What is Cyber Security?

Cybersecurity is the practice of protecting sensitive data and critical systems like computers, servers, networks, and more from cyber threats and malicious attacks. As technology advances and computers change, the cybersecurity field continues to expand. 

At Routledge, we are proud to publish top quality books discussing the latest cyber awareness and security updates and changes.

Below are a few of the most prominent components of cybersecurity today.

Network Security

Network security refers to the policies and procedures used to prevent, detect and defend your network from attacks such as unauthorized entry, misuse, and theft. Creating a secure infrastructure allows users to operate securely without the threat of a security breach.

Information Security

Information security, or InfoSec, refers to the specific practices and tools designed to protect sensitive information from threats like unauthorized viewership and unlawful modification by intercepting information risks.

Infrastructure Security

To protect an organization from threats like data leaks and stolen intellectual property, you must protect its technology infrastructure. Infrastructure security employs assets such as end-user devices, data center resources, networking systems, and cloud resources to protect against cybersecurity threats.

Application Security

Application security refers to a set of safety measures that ensure a secure life cycle, from development to employment, for application software. Application security aims to improve general security practices and prevent an application's data and code from being stolen or hijacked.

Cloud Security

Cloud security is a set of policies, technologies, and services designed to manage threats to business security. It protects an organization's intellectual property, data, and applications hosted over the Internet and is essential as organizations incorporate more and more cloud-based tools and services in their infrastructure.

What is a Cyber Attack?

Cyber attacks are malicious attempts to steal, expose, change, or destroy data through unauthorized access to computer systems. Hackers and cybercriminals use various methods to launch cyber attacks, including malware, ransomware, and social engineering.

Learn more about a few of the most common cyber attacks below.


Malware is software designed to damage and disrupt computers, servers, and networks. It may be used to leak private data, deny users access to their system's information, or interfere with a network's security. Types of malware include Trojans, viruses, spyware, and ransomware. 



Ransomware is malware that restricts users' access to a computer's files and threatens to publish personal data or block entry until the victim pays a ransom. While simpler ransomware may lock the computer system without sabotaging files, more advanced malware encrypts the computer's files using cryptoviral extortion.

Social Engineering

Social engineering is the act of psychologically manipulating computer users into giving away confidential information. Unlike other types of cyber attacks, social engineering relies on human error rather than faults in computer systems. The kind of details cyber criminals seek often include passwords, bank information, and other personal details.
