Introduction to Azure Virtual Desktop (AVD) Azure Virtual Desktop (AVD) is a desktop and application virtualization service from Microsoft that enables secure, scalable, and remote access to a Windows environment hosted in the Azure cloud. It helps businesses provide users with full desktop and application experiences, ensuring flexibility, security, and cost-efficiency in a modern, remote work environment.
What is Azure Virtual Desktop? Azure Virtual Desktop allows organizations to deploy Windows desktops and applications in the cloud, providing remote access to users from anywhere on almost any device.
Security Hardening: Security hardening is the process of configuring and implementing measures to reduce the vulnerability of a system, network, or application to potential attacks or breaches. This involves removing or disabling unnecessary features, patching known vulnerabilities, and configuring settings to minimize exposure to threats.
OS Hardening: The process of securing an operating system by reducing its attack surface, disabling unnecessary services and features, and configuring it to follow best practices for security.
Network Protocols
A set of rules for devices to communicate over a network, describing data delivery and structure. Serve as instructions for receiving devices to process data. Categories of Network Protocols
Communication Protocols: govern data exchange and transmission between devices. Management Protocols: monitor and manage network activity. Security Protocols: ensure secure data transmission using encryption. Communication Protocols
TCP (Transmission Control Protocol): establishes connections and streams data between devices. UDP (User Datagram Protocol): connectionless protocol for fast data transmission.
Understanding OCSP: Enhancing Digital Certificate Security The Online Certificate Status Protocol (OCSP) is a critical mechanism for maintaining the security of servers and network resources by checking the status of digital certificates in real-time. OCSP is an alternative to the older Certificate Revocation List (CRL) method, which required frequent updates to ensure client-side accuracy.
How OCSP Works OCSP addresses the main limitation of CRLs by providing real-time certificate status checks. When a user attempts to access a server, OCSP sends a request for the certificate status.
What is a Certificate Revocation List (CRL)? A Certificate Revocation List (CRL) is a critical security feature that maintains the trustworthiness of digital communications. Managed by a Certificate Authority (CA), a CRL is a directory of digital certificates that have been invalidated before their scheduled expiration dates. This list helps various endpoints, such as web browsers, determine whether a certificate should be trusted.
CRLs are essentially blocklists of certificates that should no longer be trusted.
Hub Switch Router & Modem Hub: A basic networking device that connects multiple Ethernet devices, making them act as a single network segment. It broadcasts data to all connected devices, which can lead to collisions and inefficiencies.
Switch: An advanced version of a hub that connects devices on a local area network (LAN). Unlike a hub, a switch intelligently forwards data only to the specific device that needs it, reducing collisions and improving network efficiency.

When troubleshooting network-related issues, capturing a network trace can be incredibly helpful. However, installing additional software or tools can sometimes be a barrier on production or completely locked down machines. Fortunately, there’s a built-in way to capture a network trace on Windows without installing any softwares locally.
Using the Built-in netsh Command
The netsh command is a powerful tool that allows you to configure and troubleshoot network settings on Windows. One of its lesser-known features is the ability to capture a network trace.
