What Is Vulnerability Mapping? (Protect Your Network Against Hackers)

What Is Vulnerability Mapping? Do you know how vulnerable your network is to hackers? You might not be able to see them, but they can still enter and destroy everything you’ve worked so hard for.

If this sounds familiar, then it’s time to get started with vulnerability mapping. Vulnerability mapping is a technique that helps detect security gaps in networks through active testing and scanning of systems and servers.

In this blog post, we will cover the basics of vulnerability mapping using Kali Linux as well as some things you can do to protect yourself from hackers!

There is no other time in history where you have been as vulnerable to cyberattacks than right now. With the power of Kali Linux, your knowledge on how hackers work can be transformed into a powerful weapon against them!

What Is Vulnerability Mapping?

What does vulnerability mapping entail? Vulnerability mapping entails security gaps detection through active testing and scanning of systems and servers for vulnerabilities that may put all aspects of company operations at risk

Who should know about it? You are not protected from these attacks without knowing what they’re doing- this post will give insight onto their methods

How do I get started with vulnerability mapping? Get ready by downloading an ISO image file (or installing via Live CD), then head off to start your own penetration test

What is vulnerability mapping and why should you care

Vulnerability mapping entails security gaps detection through active testing and scanning of systems and servers for vulnerabilities that may put all aspects of company operations at risk.

Companies today are on the lookout for new ways to gain insight into their networks, which is why vulnerability mapping should be part of your network protection strategy

Vulnerability mapping refers to the process of discovering and documenting instances in which vulnerabilities exist on your software, network, server environment or even your email account. 

To detect security gaps using active testing, you must first understand how an attacker might approach a system. This involves gathering as much information as possible about the attacker’s goals and methods so that you can do a risk analysis from the bottom up (starting with perimeter defense) to understand where you are most vulnerable.

Next assess those areas of vulnerability by running penetration tests against them to identify holes in your defenses. The result is detailed documentation about what vulnerabilities exist at every stage throughout the attack chain so that we can mitigate them quickly before they are discovered by someone intent on attacking us.

Kali Linux – the hacker’s best friend

Kali Linux is a powerful, free operating system that has various hacking tools for networks. Kali Linux is the go to OS for hackers and security professionals that need to get started with hands on practical tests.

Kali Linux comes with a large number of penetration testing tools that can be used for hacking networks, system administration tasks, information gathering in order to find vulnerabilities or create exploits (for use by white hat hackers), data recovery after deletion or encryption as well as many other things.

To get the most out of this distro, you need to get your hands dirty and start using it to test it and play around with its features. Theoretical knowledge will only get you so far without actual testing done by you.

Kali Linux has been around for a long time now, but it remains the hacker’s best friend. Kali Linux is a distribution of Linux that was designed for digital forensics and penetration testing

With so many tools built into its robust framework, this distro lets you test your network’s security with ease and accuracy in order to protect against hackers.

Kali Linux also includes an intuitive graphical interface which will make it far easier for some people to get started instead of wrestling with difficult commands and parameters. The importance of testing your network before a real attack happens.

Getting started with Kali Linux

Simply head over to their website and find the download that suits you. Kali Linux is based on Debian, which means that it’s compatible with most of, if not all the software packages you might be using.

Open your browser and go to their site where you can find downloads for Kali Linux in a variety of formats (ISO or Live USB).

Once downloaded, extract the content to an empty folder and then choose whether you want to write it to a physical medium such as a blank DVD, a USB thumb drive, or install it as a virtual machine.

As with any operating system, you need to know what kind of hardware it’s going on. Kali Linux is available in three different architecture types: x86 (32-bit), amd64 (64-bit) and ARMHF (hard float for ARM processors). The choice will depend upon the type of computer that you’re installing it on to.

Once you have installed the operating system you can start experimenting with the variuos tools that are now at your disposal.

How to use Nessus on Kali Linux for vulnerability mapping

Vulnerability mapping is the process of scanning your network for vulnerabilities. This includes finding the weak points in your system that would allow a hacker to gain access, and then plugging those holes so unauthorized users can’t get any further into your network than they’re able to go already. Kali Linux makes it easy to scan for these weaknesses using Nessus.

No more guess work with Nessus.

Nessus is a very popular vulnerability scanner, and will give you valuable insights into the nature of security on your network. This helps you to prepare yourself for any worst case scenarios.

Nessus will scan for a variety of common vulnerabilities.

The Nessus vulnerability scanner has a long history and wide usage in the penetration testing community. It’s able to find not only known bugs, but also ones that are unknown at the time of scanning.

This makes it an excellent tool for security professionals looking to stay on top of their game while learning about some of the most up to date threats that could find their way onto your network.

The importance of testing your network before a real attack

It’s not just about finding vulnerabilities. You want to be sure that you can fix them in the event they are exploited by someone else.

This is why Kali Linux was created–so that security professionals could have an open-source platform for exploring and identifying new threats, as a means to prevent them from ever being exploited.

Kali Linux is a hacker’s best friend and if you want to protect your network, it can help you know what vulnerabilities are out there so that you can fix them before they become an issue for your company or clients.

If testing reveals any issues with the security of your system, then it becomes much easier to shore up any lose ends before they become a vulnerability liability.

Tips for securing your network against hackers

Some of the most basic tips for protecting yourself from hackers include:

  • Keeping your software and operating system updated so that you know the latest fixes
  • Paying attention to what types of sites are being accessed on your network -and blocking any suspicious activity or questionable websites. It is also good practice to change passwords often, especially if they were used elsewhere online where a hacker might have gained access to.
  • Uninstalling unused services and applications .
  • Ensuring that any external access to your network is restricted and monitoring those ports for suspicious activity.
  • Using a firewall, like firewalls or iptables to block unwanted traffic before it enters your system. You can also use a site like Cloudflare which offers DDoS protection among other services.
  • Encourage regular password changes and make sure that your password policy is defined and enforced.
  • Regularly updating any operating systems on your devices, including your smartphone.
  • Ensuring that software is updated from the manufacturer’s website rather than third party sources to avoid malware or viruses injected at a point other than where it was designed to be installed.

These are great starting points, but there is a lot more to security than first meets the eye. That is why it is such a good idea to learn how Kali Linux can help you to investigate vulnerabilities on a network, especially your own.


We have taken a very quick and shallow dive into a very deep topic. It is my hope that this has been a useful starting point for you to get your head around the basic principles of vulnerability mapping.

I will be following up with more detailed posts on how to actually use Kali Linux in these scenarios, as well as what other tools might come in handy during penetration testing and vulnerability assessments.

The key take away from all of this should be that you don’t need to be a super genius or qualified computer scientist to use these tools. Instead, you need to have a passion for exploration and understanding, and a willingness to just get started.
