Introduction to Penetration Testing with Kali Linux

Penetration testing with Kali Linux is a powerful way to assess the security of your systems and networks. As a beginner, getting started with penetration testing with Kali Linux can seem daunting, but with the right guidance, you can set up a home lab and conduct basic vulnerability assessments.

Setting Up a Home Lab

To get started with penetration testing, you need to set up a home lab. This can be done using virtual machines or physical devices. You will need to install Kali Linux, which is a Linux distribution specifically designed for penetration testing.

Key Components of a Home Lab

Kali Linux
Virtual machine software (e.g. VirtualBox)
Test network or devices

Conducting Basic Vulnerability Assessments

Once you have set up your home lab, you can start conducting basic vulnerability assessments. This involves using tools such as Nmap and OpenVAS to scan for open ports and identify potential vulnerabilities.

nmap -sV 192.168.1.100

Example Output

Starting Nmap 7.80 ( https://nmap.org ) at 2023-02-20 14:30 EST
Nmap scan report for 192.168.1.100
Host is up (0.0020s latency).
Not shown: 995 closed ports
PORT      STATE SERVICE    VERSION
21/tcp    open  ftp        vsftpd 3.0.3
22/tcp    open  ssh        OpenSSH 7.9p1 Ubuntu 10 (Ubuntu Linux; protocol 2.0)
80/tcp    open  http       Apache httpd 2.4.41 ((Ubuntu))
Service detection performed. Please report any incorrect results at https://nmap.org/submit/ .
Nmap done: 1 IP address (1 host up) scanned in 6.45 seconds
