Essential Cybersecurity Terms

  • Authentication: The process of verifying a user’s identity before granting access to a system or data. Common methods include passwords, multi-factor authentication (MFA), and biometrics.

  • Authorization: Determining what level of access a user has once they are authenticated. This controls what actions a user can perform within a system.

  • Black Hat Hacker: A hacker who exploits computer systems or networks for malicious purposes, such as stealing data or disrupting operations.

  • Botnet: A network of compromised devices controlled by a single attacker. Botnets are often used to launch Distributed Denial-of-Service (DDoS) attacks.

  • Data Breach: An unauthorized access or disclosure of sensitive data, such as personal information or financial records.

  • Encryption: The process of scrambling data using a key or algorithm to make it unreadable by unauthorized users. Encryption protects data at rest (stored) and in transit (being transmitted).

  • Firewall: A security system that monitors incoming and outgoing network traffic, filtering out malicious activity and protecting internal systems.

  • Malware: Malicious software designed to harm a computer system or network. Examples include viruses, worms, ransomware, and spyware.

  • Multi-Factor Authentication (MFA): An additional layer of security beyond just a password. MFA requires a second verification step, such as a code sent to your phone or a fingerprint scan.

  • Phishing: A deceptive email or message designed to trick the recipient into clicking a malicious link or revealing personal information.

  • Ransomware: A type of malware that encrypts a victim’s files, demanding a ransom payment to decrypt them.

  • Social Engineering: The manipulation of people into divulging sensitive information or performing actions that compromise their security.

  • Vulnerability: A weakness in a computer system or network that can be exploited by attackers.
