Cyber Security

Mobile apps handle some of our most sensitive data, making security essential. Mobile Application Security explores how Android, iOS and cross-platform apps are attacked and secured. Covering secure coding, cryptography, reverse engineering and penetration testing, it gives developers, security professionals and students the practical skills to build and assess secure mobile applications.

AI governance is moving from principle to practice. This hands-on guide shows you how to build, implement and certify an ISO/IEC 42001 AI management system with confidence. From clause-by-clause guidance to practical templates, integration strategies and real-world scenarios, it turns a complex standard into a clear path from foundation to certification.

In Google Cloud, the compromised system you need often disappears before you can touch it. This practitioner's guide shows you how to pursue attackers through Cloud Audit Logs, IAM, and ephemeral infrastructure instead, with runnable gcloud commands and BigQuery queries for every step.

Azure investigations don't start with a disk image, they start with the control plane. This field guide walks incident responders through Azure's logging architecture, identity attack chains, VM and container forensics, and evidence acquisition at cloud scale, with three full attack scenarios worked end to end.

A field-tested, platform-agnostic methodology for proactive threat hunting, from hypothesis formation and data foundations to a full scenario library organized by MITRE ATT&CK tactic. Every technique ships as portable Sigma YAML or pseudocode, built to outlast whichever SIEM or EDR you run today.

Security engineering is about building systems that stay secure when things go wrong. This book covers the fundamentals of secure applications, infrastructure and operations through practical examples, real breaches and proven security practices.

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.

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.

Build web scrapers that survive the real world. This hands-on guide takes you from Scrapy fundamentals to scalable production systems, with practical patterns for asynchronous crawling, clean data pipelines, testing, deployment and resilient architectures. Packed with runnable Python examples, it gives you the skills to scrape smarter, faster and at scale.

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.

AI can write code in seconds, but can you trust what it creates? Securing AI-Generated Code shows you how to uncover hidden vulnerabilities, stop risky dependencies, secure AI coding agents and build safer development pipelines. A practical guide for teams that want the speed of AI without putting security on the line.

What if your software could compute on sensitive data without ever seeing it? Private Computing with Homomorphic Encryption takes you from the core ideas to working, production-minded systems. Learn the math, schemes, libraries and design patterns you need to build with HE, judge its tradeoffs and know when it is the right tool for the job.

This playbook was prepared by SkelerSecurity to equip founders, executives and developers of earlystage healthcare, financial technology and adjacent high-trust ventures with the security mindset, the controls, and the business case they need to operate safely in a threat environment that has industrialized.

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.

Build fast, secure and portable applications with WASI. Start with the fundamentals, then move into components, WIT, Wasmtime and real production patterns using Rust, C, Go and JavaScript. From sandboxed plugins to serverless and edge workloads, this practical guide gives you the skills to take WebAssembly from your first experiment to production.
