...VPN Concepts A virtual private network (VPN) is used to transport data from a private network to another private network over a public network, such as the Internet, using encryption to keep the data confidential. In other words, a VPN is an encrypted connection between private networks over a public network, most often the Internet. VPNs provide the following services: Confidentiality: VPNs prevent anyone in the middle of the Internet from being able to read the data. The Internet is inherently insecure as data typically crosses networks and devices under different administrative controls. Even if someone is able to intercept data at some point in the network they won’t be able to interpret it due to encryption. Integrity: VPNs ensure that data was not modified in any way as it traversed the re Internet. Authentication: VPNs use authentication to verify that the device at the other end of VPN is a legitimate device and not an attacker impersonating a legitimate device. Cost savings - VPNs enable organizations to use the global Internet to connect remote offices and remote users to the main corporate site, thus eliminating expensive, dedicated WAN links and modem banks. Security - VPNs provide the highest level of security by using advanced encryption and advanced authentication protocols that protect data from unauthorized access. Scalability - Because VPNs use the Internet infrastructure within ISPs and devices, it is easy to add new users. Corporations...

... A common carrier is a private company that sells or leases communication services and facilities to the public. Common carriers are profit-oriented, and their primary products are services for voice and data transmissions, both over traditional wired circuits as well as cellular services. Common carriers often supply a broad range of computer-based services, such as the manufacturing and marketing of specialized communication hardware and software. A common carrier that provides local telephone services (e.g., BellSouth) is commonly called a local exchange carrier (LEC), while one that provides long distance services (e.g., MCI) is commonly called an interexchange carrier (IXC). As the LECs move into the long distance market and IXCs move into the local telephone market, this distinction may disappear. 3. Explain how cloud architecture works. Cloud architecture is represented as a cloud with connection points. Users of circuit switched services lease the connection points (e.g., telephone lines) into the common carrier’s network, which is called the cloud. This architecture is very flexible and hides its internal details. Circuits can be established as needed between any computers attached to the cloud at any point. However, data can only be transmitted while a circuit is established, and only to the one location it connects to. These designs are simpler for the organization because they hide the common carrier’s burner of network design and management inside...

I use a variety of networks on a daily basis during the work week. To start, I work from home and I must first connect to my home LAN which has an internet connection. My home LAN consists of a router that shares my internet connection wirelessly. Next, I connect to my work’s LAN by using a Virtual Private Network (VPN). My work’s LAN consists of a router and several switches. On the network, there are several workstations, servers, printers, and various resources that I access to perform my job tasks. The VPN connection is also handled by a specific router for VPN access. In addition to my home network, work network, and VPN, I also have a cloud-based music service where I access my music that gets me through the day. The cloud based network is not local, but it is accessible over the internet at Google. 2) Binary data codes like EBCDIC, ASCII, or Unicode are often presented using hexadecimal notation rather than a long list of 0’s and 1’s.

...is the ability to log onto a network from a distant location. Generally, this implies a computer, a modem, and some remote access software to connect to the network. Whereas remote control refers to taking control of another computer, remote access means that the remote computer actually becomes a full-fledged host on the network. The remote access software dials in directly to the network server. The only difference between a remote host and workstations connected directly to the network is slower data transfer speeds. The purpose of a remote access policy is to define the standard connection to the company’s network from any remote host, untrusted host and remote network, including untrusted hosts on the company’s intranet. These standards are designed to minimize the potential exposure to the company’s from damages, which may result from unauthorized use of the company’s resources. At the main location, a set switches and routers are interconnected to from a Wide Area Network. The switches can be connected in different topologies. All remote users must follow the security requirements set forth in the standard for the company’s remote host accessing Information Technology Resources prior to such access, as well as any guidelines, procedures or other requirements issued by the Information Technology Department. Within the virtual private network multiple Virtual Private Network routers communicate securely with a central Virtual Private Network router. A separate, secured tunnel...

...Network Infrastructure Security Robert Collazo Rasmussen College Network Infrastructure Security The first thing that I will be covering is the virtual private network in windows 7. A virtual private network (VPN) extends a private network and the resources contained in the network across public networks like the Internet. It enables a host computer to send and receive data across shared or public networks as if it were a private network with all the functionality, security and management policies of the private network. This is done by establishing a virtual point-to-point connection through the use of dedicated connections, encryption, or a combination of the two. The VPN connection across the Internet is technically a wide area network (WAN) link between the sites but appears to the user as a private network link—hence the name "virtual private network”. The following authentication protocols are supported for logon security for VPN connections in Windows 7: * PAP Stands for Password Authentication Protocol; uses plaintext (unencrypted) passwords. * CHAP Stands for Challenge Handshake Authentication Protocol; uses one-way MD5 hashing with challenge-response authentication. * MSCHAPv2 Stands for Microsoft Challenge Handshake Authentication Protocol version 2; an extension by Microsoft of the CHAP authentication protocol that provides mutual authentication of Windows-based computers and stronger data encryption. MSCHAPv2 is an enhancement of the earlier MS-CHAP...

...access Ocper Inc. network would be through utilizing mobile virtual private network. Mobile VPN setting functions efficiently in situations where the endpoint VPN contains multiple access points. The mobile network can also be accessed using cellular devices carrying data between several Wi-Fi access points. These individuals could utilize modern I-phones, with capability to access VPN connections, as the network connection enables seamless roaming between networks through utilizing wireless connections. The advantage of utilizing this connection remains the ability for the network to connect between different IP addresses without losing information contained in other applications. The mobile VPN allows users to maintain several applications continuously open. While performing this function, the network also allows passing of data, securely over public networks. This capability would immensely assist employees Ocper Inc to access the network continually from several remote locations. Within office settings, however, the Virtual Private Network could be accessed through the conventional connection. This connection presents numerous limitations, making connections insecure when establishing remote connections. When the network becomes interrupted, information could be lost or computing devices could crash (Hallberg, 2009). This network connection, therefore, becomes limited to desktop computers and immobile computing devices. The mobile Virtual Private Network proposed, could be...
