Study Notes

Introduction to Cybersecurity

  • Cybersecurity encompasses the technologies, processes, and practices designed to protect computer systems, networks, and data from unauthorized access, use, disclosure, disruption, modification, or destruction.
  • It's a critical concern in today's digital age, with increasing reliance on technology across various sectors.
  • The goal of cybersecurity is to safeguard sensitive information, maintain system availability, and ensure business continuity.

Types of Cyber Threats

  • Malware: Malicious software designed to damage or disable computer systems. Examples include viruses, worms, Trojans, ransomware, spyware.
  • Phishing: A social engineering technique used to deceive individuals into revealing sensitive information, often through fraudulent emails or websites.
  • Denial-of-Service (DoS) attacks: Attempts to make a machine or network resource unavailable to the intended users, typically by overwhelming it with traffic.
  • Man-in-the-middle (MitM) attacks: An attacker intercepts and relays communication between two parties without their knowledge.
  • SQL Injection: Exploiting vulnerabilities in applications that use SQL databases to run malicious code and gain unauthorized access.
  • Insider Threats: Employees or contractors who intentionally or unintentionally compromise security.
  • Zero-Day Exploits: Attacks based on vulnerabilities that are unknown to the software vendor.
