Types of Cyber Threats

  • Malware: Malicious software designed to harm systems or steal data.
  • Phishing: Fraudulent attempts to obtain sensitive information via email.
  • Ransomware: Encrypts data and demands payment for decryption.
  • DDoS attacks: Overwhelm systems with traffic to disrupt services.

Importance of Strong Passwords

  • Weak passwords are responsible for 80% of data breaches.
  • Use at least 12 characters with a mix of letters, numbers, and symbols.
  • Password managers help create and store complex passwords securely.
  • Enable multi-factor authentication for added protection.

Network Security Measures

  • Firewalls act as barriers between trusted and untrusted networks.
  • VPNs encrypt internet connections for secure remote access.
  • Regularly update software to patch security vulnerabilities.
  • Network segmentation limits access to sensitive data.

Data Encryption Basics

  • Encryption converts data into unreadable code for protection.
  • End-to-end encryption ensures only sender and receiver can read messages.
  • AES-256 is the gold standard for encryption algorithms.
  • Encrypt sensitive data both at rest and in transit.

Social Engineering Risks

  • 98% of cyberattacks rely on social engineering tactics.
  • Attackers manipulate human psychology to gain access.
  • Common techniques include pretexting and baiting.
  • Security awareness training reduces vulnerability.
