Embracing Secure Remote Work: Exploring the Synergy of VDI, VPN, RBI, and Zero Trust Technologies

In this Gist, I've shared two tables that outline the steps and technologies involved in creating a secure remote work environment using VDI, VPN, RBI, and other security measures. The first table is a 6-step user journey highlighting risks and mitigation strategies. The second table presents additional steps and technologies to create a Zero Trust remote work environment.

VDI (Virtual Desktop Infrastructure): VDI is a virtualization technology that allows users to access a fully functional desktop environment remotely. It creates virtual machines on a centralized server, each running a separate operating system instance. Users can access these virtual desktops from their devices using a remote desktop protocol. VDI helps enhance security by keeping sensitive data within the data center, simplifying patch management, and providing centralized control over user access.

RBI (Remote Browser Isolation):

Installing Home Assistant on OrangePi 5 Board

This tutorial will enable the use of Home Assistant on an OrangePi 5 board with the following characteristics:

OrangePi Debian OS
OS running on a SDCard
Home Assistant Supervised Instalation

The steps are a compilation with few modifications from instructions found over the web. Links are at the end.

Step 1

Go to your work folder, mine is located at: F:/Work/EnterpriseName/

And then create a .gitconfig-work with the following data:

	//bookmarklet-title: Canvas DL
	//bookmarklet-about: When playing skribbl.io and someone has made a nice drawing, this lets you download the current drawing as a PNG.

	var w = window.wdq \|\| (window.wdq = document.createElement("a"));
	var p = /The word was '([^']*)'/g,
	pp = /<span>([^<>]+) is drawing now!/g,
	tt = document.body.innerHTML;
	var mm, nn, xx;
	while (mm = p.exec(tt)) nn = mm;
	while (mm = pp.exec(tt)) xx = mm;

	import resource
	from functools import wraps


	def mem_it(func):
	@wraps(func)
	def wrapper(args, *kwargs):
	pre = resource.getrusage(resource.RUSAGE_SELF).ru_maxrss / 1024
	print(f'Pre-memory usage: {pre} (mb)')
	f = func(args, *kwargs)
