Session 3: FAQs and Related Articles
FAQs:
1. What is the difference between a virus and a worm? A virus requires a host program to infect, while a worm can replicate independently.
2. How can I protect myself from phishing attacks? Verify email addresses, URLs, and look for suspicious grammar or requests for personal information.
3. What is multi-factor authentication, and why is it important? It adds an extra layer of security by requiring multiple forms of authentication (password, code from a phone app, etc.).
4. What is a VPN, and how does it enhance my online security? A VPN encrypts your internet traffic and masks your IP address, protecting your privacy and anonymity.
5. How often should I update my software and operating system? Regularly updating your systems patches security vulnerabilities.
6. What are the best practices for creating strong passwords? Use a password manager, combine uppercase and lowercase letters, numbers, and symbols.
7. What should I do if I suspect my computer has been infected with malware? Disconnect from the internet and run a full scan with your antivirus software.
8. What is ransomware, and how can I protect myself from it? Ransomware encrypts your files and demands a ransom. Regular backups and caution with email attachments are key.
9. How can I improve my overall online security awareness? Stay informed about emerging threats, practice caution when clicking links or downloading files, and be wary of unsolicited communications.
