The Challenge of IP Reputation

When protecting clients and servers against network-based threats, it’s tempting to consider the peer’s network address when deciding whether that peer is trustworthy. Unfortunately, while IP addresses can be a valuable signal, attempts to treat traffic as trustworthy or untrustworthy based on IP address alone can be very prone to mistakes. Background Most clients andContinue reading “The Challenge of IP Reputation”

Defensive Techniques: Application Guard

Earlier this year, I mentioned that I load every phishing URL I’m sent to see what it does and whether it tries to use any interesting new techniques. While Edge’s “Enhanced Security Mode” reduces the risks of 0-day attacks against the browser itself, another great defense available for enterprise users is Microsoft Defender Application Guard.Continue reading “Defensive Techniques: Application Guard”

Kilimanjaro – To Exit Gate & Home

Saturday, July 8, 2023; Day 9 and Sunday, July 9, 2023; Home After another night of decent sleep, we turn on the light at 4:45am. It’s a cozy 50F in the tent. Our coffee should arrive in 15 minutes, and then breakfast will begin 15 minutes after that. Breakfast was quick — porridge and eggs,Continue reading “Kilimanjaro – To Exit Gate & Home”

Kilimanjaro – Descent to Mweka

Friday, July 7, 2023; Day 8 Last night’s sleep was the best to date, even with high winds and noisy groups traipsing by after 1am. Exhaustion is the best sleep aid, I suppose. :) The tent is again just under 40F, but I’m cozy in my wool hat. I slept from 7p-1a, 1a-3a, and 3a-5:30a.Continue reading “Kilimanjaro – Descent to Mweka”

Kilimanjaro – To Summit

Thursday, July 6, 2023; Day 7 It’s been noisy throughout the night as teams of hikers from Barafu pass through after midnight. They seem to make no effort toward keeping quiet, and there’s singing and shouts as they pass. Our 3am wakeup call arrives quickly, and most of us are up at 2:45am, eager toContinue reading “Kilimanjaro – To Summit”

Kilimanjaro –  To Kosovo/Respicius Camp

Wednesday, July 5, 2023; Day 6 I slept okay last night with long periods awake, turning a story over in my mind, the details of which I’ve since forgotten. At 5:50am I sat up when I heard the coffee crew preparing their hot water, and Jason broke the night’s silence with a joke: “You’re likeContinue reading “Kilimanjaro –  To Kosovo/Respicius Camp”

Kilimanjaro – Up Barranco Wall to Karanga Camp

Tuesday, July 4, 2023; Day 5 I slept okay last night, with no real nasal congestion unlike the night before, and the camp quieted down eventually. I had a few 1+ hour stretches of sleep. I jotted in my journal while enjoying my 5am coffee and wondering just how freezing my post-coffee bathroom trip willContinue reading “Kilimanjaro – Up Barranco Wall to Karanga Camp”

Kilimanjaro – To Lava Tower and Barranco Camp

Monday, July 3, 2023; Day 4 I didn’t feel quite as cold last night, and I got a solid amount of sleep. I had two mild-but-elaborate nightmares though, both featuring my ex. Ugh. I was a little congested, which is worrisome, but there’s so much dust in the air that blowing my nose leads toContinue reading “Kilimanjaro – To Lava Tower and Barranco Camp”

Kilimanjaro – To Shira 2 Camp

Sunday, July 2, 2023; Day 3 I slept somewhat more comfortably in the night — my sleeping pad, inflated by our porters before we got to Shira 1, was not overfilled and provided a bit more comfort than it had before. I also learned the trick of zipping my puffy coat down into a smallContinue reading “Kilimanjaro – To Shira 2 Camp”
