cd nagios-<version>
./configure --with-command-group=nagcmd
make all
sudo make install

5. Install Plugins:

• Download and install Nagios plugins:

wget https://nagios-plugins.org/download/nagios-plugins-<version>.tar.gz
tar -xvzf nagios-plugins-<version>.tar.gz
cd nagios-plugins-<version>
./configure
make
sudo make install

6. Start Nagios Service:

sudo systemctl start nagios
sudo systemctl enable nagios

7. Access Nagios Web Interface:

• Open your browser and navigate to http://<your_server_ip>/nagios.
• Log in using the default credentials and configure monitoring.

Basic Tutorials of Nagios: Getting Started

1. Adding a Host to Monitor:

• Define a new host in the nagios.cfg file:

define host {
  use         linux-server
  host_name   example-server
  alias       Example Server
  address     192.168.1.100
}

2. Setting Up a Service Check:

• Add a service definition to monitor a specific resource:

define service {
  use                 generic-service
  host_name           example-server
  service_description CPU Load
  check_command       check_nrpe!check_load
}

3. Configuring Alerts:

• Define notification settings in the contacts.cfg file:

define contact {
  contact_name        admin
  email               admin@example.com
  service_notification_commands notify-service-by-email
}

4. Using NRPE for Remote Checks:

• Install NRPE on the remote system: sudo apt install nagios-nrpe-server

sudo apt install nagios-nrpe-server

• Configure nrpe.cfg to define remote checks.

5. Creating Custom Plugins:

• Write a custom plugin script:

#!/bin/bash
if [ "$(df / | tail -1 | awk '{print $5}' | sed 's/%//')" -gt 80 ]; then
    echo "CRITICAL: Disk usage is above 80%"
    exit 2
else
    echo "OK: Disk usage is normal"
    exit 0
fi

• Save the script in /usr/local/nagios/libexec.

How Nessus Works and Its Architecture

Nessus is another popular tool for vulnerability scanning and security assessment. Its architecture includes:

1. Nessus Server: The core engine that scans the network and processes data.
2. Nessus Agents: Lightweight tools installed on hosts for in-depth local scanning.
3. Policy Creation: Users define scan policies for specific environments.
4. Scan Execution: The server interacts with agents or directly scans targets.
5. Reporting: Detailed reports are generated post-scan for analysis.

The system works by running preconfigured or custom scripts on the target systems to identify vulnerabilities.
