stp2y0 CommentsNewsbasic, coding, community, development, devops, engineering, inclusive, learning, networking, software

In networking, efficient and fair use of shared communication channels is critical to minimizing data collisions and maximizing network performance. Two foundational protocols that manage network access in this context are Carrier Sense Multiple Access with Collision Detection (CSMA/CD) and Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA). These protocols are essential to network performance, particularly in Ethernet (for CSMA/CD) and wireless (for CSMA/CA) environments. Let’s dive into the details of how each protocol works, where it’s used, and its significance in network management. What is CSMA? Carrier Sense Multiple Access (CSMA) is the overarching method that allows devices on…

BUILDING A CYBERSECURITY DETECTION AND MONITORING LAB BY LEVERAGING LOCAL VIRTUAL MACHINES (VMs) AND MICROSOFT AZURE

stp2y0 CommentsNewscoding, community, cybersecurity, development, engineering, homelab, inclusive, networking, security, software

Introduction Learning and implementing cybersecurity concepts can be challenging without access to practical and secure infrastructure. These challenges are further complicated by budget constraints that limit the acquisition of necessary hardware resources. To overcome this, this home lab guide provides instructions for provisioning, configuring, optimizing, and securing IT infrastructure using a combination of local virtual machines (VMs) and cloud resources for practical use cases. This approach enables deploying less resource-intensive tools on local VMs while leveraging the cloud for more demanding applications. It simulates both on-premises and cloud environments. The knowledge gained here can aid in production and large-scale, enterprise-level…

This article was originally published on the Metered Blog: WebRTC WHIP & WHEP Tutorial: Build a live Streaming App WHIP (WebRTC-HTTP Ingestion Protocol) and WHEP (WebRTC-HTTP Egress Protocol) are protocols that are designed to streamline signalling in WebRTC with the help of standard HTTP methods Definition of WHIP: WHIP simplifies how client devices send media streams to the server. It replaces the complex signalling mechanism that is required with simple HTTP GET requests, thus making it easier to ingest media into servers Definition of WHEP: WHEP protocol is used for delivering media streams from servers to clients. It uses the…

Rasp-Pi Network ID tool

stp2y0 CommentsNewscoding, community, development, engineering, inclusive, networking, pfsense, raspberrypi, software, waveshare

I needed a tool that could display relevant network information as quick as possible. Armed with a Raspberry Pi 3 B+, 2.13 inch Waveshare e-paper HAT V2, and a curiosity to explore its potential, I set out to develop a tool that could display network data. This was born out of necessity while I was setting up VLANs within PfSense. I got tired of using "ipconfig /release" and "ipconfig /renew" while testing network segregation and firewall rules. I will share that project in an additional post. I plan making this post as concise as possible. During my research to make…

Why data needs to be secure and encrypted? A lot of critical informations such as Credit card details, your net banking credentials, confidential documents are continuously transmitted over the internet and keeping these data encrypted is crucial for the Internet to work the way it works today. You wouldn't want to propose to your crush over internet if you knew that everybody can see your messages right? Types of Encryptions Widely there are two ways to implement encryptions. Symmetric key Encryption: Symmetric-key algorithms are algorithms for cryptography that use the same cryptographic keys for both the encryption of plaintext and…
