OT/IT Security – Internal Firewall Fortigate Implementation with configurations for your critical networks
An internal firewall, also known as an internal network firewall or a segment firewall, is a security system designed to protect and control traffic between different segments within an organization’s internal network. Unlike a perimeter firewall, which protects the network from external threats, an internal firewall focuses on securing the internal network by regulating the […]
How to create DMZ (Demilitarized Zone) on Fortigate Firewall?
What is DMZ (Demilitarized Zone)? A DMZ (Demilitarized Zone) in computer networking refers to a physical or logical subnetwork that contains and exposes an organization’s external-facing services to an untrusted network, usually the internet. The purpose of a DMZ is to add an additional layer of security to an organization’s local area network (LAN); an […]
GRE Tunnels between multiple sites
A GRE (Generic Routing Encapsulation) tunnel in Cisco is a method of encapsulating and tunneling network traffic over an IP network. It allows the creation of a virtual point-to-point link between two endpoints, typically routers or switches, across an existing network infrastructure. Here’s how it works: GRE tunnels are often used for various purposes, such […]
Multiple company-sites IPSEC connection with multiple VLANs
IPsec, short for Internet Protocol Security, is a suite of protocols used to ensure secure communication over IP networks. It provides security services at the IP layer by enabling encryption, authentication, and integrity checking of IP packets. IPsec can be used to establish secure VPN (Virtual Private Network) connections between remote networks or individual devices, […]
Ethernet MAC Port-security
Today we will implement port security on our Cisco switch. We will bind the MAC address of the NIC device with our related port. So if some changes happen on the physical ports, then new device will be restricted. CISCO SWITCH MAIN CONFIGURATION Switch>enable Switch#configure terminal Enter configuration commands, one per line. End with CNTL/Z. […]
