Network Security Engineer Quiz Total 10 Questions Please enter your email: 1. Which protocol is used for securely accessing remote servers, replacing Telnet? FTP SNMP HTTP SSH 2. What challenges do ‘encrypted threats’ pose to traditional network security measures, and how can they be countered? Can only be countered by completely disabling encryption on the network They make network traffic slower and easier to intercept Bypass traditional measures; countered with encrypted traffic inspection and advanced detection Encrypted threats are less dangerous than unencrypted threats and require no special attention 3. What are the security implications of ‘cloud-based networking’ for businesses, and how can they ensure protection? The main implication is increased network speed, not security concerns Concerns over data privacy and access; protection involves encryption and robust access controls Cloud-based networking is inherently secure and requires no additional protection measures Businesses can ensure protection by avoiding cloud-based solutions altogether 4. What is ‘Deep Packet Inspection’ (DPI) and its significance in network security? A firewall configuration option for external networks A technique for physically inspecting network cables A method for increasing network speed Inspects data packets in detail to identify and stop threats 5. How do ‘Botnet attacks’ threaten network security, and what strategies can mitigate their impact? The best strategy is to isolate the network from the internet Botnets improve network security by distributing computational tasks They only affect standalone computers, not networked devices Launch DDoS attacks and spread malware; mitigated with endpoint protection and monitoring 6. A critical server is repeatedly infected with malware despite having up-to-date antivirus software. What additional security measures could prevent future infections? Limit the server’s functionality to reduce the risk of infection Application whitelisting, DMZ isolation, update firewall rules, and conduct security audits Disconnect the server from the network permanently as a preventative measure Replace the antivirus software with a different brand and hope for better results 7. What best practices should be followed when deploying ‘Internet of Things’ (IoT) devices on corporate networks to maintain security? IoT devices should not be used on corporate networks due to inherent security flaws Use reputable devices, change passwords, update firmware, segregate on VLANs, monitor traffic Use a single standard IoT protocol across all devices for simplicity and security Connect IoT devices directly to the internet to isolate them from the corporate network 8. In a security review, you find that network encryption protocols are outdated. Upgrading them could disrupt service. How do you approach this upgrade? Ignore the issue until the next scheduled upgrade cycle to avoid disruption Use both old and new protocols simultaneously to avoid any disruption Immediately upgrade without testing to ensure the highest level of security Plan for a low-traffic period, communicate downtime, and test in staging first 9. What does a ‘Demilitarized Zone’ (DMZ) in network architecture refer to? A secure network for storing sensitive information A network exclusively for military use A network setup to trap attackers with fake data A subnetwork that exposes external-facing services to the internet 10. How are ‘virtual private networks’ (VPNs) used to secure remote access to a network? They allow remote access without encryption to maximize speed By creating a secure, encrypted tunnel for data transmission VPNs detect and eliminate malware from remote access attempts VPNs are not used for securing remote access; they are for anonymizing internet traffic Loading … Question 1 of 10
