  I abandoned this post back in March h202 because I was unable to get keycloak to contact samducker. I’m publishing it now mostly because of SamDrucker. keycloak is a vnet jail. Interesting things happen there. From time to time, security issues are found within software.

• University of Toronto ☛ Thoughts on having SSH allow password authentication from the Internet

  On the Fediverse, I recently saw a poll about whether people left SSH generally accessible on its normal port or if they moved it; one of the replies was that the person left SSH on the normal port but disallowed password based authentication and only allowed public key authentication. This almost led to me posting a hot take, but then I decided that things were a bit more nuanced than my first reaction.

• Andrew Stiefel ☛ Markdown Files, Not Apps

  Files, not apps. I’m convinced this is the best way to work in the future.

  I write down almost everything important in my life: lists, ideas, plans, code, and articles. They form my extended memory. They are a record of what I’ve done, and who I’ve been. That’s why I only use markdown files.

  Traditional document and note-taking apps like Word, Evernote, and Notion create data silos and vendor lock-in, limiting your ability to freely move and process information.

  I discovered this the hard way when I tried to move between different ecosystems like Evernote and Apple Notes. Sure, there was a way to export my data. But it was a mess. Things broke, attachments went missing, and I spent hours converting, reformatting, and importing.

• SANS ☛ Leveraging Honeypot Data for Offensive Security Operations [Guest Diary]

  As your team identifies scanners and their associated IP addresses, this information can be stored in a private repository and leveraged as part of build scripts for your red team infrastructure.
