Session 3: FAQs and Related Articles
FAQs:
1. What is the difference between symmetric and asymmetric encryption? Symmetric uses the same key for encryption and decryption, while asymmetric uses separate public and private keys.
2. What is a firewall, and how does it protect a network? A firewall acts as a barrier, controlling network traffic based on predefined rules, blocking unauthorized access.
3. What are the key components of a strong password? Length, complexity (combination of uppercase, lowercase, numbers, and symbols), and uniqueness.
4. How does phishing differ from other types of cyberattacks? Phishing uses deceptive tactics to trick users into revealing sensitive information.
5. What is the importance of regular software updates? Updates patch vulnerabilities that attackers could exploit, improving security.
6. What is the role of risk assessment in cybersecurity? It identifies potential threats and vulnerabilities, allowing organizations to prioritize mitigation efforts.
7. How does multi-factor authentication enhance security? It adds an extra layer of security by requiring multiple forms of authentication, making it harder for attackers to gain access.
8. What are some common types of malware? Viruses, worms, Trojans, ransomware, spyware, and adware.
9. What is the significance of data backups in a comprehensive security strategy? Backups provide a recovery mechanism in case of data loss due to cyberattacks or other incidents.
