7. Follow the prompts to complete the installation.

Once installed, configure Nagios XI by accessing http://localhost/nagiosxi in your browser. Use the default credentials to log in and start setting up your monitoring environment.

Initial Reconnaissance

The first step in any hacking endeavor is Initial Reconnaissance. This step helps us gather valuable information. We will focus on scanning techniques and identifying open ports.

Scanning Techniques

Various techniques are used to scan a network. These techniques help in finding open ports and services. Here are some common ones:

• Nmap: A versatile tool for network scanning.
• Netcat: Known as the Swiss Army knife of networking.
• Masscan: Suitable for scanning large networks quickly.

We will focus on Nmap for our reconnaissance. It’s reliable and easy to use.

Identifying Open Ports

Identifying open ports is crucial. It reveals potential entry points into the system. Using Nmap, we can execute the following command:

nmap -sS -p 80 

This command performs a SYN scan on port 80. It checks if the port is open and listening.

Once we identify open ports, we can gather more details about the services running. For this, we use the following Nmap script:

nmap -sV -p 80 --script=http-enum 

This script helps in enumerating web services. It provides information about the server and applications running.
