Editorial take
The most useful five minutes in security audio for anyone who defends a network. Johannes Ullrich, dean of research at the SANS Technology Institute, reads through the Internet Storm Center's handler diaries and the day's patches, exploited zero-days, and scan trends, with almost no filler. What sets it apart from other daily briefs is the data: stories often start from what the ISC sensors and honeypots actually logged, not from a press release. Friday episodes regularly add a short interview with a SANS.edu graduate student about their research paper. The limitation is depth: five minutes can name a CVE and say patch it, not teach you why it works. Treat it as a morning checklist, then go read the linked diary.

Listen if you …
- work in a SOC or run infrastructure and need to know what to patch today
- want sensor and honeypot data rather than vendor marketing in your news
- have five minutes, not fifty, and want them used well
Skip if you …
- you are new to security, it assumes you know what a CVE, a honeypot, or an SD-WAN manager is
- you want analysis or opinion, this is a fast technical brief
