Every IT infrastructure offers points of attack that hackers can use to steal and manipulate data. Only one thing can prevent these vulnerabilities from being exploited by unwelcome guests: You need to preempt the hackers and identify and close the gaps. Kali Linux can help.
To maintain the security of a network, you need to check it continuously for vulnerabilities and other weak points through penetration testing. You have a clear advantage over attackers because you know the critical infrastructure components, the network topology, points of attack, the services and servers executed, and so on. Exploitation tests should look for vulnerabilities in a secure, real environment, so you can shut down any vulnerabilities found – and you need to do this over and over again.
The variety of IT components dedicated to security does not make selecting a suitable tool any easier, because all possible attack vectors need to be subjected to continuous testing. Kali Linux  meets these requirements – and does much more.
Kali Linux at a Glance
The Debian-based Kali Linux distribution is at the heart of most penetration testing systems. …
Kali Linux is particularly resource-friendly and can be run in a virtual machine, so any notebook can become a full-fledged penetration test system with very little effort. Most administrators are familiar with classics like Wireshark and Nmap, so I will focus on the less common applications.
Penetration testing begins with an overview of the infrastructure and then searches for specific weak points. To do this, you first use a security scanner. Depending on their nature and type, these tools are capable of checking entire networks or individual systems or applications for known weak points.
