Building a Security Lab in VirtualBox

In this post, we we will take a look at an in-detail process of setting up an entry-level cybersecurity lab using VirtualBox

pfSense is stuck at configuring WAN interface

• Make sure you’re bridged to the Internet-connected interface

My Internet-facing VMs can’t get out to the Internet

• Make sure pfSense is running (should always be the first to boot)
• Make sure pfSense is bridged to the Internet-connected interface
• Is your VM on the right LAN?
• Check your firewall rules in pfSense

My VM’s screen is tiny

• Go to View > Virtual Screen > Turn up the scaling
• Or, try changing the view to Scaled Mode (won’t work for all VMs)

When I try to ping Kali’s DNS name I get its old IP address

• In pfSense, go to Services > DNS Resolver and restart the service

I am having trouble running some attacks in the AD lab

1. Make sure your Kali VM is on the same subnet
   • Stop the VM
   • Go to VirtualBox settings for Kali VM
   • Change the network adapter to be on the AD_LAB LAN
   • Start Kali again
2. Make sure you have Windows Firewall completely disabled on the Windows 10 clients
   • Check the Tamper Protection setting
   • Ensure SMB is enabled on all parties
   • Google around on how the attacks work
   • Ask your peers

Creating a Windows 7 Buffer Overflow Practice VM in VirtualBox

In this module, we will look at creating a vulnerable Windows 7 VM in VirtualBox that will run some applications which are vulnerable to 32-bit stack-based buffer overflows
