As promised from today (07.14) - A Story about Steganography

Some time ago, I was teaching a class on Security+ and we were having the Final Exam. We had two classes, day and night. The morning came and I slapped a piece of paper to the whiteboard that read:

Hey - so I posted the answer key on the server. But for security concerns, it will only be up there and available for the next hour. Please make sure you get it before the exam start.

I went back to my desk and sat down. Nothing further said. Just clickie-clickie on my computer as students' curiosities got the best of them. They came up and read the e-mail formatted note. They asked me about it. I said nothing. Then, I think they got the idea that they had to go looking on our local file server for it. So, in a scene that you could set to Yakety Sax, the students started scrambling around, looking on the server for a file that might be the answer key. They started searching through the student folders, opening various files and searching.

They couldn't find the file, but they did find one directory they couldn't access. The Day crew could not access the Night folder and vice versa.

Then one got the idea, "hey, what's the night student password". Day students logged on as night (passwords weren't particularly secure). So they got into the opposite class's folder, where they found a folder with a PDF and picture of the book cover. Upon trying to open the PDF and realizing it was locked down with a password, they scrambled trying to find it. It was then they looked at the pic:

"Dude, what was the name of that website that Rick used to hide stuff in images?"

So the students scrambled to find their notes on my discussion regarding steganography, which website I used in class (luckily, one of them wrote it down), and found the password to the PDF encoded in the book cover image. The classes had 60 minutes to recover the file, which turned out to be the exam key for the Final. Day got it in 58 minutes, night didn't get it.

But it was one of the better finals I've ever given - probably because they had something to gain by playing.

TL;dr - Used stego to hide a password to an encrypted PDF containing a final's answer key for an open book exam.

Do you have a similar story? Share below!

Cheers!

New Security+: closed beta?

So, we've all been hearing about the upcoming, new Sec+.

Me, I'm pretty excited about the new challenge, especially since I may end up teaching the class. Ssssoooo... are we sure there's no secret closed-beta people could try and get a seat on? ;) I had a blast with the PenTest+, CySA+ and Linux+ beta exams; those were fun!

@Stephen Schneiter has indicated that there's no beta, since the new version "is just an update". But hey, if The Professor says that 601 has 250 new topics compared to 501, that still sounds like a lot of changes that need testing.

From the CompTIA Research Vault: Understanding Total Cost of Ownership

As technology becomes more crucial to business operation, companies want to be sure they understand their IT budgets. CompTIA’s report on The Business Relevance of IT in the SMB Market found that the top three reasons for IT budget surprises are ongoing maintenance, required upgrades, and staff time required for operation. As technical candidates build skills using CompTIA A+ or CompTIA Network+, they should pay attention to how different topics tie together so that they can describe the total cost of building and maintaining systems.

Visually Impaired Accommodations During Exams

Hello everyone,

I have a student with a visually impaired disability who is trying to get help from PearsonVue for some accommodations. He requested accommodations through PearsonVue two weeks before his exam date, but never head back from them. During his exam using OnVUE, he had difficulty reading content on his screen, but was not able to use the magnifying glass feature to help see the images. He was also instructed to keep his face away from the screen by the online proctor so because his entire face was not visible when he moved very close to see the images.

Does anyone know what accommodations are available for visually impaired test takers? Or does anyone have any suggested strategies to better see the images on the screen during the exam using the OnVUE software?

Thanks.

Charging Instructors for Lab Access....really?

Wondering if anyone else has run into this issue when trying to create and run a course using the "new" CompTIA official hosted labs (really just the old rebranded Learn on Demand (LOD) labs).

I do not want to build out the lab environments locally and want to use a cloud provider; for a number of pragmatic reasons.

However; CompTIA and LOD have stated the following;

1. They make you (the instructor) PAY for lab access.
-- Charging instructors for access - when we are being an advocate for a vendor, one that brings paying students every term is simply misguided and wrongheaded.

2. Will only provide 30-day complimentary access to the labs
-- 30 days does no one any good.
-- Here is the real world… instructors need year-round access to content to build/revise courses.
-- AND.... after that, you have to pay.

Here is the real world as I see it - Instructors need year-round access to content to build/revise courses.
I like to use a certification vendor's "official resources" so I was happy when CompTIA stated they were "creating a new environment" but instead found that they simply rebranded the old LOD labs.

Due to this "policy", one is forced into to support other vendors; vendors that understand what instructors go thru ( and there are a lot of them).

It is just shocking that this is the official CompTIA stance, with the assumption being that its about money ( always about money). I assume they have to pay LOD for anyone's lab access, including the instructor...well if this is the case, perhaps someone at CompTIA should renegotiate this contract for those of us in the trenches providing a revenue stream.

Quality of CompTIA Learning Content

First a "thank you" to Stephen S. for providing access to CompTIA's learning content for the new CySA+ new exam (CS0-002). This access was granted to instructors participating in the ongoing Train-the-Trainer course relating to this certification. What I'm finding in going through this course is the high quality of content. That quality includes well-written learning lessons that are easy to navigate, and the periodic exercises that are designed to help determine if you are "getting it" in terms of understanding what's being taught.

In my new "retired" role (I retired from my full-time job with the California Community Colleges), I'm focused on updating my knowledge, skills, and abilities (KSAs), that relate to cybersecurity with hopes that it will improve the quality of my instruction. With CompTIA providing instructors with "free" access to these resources, I'd encourage all of us to take advantage of this opportunity.

Certmaster A+ Combo (Core 1 & 2) Instructor-led Training Presentation Planner

Hi CIN,

Has anyone of you tried delivering an A+ combo online instructor-led training (core 1 & 2) using the certmaster learn and labs platform in 10 days for just 3-4 hours a day?

Did you use a presentation planner as a timing-guide for the delivery? (similar to the one you get from logical choice).

Your inputs are greatly appreciated.

Thanks!

California Community Colleges (Contract Education) Seeking Instructors

As many of you know, I've been with the California Community College System for decades and will be retiring at the end of the month. Retirees have a 180 day period where they cannot work for our public schools (including colleges and universities). I've been asked to share the information and contact information with the group as there is a need for contract trainers. The information is below. This could be an opportunity for those interested in teaching. Me, well for the 180 days I think I'll take up getting addicted to eSports.

Contact information: Eldon Davidson - email [email protected]

His request:
I am working away on the CompTIA course offerings and establishing programs with the Army. My Dean, Jose Anaya, should be touching base with you soon and perhaps we can explore if there is a way for you to teach during your retirement waiting period. Until then, do you have an instructor or two that can teach the CompTIA courses at night and on the weekends?

A+ Instructor Training UK

Hi - Im very new to CompTIA and struggling a bit to get my head around requirements. Im hoping to deliver A+ as part of a qualification for college students in September. Do I need to be qualified as a CompTIA instructor to do this? Is the Cisco IT Essentials one way of delivering the course prior to the 1001 and 1002 exams? If I do need training (Cisco Instructor for IT Essentials) how do I find out who is running a course - I have gone around in circles talking to Cisco themselves, they just keep sending me links to ITC that dont have any relevant courses. Any help would be really appreciated.

Offering CEU credits for our courses. How to do it?

Hello everyone,

We have an associated technical school that offers a lot of training in networking and security. How would we be able to ensure our students are able to get CEU credits for those classes? I'm assuming there's some sort of review process that we would have to work through. If anyone knows who we should talk to I would love to know.

Thanks!

Creating Engaging Online Classes

Getting used to learning online can be daunting for both instructors and students. Zeshan Sattar, CompTIA director for learning skills and certifications, shared some words of advice around how to make online classes engaging, and suggestions for students to resist distractions. Zeshan participated in a LinkedIn Live session with CompTIA's Kelly Stone.
