What is CYBERSECURITY?

 What is CYBERSECURITY?


CYBER : is relating to or involving computers or computer networks.


SECURITY :  is protection from, or resilience against, potential harm caused by others, by restraining the freedom of others to act.


CYBERSECURITY : Cybersecurity or information technology security (IT security) is the protection of computer systems and networks from attack by malicious actors that may result in unauthorized information disclosure, theft of, or damage to hardware, software, or data, as well as from the disruption or misdirection of the services they provide.


Cybersecurity is one of the most significant challenges of the contemporary world, due to the complexity of information systems.


The field has become of significance due to the expanded reliance on computer systems, the Internet, and wireless network standards such as Bluetooth and Wi-Fi, and due to the growth of smart devices, including smartphones, televisions, and the various devices that constitute the Internet of things (IoT).


How does CYBERSECURITY work?


Cybersecurity works on protecting the data against unauthorized modification, unauthorized deletion, unauthorized access. The three main principles that acts as the security pillar for organisations are confidentiality, integrity, data availability also known as CID/CIA triad.


Confidentiality is  that, information is not made available or disclosed to unauthorized individuals, entities, or processes.

Data Integrity  means maintaining and assuring the accuracy and completeness of data over its entire lifecycle. This means that data cannot be modified in an unauthorized or undetected manner.

Availability means the information must be available when it is needed. This means the computing systems have to store and process the information, the security controls  to protect it, and the communication channels to access it, must be functioning correctly. This involves properly maintaining hardware and technical infrastructure.


Why CYBERSECURITY needed?


Cybercrime is an increasingly serious problem, and to address it, strong CYBERSECURTY is needed. Individuals, governments, for-profit companies, not-for-profit organizations, and educational institutions are all at risk of cyberattacks and data breaches. To minimize the risk of an attack and to secure systems and data, strong cybersecurity  will play vital role.

WHAT IS HTTP ?? HOW HTTP WORKS?

What is HTTP? HTTP is a protocol. HTTP stands for Hypertext standard protocol . It is defined as a set of rules used for communicating with servers while transmitting any message from client to server. then, what is HTTPS? HTTPS is a secure version of HTTP. "s" is Secure in HTTPS. In HTTPS the data sent is encrypted, so that people don't see the message transmitted over the network. By using the secured version the data sent or received is completely encrypted and no one can impersonate it. When we access a website, our browser sends requests to the server and then the server gives the response in the form of web pages. webpages consist of images, audio, video, html files, and more. How do we access a website? When we access a website, the browser sends a request to a web server and downloads the responses. You need to tell the browser specifically from where to access the resources, this is where the URLs help. URL is a uniform Resource Locator which gives instructio...

What is TCP/IP Model??

What is TCP/IP Model?? TCP stands for Transmission Control protocol/Internet Protocol . It is a communication protocol used to interconnect the devices in the internet. Initially, the Transmission Control Program provided only a common service to its users, not datagram. As experience with the protocol grew, functionality was divided into layers of distinct protocols, allowing users direct access to service.  TCP provides reliable, ordered delivery of  bytes between applications running on hosts communicating via network. TCP is connection oriented means a connection is established between a client and server before data is sent. The server waits for the connection requests from clients before any connection is formed.  TCP/IP has 5 layers  Application Layer : This layer allows the user to interact with the application.  Transport Layer : This layer is responsible for flow control, the data is sent through this layer. Network Layer : This layer is responsible f...
