Basic techniques for working with the hardware and software of the "NETWORK SECURITY" stand

We are learning network security in practice! We are getting acquainted with the stand and its capabilities. 

Network security is a set of measures and technologies aimed at protecting computer networks and data from unauthorized access, use, disclosure, violation, modification or destruction. Our stand "Network Security" provides an excellent platform for students majoring in telecommunications at ALT Mukhamedzhan Tynyshpayev University JSC to study and practice the basic techniques of work in this field. In this post, we will talk about the key components of the stand and the basic principles of working with them. 

  1. Hardware part:Overview of the main devices: routers, switches, firewalls, servers, client machines, intrusion detection and prevention systems (IDS). Connecting and configuring devices: a step-by-step guide on connecting stand components to a single network, configuring IP addresses, subnet masks, and gateways.Hardware security features: learning how firewalls work, configuring them to filter traffic, and protecting against DoS/DDoS attacks.
