Network Security and Virtualization Quiz

What are physical controls in network security?

• Measures taken to protect the physical infrastructure of a network.

• Intrusion detection systems

• Encryption algorithms

• Software firewalls

Give an example of a physical control used in network security.

• encryption

• antivirus software

• mantrap

• intrusion detection system

What are technical controls in network security?

• Measures implemented in hardware or software to protect the network infrastructure and data.

• Techniques used to encrypt network traffic

• Procedures and policies implemented to protect network resources

• Methods used to secure physical access to the network

Name a common technical control used to protect network data.

• security guard

• Intrusion detection system

• cameras

• alarms

What is virtualization?

• The process of creating a virtual version of something.

• The process of creating a physical version of something.

• The process of creating a digital version of something.

• The process of creating a virtual reality experience.

How does virtualization help in cloud computing?

• Virtualization allows multiple virtual machines to run on a single physical server.

• Virtualization increases the cost of hardware in cloud computing.

• Virtualization disables scalability in cloud computing.

• Virtualization weakens network security in cloud computing.

What are the benefits of using physical controls in network security?

• Physical controls in network security provide several benefits such as preventing unauthorized physical access to network devices, protecting against physical theft or damage, and ensuring the physical integrity of network infrastructure.

• Detecting and mitigating network attacks

• Enhancing network speed and performance

• Improving network scalability and flexibility

What are the disadvantages of relying solely on physical controls for network security?

• Physical controls can be easily bypassed or tampered with, do not protect against virtual threats, and can be costly to implement and maintain.

• Physical controls may not be scalable for large networks

• Physical controls can limit flexibility and mobility for users

• Physical controls are only effective against sophisticated cyber attacks

What are the different types of technical controls used in network security?

• Onboarding procedures, Exit policy, TTL, SMTP

• Operating system, overclocking, cable management

• password policies, camera monitoring, key-logging

• Access controls, Firewalls, IDS/IPS, VPNs, Network Segmentation, Encryption, Antivirus/Antimalware Software, Patch Management

Explain the concept of firewall in network security.

• A firewall is a physical barrier that prevents unauthorized access to a network.

• A firewall is a software program that protects a computer from viruses and malware.

• A firewall is a device that encrypts all network traffic to ensure secure communication.

• A firewall is a network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules.
