How to Set Up OpenVPN on MikroTik: A Step-by-Step Guide to Secure Your Network

Image
  Step-by-Step Guide to Setting Up OpenVPN on MikroTik Router The best way of create server in Mikrotik router to connect Ovpn clients as below, Here we have described every step very easily and all CLI command clearly described. I have already discussed Ipsec VPN in my another Youtube video content you can also IPsec VPN configuration .   A.      Generate Certificates for secure connection of Ovpn clients. Creating certificates is crucial for establishing a secure and encrypted VPN connection. We'll generate certificates for the Certificate Authority (CA), server, and client. Create Certificate Templates :   Command : /certificate add name=ca-template common-name=myCA key-usage=key-cert-sign,crl-sign /certificate add name=server-template common-name=server /certificate add name=client-template common-name=client These commands create certificate templates for the CA, server, and client. The ca-template is used to sign o...

What is OSI Model: Layer Functions, Cyber Attacks, and Mitigation Strategies, buffer overflow attack.

  OSI Model Layers: Functions and Cyber Attacks.          What is OSI? The Open Systems Interconnection (OSI) model is a conceptual framework used to understand and implement standard protocols in networking. It divides network communication into seven distinct layers, each with its specific functions, components, and security concerns. Here's a detailed look at each layer: I have also added a detail video in the middle of the topic for your better understanding.  Physical Layer Function : Handles the physical connection between devices and the transmission of raw binary data over physical media such as cables and wireless signals. Components : Cables (Ethernet, fiber optics), hubs, repeaters. Basic Works in Networking : Transmission and reception of raw data bits, signal...

How to Set Up IKEv2 VPN with MikroTik Router: Secure, Reliable, and Mobile-Friendly Connections - A Step-by-Step Guide

  Step-by-Step configuration of IKEv2 VPN in Mikrotik Router.  What is IKEv2? Protocol Purpose : IKEv2 is primarily used to negotiate and establish IPsec security associations (SAs) for secure communication channels over the internet. It handles the authentication and key exchange process required to set up these secure channels. Security and Encryption : IKEv2 employs robust security mechanisms such as strong encryption algorithms (e.g., AES), integrity checks (e.g., HMAC-SHA), and secure key exchange protocols (e.g., Diffie-Hellman). These ensure that data transmitted over VPN connections is encrypted and protected from unauthorized access or tampering. Mobility Support : IKEv2 is known for its ability to maintain VPN connections even when devices switch between different networks (e.g., Wi-Fi to mobile data). It supports seamless mobility by quickly re-establishing connections without requiring manual intervention, making it suitable for mobile devices. Reliability : IKEv...

How to Backup MikroTik Routers: RIF vs. RSC - Understanding Their Benefits , Best Practices and differences

Backup MikroTik Routers: RIF vs. RSC - Understanding Their Benefits and Differences. In MikroTik RouterOS, backups can be made using two main types of files: RIF (RouterOS Information File) and RSC (RouterOS Script Configuration). The RIF file is often referred to as a binary backup, while RSC is a human-readable script export. These backups serve different purposes and have their own advantages and disadvantages. Here I have summaries of both files and the backup system.   RIF (RouterOS Information File) Purpose and Usefulness: Complete System Backup : RIF files provide a full binary backup of the router's configuration, including system settings, user credentials, and other sensitive information. Quick Restoration : These backups can be quickly restored to the same or an identical router, ensuring that the router is brought back to its exact previous state. Inaccessible Data : Since it's a binary file, it cannot be easily read or mo...
