Types of Networks
The networks come in different ranges from 2 devices to millions of devices connected on a single network. Some types of networks are as follows:
- Small Home Networks- It connects a few devices(1-10) connected to each other and the internet.
- Small Offices/Home Office Network(SOHO)- The small Office/Home Office or SOHO network enables computers within a home office or a remote office to connect to a corporate network or access centralized, shared resources.
- Medium to Large Networks- This type of networks are used by institution or organization or Schools with hundreds to thousand interconnected devices from many locations.
- World Wide Networks- It is the largest connected existing network in the world. It is a collection of private and non-private networks basically we called it Networks of Networks.
Networks and Process of Network Communications
If someone is interested or willing to join the world of Cyber Security he/she must be familiar with how Network Communication takes place. As the basic job of a cybersecurity analyst is to trace the event occur on the network. The record of the incident is stored in log files in systems involving in the network these log files contain the logs of network protocol operations. Through addresses, we can easily identify which hosts are connected to the organization or how many distant hosts are connected through the internet.
With the help of these addresses in log files, we can easily identify which of the hosts are connected or tried to connect, with hosts in organizations. Other addresses of protocols can provide information on what the network connection attempt to do and is this behavior is normal or suspicious or dangerous for connection. If any then analysts trace that threat for the security of the organization and their data. We must understand how the normal network works so that we can catch any abnormal behavior created by hackers or by any suspected software in the network. Network protocols work as a brain of the network and network services provide the task we want to perform using the network.
