More hardening configuration for extra security with FreeBSD 

 

Hardening configuration for extra security with FreeBSD

Thanks came in via Twitter so thanks to this person. This person highlights the default security holes that this BSD has. Maybe OpenBSD would be more appropriate since it was build with security in mind.

This lead to this comparison of OpenBSD being more secure from this 2014 URL

There is also HardenedBSD at https://hardenedbsd.org

How to Harden FreeBSD

FreeBSD over Linux

FreeBsd Vs OpenBsd

 

This is what spawned this analysis so  I can confirm deploying my trading stuff on FreeBSD

FreeBSD with C++ and Java stripped down for lowest latency potential HFT

FreeBSD with C++ and Java stripped down for lowest latency potential HFT

I think I would deploy on this environment with some basic compile library tools as hinted at this RenTech job posting among others postings

 

Rentech HFT tech job descriptions reveal quite a bit

More info

Rentech HFT says UNIX so lets look at open source FreeBSD

 

I will say this install was much easier than thought using FREE VirtualBox on a Virtual Machine

Note I chose the AMD 64 ISO for my Macbook with Intel I5

Install gcc for C++

pkg install lang/gcc

pkg install python27 python

openjdk includes the JRE and compiler

pkg install openjdk8

and openjdk8-jre

To secure and lock down the OS but this will be done at a much later time closer to production when ready to go

Rentech HFT says UNIX so lets look at open source FreeBSD

After studying jobs at RenTech, they want UNIX specific experience not Linux. So that got me thinking, what UNIX could they be referring to? If it was open source, there are really only 2 options of FreeBSD and OpenBSD. It seems FreeBSD is the more popular one:

Linux vs BSD, the difference? Free or OpenBSD? from BSD

Other options:

Join my FREE newsletter to see if I ever would implement with FreeBSD for high speed trading

The difference but generally Linux is bloatware if you are wanting stripped down performance for something like a high speed trading environment

Desktop option if you want

Install on VirtualBox
