الأمن السيبراني لعام 2025

Cybersecurity 2025: Principles, Practice, and Proactive Strategy is your practical guide to surviving—and thriving—on tomorrow's digital battlefield. This book presents five compelling parts in one practical read. Part One carefully analyzes the threat landscape of 2025: states, ransomware-as-a-service, AI-powered deepfakes, and a new “proactive” mindset that trumps detection and response. You'll learn about the new governance function in the NIST CSF 2.0 Cybersecurity Framework, Parker's Hexagon Model, the Saltzer-Schröder Principles, and STRIDE Threat Modeling. Part 2 delves into attack methods - TCP/IP hijacking, buffer overflow, XSS attacks, SSRF attacks, side channels, and browser data leaks. Part Three moves into Blue Team operations: Security Operations Center workflows, incident response plans, digital forensics, SIEM labs using Splunk, and the foundations of zero trust. Part 4 equips the red team: the MITRE ATT&CK framework, nmap tools, Nessus, Metasploit, and lotL ethical tactics. Part 5 covers the latest developments in cloud computing, including shared liability, IoT botnets, IoT convergence, AI malware, model poisoning, as well as risk management, compliance and governance, policy writing, and a capstone project in the picoCTF competition. Each chapter ends with a practical exercise, simulation, or software application that you can implement today.
