Top Four Risks When Using Serverless Function in Cloud Native Applications

September 10, 2021 | Jie Ji

Serverless is a new computing mode of the cloud native architecture, mainly taking the form of function as a service (FaaS). For the serverless mode, developers will write a function and define when and how to invoke it and then the function will run in the server provided by the cloud provider. All developers need […]

API Security in Cloud Native Applications

September 7, 2021 | Jie Ji

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 a direct impact on security […]

Zero-Trust Cloud Native Network Security Enabled by Micro-segmentation

August 31, 2021 | Jie Ji

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. Complex business access relationships are […]

Security Visibility Augmented by Cloud Native

August 25, 2021 | Jie Ji

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 fault tolerance. Therefore, in a […]

Windows Privilege Escalation Vulnerability (CVE-2021-36934) Threat Alert

August 24, 2021 | Jie Ji

Overview Recently, NSFOCUS CERT discovered a critical security bulletin released by Microsoft to disclose a privilege escalation vulnerability (CVE-2021-36934) in Windows. A privilege escalation vulnerability exists because of overly permissive Access Control Lists (ACLs) on multiple system files (including the Security Account Manager (SAM) database). When a built-in administrator account is enabled in the system, […]
