Filter Out the Noise
Since I started this curated newsletter in June 2017, I’ve clipped ~14,000 articles and narrowed them down into the best 20 per day & best 15 per week. This is my favorite way to cut through all the security marketing and hype. If you’re enjoying it, tell a friend. If you hate it, tell an enemy.

9. Improving your security posture with centralized secrets management (Google Cloud Blog, Apr 28 2020)
One of the biggest advantages of a centralized secrets management solution is mitigating secret sprawl. Without a centralized solution, secrets–like API keys, certificates, and database passwords–often end up committed to a source repository, saved on a corporate wiki page, or even written on a piece of paper. When secrets are sprawled like this, you lose the ability to easily audit and control access to their values, allowing an attacker to move undetected throughout a system, as has happened in several recent data breaches.
