Cloud native applications, based on the microservice architecture, interact with each other by sending requests or response through APIs. Arguably, API communications play an essential role in interactions of cloud native applications. Therefore, API security is an indispensable part of cloud native application security. API-related security issues shown below have...

INFRAHALT: NicheStack TCP/IP Stack High-Risk Vulnerabilities Threat Alert
Overview Recently, researchers from JFrog and Forescout released a joint report to publicly disclose 14 security vulnerabilities (collectively referred to as INFRA:HALT) in the NicheStack TCP/IP stack, announcing that these vulnerabilities could lead to remote code execution, denial of service, information disclosure, TCP spoofing, or DNS cache poisoning. Researchers noted...
Zero-Trust Cloud Native Network Security Enabled by Micro-segmentation
Traditional networks or virtual networks have employed network segregation technologies like VLAN or VPC which are, however, more often used for segregation of deterministic networks or tenant networks. In cloud native environments, containers or microservices have a shorter lifecycle and change more frequently compared with traditional networks or tenant networks....

Security Visibility Augmented by Cloud Native
In the cloud native era, containerized infrastructure makes possible much more lightweight applications that run faster. Dozens or even hundreds of containers can be rapidly deployed and run on a host. What's more, Kubernetes and other container orchestration platforms provide excellent security management mechanisms like load balancing, task scheduling, and...
