Network Security Engineer Quiz Total 10 Questions Please enter your email: 1. What best practices should be followed when deploying ‘Internet of Things’ (IoT) devices on corporate networks to maintain security? Connect IoT devices directly to the internet to isolate them from the corporate network 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 2. Considering recent advancements in ‘quantum computing’, how should network security strategies evolve to address potential future cryptographic challenges? Focus solely on physical security measures as they remain unaffected by quantum computing Discontinue the use of encryption as it will become obsolete with quantum computing Quantum computing poses no real threat to current encryption methods; no changes needed Adopt quantum-resistant cryptographic algorithms and plan for quantum-safe encryption methods 3. What factors should be considered when choosing between ‘on-premises’ vs ‘cloud-based’ network security solutions? Security needs, compliance, scalability, cost, control over data, and management capabilities The decision should be based solely on the cost of implementation Cloud-based solutions are always superior; no need to consider on-premises Choose based on the preference of the organization’s executive team 4. How does ‘Secure Socket Layer’ (SSL) and ‘Transport Layer Security’ (TLS) enhance web security? By encrypting data transmissions between browsers and servers They scan and filter malicious content from web traffic By increasing the speed of web page loading SSL and TLS are outdated protocols that have been replaced by IPSec 5. What security vulnerabilities are introduced by ‘Internet of Things’ (IoT) devices, and how can they be mitigated? IoT devices are inherently secure and introduce no new vulnerabilities Vulnerabilities are primarily due to increased network traffic, mitigated by bandwidth upgrades Weak configurations and insecure data transmission; mitigated with strong authentication and updates Mitigation is not possible due to the diverse nature of IoT devices 6. What is the significance of ‘port scanning’ in network security assessments? Port scanning has no significance in modern network security practices It is a method to increase the speed of network connections Identifies open ports and potential vulnerabilities Used to physically secure ports against unauthorized access 7. How do ‘Intrusion Detection Systems’ (IDS) differ from ‘Intrusion Prevention Systems’ (IPS)? IDS only alert on threats; IPS actively block them IPS are used exclusively for detecting malware; IDS are not IDS encrypt data; IPS do not There is no significant difference; the terms are used interchangeably 8. How does implementing a Zero Trust security model alter traditional network security practices? It relies on traditional perimeter defenses and strengthens them It decreases security complexity by trusting all devices within the network Zero Trust only applies to external threats, not internal network transactions Requires verification for every access request, eliminating implicit trust 9. What is ‘phishing’ and how can network security measures counteract it? Using email filtering and DMARC policies to authenticate emails Increasing network bandwidth to handle phishing attacks By physically securing network infrastructure Phishing attacks cannot be counteracted by network security measures 10. 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 Launch DDoS attacks and spread malware; mitigated with endpoint protection and monitoring Botnets improve network security by distributing computational tasks They only affect standalone computers, not networked devices Loading … Question 1 of 10
