What is OpenVPN used for?

The OpenVPN Community Edition (CE) is an open source Virtual Private Network (VPN) project. It creates secure connections over the Internet using a custom security protocol that utilizes SSL/TLS. This community-supported OSS (Open Source Software) project, using a GPL license, is supported by many OpenVPN Inc.

Which choice is a good reason to segment a network?

One of the primary reasons to segment a LAN is to increase the available bandwidth by reducing network congestion. Traffic over a business LAN tends to become isolated in certain areas.

Which network device can isolate broadcast traffic to the local network segment?

Thus routers have many segments and many collision domains. The routers can separate broadcast domains unlike switches that create separate collision domains but same broadcast domains. By default, routers break the broadcast domains and keep all devices separate on a segment from other segments.

What are some of the different reasons to use VLANs?

3.0 Why use VLAN's?

  • 1) Performance. In networks where traffic consists of a high percentage of broadcasts and multicasts, VLAN's can reduce the need to send such traffic to unnecessary destinations. …
  • 2) Formation of Virtual Workgroups. …
  • 3) Simplified Administration. …
  • 4) Reduced Cost. …
  • 5) Security.

Which two practices would you follow to prevent VLAN attacks on a network?

Which two practices would you follow to prevent VLAN attacks on a network? (Choose two.) Disable DTP on all ports. Change the default VLAN settings.

In which of the cloud service model virtualization concept is utilized?

In an IaaS service model, a cloud provider hosts the infrastructure components that are traditionally present in an on-premises data center. This includes servers, storage and networking hardware, as well as the virtualization or hypervisor layer.

Which cloud computing service would be best for an organization that needs to collaboratively create applications and deliver them over the web?

Which Cloud computing service would be best for an organization that needs to collaboratively create applications and deliver them over the web? Platform as a Service (PaaS) provides a collaborative environment where multiple developers can create software and host an application through a Cloud provider.

How public and private keys work in SSH?

Public And Private Key Uses An SSH key relies upon the use of two related keys, a public key and a private key, that together create a key pair that is used as the secure access credential. The private key is secret, known only to the user, and should be encrypted and stored safely.

Is it safe to share public SSH key?

Since it's a public key it isn't meant to be encrypted, it only allows to authentify your private key (which should never be shared publicly) so yes you can send it via email.

Which secure Tunnelling protocol might be able to cross firewalls where IPsec is blocked?

Which secured tunneling protocol might be able to cross firewalls where IPsec is blocked? – OpenVPN, is an open-source VPN protocol that uses a custom security protocol called OpenSSL for encryption. OpenVPN has the ability to cross many firewalls where IPsec might be blocked.

Which VPN is firewall friendly?

OpenVPN. OpenVPN is very firewall-friendly. Since it uses a single UDP or TCP port and is not affected by common NAT functions such as rewriting of source ports, it is rare to find a firewall which will not work with OpenVPN. The only possible difficulty is if the protocol and port in use is blocked.

At what layer of the OSI model does the IPsec encryption protocol operate?

The IPsec protocol suite operates at the network layer of the OSI model. It runs directly on top of IP (the Internet Protocol), which is responsible for routing data packets. Meanwhile, SSL operates at the application layer of the OSI model.

Should I use OpenVPN?

The main reason to use the OpenVPN protocol is because it's very secure, really stable, and it works on multiple platforms. Most security experts recommend always using OpenVPN for anything you do online – especially since it's such a transparent option (due to it being open-source).

Is OpenVPN good?

Is OpenVPN Safe? In short: yes. OpenVPN is generally the most secure protocol you can find and comes highly recommended by our experts. Audits of the protocol's security found only minor issues, which OpenVPN quickly resolved.

Why should I segment my network?

Network segmentation can boost your overall security policy by limiting access privileges to those who need it, protecting the network from widespread cyberattacks and enabling better network performance by reducing the number of users in specific zones.

Why do we need network segmentation?

By segmenting networks, it becomes easier to protect the most sensitive data that you have on your internally-facing network assets. The creation of a layer of separation between servers containing sensitive data and everything outside of your network can do wonders to reduce your risk of data loss or theft.

Which of the following is the best choice to segment traffic on a network?

Switches provide the easiest and most common way to segment traffic. Switches and bridges behave similarly; both devices accept traffic on any of their ports, examine each packet for destination information, and transmit the packet only to the port on which the target device resides.

Which network device is used to separate broadcast domains?

Answer – B – A router is used to break up broadcast domains. Key Takeaway: A broadcast domain is a logical division of a computer network in which all nodes can reach each other by broadcast at the data link layer.

What is a VLAN and for what purposes is IT used?

VLAN is a custom network which is created from one or more local area networks. It enables a group of devices available in multiple networks to be combined into one logical network. The result becomes a virtual LAN that is administered like a physical LAN. The full form of VLAN is defined as Virtual Local Area Network.

Which of the following are good reasons for using VLANs in your network design?

VLANs provide the following advantages:

  • VLANs enable logical grouping of end-stations that are physically dispersed on a network. …
  • VLANs reduce the need to have routers deployed on a network to contain broadcast traffic. …
  • Confinement of broadcast domains on a network significantly reduces traffic.

What are the best practices to use when implementing VLANs and trunks?

When configuring a trunk port, the Native VLAN should be set to the same value on each end in order to avoid Spanning Tree Protocol (STP) loops. By default, the native VLAN is set to VLAN 1. A recommended best practice is to change the Native VLAN to another unused VLAN where no hosts or other devices reside.
