Introduction to Cybersecurity

Cybersecurity is the practice of protecting systems, networks, and data from digital attacks. As cyber threats continue to evolve, understanding cybersecurity fundamentals is crucial for safeguarding information and ensuring system integrity.

Key Concepts

• Confidentiality, Integrity, and Availability (CIA Triad)
  The CIA Triad is the foundation of cybersecurity:

  • Confidentiality: Ensures that information is accessible only to authorized individuals.
  • Integrity: Maintains the accuracy and completeness of data.
  • Availability: Ensures that information and resources are available to authorized users when needed.

• Common Threats
  Cyber threats include malware, phishing, ransomware, and social engineering attacks. Understanding these threats helps in designing defenses and developing a proactive approach to security.

• Vulnerability and Risk Management
  Vulnerabilities are weaknesses in systems, while risks are the potential for those vulnerabilities to be exploited. Effective cybersecurity involves identifying, assessing, and mitigating risks.

• Firewalls and Intrusion Detection Systems (IDS)
  Firewalls control incoming and outgoing network traffic, while IDS monitors network activity for signs of potential security breaches. Both are critical for defending against unauthorized access.

• Encryption and Cryptography
  Encryption secures data by converting it into unreadable formats without the correct key. Cryptography underpins secure communication, protecting data both at rest and in transit.

Why Cybersecurity Matters

With the rise in cyber threats, cybersecurity has become essential for protecting personal information, business assets, and national infrastructure. Knowledge of cybersecurity is crucial for everyone in tech, from developers to network administrators.
