# Installation

![](https://i.imgur.com/4prSZg1.png)

We will be installing Nessus on a Local Kali VM.

Other OS's **will not** be covered in this walkthrough, in which case the official installation guide can be found below. 

&#x20;<https://docs.tenable.com/nessus/Content/GettingStarted.htm><br>

### **Step #1**

Goto <https://www.tenable.com/products/nessus/nessus-essentials> and register an account.

**You will need to do this for an activation code.**&#x20;

### **Step #2**<br>

We will then download the Nessus-#.##.#-debian6\_**amd64.**&#x64;eb file

Save it to your **/Downloads/** folder&#x20;

### Step #3<br>

In the terminal we will navigate to that folder and run the following command:<br>

sudo dpkg -i **package\_file.deb**

Remember to replace package\_file.deb with the file name you downloaded.

We will now start the Nessus Service with the command:<br>

**sudo /bin/systemctl start nessusd.service**

Open up Firefox and goto the following URL:<br>

You may be prompted with a security risk alert.

Click **Advanced...** -> **Accept the Risk and Continue**

Clicking the **Skip** button will bring us to a page, which we will input that code we got in the email from Nessus. \

### Step #8<br>

Nessus will now install the **plugins** required for it to function.

This will take some time, which will depend on your internet connection and the hardware attached to your VM.

If the progress bar appears to be **not moving**, it means you do not have **enough space** on the VM to install.  &#x20;

### **Step #9**

**Log in** with the account credentials you made earlier. \
