Curriculum Overview: Detailed Course Breakdown

Unix System Architecture

The core of Unix forms the foundation upon which secure computing stands. In this module, we delve deep into the Unix System Architecture, exploring how its layered design supports a secure and robust environment for computer network operations. We'll dissect the user interface, kernels, hardware abstraction layer, and the shell environment, understanding how each layer can be fortified against cyber threats. The focus will be on how the architecture can be navigated and manipulated to maintain persistence on a host without detection, a critical skill for both offensive and defensive cyber operations.

Build Environments and Software Frameworks

Build environments are the unsung heroes of software development. This course offers an in-depth look at various build environments and software frameworks that are pivotal in developing Unix-based systems. We will cover how to customize and secure these environments, ensuring the integrity of the build process and the confidentiality of the codebase. Understanding these environments is key to creating software that can resist tampering and maintain its intended functionality in a hostile environment.

Linux Kernel

The Linux Kernel is at the heart of any Unix system, and mastering it is essential for any senior CNO developer. Our sessions will cover the kernel's role in managing system resources and enforcing security policies. Participants will learn to navigate kernel-level operations and manipulate kernel modules — skills necessary for developing software that interacts with system hardware in a secure and controlled manner, and for understanding the potential attack vectors that adversaries might exploit.

Processes

Processes are the lifeblood of a Unix system, and this course will teach you how to expertly manage and secure them. We will study process creation, execution, and monitoring, emphasizing how to manage these processes to ensure secure and efficient system operation. Understanding processes from a security standpoint allows for the design of software that can effectively hide from or resist adversary detection and termination.

Threads

Threads allow for concurrent operations within a process. In this part of the course, students will learn about thread synchronization, scheduling, and their implications on system stability and security. Mastery of threads is crucial for creating software that can efficiently execute multiple tasks in a secure manner, while also preventing race conditions and other concurrency-related security issues.

Memory Management

A deep understanding of memory management is essential for developing resilient software. We cover memory allocation, paging, segmentation, and how to protect against common vulnerabilities like buffer overflows and memory leaks. Memory management from a cybersecurity perspective is not just about efficient resource use but also about safeguarding against exploitation techniques used in advanced persistent threats.

Synchronous I/O Multiplexing

Input/Output (I/O) operations can be a system's Achilles' heel if not managed correctly. This course will cover the mechanisms of synchronous I/O multiplexing, allowing for the handling of multiple I/O streams. We will explore how to use these mechanisms to optimize performance and protect against I/O-based vulnerabilities, a common vector for denial-of-service attacks and other exploitations.

Executables

Understanding the creation and management of executables is paramount. We explore the anatomy of Unix executables, focusing on binary formats, linking, loading, and runtime execution. This knowledge is critical for reverse engineering and the development of software that must remain hidden or resilient against reverse engineering by adversaries.

Management Mechanisms

In this module, we cover the various management mechanisms inherent to Unix systems. We will explore how these mechanisms can be used to maintain system integrity and security, focusing on their application in secure software deployment and operation within contested cyber environments.

Network Programming

Network programming is the backbone of CNO development. This course includes an extensive examination of socket programming, protocol implementation, and network stack interaction. Participants will learn to develop network applications with a strong emphasis on security, enabling the creation of software that can communicate stealthily and resist network-based attacks.

Devices and Drivers

Interfacing with devices at the driver level is a powerful capability. Our curriculum includes in-depth coverage of Unix device management, driver development, and how these components interact with the rest of the system. Understanding device drivers is essential for the development of software that operates at the hardware level, a common requirement for sophisticated cyber operations.

Security Mechanisms

Unix systems come with an array of built-in security mechanisms. We dissect these mechanisms, such as permissions, access control lists, and user authentication features. Understanding and leveraging these mechanisms are crucial for developing software that can operate securely and persist on a system despite efforts to detect and remove unauthorized software.

File System Objects

The final piece of the puzzle is the file system, where all data ultimately resides. This course will cover the manipulation and management of file system objects, understanding how they can be used or misused by both developers and adversaries. We will look at securing data at rest, file system permissions, and how to develop software that interacts with the file system in a manner that is both effective and discreet.
