may have been exploited.
## Detailed Technical Explanations
### How Tiger Works
Tiger operates by executing a series of predefined scripts that assess the security state of your system. Each script performs specific checks, such as:
– Verifying file permissions
– Checking for default passwords
– Assessing user accounts and their privileges
– Reviewing system logs for unauthorized access attempts

### Code Examples
Here are some code snippets to give you practical examples of how to use Tiger in your audits.
#### Running Tiger with Specific Checks
"`bash
sudo tiger –checksome
"`
This command runs Tiger with checksum verification to detect file alterations.
#### Generating a Custom Report
To create a report in a specific format, you can use:
"`bash
sudo tiger –report-format=html > my_tiger_report.html
"`
This command generates an HTML report that can be shared with stakeholders or management.
## Conclusion
In this section, we explored the powerful capabilities of the Tiger tool for conducting comprehensive security audits on Kali Linux. By following the installation and configuration steps, you can effectively utilize Tiger to identify vulnerabilities and enhance your organization's security posture.
As you continue your journey in penetration testing, remember that tools like Tiger are essential in maintaining a robust security framework. In the subsequent sections, we will explore more advanced tools and techniques in the world of cybersecurity.
