  Introduction: Looking to understand Citrix and its role in remote access and resource sharing? Dive in as we explore the world of Citrix, from virtualization to user connectivity. The Fundamentals of Citrix Citrix is a powerful provisioning tool enabling remote access and resource sharing. Learn how virtualization maximizes hardware efficiency, with products like Chanapp and Gen Desktop paving the way in the Citrix landscape. Evolution of Citrix Products With the release of version 7.x, Citrix introduced Virtual App and Virtual Desktop, reshaping the virtualization experience. Explore how Citrix Receiver, Gateway, Storefront, and Delivery Controller work together, alongside Active Directory and SQL Server for robust authentication and database management. End-User Connectivity Simplified Navigate the Citrix infrastructure with ease. Discover how the storefront server acts as a user-friendly portal accessed via a simple URL. Equip end users with the necessary tools like web browsers a

🎂 BGP: Time to Secure the 35 y.o. Core of the Internet

The recent release of the White House's "Roadmap to Enhancing Internet Routing Security" on September 3, 2024, addresses vulnerabilities in the Border Gateway Protocol (BGP), which was introduced in 1989 as part of the internet's development. ⚠️ Why is BGP security important? If not properly secured, BGP can be exploited to misroute, intercept, or disrupt internet traffic, leading to espionage, data theft, and service outages. BGP security ensures the reliability and safety of global internet infrastructure. ⏳ Did we have enough time to implement BGP security? Yes, but kind of... haven’t fully succeeded. While the basic hardening procedures for securing BGP are well understood, they have not been widely implemented. Protocols and tools like RPKI have been available for years, but many networks - particularly large ones - have been slow to adopt them. As a result, the current state of BGP security remains vulnerable. Proof of BGP insecurity can be seen in several major

A spectrum of possibilities and advancements with Network access authentication

  Security vs Convenience in Authentication Mechanisms Authentication mechanisms play a crucial role in network security, balancing the need for robust protection against the desire for user convenience. This balance is often a key consideration when implementing authentication protocols. Factors of Authentication Zero-ish Factors Open networks: Provide maximum convenience but minimal security MAC Authentication Bypass (MAB): Offers slightly improved security with minimal user interaction WPA2/3 Pre-Shared Key (PSK): Provides basic security with moderate convenience Single Factors Individual Pre-Shared Key (iPSK): Enhances security by assigning unique keys to each user 802.1X with Password: Implements username and password authentication for network access 802.1X with Certificate: Utilizes digital certificates for enhanced security Multi-Factor 802.1X Machine + User: Combines device and user authentication for increased security 802.1X + Multi-Factor Authentication (MFA): Adds an addit
