FOUNDATIONS — (OPERATING SYSTEM FUNDAMENTALS) (WHAT IS AN OPERATING SYSTEM AND HOW IT WORKS) Every attack, every defense, every tool you will ever use runs on top of an operating system. If you do not understand how it works internally, you are operating blind. The OS is not just a background process — it is the environment that controls everything. Understanding its structure tells you exactly where control can be gained or lost. (KERNEL — THE CORE CONCEPT) The kernel is the most privileged layer of any operating system. It has direct access to hardware, memory, and every process running on the system. This is why the most dangerous attacks target kernel level. A compromise here means total control of the machine. Understanding the kernel is not advanced knowledge — it is foundational. (USER MODE VS KERNEL MODE) These two modes define the boundary between normal operations and privileged system access. Most attacks attempt to cross this boundary. Understanding why this separation exists and how it is enforced tells you exactly how privilege escalation works and why it is one of the most critical concepts in system security. (PROCESS AND THREAD CONCEPTS) Every program running on your system is a process. Every task within that program is a thread. Malicious software hides inside legitimate processes. It injects threads into trusted applications. Without understanding how processes and threads work, you cannot detect what should not be there. (FILE SYSTEM STRUCTURES — NTFS, EXT4, FAT32) File systems are not just storage organization. They determine how data is written, how permissions are enforced, how deletion works, and critically — what traces are left behind. NTFS stores metadata that tells the full story of file activity. ext4 behaves differently under forensic analysis. FAT32 has structural weaknesses that matter in certain attack scenarios. Knowing the difference is essential. (MEMORY MANAGEMENT) The operating system controls how memory is allocated, used, and released. Buffer overflows, memory corruption, and certain injection techniques all exploit weaknesses in memory management. This is not theoretical — these are real attack categories that require memory knowledge to understand and defend against. (SYSTEM CALLS) System calls are the bridge between user applications and the kernel. Every time software needs to access hardware, read a file, or open a network connection — it goes through a system call. Monitoring system calls is one of the most powerful methods of detecting malicious behavior on a live system. You cannot monitor what you do not understand. The operating system is the environment where everything happens. Master this layer and the entire field starts to make sense. Part 3 is coming. Follow to stay on track. 👇🔐 #cybersecurity #OperatingSystemSecurity #CyberAwareness #DigitalDefense #SecurityMindset​​​​​​​​​​​​​​​​
