- Cybersecurity: Phishing, Malware, and Encryption
- Description
Cybersecurity Basics
Cybersecurity involves protecting computer systems, networks, and data from digital attacks, unauthorized access, and damage.
Key Threats
- Phishing: Fraudulent emails or messages designed to trick users into revealing sensitive information, such as passwords or credit card numbers.
- Malware: Malicious software including viruses, worms, spyware, and trojans designed to disrupt, damage, or gain unauthorized access.
- Ransomware: A type of malware that encrypts files and demands payment (ransom) for the decryption key.
- DDoS (Distributed Denial of Service): An attack that overwhelms a server, service, or network with a flood of internet traffic to make it unavailable.
Protection & Mitigation
- Encryption: Translates plain text into cipher text using mathematical algorithms (e.g., AES, RSA), ensuring only authorized parties with the decryption key can read it.
- Two-Factor Authentication (2FA): Adds an extra layer of security by requiring two distinct forms of identification before access is granted.
- Firewall: A security device or software that monitors and filters incoming and outgoing network traffic based on established security rules.
- VPN (Virtual Private Network): Establishes a secure, encrypted tunnel over the internet to protect user privacy and data transmission.
