@runforserenity One of the great things about Amazon -- I get some stuff the same day I ordered it 😃

I’ll be at EDUCAUSE CPPC next week speaking about Zero Trust on Thursday, come by and say hello #CybersecPrivacy22

@randymarchany Good thing we never had them 😀

@randymarchany The question is: Are you working from home, or living at work. If you don’t separate your work space from your living space, your at home office construct is broken.

Confirmed: The DNS records that tell systems how to find https://t.co/qHzVq2Mr4E or https://t.co/JoIPxXI9GI got withdrawn this morning from the global routing tables. Can you imagine working at FB right now, when your email no longer works & all your internal FB-based tools fail?

May I please get 2 followers to copy and re-post this tweet? I'm trying to demonstrate that someone is always listening.

Just two. Any two. Copy, not retweet.

Scammers will try almost anything to get inside a company & launch ransomware. Apparently now that includes emailing employees directly & asking them to unleash ransomware inside their employer’s network in exchange for a percentage of any ransom paid. https://t.co/3VOcAuEHrU

Please stop for a moment and watch this, with the sound on. Share with others. An unflinching rebuttal to all those who are politicizing studies of race and injustice courtesy of Mark Milley, the chairman of the Joint Chiefs of Staff.

@Astro_Mike Just finished your book. Thank you for writing it!

I subscribe to this great website called Bookbub. I told them my interest was SyFy and I get a suggestion every day - problem is a lot are for some post apocalyptic story. I don’t see the point in reading those as I get them for free from the news.

@vmvogel @VantageTCG Congratulations Valerie, it’s good to see that your extensive education experience will be put to good use. I know that anyone you consult for will be lucky to have you!!

@randymarchany Most corporate networks would not last in our open environment. I tell pen testers calling me that we run 24/7 pen testing.

UPDATE: INDOOR DINING WILL NO LONGER RESUME ON THURSDAY.

We had planned to loosen restrictions this week. However, after #COVID19 spikes in other states driven by, in part, the return of indoor dining, we have decided to postpone indoor dining indefinitely.

What does a mask do? Blocks respiratory droplets coming from your mouth and throat.

Two simple demos:

First, I sneezed, sang, talked & coughed toward an agar culture plate with or without a mask. Bacteria colonies show where droplets landed. A mask blocks virtually all of them.

About real risk vs fancy 0-days.

Probability of getting compromised via:

phishing > 0-day

Insecure RDP > 0-day

(long time) unpatched / out of support software > 0-day

password reuse attacks > 0-day

etc...

Care about the basics first.
