homelab for grownup

I have just completed re-building my home lab and it took for few weeks to make certain worked. Hypervisors and pfsense are core parts of systems, but I also want to try that legacy or retired gadgets like Cisco ASA or HP DL3 series. Using cloud services such as AWS, Azure or DigitalOcean could make our life more easier, but on-premise systems are still important to understand what is going on there.

I feel like installing the Pfsense is at least 5 times easier than Cisco ASA. We can make connection worked even few mouse clicks; however, we can not understand how packet flows and how to make different machines are connected between each other under hood. There’re lots of trial errors as always. From wipe-out firmware images on that bare-metal firewall to complete ACL, those process gave me lots of fun anyway.

Each networks are divided into different VLANs and totally isolated each other to prevent security holes. Maybe I could do malware analysis on this environment. Metasploitable 2 and DVWA/WebGoat will be used for penetration practice, then any packets between attack/target machines are monitored.

Regarding the hyper visors, I would like to say, they have both pros and cons. Windows Hyper-V provides ease-of-use experience with nice looking graphic interface. More than that, we can use Hyper-V bare-metal machine as a monitoring server as well. But it requires lots of computing resources. ESXi is a very solid hyper visor and it needs few resource. Although I reinstalled because of its’ speed, it was working okay on 32GB SD Card. I am still not so sure which one is better, so I am using two hyper visors simultaneously.

My total budget for this lab was under 400$ CAD thanks for the retired but still healthy generals.

Preparing Forensic USB

USB (Ext4)

Created Ext4 partition for USB Drive using AOMEI application.

Install package/software

Linux Memory Grabber, Linux Memory Extractor and Volatility Framework are mostly used for memory forensic analysis. Those will be installed on USB drive then attached to SIFT-Workstation.

Git Repository;
Linux Memory Grabber: https://github.com/halpomeranz/lmg.git
Linux Memory Extractor: https://github.com/504ensicsLabs/LiME.git
Volatility Framework: https://github.com/volatilityfoundation/volatility.git

Move to USB Drive folder, then;
$git clone https://github.com/halpomeranz/lmg.git .
$git clone https://github.com/504ensicsLabs/LiME.git lime
$cd lime/src
$patch < ../../lime-Makefile.patch
$cd -
$tar xf static-dwarfdump.tgz
$git clone https://github.com/volatilityfoundation/volatility.git

CAPTURING LINUX RAM

Attach USB on SIFT VM and start capturing Linux RAM

$sudo ./lim
