Why Your Current Cloud Security Won't Prevent Attacks
Cloud environments are built on design failureโ€”and hackers are exploiting these failures every day. You can't monitor your way out of this problem. In Fugue's next Cloud Security Masterclass, Josh Stella (chief architect, Snyk) explores the taxonomy of cloud security involving the 3 vectors we can manipulate to design secure cloud environments: resources, actions, and time.

This week's articles


Not All SBOMs Are Created Equal
#explain, #supply-chain
A comprehensive SBOM is a valuable part of any organization's security toolbox. By looking at SCA tools critically and understanding their theory of operation we can generate more complete and accurate SBOMs.


Don't Panic: A Playbook for Handling Account Compromise with Sigstore
#ci/cd, #defend, #supply-chain
There's a myth that Sigstore makes revocation harder; in fact, the opposite is true! While it is true that the signatures on software are stored forever, software verification using Sigstore does support artifact revocation.


Introducing Package Analysis: Scanning open source packages for malicious behavior
#defend, #supply-chain
OpenSSF announced the initial prototype version of the Package Analysis project, a project addressing the challenge of identifying malicious packages in popular open source repositories.


Cloud-Native Ransomware - How attacks on availability leverage cloud services
#aws, #defend
Paper which outlines the paths a malicious actor might take to affect the availability of data by using the tools provided by Cloud Service Providers, as well as providing architectural patterns to make securing these systems easier and methods for detecting cloud-native ransomware.


CloudGoat goes Serverless: A walkthrough of Vulnerable Lambda Functions
#attack, #aws, #explain

AWS Icon  How to control access to AWS resources based on AWS account, OU, or organization ๐Ÿ”ฅ ๐Ÿ”ฅ
AWS IAM launched new condition keys to make it simpler to control access to your resources along your organizational boundaries. By using the new conditions, aws:ResourceOrgID, aws:ResourceOrgPaths, and aws:ResourceAccount, you can define access controls based on an AWS resource's organization, organizational unit (OU), or account. These conditions make it simpler to require that your principals (users and roles) can only access resources inside a specific boundary within your organization.
