    Inquiring Minds Want to Know about Cyber Ranges

    Greg you are absolutely correct. Out to pasture describes me. At age 72, after 30 years of corporate training, I am doing an adjunct role for a local junior college and loving it. I get to grade students on their Packet Tracer Labs, easy peasy.

    Inquiring Minds Want to Know about Cyber Ranges

    Disclaimer, I am a grouchy old bastard. DoD Bases are all over the place, but having taught at many there is always someone responsible that you can push to make labs work. An airbase in Alabama had put us in a room with no service. The students had been provided with LTE dongles, but there...

    An A+ History question

    That first A+ M$ OS exam was the only certification exam (out of over 100 taken), I ever got a perfect score on, with no prep. Well, I was at IBM when the PC came out, and I did do PC/dos and MS/dos from the beginning. And I had multiple CNE's an ECNE and 2 MCSE's at that point. OK, it...

    CompTIA’s Role in Cybersecurity Careers

    Security+ is easy as I have seen the difference in hire rates due to DoD and Gov requirements. CySA+ and PenTest+ are good add-ons to Sec+ but more specific to particular job roles, and frequently overshadowed by OSCP and CISSP.
