Network Security Engineer Quiz Total 10 Questions Please enter your email: 1. What role does ‘Endpoint Detection and Response’ (EDR) play in a comprehensive network security strategy? EDR technologies are outdated and replaced by newer security solutions EDR is solely focused on enhancing network speed and efficiency It’s used for data loss prevention only, not threat detection Monitors endpoints to detect, investigate, and respond to threats 2. During a routine network audit, you discover an unauthorized device connected to the network. What steps should you take to address this security breach? Ignore the device until the audit is completed to maintain audit integrity Increase network bandwidth to dilute the impact of the unauthorized device Disconnect the internet to the entire network to prevent data exfiltration Isolate the device, investigate the breach, and strengthen access controls 3. How does implementing a Zero Trust security model alter traditional network security practices? Zero Trust only applies to external threats, not internal network transactions It relies on traditional perimeter defenses and strengthens them Requires verification for every access request, eliminating implicit trust It decreases security complexity by trusting all devices within the network 4. How does ‘Secure Socket Layer’ (SSL) and ‘Transport Layer Security’ (TLS) enhance web security? They scan and filter malicious content from web traffic SSL and TLS are outdated protocols that have been replaced by IPSec By encrypting data transmissions between browsers and servers By increasing the speed of web page loading 5. 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 Used to physically secure ports against unauthorized access Identifies open ports and potential vulnerabilities 6. What strategies can be employed to secure a network against ‘Shadow IT’ risks? Ignoring Shadow IT risks as they are considered minimal Blocking all external internet access to prevent unauthorized device usage Allowing Shadow IT but monitoring it for malicious activity Conducting audits, implementing IT policies, educating employees, and providing alternatives 7. What is the function of ‘Network Access Control’ (NAC) in securing a network? To restrict network access to compliant devices To physically secure network servers and equipment To encrypt network communications To prioritize network traffic 8. Describe how ‘machine learning’ can enhance network security monitoring and threat detection. Machine learning increases the risk of false positives in threat detection, hindering security efforts Machine learning makes network security monitoring obsolete by automating all protections It is primarily used to reduce the workload on security teams, with no improvement in threat detection Analyzes network data to identify patterns and anomalies, improving threat detection accuracy 9. What role do ‘security policies’ play in a network security framework? Define rules and procedures for protecting resources They dictate the physical layout of network infrastructure Primarily focus on optimizing network performance Are only relevant for documenting security incidents 10. How can ‘security automation’ tools reduce the risk of human error in network security operations? Perform repetitive tasks and respond to threats faster, reducing human error By completely removing the need for human involvement in security operations They increase human error by making security teams complacent Automation tools are prone to errors; relying on them increases risk Loading … Question 1 of 10
