I’m delighted to advise we officially unveiled yesterday our new Security solution: Cisco Hypershield. Cisco 👉 Hyper-distributed enforcement : IT infrastructure in a modern enterprise spans privately run data centers (private cloud), public cloud, bring-your-own devices (BYOD) and the Internet of Things (IoT).  In such a heterogeneous environment, centralized enforcement is inefficient as traffic must be shuttled to and from the enforcement point.  The shuttling creates networking and security design challenges.  The answer to this conundrum is the distribution of the enforcement point close to the workload. 👉 Hypershield was built on three key pillars: 🥇 AI-Native: Built and designed from the start to be autonomous and predictive, Hypershield manages itself once it earns trust, making a hyper-distributed approach at scale possible. 🥈 Cloud-Native: Hypershield is built on open source eBPF, the default mechanism for connecting and protecting cloud-native workloads in the hyperscale cloud. Cisco acquired the leading provider of eBPF for enterprises, Isovalent, earlier this month. 🏅 Hyper-Distributed: Cisco is completely reimagining how traditional network security works by embedding advanced security controls into servers and the network fabric itself. Hypershield spans all clouds and leverages hardware acceleration like Data Processing Units (DPU) to analyze and respond to anomalies in application and network behavior. It shifts security closer to the workloads that need protection.

Computer Networking is the practice of connecting computers together to enable communication and data exchange between them. In general, Computer Network is a collection of two or more computers. It helps users to communicate more easily. In this article, we are going to discuss the basics which everyone must know before going deep into Computer Networking. How Does a Computer Network Work? Basics building blocks of a Computer network are Nodes and Links. A Network Node can be illustrated as Equipment for Data Communication like a Modem, Router, etc., or Equipment of a Data Terminal like connecting two computers or more. Link in Computer Networks can be defined as wires or cables or free space of wireless networks. Types of Enterprise Computer Networks? LAN: A Local Area Network is a network that covers a small area, such as an office or a home. LANs are typically used to connect computers and other devices within a building or a campus. WAN: A Wide Area Network is a network that covers a large geographic area, such as a city, country, or even the entire world. WANs are used to connect LANs together and are typically used for long-distance communication. Cloud Networks: Cloud Networks can be visualized with a Wide Area Network as they can be hosted on public or private cloud service providers and cloud networks are available if there is a demand. Cloud Networks consist of Virtual Routers, Firewalls, etc. #snsinstitutions #snsdesignthinkers #designthinking

Navigating the Switch Landscape: Cisco vs. MikroTik" Introduction: The Duel of Titans In the vast realm of networking, two contenders vie for supremacy: Cisco and MikroTik. Each brings its unique strengths to the table, and organizations face the perennial question—should they go with the tried-and-true Cisco or venture into the MikroTik wilderness? Let's explore the facets that shape this decision. - 1. Price and Licensing: The Budget Battle - Cisco: The name resonates like a symphony, but it comes at a cost. Cisco switches are the thoroughbreds of the networking world, boasting quality, reliability, and a feature-rich pedigree. However, they're not exactly budget-friendly. - MikroTik: Picture a scrappy underdog—the MikroTik. Its RouterOS, with its free entry-level package, beckons to the frugal souls. For startups, small businesses, or those counting every penny, MikroTik's affordability is a siren song. --- 2. Packet Filtering: The Firewall Showdown - Cisco: The seasoned veteran. Its routers wield intermediate packet filtering capabilities. Think of it as a reliable bouncer at the network's entrance. - MikroTik: Here's where MikroTik flexes. RouterOS takes packet filtering to the next level. It's like having a Swiss Army knife for network security. If your network thrives on filtering finesse, MikroTik's got your back. --- 3. Switch Power Consumption: The Energy Tango - MikroTik: Brace yourself—the power bill is coming. MikroTik switches are notorious energy guzzlers. They party like it's 1999. If you're eco-conscious, this might raise an eyebrow. - Cisco: Cisco, on the other hand, sips its energy thoughtfully. Advanced tech wizardry keeps consumption in check. It's the Prius of switches. --- 4. Network Size and Uptime: The Grand Chessboard - Cisco: Behemoth networks, mission-critical services—Cisco thrives here. It's the seasoned general leading armies. Uptime? It's etched in stone tablets. The relation built over time doesn't hurt, as well as the political Made in the USA badge. Many Nigerian big businesses would rather older and even fairly used Cisco hardware than cutting edge from other stables. - MikroTik: Picture a cozy neighborhood café. Smaller networks, simpler troubleshooting. Uptime isn't life or death; it's more like a friendly handshake. MikroTik nods approvingly. Though of recent, much more powerful and efficient products from the Mikrotik stable are available to bring to a match against anything Cisco offers. --- Conclusion: The Verdict In the end, it's about aligning your stars. Cisco offers the Rolls-Royce experience—luxurious, dependable, and a tad pricey. Integration with popular infrastructure is also a plus. MikroTik? It's the Vespa—zippy, cost-effective, and maybe a little quirky. Choose wisely, young network traveler. Your destiny awaits. --- Disclaimer: The views expressed here are based on my thoughts and musings. Do consult their favorite oracle (or IT experts) before making decisions.

**My CloudBox Experiments in Networking** * I call the system I have at home CloudBox, where I connect various X86/64 and ARM (Raspberry Pi) devices together in a variety of network configurations to experiment. 1) Raspberry Pi, even the old versions (2 and 3) with 512MB RAM and running from an SD Card are GREAT to run and configure BIND9 DNS server on. This can be used to blacklist all advertisement servers, and any device on your network will no longer receive any ads - no Browser AdBlockers needed, and ads in mobile apps get blocked too. The configuration took me about a week to understand, the Pi DNS takes less than 5W to run. BTW, the same Pi can be used to host internal Linux repositories from a USB-attached SSD (less than 1TB). 2) Pi-hole is a sleek firmware on the Pi, very user-friendly. Though it sacrifices some deep customization compared to BIND9 on RaspiOS. I prefer BIND9. 3) OpenWrt is my favourite Router operating system/firmware. I always purchase Routers that can be flashed with OpenWrt. The UI is intuitive, and the controls are VERY detailed - Firewall control, converting your device to an AP, Router or Wireless Bridge, multiple LANs, VLANs (I am not great in this though), DHCP and DNS, running Network Time Protocol servers off of it. Just love it! Fun fact: TP-Link MR3020 is a portable router that fits in your palm, and can be run out of a powerbank, and it supports OpenWrt. 4) Mikrotik's RouterOS. Mikrotik is one heck of a hardware, and the RouterOS license comes free with the hardware (RouterOS is Mikrotik proprietory, not OSS). It is FAR better than OpenWrt in my personal opinion, but considering the price, I will pick OpenWrt any day. 5) Managed switches are great to learn VLANs (though I found it hard to wrap my head around). Getting switches (managed or unmanaged) that support Power-over-Ethernet is a better choice, as one can do away with lots of power cables for PoE cameras, and even some routers that can run off of PoE. I even have a sleek looking unmanaged 2.5GBE switch (though it is only for bragging rights, since not all my home networking is 2.5GBE capable. :P).

Types of Virtual Private Networks (VPN) There are two main types of VPN that people can use to securely connect to corporate networks. 1. Remote Access VPN A remote access VPN enables the user to connect their device to a network from outside their organization’s office. This device-to-network approach typically involves a user connecting their laptop, smartphone, or tablet to a network through their VPN. Increasingly, advances in VPN technology enable security checks to be carried out to ensure the device is secure before it is granted permission to connect. Remote access VPNs include cloud VPNs, which enable users to securely access applications and data via their web browser. 2. Site-to-Site VPN A site-to-site VPN enables connections between multiple networks. This network-to-network approach is typically used to connect multiple offices or branch locations to a central office. Site-to-site VPN encryption is useful for organizations with several offices based in various geographical locations. It enables them to share resources from a primary network, such as email servers or data storage facilities, across multiple locations. It also allows access to all users as if servers were located in the physical office.

Day 10: Computer Networking Computer network is a system that connects two or more computing devices, such as mobile phones or servers, allowing them to communicate and share resources. This connection is established through an interface, enabling seamless data exchange. Since all devices involved are computers or computing devices, this interconnection is referred to as computer networking. Hardware components -Nodes: these devices are connected to the network, like computers, smartphones, printers and servers. -Network Interface Cards: these are physical cards installed in devices that allow them to connect to the network and send/receive data. -Transmission cables: these are physical or wireless pathways through which data travels. example, ethernet cable, fiber cable. Networking devices: they are hardware units that handle dataflow and network management which includes; -Hubs: these are simple devices that help broadcast data to all connected nodes used in similar networks. -Switches: these forward data only to the intended recipient, improving network efficiency. -Routers: they direct data packets between different networks, enabling communication across larger span. -Firewalls: these are security devices that filter incoming and outgoing traffic to protect the network from unauthorized access. -Modems: they translate signals between digital data and analog formats for communication over telephones lines or cable lines. Software component Network operating systems: these are specialized operating systems designed to manage and control network resources such as user access, security and data flows. examples; window OS, Linux OS, MacOS. Types of computer networks. 1. Personal area network: this is a small network that connects devices like smartphones, laptop and wearables over a short distance. 2. Local area network: is a network that connects devices in a limited area such as home, office, or school. 3. Wireless local area network: this is a LAN that uses Wi-Fi to connect devices wirelessly. 4. Metropolitan area network: this is a network that spans a larger area than a LAN ,such as city or town. 5. Wide area network: this is a type of network that connect cities to cities, countries-countries. they connects your offices, cloud applications and cloud storage together. 6. Storage area network: It is used in large data centers where there is a need to store and access large amounts of data quickly and efficiently. 7. Virtual private network: It creates a secure tunnel over a public network, such as the internet. they are often used by businesses to allow employees to securely access company resources from remote locations.
