Understand the threats. Learn the defenses. Build a stronger foundation in Network Security.Modern organizations depend on computer networks for communication, business operations, cloud services, applications, and data exchange. With this growing connectivity comes an equally important challenge: protecting networks from unauthorized access, attacks, vulnerabilities, and security incidents.Network Security: A Comprehensive Guide for Beginners and Advanced Learners provides a structured learning journey for students and aspiring security professionals who want to understand how modern networks are protected.The book begins with the fundamentals of networking and network security, covering network topologies, OSI and TCP/IP models, network devices, IP addressing, subnetting, protocols, and ports. It then moves into common cyber threats and vulnerabilities, including malware, phishing, social engineering, DoS and DDoS attacks, Man-in-the-Middle attacks, weak authentication, and software vulnerabilities.Readers will learn important security principles such as the CIA Triad, AAA, Defense-in-Depth, Least Privilege, and Risk Management, followed by an introduction to cryptography, encryption, digital signatures, certificates, TLS, IPsec, and PKI.The book also explores firewalls, IDS, IPS, SIEM, VPNs, wireless security, Network Access Control, web application security, HTTPS, secure development practices, incident response, digital forensics concepts, disaster recovery, and business continuity.The final chapters look toward the future, introducing Zero Trust, Next-Generation Firewalls, AI and Machine Learning in cybersecurity, Cloud Security, and IoT Security.For students, the book provides a strong academic foundation. For aspiring professionals, it introduces important technologies, responsibilities, career paths, and security practices.The goal is not simply to learn how attacks occur, but to understand how responsible security professionals identify risks, protect systems, respond to incidents, and continuously improve security.Learn the fundamentals. Understand the risks. Think like a security professional.

The plugin was deleted. The malware came back. This real WordPress investigation shows why. Follow a multi-layer infection across plugins, MU plugins, drop-ins, theme code, database records, memory, recovery archives, administrator access, and browser persistence—and learn how to remove the recovery system instead of deleting one visible symptom.

Short Description of the BookSecuring Modern AI Applications is a practical guide to securing LLM-powered applications, RAG systems, AI agents, and modern AI development environments.The book explains AI-specific threats such as prompt injection, data leakage, RAG poisoning, insecure tool use, agent abuse, and AI supply-chain risks while also covering traditional application security, privacy, governance, secure development, monitoring, testing, and red teaming.Designed for developers, AI engineers, cybersecurity professionals, architects, and technology leaders, the book focuses on practical principles that remain useful as AI technologies continue to evolve.Build AI. Secure AI. Govern AI.

See what your network traffic is really revealing. This practical guide breaks down TLS fingerprinting, JA3/JA4 and HTTP client identification, then shows you how to put them to work with Python, Go and Rust. From protocol internals to production pipelines, learn how to identify clients at scale without losing sight of privacy or operational reality.

Get inside running software and see what it’s really doing. Mastering Frida takes you from your first hook to building serious instrumentation tools for Windows, Linux, macOS, Android and iOS. Learn how Frida works under the hood, where platforms differ and how to use its power without getting burned.

A hacked WordPress site can look perfectly normal. Follow real investigations across files, databases, hidden users, cron jobs, hosting, DNS, checkout pages, and blacklists—and learn how to find the full compromise, remove it safely, and stop it from coming back.

Ein Playbook gegen die agentische Drift — 29 Leitplanken, um KI-generierten Code prüfbar, ehrlich und auditierbar zu halten, destilliert aus über 27 Jahren Projekt- und Programmleitung in regulierten Branchen.

AI coding agents can build, run and break things at machine speed. This book shows you how to contain them safely. From Linux isolation and microVMs to WebAssembly, threat modeling and incident response, you’ll learn how to design production-grade sandboxes that let autonomous agents execute code without putting your systems at risk.

The security failures specific to AI-generated code, each paired with its fix. Hardcoded secrets, broken RLS policies, hallucinated packages, prompt injection, plus a 25-point pre-launch audit.

Implementing ISO/IEC 27001:2022 is easier with the right guide. Packed with practical steps, ready-to-use templates and real-world examples, this book helps you build, manage and certify an effective Information Security Management System with confidence.

Smart cards power secure payments, digital identity and trusted authentication around the world. This book is a practical guide to building secure applications for ISO/IEC 7816 and ISO/IEC 14443 systems with real code, hands-on examples and proven development practices.

A test-by-test playbook that turns Maester's 676 security checks into risks you understand and fixes you can run.

This book is a workshop where things go wrong on the page, in front of you, and then get fixed in code, with the output that proves the fix worked. There's no need to be a security expert to follow along. We'll be moving from the interpreter to the supply chain, from the token to the human clicking Allow, and from a single tool to a whole host of untrusting servers.

Build offensive security tools that go beyond simple scripts. BlackHat Ruby shows how to create scanners, fuzzers, protocol analyzers and exploit frameworks with clean, practical Ruby code. Along the way you'll see how these techniques work, where the legal boundaries are and how defenders spot and stop them.
