🛡️ Online Security
Cybersecurity, also known as digital security, includes all measures taken to protect information—such as accounts, files, and images—through strategies and defense actions for computers, mobile devices, servers, networks, and electronic systems, with the goal of preventing cyberattacks and data breaches.
In recent years, the rise in cyber threats has made it clear: advanced security measures are essential to protect a company’s digital assets.
But what exactly does cybersecurity mean? What are its key features, and how can we protect our data?

🛡️ Three Core Principles of Cybersecurity (CIA Triad)
Every cybersecurity strategy is built on three fundamental principles:
1️⃣ Availability: Ensuring Access to Data
Availability ensures that information is accessible to authorized users whenever needed.
🔷 Why is it important?
Maintains business continuity
Prevents service interruptions and ensures a smooth user experience
Reduces productivity loss caused by system or data downtime
🔧 How to ensure it?
✔ Regular backups to prevent data loss
✔ Redundant systems to avoid outages from hardware failures
✔ Disaster recovery plans to restore data in emergencies
2️⃣ Integrity: Ensuring Data Accuracy
Integrity ensures that data is not altered, corrupted, or deleted without authorization.
🔷 Why is it important?
Supports accurate and reliable decision-making
Prevents data manipulation and fraud
Avoids legal penalties due to non-compliance (e.g., GDPR)
🔧 How to ensure it?
✔ Hashing techniques to verify file integrity
✔ Version control to track changes
✔ Regular backups to recover original data if corruption occurs
3️⃣ Confidentiality: Protecting Sensitive Information
Confidentiality ensures that only authorized individuals can access sensitive information.
🔷 Why is it important?
Safeguards the privacy of individuals and organizations
Prevents leaks of confidential data that could harm reputation
Reduces the risk of financial fraud and identity theft
🔧 How to ensure it?
✔ Encryption to make data unreadable without authorization
✔ Multi-factor authentication (MFA) for secure access
✔ Role-based access control and permission management
