What is Cyber Security and what are its types?

Cyber Security defines the technologies, procedures, and practices created to protect networks, devices, apps, and data from any type of cyber-attacks. Cyber security can be defined as information technology (IT) security.

Cyber Security is all about preserving your devices and network from unauthorized access or alteration. The internet is not only the essential source of data, but it is also a channel through which people do business.

The goal of cyber security is to protect computers, networks, and software programs from such cyber attacks. Most of these digital attacks are aimed at assessing, altering, or removing sensitive data; extracting money from victims; or interfering with normal business operations.

Types of Cyber Security

The types of cyber security are as follows −

Information Security

The main objective of Information security is to protect the users' private data from unauthorized access, identity fraud. It protects the privacy of information and hardware that manages, saves, and transmits that information. Examples of Information security contain User Authentication and Cryptography.

Application Security

Application security goals to protect software applications from vulnerabilities that appear because of the flaws in application design, development, installation, and update or maintenance procedure.


Malware can define the malicious application, involving spyware, ransomware, and viruses. It generally breaches networks through a vulnerability, such as clicking on a suspicious email connection or installing risky software. Once inside a network, malware can receive sensitive data, further make more harmful software throughout the framework, and can even block access to vital business network elements.

Network Security

The main objective of Network security is to protect the usage, integrity, and security of a network, associated elements, and data transmitted over the network. When a network is achieved, potential threats get blocked from introducing or extended on that network.

An example of Network Security contains Antivirus and Antispyware programs, a firewall that blocks unauthorized access to a network, and VPNs (Virtual Private Networks) used for secure remote access.

Identity Theft

It is a type of cyber security threat that contains the stealing of personal data of the victims from social media websites including Facebook, Instagram, etc., and using that data to construct an image of the victims. If adequate sensitive data is assembled it can enable the cybercriminal to impersonate you in some method.

Password Attacks

It is a type of cyber security threat that contains a hacking attempt by hackers to crack the passwords of the user. With the support of a hacking device, hackers can introduce several passwords a second to crack the victim’s account credentials and grow access. Hackers can also implement password attacks on a computer login screen to boost access to a victim's computer and the data saved in it.
