== Prerequisites ==
Before starting the installation, ensure that your system meets the following requirements:
* Ubuntu 24.4 server (or any other compatible Ubuntu version)
* Root privileges or sudo access
* A working internet connection for downloading dependencies
* Sufficient disk space for OSSIM components and data storage

== Configuration and Setup ==
After installation, you must configure OSSIM for proper operation. Follow these steps to complete the configuration:

=== Network Configuration ===
OSSIM requires proper network setup, including configuring the system's IP address, subnet, and gateway. Edit the network interfaces file using:

<nowiki>
sudo nano /etc/network/interfaces</nowiki>

Example configuration for static IP:

<nowiki>
iface eth0 inet static
address 192.168.1.100
netmask 255.255.255.0
gateway 192.168.1.1</nowiki>

Once the network configuration is updated, restart the networking service:

<nowiki>
sudo systemctl restart networking</nowiki>

=== Firewall Configuration ===
Ensure that the necessary ports are open for communication between OSSIM components and other services:

<nowiki>
sudo ufw allow 443/tcp
sudo ufw allow 22/tcp
sudo ufw allow 1514/udp
sudo ufw allow 514/udp</nowiki>

Verify that the firewall settings are applied correctly:

<nowiki>
sudo ufw status</nowiki>

=== Database Configuration ===
OSSIM uses MySQL for its database. Make sure that MySQL is installed and properly configured before running OSSIM:

<nowiki>
sudo apt update
sudo apt install mysql-server</nowiki>

After installation, secure your MySQL installation:

<nowiki>
sudo mysql_secure_installation</nowiki>

Create a dedicated MySQL user and database for OSSIM:

<nowiki>
sudo mysql -u root -p
CREATE DATABASE ossim;
CREATE USER 'ossim'@'localhost' IDENTIFIED BY 'yourpassword';
GRANT ALL PRIVILEGES ON ossim.* TO 'ossim'@'localhost';
FLUSH PRIVILEGES;
EXIT;</nowiki>

=== System Tuning ===
For optimal performance, tune your system to handle the high demands of logging and alert processing. Adjust the following parameters in `/etc/sysctl.conf`:

<nowiki>
fs.file-max = 100000
net.ipv4.ip_local_port_range = 1024 65535</nowiki>

Apply the changes:

<nowiki>
sudo sysctl -p</nowiki>

=== OSSIM Configuration ===
Now that the system is set up, you need to configure OSSIM. The main configuration file for OSSIM is located at `/etc/ossim/ossim.conf`. Edit this file to adjust key parameters such as database connection, logging level, and network settings.

Example:

<nowiki>
nano /etc/ossim/ossim.conf</nowiki>

Set the database user and password:

<nowiki>
DB_USER=ossim
DB_PASS=yourpassword</nowiki>

After making the changes, restart OSSIM:

<nowiki>
sudo systemctl restart ossim</nowiki>

=== Web Interface Access ===
The OSSIM web interface is typically hosted on port 443 (HTTPS). To access the OSSIM interface, open a browser and navigate to:

<nowiki>
https://<your_server_ip>/ossim</nowiki>

Log in using the default credentials:

<nowiki>
Username: admin
Password: admin</nowiki>

Once logged in, you can customize your dashboards, configure additional plugins, and set up monitoring and alerting systems as needed.

== Troubleshooting ==
In case of issues during installation or configuration, here are some common solutions:

* **Database connection issues**: Verify that the MySQL server is running and that the database user has correct privileges.
* **Service startup failures**: Check system logs using `journalctl` or the specific OSSIM service logs located in `/var/log/ossim/` to identify any issues.
* **Firewall problems**: Ensure all required ports are open and accessible.

To view real-time logs for OSSIM services:

<nowiki>
sudo journalctl -u ossim</nowiki>
