What is Networking?

Networking is all about the design, management, maintenance, operations, and troubleshooting of the network infrastructure, software applications, devices, and policies. Computer networking connects devices and endpoints via different types of computer networks.

 

What Are the 4 Types of Computer Network? 

Computer networks are categorized as per their size and the purpose served. These network types are:

LAN (Local Area Network) – A LAN is a group of computers connected to each other in a small area. LANs are used in offices, colleges, and institutes. This type of networking primarily uses a twisted pair or coaxial cable.

PAN (Personal Area Network) – A PAN typically exists within a range of 10 meters and is used for connecting devices for personal use.

MAN (Metropolitan Area Network) – A MAN is used to interconnect various LANs through telephone exchange lines. Due to its sheer size, it has a higher range than LAN.

WAN (Worldwide Area Network) – A WAN has a higher range and is used to connect multiple cities and even countries. WAN uses telephone lines, fiber optic cables, or satellite links.

 

What is Network Security?

In simple words, network security is a combination of techniques, technologies, and tools that work together to protect the network. It is the application of rules and policies for secure network configuration with the help of hardware and software technologies. The objective of network security is to defend the network from unauthorized access and ensure confidentiality, integrity, and availability.

 

Who Is a Network Engineer?

A network engineer or network architect is a technology professional responsible for implementing, functioning, maintaining, and fixing computer networks to ensure their connectivity and systems functionality within an organization.

How to select the best Network Security Program?

Selecting the best network security course is the first question that comes to mind while starting a career in this domain. Here are the criteria for selecting an ideal network security certification:

 

Vendor Neutral

The program’s objective should be to equip professionals with technologies in general, with no inclination towards any specific technologies. This would widen the scope for the candidate in terms of knowledge, jobs, and growth.

 

Course Content

An ideal network security training program should be designed to cover all the necessary topics that are relevant to the modern era of cybersecurity. The course should prepare students to protect, detect, respond, and predict network security incidents. This approach grooms the student to determine a possible hacking attempt in its initial phase and prepare for the threat accordingly. This training tactic is also helpful when it comes to determining multiple scenarios and outcomes.

 

Defense-in-depth Approach

Defense-in-depth is an approach to information security where multiple security controls are deployed in layers. If one layer fails, the other can cover to detect and protect from a cyberattack, ensuring sound security. Before a hacker penetrates the information system, it has to face all the security layers, which makes it close to impossible to get through.

 

 

Recognitions and Accreditations

The network security program should have some recognitions or accreditations from a governing body and mapped to job roles recommended by an internationally recognized body.
