For the time being, I expect this to be the final installment of my Security Essentials Series and true to the name, the following information is not terribly important, but is still very relevant – if you are in to this sort of thing that is. The following information covers some areas of cyber security that I have not previously addressed and includes some useless nerd skills you can practice on your own in the future.
External Hard Drive
This next bit is something that I almost never see included in other online security tutorials, which is why I am including it here today. If you want a fool proof way to secure, protect and back up all of your most important files, you should invest in what is known as an external hard drive. You can buy a USB external hard drive in any major box store for anywhere from $75 – $200 and it fully ensures that if you computer ever gets compromised, all of your files and data is backed up.
External hard drives are extremely important if you wind up getting a serious computer virus, such as ransomware. An external hard drive will allow you to completely wipe your computers data, clear the virus off your systems and then re-load your files right back onto your computer as if nothing ever happened. Considering that most ransomware will charge your thousands of dollars to un-encrypt your data, an external hard drive back up is literally a $100 fix to a $1,000 problem.
Contrary to popular belief, even if you are using a “Windows Computer,” you do not actually have to run Windows as your primary operating system. While learning how to use and install Linux is not necessary and often times a useless nerd skill, there is no debating that Linux systems are far more secure than Windows or Apple will ever be. Therefore, if you are truly interested in learning a new skill or improving your cyber security practices, then learning Linux systems should be at the top of your priority list.
I am not going to teach you how to do this in this article or any other for that matter, that is what they make Google and YouTube for. Instead, I will just tell you what the worlds most secure operating system is; TAILS.

Sweet cmd Commands
If your network connection ever starts to become slow or your web pages simply aren’t loading as fast as normal, there is a simple trick that will automatically speed your internet connection back up, without disconnecting you from the internet or requiring your internet router to be reset. The best part is, not only will the following command sequence speed your internet connection back up, but it can also negate DDoS attacks and will kick any 3rd parties, such as hacker, off your computer/connection every time it is used.
Simply go to start menu, open cmd and type in the following sequence exactly as it is written below – don’t actually type “(enter),” that is simply where you press enter before typing the next command:
- title H4x0r (press enter)
- color a (enter)
- echo off (enter)
- cls (enter)
- ipconfig/flushdns (enter)
- ipconfig/release (enter)
- ipconfig/renew (enter)
Please note that only the sequence in bold is necessary, the first part is just for fun 😛
