IAM Access Analyzer flags unintended access to S3 buckets shared through access points (AWS Security Blog, Apr 27 2020)
To help you identify buckets that can be accessed publicly or from other AWS accounts or organizations, AWS Identity and Access Management (IAM) Access Analyzer mathematically analyzes resource policies.

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.

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.
Thanks! – Lucas Samaras
