Core Information Security Concepts and Models

CIA Triad from a Data Protection Perspective

The CIA Triad is fundamental to data protection:

  • Confidentiality: Ensures data is protected from unauthorized disclosure.
  • Integrity: Ensures data is accurate and reliable.
  • Availability: Ensures data is accessible when and where it is needed.

Confidentiality Examples

  • Information Existence Confidentiality: E.g., juvenile records.
  • Information Confidentiality: E.g., encrypting a medical record database and granting access only with proper authorization.

Integrity

Operating System Concepts: C Code Implementations

1. Process Management and Inter-Process Communication (IPC)

1a. Process Creation using fork()

This program demonstrates the creation of a child process using the fork() system call and distinguishes between the parent and child processes.

#include <stdio.h>
#include <sys/types.h>
#include <unistd.h>

int main() {
    pid_t pid, mypid, myppid;

    pid = getpid();
    printf("Before fork: Process id is %d\n", pid);

    pid = fork();

Fundamentals of Soft Computing and Optimization

Definition of Multivariate Functions

A multivariate function is a function that has two or more independent variables. It assigns a single output value to each ordered set of input values.

Challenges in Non-Linear Optimization

  • Multiple Local Optima: Non-linear functions can have many local minima and maxima, making it difficult to find the global optimum.
  • Complex Behavior: The function may be curved, irregular, or non-convex, which makes analytical solutions

Key Concepts in Critical Social and Digital Theory

Essential Concepts in Critical Social and Digital Theory

Power, Discipline, and Surveillance

Panopticon

  • Author(s): Jeremy Bentham / Michel Foucault
  • Definition: A design for a circular prison in which all inmates can be observed by a single guard without knowing when they are being watched.
  • Expanded Explanation: The concept illustrates visibility as a method of social control; the uncertainty produces self-regulation.
  • Detailed Example (Exam-Ready): CCTV in public spaces makes people behave as though they

19th Century Spanish Wars: Peninsular and Carlist Conflicts

The Peninsular War (1807–1814)

The Peninsular War (1807–1814) was a military conflict fought by Bourbon Spain and Portugal, assisted by the United Kingdom, against the invading and occupying forces of the First French Empire for control of the Iberian Peninsula during the Napoleonic Wars. The war began when the French and Spanish armies invaded and occupied Portugal in 1807, and escalated in 1808 after Napoleonic France took over Spain, previously its ally, and installed Joseph Bonaparte on the

Maturation Concept and Environmental Influences on Development

Maturation Concept

The term maturation was not known before Arnold Gesell examined this concept, coined as a necessary predisposition for operating all existing systems. Gesell said that in the mature stage there are many maturities; these maturities are stages where the body reaches sensitivity to new stimuli. This concept is what all biologists have stated: ripening is an anatomic-physiological process that is genetically determined and characteristic of each species.

Experiments Based on Maturation

Iris Marion Young: Oppression, Justice, and Social Change

Iris Marion Young: Justice, Oppression, and Difference

Iris Marion Young (1949–2006) was a pioneering political theorist who significantly reshaped contemporary debates on justice by moving beyond a narrow focus on the distribution of goods to a deeper analysis of oppressive social structures and institutional power. She argued that injustice is embedded in everyday practices, norms, and decision-making processes rather than merely in unequal allocation of resources.
