OpenVPN is an open-source software application that implements virtual private network (VPN) techniques for creating secure point-to-point or site-to-site connections and remote access facilities. OpenVPN allows authentication using certificates or username/password. OpenVPN can work in two different modes regarding encryption. It can use static encryption or Public Key Infrastructure (PKI). The advantage of static encryption is that it is very easy to configure. The disadvantage of this type setup is that if your encryption key is compromised, all VPN data can easily be decrypted. The PKI mode resolves many of the issues static encryption has. It
When setting up a LAN the architecture that you decide to choose is important. There are several factors that are decided when choosing said architecture, some of these being network speeds, types of cables, and access control mechanisms like collision detection (Team, 2011). The most common on in today’s LANs is Ethernet. These can be either wireless, wired, or a hybrid of both.
There are various types of equipment that the company should look for when considering this network. The first item to look at when considering equipment is the Operating system and software that we would need. Next, the group took into consideration the type of server the company needs to make this network a reality. Another thing that we looked at is the possibility of having ThinClients over regular desktops for all workstations. Of course, it was taken into consideration that some employees would not want ThinClients. So, we show the type of tower we plan to place into those spaces, along with any peripheral device for both. Then, we will look at the network devices that will go into each building that include switches, routers, repeaters, hubs, and wireless access points. Finally, the group will note guidelines for choosing a local ISP at each site. Each Item outlined helps to build a network based on the specifications given by the company.
LAN stands for Local Area Network. LAN is a type of network that interconnects computers and devices either wired or wireless and covers a greater distance. LAN is mainly used in private organisations such as college or university. More or less everyone uses wireless router at home these days and the user is able to connect between 5-10 devices wirelessly. The user can share the broadband or the connection with ADSL by using Ethernet cables. Smaller LANs can connect at least
VPN configurations will be used between each location to ensure site-to-site connectivity. The VPN will allow employees to access the company's intranet from home or while traveling outside the office, and site-to-site VPNs allow employees in geographically disparate offices to share one cohesive virtual network. A VPN can also be used to interconnect two similar networks over a dissimilar middle network; for example, two IPv6 networks over an IPv4 network. which will
VPN is a private network that uses a public network, usually internet, to connect remote sites or users together. It uses virtual connections routed through the Internet from the business's private network to the remote site or employee. VPN is used mostly by the employees who prefer to telecommute or work away from the office. By implementing VPN, the businesses make sure the data is encrypted and can’t be read by the ones who try to intercept the data. The computers at each end of the tunnel encrypt the data entering the tunnel and decrypt it at the other end. An encryption key determines what computations to perform on data in order to encrypt or decrypt it, however, a VPN needs more than just a pair of keys to apply encryption. Hence, a
Local Area Network or LAN for short is the term used for computer networks located at a single location such as a small business located at a singular location. They are generally used for businesses, organisations and the likes to transfer data amongst their systems as opposed to transferring data to outside of their location. A LAN typically will rely on wired connections due to the benefits of increased security and speed, but a network called a WLAN exists, which is a Wireless Local Area Network and this may prove useful for those who come to work using mobile devices such as laptops, phones, etc. WLANs are simply local area networks that consist solely of wireless connections using a wireless access point (WAP) as the central hub. However, LANs can be a mix of both wireless and wired.Typically in a LAN, systems connected to the network are able to share resources among each other, send data to servers and use peripherals such as printers, scanners &
Local area network (LAN) is a wireless network that is mostly used in a work place or small building. To be able to make this work, you will need an access point connected to a switch to create the wireless network. There are different types of hardware components that are used to set a wireless network up such as network adaptors, Ethernet cables and a hub.
A VPN offers mobility and security for remote workers. The VPN uses an encrypted connection using the Internet. Remote workers wanting to use the Internet file server need authenticate their identity with a login id, password, RSA token, or smart card. The VPN can be used on company-owned laptops and personal electronic devices (PEDs). The VPN works by using data encapsulation. Encapsulating data packets into another set of data packets and data header this is the ‘tunnel’ used to send private data through the Internet. The data reaches its destination where the data is extracted from the 'tunnel'. It is then sent to the Application Layer where the remote worker can view or retrieve the files. This is a dedicated connection between the company and the remote worker computer. It is failsafe; the data sent through the VPN is encrypted by the sender and decrypted by the receiver. This prevents the data from being altered, read, or stolen by a hacker. Different cryptographic rules on each layer of the OSI model provide secure data transmission, authentication, confidentiality, and nonrepudiation. The cryptographic tunneling rules implemented for data security in each of the OSI layers (starting with the bottom layer) are listed
A local area network (LAN) is a computer network within a small environmental area such as a home, school, computer laboratory, office building or group of buildings. A LAN is composed of inter-connected workstations and personal computers which are each capable of accessing and sharing data and devices, such as printers, scanners and data storage devices anywhere on the LAN. LANs are characterized by higher communication and data transfer rates and the lack of any need for leased communication lines.
LAN refers to Local Area Network. This is a network of computers in small areas. It is usually used in organizations, schools or even at home. A Local Area Network can be created with Ethernet cables and its components or via wireless technology. A Local Area Network has reduced security threats to its data in that for a person to access the data, they need to be within the small region with coverage which is mostly within the company’s or organization’s premises. As a result, this reduces the risk of unauthorized persons accessing the data.
There are several types of network infrastructures that are commonly used within healthcare organizations. The most commonly used network is the Local Area Network (LAN) that is used to connect digital devices and computers within the building of the healthcare organization. In addition to this, WLAN and WAN are used to spread the network when different parts of the building are to be connected or different departments in an organizational complex are to be connected.
Star topology is one of the most common network setups. In this arrangement, every node connects to a central hub, switch or computer; the hub acting as a server and the peripheral devices as clients. A major disadvantage of this network topology is that if the central hub fails, all of the connected devices are disconnected. In a star network layout, each workstation is connected by its own cable directly to the server. Star networks are usually the layout of choice in schools and offices because they tend to be the most reliable of the topologies. The visual example shows how this setup gets its name as it is shaped very much like a star.
