Answer: A firewall is a security device that monitors and controls incoming and outgoing network traffic based on predetermined rules. You use it to create a barrier between trusted internal networks and untrusted external networks. Firewalls prevent unauthorised access and block malicious traffic. They are essential for protecting network infrastructure.

6) Can you describe a phishing attack?

Answer: Phishing is a cyber-attack where attackers masquerade as legitimate entities to trick you into revealing sensitive information. You may receive fake emails or messages that appear genuine, urging you to click on malicious links or provide personal details. Recognising these tactics is crucial to avoid falling victim to phishing. Educating users about these threats is an essential preventive measure.

7) How can you create a strong password?

Answer: Creating a strong password requires a mix of upper- and lower-case letters, numbers, and special characters. It should be at least 12 characters long and avoid easily guessable information like birthdays. Regularly updating passwords and using unique ones for different accounts enhances security. Implementing multi-factor authentication adds an extra layer of protection.

8) What steps would you take if you detected a security breach?

Answer: First, you would contain the breach to prevent further damage. Next, you would identify and assess the extent of the breach, gathering relevant data. You would then work on eradicating the threat and restoring affected systems. Finally, you would analyse the breach to improve security measures and prevent future incidents.

9) How do you handle sensitive data?

Answer: You can simply handle sensitive data with utmost care, ensuring it is encrypted and stored securely. Access to sensitive data is restricted to authorised personnel only. Regular audits and monitoring help detect any unauthorised access or anomalies. You also educate users on best practices for handling sensitive information.

10) What is a vulnerability assessment?

Answer: A vulnerability assessment identifies, quantifies, and prioritises security vulnerabilities in a system. Various tools and techniques can be used to scan for weaknesses. The goal is to address these vulnerabilities before attackers can exploit them. Regular assessments help maintain a robust security posture.

11) Can you explain the concept of multi-factor authentication (MFA)?

Answer: MFA is a security system that requires multiple forms of verification before granting access to an account or system. You can typically use something you know (password), something you have (security token), and something you are (fingerprint) as factors. By adding extra layers of security, MFA significantly reduces the risk of unauthorised access

.

12) What is social engineering, and how can you prevent it?

Answer: Social engineering involves manipulating people into divulging confidential information. You prevent it by educating users about common tactics like phishing, pretexting, and baiting. Encouraging scepticism and verifying the identity of requesters helps. Implementing security protocols and monitoring suspicious activities also mitigate social engineering risks.
