Cyber Security: Learn the Basics of Cyber Security, Threat Management, Cyber Warfare Concepts and Executive-Level Policies

Cybersecurity touches everyday digital habits as well as the policies and safeguards organizations put in place. This introductory overview brings those perspectives together, tracing common threats and cybercrime while explaining the security practices individuals and businesses can consider.

Noah Zhang and Dana Onyshko move from foundational concepts to practical subjects such as password handling, backups, phishing awareness, access controls, and risk assessment. The result is a broad orientation to cybersecurity, with attention to both personal protection and organizational responsibility.

From cyberspace to cyber threats

The opening chapters introduce cybersecurity principles and why they matter, then set cyber threats in context. The book also distinguishes the internet from the web and outlines layers and characteristics of cyberspace—useful framing for readers who want to understand the environment in which digital risks arise.

Security, crime, and cyberwarfare

Further chapters cover computer and network security, identity theft, data breaches, the dark web, and forms of cybercrime including email spoofing, forgery, defamation, and cyberstalking. A separate section examines cyberwarfare, including its history, weapons, and defensive considerations.

Practical safeguards for people and organizations

The countermeasures discussed include multifactor authentication, secure password practices, least-privilege access, backups, phishing awareness, and monitoring privileged or third-party access. Business-focused chapters extend that discussion to employee training, risk assessment, written policies, firewalls, antivirus software, software updates, and mobile-device security.

A broad starting point for cybersecurity readers

With its mix of foundational concepts, threat awareness, and organizational practices, this book may suit curious general readers, business owners, and people exploring cybersecurity as a field. Its contents also list bonus sections on wireless security and small-business cybersecurity. Because the subject changes quickly, treat the book as an introduction rather than a source for current threat intelligence.
