IT Infrastructure & Security - Summer 2018


(8/10) Final Grades are posted. Sorry to be so long with excellent results, those who participated showed me the best I get to see. My vision's back OK, needs to be rationed, was well-spent looking over this stuff!

(7/12) The progress report for Summer '18 at info300.net appears to be ready for the summer. Three Files that meet specs and your Outlines/Brief1 with an approved topic are due Tuesday the 17th. The outline and references are due Tuesday the 24th. The printed brief is due at the exam time, webwork to specs by the end of the next day...

(7/11) The server at info300.net is up and reporting progress toward the HOL project and tech market brief. Userids and passwords were given to a very small class this evening. The first tasks are to learn vi/vim and key in and otherwise demo skills in vi. Do not use Windows or Mac editors and copy stuff to/from the server. Key in some prose, poetry, or whatever gets some experience editing files with vi. Learn how to copy/paste, search/replace, Vi/vim is an operating system component for all versions of unix and skills with it at the command line are entry-level for jobs in networking and security.

I've been showing people how to work at the command line and use vi since 1981 and have never recommended anybody who can't or won't do it for anything. Skills with unix at the command line and a portfolio with exhibits for security and admin can make $30K or more difference in starting salary!

(6/25) Dates: No class 7/4 for Independence Day. Quiz #1 is set for 7/9. The LAN project is due 7/16.

(6/18) The MSDNAA-MicroSoft Developer's Network Academic Alliance appears to be ready for us, although it's planned to be down for maintenance Tuesday the morning of 17th. The url is go.vcu.edu/bussoft and it appears to use VCU CAS. Important ISY Information has some details. Get Visio 2016 Pro, and if you're getting Visual Studio get the full product, not the Community version or you'll be missing proprietary stuff needed for INFO350 and INFO465. If you need help virtualizing a Mac the net techs should be in their office from 12-5PM M-Th (subject to changes occasionally). Schedule ahead of time at isysupport@vcu.edu or call 804 828-7129, or the dept office at 828-1737 if you need help tracking them down.

F I N A L Grades from last semester are posted. This summer's will be similarly assigned, hopefully more Aces.

Ask about extra credit for putting up your info300.net site on your own domain and virtual (or real) server. Get a domain, set up a linux server, firewall it, and host your info300 web pages there. Don't just put up a page at some hosting site. It should be a virtual server, like Digital Ocean or RackSpace, where you are root, own the domain, and are working at the linux command line. That's worth 5 bonus points. Getting an ssl certificate and making it able to get mail to my inbox at @vcu.edu with no warnings is worth another 5 points.

I'll do some of it in class, following the steps in the Networking topic, a ways down the page, Setup and Secure a Centos 7 LAMP Stack at RackSpace. There are lots of on-line resources for setting up a virtual server, and it's a good start into a career in network management and security.

Let me know ahead of time if you're working at these 5 or 10 points. You'll be working at your own risk with little support. Students can snarl stuff up so tight it defies untangling and the instructor can't always debug a setup, but will look into it a time or two... One student recently incurred $650 in bandwidth charges from RackSpace when his account was compromised, maybe into a DDoS attack!

Prior notes from the Spring were been moved to Prior Notes, as will the summer's notes when they're aged...

First Three Topics:

(6/11) Info Tech Infrastructure, in recent tradition, is in three major technologies: Computers, Networks, and Storage. The course starts with these major topics. For a few decades, we've seen these as separate boxes built by companies like IBM, Cisco, or Seagate. After 2015 or so, we've seen these technologies virtualized and hyperconverged a few ways, including an ARM64 SOC released in 2017 that does it all...
