🔴New whitepaper: Designing and deploying a data security strategy with Google Cloud
New 23 page whitepaper from the GCP team: “we wanted to explore both the question of starting a data security program in a cloud-native way, as well as adjusting your existing daily security program when you start utilizing cloud computing.” It covers the 3 pillars of effective cloud security (Identity, Boundary and Access, Visibility), controls that enable the pillars, rethinking your data security strategy, and more.

🔹How We Escaped Docker in Azure Functions
Vulnerability in Azure Functions which would allow an attacker to escalate privileges and escape the Azure Functions Docker container to the Docker host. Microsoft has determined that the vulnerability has no security impact on Function users as the Docker host itself is protected by a Hyper-V boundary.

The CSA Cloud Controls Matrix (CCM) V4: Raising the cloud security bar to the next level
The Cloud Security Alliance released version 4 of the Cloud Controls Matrix (CCM). The upgrade from CCM v3.0.1 to v4 has been imperative considering the evolution of the cloud security landscape, both from the technical and legal and regulatory standpoint. There was also a need for organizations to make the implementation of security and privacy controls more efficient and streamline compliance.

82% of companies unknowingly give 3rd parties access to all their cloud data
The Wiz team conducted a research of permissions provided to 3rd party vendors in cloud environments and the results should be a wake-up call. In the majority of cases these permissions are there for no reason: the vendor doesn't actually need them, and the customers aren't even aware that they gave them to the vendor.

🔹🔴Abusing cloud services to fly under the radar
NCC Group and Fox-IT have been tracking a threat group with a wide set of interests, from intellectual property (IP) from victims in the semiconductors industry through to data from the airline industry. In their intrusions they regularly abuse cloud services from Google and Microsoft to achieve their goals.

🔸Auditing PassRole: A Problematic Privilege Escalation Permission
iam:PassRole is an AWS permission that enables critical privilege escalation; many supposedly low-privilege identities tend to have it. The PassRole permission requirement is ubiquitous. It extends to more than 300 actions in more than 90 services and, in some cases, is obscured by parameters that indirectly contain the role being passed. Comprehensively auditing it can be a handful but is absolutely worth it as not doing so means leaving relatively easy avenues for privilege escalation wide open.

The Essential Guide to Cloud Security Posture Management
How CSPM automates security configuration across clouds
"Cloud Security Posture Management, or CSPM, is a relatively new cloud security
category designed to address configuration and compliance risks in your cloud infrastructure. The concept of CSPM is to enable organizations to automatically discover, assess, and remediate security configuration issues and gaps across multiple cloud providers and accounts. This approach ensures that at any given moment you have a consistent, secure, and compliant cloud infrastructure."

🔸AWS Lambda $LATEST is dangerous
You should always use function versioning. You should almost always use function aliases, which have a handful of benefits involving metrics in CloudWatch, IAM permissions, traffic-shifting, etc.
