Bell-Forge B: Fachkraft/Servicekraft für
Schutz und Sicherheit

Fachkraft/Servicekraft für Schutz und Sicherheit

2: Wissensbasis für Ausbildung und Berufspraxis (Fachkompetenzbuch)

Zielgruppe
Berufliche Gymnasien in Niedersachsen, die im Mathematikunterricht den Beruflichen Schwerpunkt Wirtschaft (Nicht-Technik) gewählt haben.

Gesamtkonzeption
Die dreibändige Reihe Mathematik für das BG in Niedersachsen - Kerncurriculum und Bildungsstandards basiert auf dem Kerncurriculum (2018) und den Bildungsstandards im Fach Mathematik für die Allgemeine Hochschulreife (2012). Die drei Bücher werden durch drei Arbeitshefte, drei Lehrerbegleitbücher sowie eine für das Abitur zugelassene Formelsammlung ergänzt. Die Reihe ist vollständig auf den Einsatz eines Computer-Algebra-Systems (CAS) umgestellt worden.

Die Autorin berücksichtigt bei der Erstellung dieser Bücher die inhaltsbezogenen und die prozessbezogenen Kompetenzen, die die Schülerinnen und Schüler gemäß Kerncurriculum während der drei Jahre am Beruflichen Gymnasium erwerben sollen. Der in der BbS VO bzw. EB BbS VO verankerten Handlungsorientierung wird ebenso durchgängig Rechnung getragen wie der Berufs- und Problemorientierung sowie der Kompetenzorientierung.

Jedes Hauptkapitel beginnt mit berufsbezogenen Lernsituationen gemäß SchuCu-BBS 2024 und DU-BBS, die die Schülerinnen und Schüler eigenverantwortlich und selbstorganisiert mithilfe der Informationstexte, Informationsvideos, GeoGebra-Dateien und der Beispielaufgaben aus den nachfolgenden Abschnitten des Buches bearbeiten und sich so die notwendigen Kompetenzen aneignen können. 

Jede Lernsituation umfasst nicht nur die zugrunde liegende berufliche Handlungssituation, sondern auch problemorientierte sowie Operatoren gestützte Aufgabenstellungen. Neben den Hinweisen auf die benötigten und die zu erzielenden Kompetenzen werden Hinweise zur Bearbeitung und ergänzend Hinweise für die Umsetzung im Distanzunterricht gegeben. Im zugehörigen Lehrerbegleitbuch finden sich die entsprechenden Zielbeschreibungen, die Kompetenzraster sowie eine mögliche Musterlösung. 

Um die in den Handlungssituationen benötigten Fähigkeiten und Fertigkeiten im Nachgang zu trainieren und zu festigen, enthalten das Buch und das Arbeitsheft eine Vielzahl verschiedener Übungsaufgaben, die je nach Aufgabentyp händisch und/oder mit einem Computer-Algebra-System (CAS), analog oder digital gelöst werden können und durchgängig mithilfe von Operatoren formuliert werden. Dadurch wird zielgerichtet der Kompetenzaufbau erreicht und die Schülerinnen und Schüler, die am Zentralabitur Mathematik teilnehmen werden, können die Aufgaben des hilfsmittelfreien Teils (Prüfungsteil A) und des Teils mit Hilfsmitteln (Prüfungsteil B) adäquat und sachgerecht bearbeiten. 


Die Reihenfolge der einzelnen Kapitel kann als Basis für den Aufbau des schulinternen Curriculums und der Jahresplanung dienen, muss sie aber nicht, da die Autorin darauf geachtet hat, dass die mathematischen inhaltsbezogenen Kompetenzen gemäß Spiralcurriculum in die Berufsbezüge integriert werden. 
Das Schulbuch enthält außerdem Schritt-für-Schritt-Anleitungen zur Anwendung von GeoGebra..

Dark Water Disappearance (West Investigations) / Tangled Threat

A Trap For Two: The Sinful Sleuths Club

If your tooling is public, it’s already known. Defenders have studied every public offensive framework. They know Cobalt Strike’s beacon patterns, Metasploit’s shellcode signatures, and the behavioral fingerprints of every commodity implant. Once it’s known, the tool gets burned. As a red teamer, your job is to get in. When defenders know your tools, they know your moves—and you don’t get in. Evasion Engineering teaches you to build custom offensive tooling in Go by understanding what modern defenses actually target and building around them.&nbsp; You’ll construct network enumerators, C2 implants, lateral movement tools, obfuscated loaders, and covert exfiltration channels. Each chapter then flips the perspective: the same techniques, examined from the detection side. Build the tool. Understand how it gets caught. Build better. Dennis Chow (GIAC Security Expert #288) and Michael LaSalvia bring 36 combined years of experience inside Fortune 500 red team programs. They treat payload development as an engineering discipline: robustness, reusability, and reliability built in from the start, not bolted on after the fact. You’ll learn to: <ul><li>Build enumeration tools that don’t match known signatures&nbsp; </li><li>Develop C2 implants with custom protocols that bypass network inspection </li><li>Implement lateral movement via autonomous worm mechanics </li><li>Create hybrid-packed payloads that defeat AV and EDR </li><li>Exfiltrate data through covert channels under active monitoring </li><li>Map every technique to its detection surface and validate your results </li></ul> If you’ve been relying on tools the defender already knows, this book is where that changes.&nbsp; Requires Go 1.21.x and higher and Python 3.x

A practical, detection-aware guide to designing and building custom red team tools that survive in modern enterprise environments. Red Team Toolcraft teaches offensive and defensive security professionals how to reason about tooling behavior through the lens of SIEMs, EDRs, and logging pipelines, and how to use that insight to build bespoke tools engineered for evasion rather than convenience. Modern enterprises are saturated with telemetry. Endpoint agents, centralized logging, behavioral analytics, and automated detections have made off-the-shelf red team tools increasingly brittle and predictable. Most red team tools fail not because they’re buggy, but because they behave in ways detection systems are designed to notice. Red Team Toolcraft teaches readers how to think, design, and build differently. Instead of showing how to run popular frameworks, this book focuses on how offensive tools actually behave in monitored environments and why that behavior so often gives them away. The authors walk readers through the foundations of detection-aware tool design, explaining how payload structure, execution flow, and environmental interaction influence visibility across modern detection stacks. Each chapter centers on modular, adaptable examples that show not just what works, but why it works. Readers learn how small design decisions surface in logs, alerts, and behavioral analytics, and how thoughtful toolcraft can reduce detection while still achieving realistic adversary objectives. The result is a field-ready reference for red teamers who need to build their own tools when public ones fail, and for detection engineers and threat hunters who want a clearer view of how advanced operators design tooling to evade automated defenses.

Building Custom Tools to Evade Modern Detection

Evasion Engineering

A deep exploration of the opportunities and risks a global digital economy poses for refugees. Digital Exiles opens a rare window into the world of refugees trying to survive and thrive in an increasingly digitalized and technological world of work. Often excluded from local employment and struggling to make ends meet, refugees are increasingly dependent on digital jobs and online work as a financial lifeline. Andreas Hackl offers a human-centered and global perspective to these struggles through his research into three of the most important refugee-hosting countries: Lebanon, Kenya, and Germany. The pursuit of a digital livelihood—from attending coding schools in Berlin to training datasets for AI in crisis-stricken Lebanon to online freelancing in Kenya’s refugee camps—represents an increasingly important income opportunity for refugees. Digital work programs by aid organizations and the private sector aim to help the forcibly displaced become self-reliant and successful workers, yet, for many, it creates new forms of exclusion, precarity, and risk. Combining human stories with insights from five years of multisited research and applied work with leading organizations, the author presents an alternative vision of an inclusive world of work that can help shape the fair digital economy of the future.

Small Changes that Will Make You Rich

The Wealth Habit

A personal chronicle of three key legal privacy battles that have defined the digital age and shaped the internet as we know it. From a seasoned leader in the field of digital privacy rights. Throughout her career, Cindy Cohn has been driven by a fundamental question: Can we still have private conversations if we live our lives online? Privacy’s Defender chronicles her thirty-year battle to protect our right to digital privacy and shows just how central this right is to all our other rights, including our ability to organize and make change in the world. Shattering the hypermasculine myth that our digital reality was solely the work of a handful of charismatic tech founders, the author weaves her own personal story with the history of Crypto Wars, FBI gag orders, and the post-9/11 surveillance state. She describes how she became a seasoned leader in the early digital rights movement, as well as how this work serendipitously helped her discover her birth parents and find her life partner. Along the way, she also details the development of the Electronic Frontier Foundation, which she grew from a ragtag group of lawyers and hackers into one of the most powerful digital rights organizations in the world. Part memoir and part legal history for the general reader, the book is a compelling testament to just how hard-won the privacy rights we now enjoy as tech users are, but also how crucial these rights are in our efforts to combat authoritarianism, grow democracy, and strengthen other human rights.

<div>Human history is a history of individuals - of kings and queens, of leaders and thinkers and of the many individuals who struggle, work hard and find their paths in life. It is also the history of individuation, understood as a continuous search for autonomy, self-affirmation and the achievement of personal goals. But today, this process of individuation is coming to an end and morphing into its opposite - disindividuation. The individual is giving way to the progressive loss of individuality and social life is turning into the society of "dividuals" - that is, beings who are becoming unaware of their uniqueness and who are losing their sense of self.&nbsp;</div> <div>&nbsp;</div> <div>The main driver of this process is technology. The more that individuals rely on technological devices to fill the social void and mitigate loneliness, the more they are recognized not so much for themselves but as the bearers of the devices that contain all the information necessary for their identity: images, texts and the digital traces of earlier exchanges. Individuals increasingly renounce their privacy, sharing it with a device that becomes an integral part of themselves. Deprived of uniqueness, the dividual is a lonely being who no longer has the ability to relate effectively to others and to external reality. We move towards a future without hope, immersed in the ever-innovative flow of information on screens, content to survive the present, as if nothing mattered.</div> <div>Human history is a history of individuals - of kings and queens, of leaders and thinkers and of the many individuals who struggle, work hard and find their paths in life.

Learn How to Make Wireless Work Wi-Fi, Bluetooth, and LoRa are technologies that power our world, but building with them isn’t always straightforward. Connections drop, tutorials skip steps, and error messages don’t always help resolve problems. Through a series of hands-on projects using Raspberry Pi and Linux, you’ll learn how wireless systems work, how to control them, and how to build tools that actually function in the real world. Each recipe is self-contained, reliable, and ready to adapt for your own projects. Among the book’s many projects, you’ll build: <ul><li>A BLE audio receiver for high-quality wireless sound</li><li>A battery-powered LoRa node with miles of range</li><li>A mesh Wi-Fi network that reroutes itself</li><li>A signal strength display with a mini TFT screen</li><li>A wireless intrusion detection system and captive portal</li></ul> Along the way, you’ll build a solid foundation in Linux networking, gain fluency in wireless protocols like 802.11, BLE, and LoRaWAN, and develop the confidence to design and deploy your own solutions. Each recipe is built around a wireless challenge you’re likely to encounter and gives you the tools to solve it. It’s wireless. It’s Linux. And with this book, it finally makes sense.
