Verified bibliography

Technical books published from 2024 through 2026.

The descriptions below explain each title's practical scope in Zeph Tech's own words. Publication facts and links are tied to the publisher catalog.

2026 · Networking

CompTIA Network+ (N10-009) Certification Companion

Hands-on Preparation and Practice Guide

A 368-page networking companion covering networking fundamentals, implementations, operations, security, troubleshooting, wireless, hardening, monitoring, cloud and virtualization, physical security, documentation, policy, and exam preparation.

This title is especially relevant to Zeph Tech's infrastructure and cybersecurity work because it treats networking as an operating discipline: configuration, monitoring, troubleshooting, change management, resilience, security, and documentation all have to work together.

2025 · Security analytics

CompTIA CySA+ Certification Companion

Hands-on Preparation and Practice Guide

A 472-page cybersecurity analytics and operations companion focused on security monitoring, risk, vulnerabilities, incident analysis, response, and the practical reasoning expected of defensive security professionals.

The operational emphasis aligns closely with Zeph Tech guidance that asks teams to preserve evidence, distinguish findings from assumptions, prioritize remediation, and connect technical signals to accountable decisions.

2025 · Cybersecurity foundations

CompTIA Security+ (SY0-701) Certification Companion

Hands-on Preparation and Practice Guide

Coauthored with Kyle Reis, this 501-page book covers Security+ domains including threats, vulnerabilities, architecture, security operations, incident response, risk management, governance, and security program concepts.

Its broad security scope mirrors a central Zeph Tech principle: cybersecurity cannot be reduced to one tool or one team. Architecture, identity, operations, suppliers, governance, response, and evidence all contribute to the risk picture.

2024 · IT operations

CompTIA A+ Certification Companion

Hands-on Preparation and Practice for Exams 220-1101 & 220-1102

A 378-page IT foundation covering hardware, operating systems, software, support, troubleshooting, cloud and virtualization, mobile devices, networking, printers, and security.

A+ subject matter is intentionally practical. Reliable technology programs depend on the less glamorous work too: endpoint support, change discipline, documentation, physical devices, user impact, diagnostics, and repeatable troubleshooting.

2024 · Cybersecurity

Cybersecurity Essentials

Practical Tools for Today's Digital Defenders

A 491-page cybersecurity book spanning foundational security, ethical hacking concepts, defensive practice, cryptography, cloud, IoT and mobile security, social engineering, incident response, business continuity, disaster recovery, and legal and compliance considerations.

The breadth is useful context for Zeph Tech's research model: technical controls matter, but so do recovery, people, governance, legal context, and the operational ability to sustain protections after deployment.

Author profile

From publication to public resource

The books are not presented as proof that every Zeph Tech conclusion is correct. They are evidence that the site's research lead has completed substantial, externally published technical work in the same domains the site covers.

For a reader, the more important test remains inspectability: can a material claim be traced to the right source, can the publication date and scope be understood, and can the recommended action be challenged or adapted?

Subject coverage

The bibliography supports a wide operating range.

Across the five titles, the recurring themes are the same ones that show up in real technology operations: understand the system, document it, secure it, monitor it, troubleshoot it, govern change, and prepare for failure.

Networking & infrastructure

Protocols, switching and routing concepts, wireless, monitoring, troubleshooting, cloud, virtualization, physical infrastructure, network management, and documentation.

Cybersecurity operations

Threats, vulnerabilities, hardening, monitoring, security analytics, incident response, recovery, risk management, and security governance.

IT support & lifecycle

Hardware, operating systems, endpoint support, practical troubleshooting, change awareness, user impact, documentation, and service continuity.

Editorial connection

Experience informs the questions; sources support the claims.

Zeph Tech intentionally separates author experience from factual authority. Practical experience helps identify the questions that matter: who owns the control, what evidence exists, what fails during transition, what a vendor has actually demonstrated, which dependency can stop service, and what decision must be documented. But current laws, standards, product capabilities, vulnerabilities, deadlines, and technical specifications still require current evidence.

That distinction is especially important in fast-changing fields. A book published in 2024 or 2025 can establish durable technical foundation and professional authorship without being treated as the current authority for a 2026 regulation, product release, security advisory, or implementation deadline.

Verification note

Publisher records are linked directly.

Zeph Tech does not ask readers to accept this bibliography solely from a company biography. Each title links to Springer Nature's public catalog entry, which provides the publisher's bibliographic record, author attribution, edition information, ISBNs, page count, publication dates, and available table-of-contents details.

If a publisher record changes, the publisher record controls. Please use the correction path if a bibliographic detail on this page needs to be updated.
