Cybersecurity Training: Introduction

Cybersecurity Fundamentals

Welcome to this introductory cybersecurity training. We will explore the fundamental concepts to protect your data and systems from online threats.

  • Confidentiality: Ensuring that information is accessible only to authorized individuals.
  • Integrity: Maintaining the accuracy and completeness of data.
  • Availability: Guaranteeing that systems and data are accessible when needed.

Firewall

A firewall is a security barrier that controls incoming and outgoing network traffic, blocking unauthorized access.

Types of Firewalls:

  1. Hardware Firewalls
  2. Software Firewalls

VPN (Virtual Private Network)

A VPN creates a secure, encrypted connection between your device and a remote server, masking your IP address and protecting your data when using public Wi-Fi networks.

  • Use strong and unique passwords.
  • Enable two-factor authentication (2FA) when possible.
  • Regularly update your software and operating systems.
