This report is a follow up to https://www.horizon3.ai/vmware-vrealize-log-insight-vmsa-2023-0001-technical-deep-dive/. Earlier this year we reported the technical details for VMSA-2023-0001 affecting VMware Aria Operations for Logs (formerly VMware vRealize Log Insight). In that report, we showed how an attacker could use three different CVEs to achieve remote code execution. During the course of that investigation, we noticed … Read more
The Open Systems Interconnection (OSI) model is a conceptual framework that provides an organized approach to how network communications happen between devices. The model divides communication into seven layers, each responsible for different aspects of the communication process. This article will take a deep dive into the OSI layers, explaining what they are, how they … Read more
When it comes to networking, there are a lot of layers and technologies that work together to create a seamless experience for users. Two of the most important layers are Layer 1 and Layer 2. These layers are responsible for laying the foundation for communication between devices on a network. In this article, we’ll take … Read more
EIGRP and OSPF are two popular routing protocols used in contemporary networking. They both serve the purpose of directing traffic and determining the optimal path of data from one network to another. But what are the technical differences between them? How do they compare in terms of features, scalability, and stability? In this article, we’ll … Read more
As a network engineer, understanding the OSI model is essential for designing, implementing and troubleshooting network infrastructure. The OSI model is a conceptual framework that describes how data moves between devices and applications on a network. It is organized into seven layers, each with its own specific function. In this article, we’ll take a deeper … Read more
As our reliance on digital communication continues to grow, understanding the various layers of networking becomes increasingly important. Two particular layers – Layer 2 and Layer 3 – are particularly essential when it comes to ensuring efficient data transmission and the success of network operations. Here is a deep dive into these two networking layers. … Read more
The OSI (Open Systems Interconnection) model is a conceptual framework that was developed by the International Organization for Standardization (ISO). It was designed to facilitate communication between various computer systems by dividing the process into seven distinct layers, each of which has a specific function. In this article, we will take a deep dive into … Read more
The TCP/IP protocol suite is the backbone of the internet. It consists of a suite of protocols that work together to enable communication across the internet. In this article, we’ll take a deep dive into some of the most important protocols and services in the TCP/IP suite, including IP, DNS, and HTTP. IP (Internet Protocol): … Read more
As the internet continues to evolve and transform the way we communicate, conduct business, and access information, the TCP/IP protocol remains a fundamental building block of its architecture. The Transmission Control Protocol/Internet Protocol (TCP/IP) is an open system of protocols that enables communication between devices over a network, regardless of the hardware or software used. … Read more
