On June 2, 2025, Sergeant of the Guard Sgt. 1st Class Andrew Jay took his final walk as a Tomb Guard at Arlington National Cemetery. In a powerful farewell, he laid roses at each crypt of the Unknown Soldiers, then walked off the plaza hand in hand with his 8-year-old son, Finn.

I drove by a restaurant today after a meeting that I haven’t seen in years. In 1998 the staff refused to serve me and laughed at me, after my jaw, pallet, and seven teeth were broken from a machine gun. Treat people with dignity and respect everyday… Thanks.

People were so much more happy at work today without masks. It’s also great to see smiling faces!

It seems that all/most of my personal accounts were targeted. Please be careful with comms.

Random: If someone could get YouTube to play videos at 3x (like Audible does with audiobooks), I’d really appreciate it. Thanks in advance!

Very sad to learn about the death of Alan Paller, a dear friend & mentor who cared deeply about making things more secure & bringing more young people into infosec w/ the right skills. Alan was great at making important things happen behind the scenes. sans.org/press/announcements…

#OnThisDay 100 years ago, the WWI Unknown Soldier was buried at the Tomb of the Unknown Soldier in ANC. A grand military procession transported him from the U.S. Capitol to ANC’s Memorial Amphitheater. There, he was honored with a state funeral before being buried in the Tomb.

Often asked if a red team should be comprised of insiders or outsiders. Just came across this CIA memo, "The 'Red Team'," Jan. 27, 1984, which presents the pros and cons perfectly.  bit.ly/3bOZ1hm

Earlier today, @1st_SF_Command held a wreath-laying ceremony at the gravesite of President John F. Kennedy to commemorate Kennedy’s contributions to the U.S. Army Special Forces, including authorizing the “Green Beret” as the official headgear for all U.S. Army Special Forces.

Totally agree with @RobertMLee. I studied public policy/economics/national security, with a minor in Russian Studies in college. Since cybersecurity problems are not purely technical, we need expertise from many fields in cybersecurity. – at Arlington, VA

Every now and then some level of gate keeping comes up in the cybersecurity community about how you have to be a programmer, or super technical, or whatever else is the flavor of the day to be successful. I was a Social Sciences - African Studies major in college. You’ll be fine.

Some interesting PhDs on cyber conflict / policy were written that never made it into books/articles etc. They may not have received the attention they deserve. Some of my favorites:

The S-Band Transponder was the main radio transmitter/receiver on the Apollo missions to the Moon, communicating 239,000 miles back to Earth. We've wired one up and transmitted successfully through it with a big stack of test equipment. 🧵
The S-Band Transponder with the cover removed. It is a box with complex wiring of thin coaxial cables, connected to modules with gold connectors. It has military-style round connectors on the top right, along with coaxial connectors.

The lab setup to test the S-Band Transponder. In the foreground, two conical antennas are pointed at each other. Three stacks of test equipment are piled up. At the far right is the Transponder. The components are connected with coaxial cables snaking over the desk.

One of the biggest challenges #infosec faces is that we have a disturbing number of charlatans in senior security roles at organisations. I had a call this evening which resonated with a disucssion yesterday and a mix of procrastination & annoyance has led to this 🧵...
