Data Science is an interdisciplinary field that uses data, statistics, mathematics, programming, and domain knowledge to extract meaningful insights from structured and unstructured data.
Its goal is to support decision-making, predict outcomes, identify patterns, and solve real-world problems.
Gathering data from databases, APIs, sensors, surveys, logs, etc.
Handling missing values, removing duplicates, correcting errors.
Exploring data to understand patterns and trends.
Applying statistical or machine learning models.
Presenting insights using charts, dashboards, and reports.
Using insights to guide business or operational actions.
At the heart of cybersecurity lies the CIA Triad, which represents three fundamental security principles:
Used to understand data behavior and relationships.
Example: Understanding customer spending behavior using averages and trends.
Focus on discovering patterns in large datasets.
Example: Finding products frequently bought together on an e-commerce site.
Enable systems to learn from data without explicit programming.
Example: Predicting house prices or customer churn.
Example: Segmenting customers based on behavior.
Example: Recommendation systems, robotics.
Uses historical data to forecast future outcomes.
Example: Sales forecasting, demand prediction.
Handle massive volumes of data.
Example: Processing social media or IoT data.
Deals with text and speech data.
Example: Analyzing customer feedback or social media sentiment.
Help in understanding and communicating insights.
Example: Executive dashboards for decision-makers.
