VIRTUALIZATION ESSENTIALS FOR CYBER SECURITY

What is a hypervisor and how does it contribute to cyber security?

• A hypervisor is a type of antivirus software that protects against cyber attacks.

• A hypervisor is a physical hardware component that enhances cyber security by encrypting data transmissions.

• A hypervisor is a software that creates and runs virtual machines on a physical host machine. It contributes to cybersecurity by providing isolation between virtual machines, preventing malware from spreading across different VMs, and allowing for secure testing and analysis of potentially harmful software.

• A hypervisor is a network protocol used to secure virtual machines from external threats.

Explain the concept of containerization in the context of security.

• Containerization is a method of encrypting data within containers to enhance security.

• Containerization in the context of security involves packaging applications and dependencies into containers for consistent and isolated execution, reducing the attack surface and simplifying security management.

• Containerization involves breaking down security barriers between applications.

• Containerization is the process of storing containers in a secure vault for protection.

How does network virtualization enhance cyber security measures?

• Network virtualization enhances cyber security measures by reducing the visibility of network traffic

• Network virtualization enhances cyber security measures by slowing down network performance

• Network virtualization enhances cyber security measures by increasing vulnerability to cyber attacks

• Network virtualization enhances cyber security measures by providing a secure and isolated environment for testing security protocols, enabling easier monitoring and management of network traffic, and facilitating the implementation of access controls and segmentation.

What are the key benefits of using virtual machine management tools for cyber security?

• Increased vulnerability to cyber attacks

• Limited scalability of security measures

• Inefficient resource allocation for security tasks

• Isolation of environments, easy deployment of security updates, centralized management of security configurations, and controlled testing environments.

Name two popular hypervisor technologies used in the industry.

• Citrix XenServer

• Oracle VirtualBox

• VMware vSphere, Microsoft Hyper-V

• KVM

Discuss the security implications of containerization compared to traditional virtualization.

• Containerization provides better security due to isolated environments

• Traditional virtualization is faster and more resource-efficient

• Containerization offers separate OS instances for each container

• Containerization is faster and more resource-efficient but can pose security risks due to shared kernel, while traditional virtualization offers better isolation and security by providing separate OS instances for each VM.

What role does network virtualization play in securing data transmission within a virtual environment?

• Network virtualization enhances data transmission speed within a virtual environment.

• Network virtualization increases data vulnerability within a virtual environment.

• Network virtualization creates isolated virtual networks with security policies, segmentation, and encryption to secure data transmission within a virtual environment.

• Network virtualization reduces the need for data encryption in a virtual environment.

How can virtual machine management tools help in detecting and mitigating security threats?

• Virtual machine management tools provide entertainment features instead of security monitoring

• Virtual machine management tools offer real-time monitoring, vulnerability scanning, intrusion detection, and automated response mechanisms to detect and mitigate security threats.

• Virtual machine management tools rely on outdated databases for threat detection

• Virtual machine management tools only focus on hardware optimization and ignore security threats

What are the differences between Type 1 and Type 2 hypervisors?

• Type 1 hypervisors are designed for personal use, while Type 2 hypervisors are for enterprise environments.

• Type 1 hypervisors require a network connection, while Type 2 hypervisors do not.

• Type 1 hypervisors run directly on the host's hardware, while Type 2 hypervisors run on a conventional operating system.

• Type 1 hypervisors are free to use, while Type 2 hypervisors require a license.

Explain how containerization isolates applications for improved security.

• Containerization isolates applications by running them in the same environment as the host OS, compromising security.

• Containerization isolates applications by sharing all dependencies with the host system, reducing security measures.

• Containerization isolates applications by encapsulating them along with their dependencies into a container, which runs independently from the host system. This isolation prevents direct interaction with the host OS, enhancing security.

• Containerization isolates applications by exposing them directly to the host OS, increasing security risks.
