Description
PREVIEW THIS EBOOK
Take a look inside and explore a selection of pages before you buy.
Understand modern cyber threats—and learn how to make safer decisions about your accounts, information, devices, and business systems.
Cybersecurity involves more than installing software or choosing a strong password. It also depends on how people verify requests, manage access, handle sensitive information, and respond when something goes wrong.
Computer Security brings these elements together in a practical English-language handbook and workbook. Across 60 chapters and 320 pages, it combines clear explanations, fictional case studies, guided activities, annotated answers, and implementation tools to help you put security principles into practice.
Recognize deception and strengthen human defenses
Explore the psychological pressures behind social engineering, including urgency, authority, fear, and misplaced trust. Learn how to assess phishing and spear phishing messages, executive payment fraud, telephone manipulation, identity impersonation, emotional scams, and suspicious USB devices.
Discover practical verification habits that help people pause, check consequential requests, and report concerns confidently.
Build stronger everyday protection
Understand authentication, passkeys, multifactor authentication, least privilege, operating system hardening, patch management, network segmentation, application security, cloud responsibilities, encryption, and key management.
Learn why backup success does not necessarily mean successful recovery—and how to connect technical controls to the services people actually need.
Understand emerging threats
Examine how stolen access and leaked information can support fraud, impersonation, and extortion. Explore AI-enabled deception and the risks of giving AI tools excessive data or authority.
The book also explains how to assess data exposure, preserve useful evidence, and communicate uncertainty accurately.
Explore mobile application security
Work through the OWASP Mobile Top 10 2024 risk categories and understand the distinct roles of MASVS, MASWE, and MASTG.
Topics include credentials, dependencies, authentication and authorization, input handling, network trust, privacy, binary resilience, release configuration, local storage, and cryptography. Android chapters address platform architecture, version-aware testing using Android 16 and 17 reference points, managed devices, and assessment planning.
A fictional mobile delivery service connects these lessons to a practical release decision.
Discover connected vehicle cybersecurity
Explore vehicle architecture, domain isolation, secure diagnostic gateways, software updates, fleet services, and location privacy.
Learn what isolated “cars in boxes” test benches can demonstrate, why their fidelity matters, and how to interpret their limitations.
Apply structured risk analysis
Follow a guided introduction to ANSSI’s EBIOS Risk Manager through its five workshops: scope and security baseline, risk sources, strategic scenarios, operational scenarios, and risk treatment.
The fictional Meridian Care study shows how to connect business values, technical conditions, treatment actions, and residual risk decisions.
Learn through practice
Each chapter includes explanations, practical controls, a worked case, reasoning questions, a guided activity, and a review record. A glossary, reference directory, and four integrated capstone exercises help you consolidate what you learn.
Build a clearer understanding of security—and turn that understanding into practical, verifiable action.
