DESIGNING FOR SECURITY AND USABILITY: FIGMA'S MODERN ENDPOINT STRATEGY

Figma's security team developed an endpoint security strategy that emphasizes device quarantine, allowlisting, and access controls for improved usability and security. They implemented the Endpoint Security Baseline (ESB) using OSQuery to identify security risks, placing devices in quarantine if threats are detected until they can be resolved. Figma also deployed Santa for application allowlisting and Opal for just-in-time access to SaaS applications.

AUTOMATING AWS PRIVATE CA AUDIT REPORTS AND CERTIFICATE EXPIRATION ALERTS

AWS Private CA is a service that allows an organization to issue certificates via ACM without the need for a public certificate, which may disclose sensitive services. However, certificates generated via the console default to a 13-month validity period. In contrast, certificates generated using the SDK or CLI are more flexible, but they do not include certificate expiration notices. The solution in this post leverages Lambda functions to periodically generate a report of certificates and notify via email and Security Hub of any certificates that are expiring within 30 days.

EVERYTHING TO KNOW ABOUT RUNTIME REACHABILITY

Runtime reachability enables security teams to prioritize vulnerabilities that require immediate attention. It includes network reachability, package-loaded reachability, and function execution reachability. Package-loaded reachability may prioritize false positives, while network reachability might de-prioritize vulnerabilities in non-internet-accessible systems. Function execution reachability is the most robust but requires a (C)ADR.

VERIZON DISCOVERS SPIKE IN RANSOMWARE AND EXPLOITED VULNERABILITIES

According to Verizon's 2025 Data Breach Incident Report, the company observed a 47% increase in the rate of ransomware detected in data breaches. Verizon has observed a decrease in the average payout and the percentage of organizations that paid ransoms, but also noted that small-to-medium-sized businesses were particularly hard hit. It also stated that exploited vulnerabilities, serving as an initial access vector for breaches, surged over the past year, primarily due to attackers exploiting zero-day exploits in edge devices and VPNs.
