Cybersecurity is a process to save the networks, computer programs, and data from the illegal access or users that aim to access users data for personal uses and benefits. For the protection of data, many organizations develop a software. This software help to protect the data and information. Cybersecurity playing a big role in developing a technology and other services like the internet. we only think about the ‘cybersecurity’ whenever we listen to the cyber crimes. This paper describes the cyber security, cyber attack, types of cyber attacks, and major area in cybersecurity.
Cyber combine form relating to information, the internet and virtual reality cybersecurity is necessary since it helps in securing data from threats such as data theft or misuse, also safeguard your system from virus. The term cybersecurity is used to refer to the security offered through online services to protect your online information with an increasing amount of people getting connected to the internet, the security threats that cause massive harm are increasing also. In India, we went straight from no telephones to the latest in mobile technology says Cherian Samuel of the Institute for Defence Studies and Analysis,(IDSA)in New Delhi and the same with internet connected computers Cybersecurity was designed to help learners develop a deeper understanding of modern information and system protection technology and methods. In information technology, data protection or information security is one of the great challenges of the world.
Cybercrime has led to the loss of billions of dollars, malfunctioning of a computer system, the destruction of critical information, the compromising of network integrity and confidentiality, etc. Cybercrime:-cyber crime, or computer oriented crime, is a crime that involves a computer and a network cybercrime also called computer crime, is an illegal activity that involves a computer or network connected device, such as a mobile phone. The Department of justice divides cybercrime into three categories: crimes in which the computing device is the target, for example, to gain network access; crimes in which the computer is used as a weapon, for example, to launch a denial of service (DoS) attack; and crimes in which the computer is used as an accessory to a crime, for example, using a computer to store illegally-obtained data.
Major areas of cybersecurity Application security: Application security is to hold within measures that are taken in the development of the life cycle to prevent the applications from threats and attacks that come in the application design developments and maintenance. Application security ways are: a)Input parameter validation. b)User Authentication. c) Session management, parameter manipulation & exception management. d) Auditing and logging. Information security: Information security protects information from unauthorized access to avoid identity theft and to protect privacy.
Major techniques used to prevent this are:
Disaster recovery is a process that includes performing risk assessment, establishing priorities, developing recovery strategies in case of a disaster. all business should have a concrete plan for disaster recovery to resume normal business operations as soon as possible after the disaster.

The effective network security targets a variety of threats and stops them from entering or spreading on the network. Network security components are: a) Anti-virus and anti-spyware, b)Firewall, to block unauthorized access to your network. c)Intrusion prevention systems (IPS). d) Virtual Private Networks (VPNs) for providing secure remote access.
A cyber attack is carefully exploitation of computer systems, technology dependent on the networks and enterprises. Cyber attacks use harmful code to change the computer code or data, resulting in disturbing of the importance that can arrangement data and leads to cyber crimes, like identity and information theft. Cyber Attacks are also called computer network attack (CNA). Types of attacks in cybersecurity identity theft: Identity theft is the act of a person obtaining information illegally about someone else. Thieves and hackers try to find such information as full name, maiden name, address, date of birth, social security number, passwords, phone number, email, and credit card numbers.

Malware is simply defined as code with malicious intent that typically steals data or destroys something from the computer. Malware is mostly entered into the system through email attachments, software downloads from the internet.

It is term designed forget the information secretly about the user activity. Spyware programs are used to track users’ habits to better target them with advertisements. Spyware is usually installed onto the user’s machine without them knowing when a link is followed by them which redirects the user to a malicious website. Prevention from the spyware.
The system is affected with the spyware by visiting the infected website, downloading infected software etc. Download from well-known and reputable sites only. Use a firewall for enhanced security. Maintain anti-virus and anti-spyware updates. Phishing:- phishing attacks are attacks that are sent through email or pop messages and ask users to click on a link and enter their personal data. It will attract the user according to their interest and when the user clicks on the link then the hanker will able to enter the system and stole the data and personal information from the system. Denial-of-service A DoS attack focuses on disrupting the service of a network. Attackers send high volumes of data or traffic through the network until the network becomes overloaded and can no longer function and stop functioning. The common DOS attacks are DDOS (distributed-denial-of-service ) it will also send the high volume data and traffic on services until server and network stop working. There are two types of DOS attacks: flooding services and the crashing services.
Flood attacks occur when the system find too much traffic for the server to buffer, causing them to slow down and ultimately stop. The most Popular flooding attacks are: Buffer overflow attacks, ICMP flood, SYN flood, crashing services, DoS attack, s simply blame that cause the target system or service to get crash. In these attacks, the input is sent that takes advantage of bugs in the target that subsequently crash or severely destabilize the system so that it can’t be accessed or used. Password sniffing When hankers not able to guess your password then they try they another method called Password sniffing. In this, the attacker uses the software and try to access your data and information but the software is running on their own machine ,they are trying to get your password and username when they get the access in it they are able to get access in your system and network.
Website defacement is the attacks usually done on the websites. These attack on a website that changes the visual appearance of the site or a webpage. This is basically done by hackers and destroyers, they will replace the webpage and server with their own webpage and site. There are different desires of attackers which lead to deface the website, one of them is a political motivation the attackers who do this type of activities are called hacktivists they may change the content of the website with message picture and another text of their own choice.
