Core Networking Concepts: ACLs, VPN Security, and Cisco SD-Access

Access Control Lists (ACLs) and Configuration

An Access Control List (ACL) is a set of rules used on routers or firewalls to control network traffic and reduce network attacks. It filters traffic based on IP address, protocol, or port number.

Types of ACLs

  1. Standard ACL

    Filters traffic based only on the source IP address.

    • Range: 1–99 and 1300–1999 (expanded range).
    • Placement: Typically placed closer to the destination (since it does not check destination IP or ports).
  2. Extended ACL

    Filters traffic based

Internet of Things Fundamentals: Architecture, Protocols, and Lifecycle

IoT Device Lifecycle

The IoT device lifecycle comprises the sequential phases that an IoT device goes through, from deployment to decommissioning. The key phases are:

  1. Deploy: The device is physically installed and configured in its working environment.
  2. Monitor: The device’s status, performance, and data output are continuously observed to detect anomalies or failures.
  3. Service: Maintenance operations are performed, such as firmware updates, repairs, or calibration, to ensure optimal functioning.
  4. Manage:

IoT Access Technology Fundamentals

Communication Range Categories

IoT access technologies are categorized based on the distance they cover:

  • Short Range: Covers distances up to a few tens of meters. Examples include Bluetooth and Visible Light Communication (VLC), typically found in smaller IoT installations. These technologies often serve as alternatives to serial cables.
  • Medium Range: Extends from tens to hundreds of meters, with a maximum distance generally less than 1 mile. This is a primary category

Cloud Computing and Computer Networks Fundamentals

Cloud Computing Fundamentals

Cloud computing is a technology enabling users to access and store data, applications, and services over the Internet, rather than on a local computer or server. It provides on-demand computing resources such as servers, storage, databases, networking, and software.

Key Concepts of Cloud Computing

  • On-Demand Service: Resources like storage, processing power, and software are available whenever needed.
  • Internet-Based Access: All cloud services are accessed through the internet

SD-WAN, SD-Access, QoS: Core Network Technologies Explained

SD-WAN: Software-Defined Wide Area Networking

What is SD-WAN?

SD-WAN is a modern networking technology that enables organizations to manage and optimize their Wide Area Networks (WANs) using software-based controllers. It separates the network control function from the underlying hardware, allowing centralized and intelligent traffic routing over multiple types of connections such as MPLS, broadband, and 4G/5G.


Key Features of SD-WAN

  1. Centralized Control – A single dashboard to manage all WAN devices
