E-commerce Security Requirements

E-commerce security refers to the protection of e-commerce assets from unauthorized access, use, alteration, or destruction. Because financial transactions and sensitive information (like credit card numbers, passwords, and personal details) are involved, strong security is essential in e-commerce systems.

Key E-commerce Security Requirements:

• Authentication: Ensures that the parties involved (both buyer and seller) are who they claim to be.
• Authorization: Grants specific permissions to authenticated users.
• Confidentiality: Ensures that data is accessible only to authorized individuals.
• Integrity: Ensures that data is not altered during transmission or storage.
• Non-Repudiation: Prevents parties from denying their actions.

Why MIS is the Most Important Business Class

Why is the introduction to Management Information Systems (MIS) the most important class in business school? Consider these fundamental laws of technology:

• Bell's Law: Electronic devices become smaller over the years.
• Moore's Law: The price per 100,000 transistors becomes lower over the years (Pic2).

MIS Job Demand and Security

Why are MIS-related jobs in high demand? They have been the fastest-growing jobs over the past 20 years, as product and service innovation is made easier through technology. MIS affects everyone because technological change is accelerating. For example, Bell's Law impacts businesses; a company could go bankrupt quickly...

Convolutional Neural Networks: Concepts & Applications

A Convolutional Neural Network (CNN) is a deep learning algorithm primarily used for image-related tasks. It automatically and adaptively learns spatial hierarchies of features from input images, making it highly effective for visual data processing.

Key Components of a CNN

• Convolutional Layer: Applies filters to extract features such as edges, textures, and patterns.
• Activation Function (ReLU): Introduces non-linearity into the model, allowing it to learn complex relationships.
• Pooling Layer: Reduces the spatial dimensions (width and height) of the feature maps, retaining essential information and reducing computational load.
• Fully Connected Layer: Makes final predictions based on the high-
