I was one of the early RHCE (Red Hat Certified Engineer (IIRC)) around 15 years ago.
I let the certification expire - I couldn’t find anyone to hire me to do that, even working at a consulting firm at the time.
If the situation has changed that radically, I guess it might be worth dusting the corners of my brain.
A lot of companies are opting for CentOS. They keep a few mission critical’s on RHEL but by and large CentOS is re-shaping the landscape.
The nice thing about CentOS, though, is that the RHCE knowledge is applicable to that platform as well.
Relative to other systems, how secure is Linux?
Security is a process--not an event or an application, or an OS. Security is a full-time process that one must use to keep the network from being breached in any way.
That being said, Linux is fairly easy to set up for the various policies required to be secure. It is even possible to lock out the administrator (root, in Linux) to the point of it being a useless account. There are enough tools for Linux to make the system and network quite secure--moreso than Windows, IMHO.
I’m seeing more and more use of linux in server rooms, but not on desktops.
Well, since I am now teaching IT courses and we pay close attention to national job trends; I must have missed this overwhelming demand for Linux gurus. A background in multiple OS is going to obviously going to be helpful as is knowledge of multiple programming languages and multiple database systems. Most job listings are ridiculously specific with regard to experience and knowledge base. If you are a networking person then certainly, a good knowledge of Linux as well as Windows Servers is essential.
Thanks.
Would aluminum foil be useful in any way to increase security in one’s computer work space?
For later
Very true. Even knowing Linux without a certification will get you an interview at many places, and or can even seal the deal if it comes down to them choosing between equally qualified people, one knowing some Linux and the other not.
I worked at a place that had a couple of wiring closets that actually looked very similar to that! Was a total nightmare to simply install or replace a switch.
Linux is playing a big role in server virtualization. We are looking a linux person to help administer our VMware infrastructure.
It has been a while but wasn’t CentOS a rather middling desktop distro at one time? I didn’t even know they did servers and stuff, probably because I’m not into that.
That is true because CENTOS is basically Red Hat with the trade mark information removed, no red-hatted Shadow Man logo and no Red Hat technical support.
Wow, you’re one of the few. Actual RHCEs in the wild are hard to find these days. We’re a HEAVY RHEL shop with Windows as our backbone. I’ve made my gravy off of Microsoft for 20 years, but I’m an advanced Linux user; and I can tell you that my knowledge of Linux was part of the reason my boss hired me. If you can bat from both sides, you’re a force to be reckoned with.
