IP – The Internet Protocol (IP) - is the method or protocol by which data is sent from one computer to another on the Internet. Each computer (known as a host) on the Internet has at least one IP address that uniquely identifies it from all other computers on the Internet. IPSec – Internet Protocol Security (IPsec) - is a protocol suite for secure Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session. OpenVPN - is an open-source software application uses VPN technologies in order to create secure encrypted point-to-point or site-to-site connections. Program Client – A client is a piece of computer hardware or software that accesses a service made available by a server. The server is …show more content…
Virtual machines operate based on the computer architecture and functions of a real or hypothetical computer, and their implementations may involve specialized hardware, software, or a combination of both. CA – Certificate Authority - is an entity that issues digital certificates. A digital certificate certifies the ownership of a public key by the named subject of the certificate. OSI – Open Systems Interconnection - is reference model for how applications can communicate over a network. A reference model is a conceptual framework for understanding relationships. SPI – Stateful Packet Inspection – is a method of monitoring the state of active connections in order to determine what packets to allow access through a firewall. QoS – Quality of Service - is the overall performance of a telephony or computer network, particularly the performance seen by the users of the network. VPN – Virtual Private Network - a method employing encryption to provide secure access to a remote computer over the Internet. DMZ – Demilitarized Zone - (sometimes referred to as a perimeter network) is a physical or logical subnetwork that contains and exposes an organization's external-facing services to a larger and untrusted network, usually the
A database is for the most part utilized for putting away related, organized information, with all around characterized information positions, in a productive way for addition, redesign and/or recovery (contingent upon application). Then again, a record framework is a more unstructured information store for putting away discretionary, presumably disconnected information. The record framework is more broad, and databases are based on top of the general information stockpiling administrations gave by document frameworks. There are additionally contrasts in the normal level of administration gave by document frameworks and databases. While databases must act naturally reliable at any moment in time (consider banks following cash!), give confined exchanges and sturdy composes, a document framework gives much looser
Authentication Header (AH) and Encapsulating Security Payload (ESP) are a part of the IPSec components, they are network layer protocols allowing secured communications through a VPN tunnel. Within a firewall to enable communication for AH one will use protocol 50 and for ESP protocol 51 (Frankel, Hoffman, Orebaugh & Park, 2008), both protocols 50 and 51 can be enable within the same end-to-end IPSec connection which is the Tunnel Mode connected by two gateways. Nonetheless, for Transport Mode, there are some restrictions in the order in which they appear. While AH supports connectionless integrity and authentication of the packets, ESP provides data origin authentication and confidentiality through the use of encryption, both AH and ESP provide
What does IP stand for and what is it used for? Internet Protocol, and it's a set of rules governing the format of data sent over the Internet or other
When people think of scientists, creativity is not always the first thing that comes to mind. Scientists are viewed as quite the opposite in fact, relying on cold, hard facts, rather than having the mind to create a colorful, bright work of art. However, nothing could be further from the truth. Scientists employ a great degree of creativity when drawing diagrams of observations, thinking of new ideas, and interpreting data in unique ways. Of course, all of the above is limited by the facts, for example you can’t just draw three extra legs on an animal because you want to be creative. However not all scientist’s drawings are going to look exactly alike because everybody is a different person. No two scientific papers are going to be the exact same either, in fact they could in fact be near complete opposites, depending on how one scientist
TOR (Roger Dingledine) is a circuit based low-latency anonymous communication service. TOR is now in its second generation and was developed from the Onion routing program. The routing system can run on several operating systems and protect the anonymity of the user. The latest TOR version supports perfect forward secrecy, congestion control, directory servers, integrity checking and configurable exit policies. Tor is essentially a distributed overlay network which works on the application layer of the TCP protocol. It essentially anonymizes all TCP-based applications like web-browsing, SSH, instant messaging. Using TOR can protect against common form of Internet surveillance known as “traffic analysis” (Electronic Frontier Foundation). Knowing the source and destination of your internet traffic allows others to track your behavior and interests. An IP packet has a header and a dat...
Internet VPN is a solution that utilizes a shared infrastructure in a way that provides you high performance and strong security. Internet VPN offers you the benefits of a private network (security, controlled performance) with the advantages of public networks (flexibility, scalability, redundancy, load sharing, performance, and lower costs).
In this paper, I will show you how TCP/IP allows a wide array of computer hardware to work together without ever having to know what the other machine is or how it even works. At the same time, you will learn how it allows information to find its way around the world in a fraction of a second without knowing in advance how to get there. Before we go too far, it should be noted that TCP/IP is really two protocols. The first is the Transmission Control Protocol (TCP). The second protocol is IP, which stands for Internet Protocol.
The latest version of the Internet protocol which we should be implemented is IPv4, also known as the TCP/IP structure. The reason why IPv4 is referred to as TCP/IP for the first two main protocols, out of its suite of protocols, which were developed by United States Defense Advanced Research Project Agency, also known as DARPA around the 1970s (Kozierok, 2005). ...
The overlay networking technologies have become very important part of the internet today as more and more sites are connecting to each other in all over the world. The overlay networking technologies give freedom to implement any routing protocol and network design on top of the internet. There are many proven overlay technologies are there, however they also have some shortcomings, which lead us think about more scalable and secure overlay technology. Some of the disadvantages of the overlay technologies that are currently being used are complicated configuration and networking topology, difficult in expansion and maintenance, GRE (Generic Routing Encapsulation) tunnel’s inability to traverse NAT, IPsec’s inability to support dynamic routing [1].
In today’s world businesses, governments, and individuals, all are communicating with each other across the world. While reality is rapidly approaching this utopian picture, several relatively minor issues have changed status from low priority to extreme importance. Security is probably the most well known of these problems. When businesses send private information across the net, they place a high value on it getting to its destination intact and without being intercepted by someone other than the intended recipient. Individuals sending private communications obviously desire secure communications. Finally, connecting a system to a network can open the system itself up to attacks. If a system is compromised, the risk of data loss is high.
The safe protection system of any rank all may introduce the concept of encryption. The data encryption has the very vital significance to the network correspondence and the data storage, it can play an important role of keep the data security, authenticate message, maintain the integrity of data and anti- denial.
...vantage of the overall network design and implement usable subnets with virtual local area networks. Use encryption and encapsulation to secure communications of public segments to enable extranets and cross-Internet company traffic. Use items such as intrusion detection systems and firewalls to keep unauthorized users out and monitor activity. Taken together, these pieces can make a secure network that is efficient, manageable, and effective.
This chapter provides an overview of cryptography concept. It`s required to encrypt and maintain confidentiality of the information to be transmitted over the network. This is achieved through cryptography. Cryptography plays a vital role in securing the information when transmitted across the network. It helps in maintaining the integrity of the information stored on the network. Thus, security is one of the important concepts to be explored in the world of network security.
IP is short for internet protocols. IP specifies the format of packets, also called datagrams, and the addressing scheme. Most networks combine IP with a higher-level protocol known as Transmission Control Protocol (TCP), which establishes a virtual connection between a destination and a source. (webopedia, 2014) The OSI, or Open System Interconnection, model defines a networking framework to implement protocols in seven layers. Control is passed from one layer to the next, starting at the application layer in one station, and proceeding to the bottom layer, over the channel to the next station and then back up the hierarchy. (webopediap, 2014)
There are a number of definitions of the network. Network is defined by Curtin (1997) as “A collection of interrelated links a net, a network of roads an interconnected cycle, a network of alliances.”This definition suits our purpose well which is a computer network is simply system of interconnected computers. As well as Ryan(2013)discussed" A network is one of information technology's interests. It is a nodes interconnected via communication paths. Also, it can interconnect with other networks and sub networks. By the way, networks are characterized in terms of spatial distance as local area network (LAN) ,metropolitan (MAN) and Wide (WAN)." In addition, Television Fanatic(2015) defined network in their own way which is "If you have group of computers connected to each other so, you have a network . It has main aim which is toenable the sharing of files and information between different devices. Cables are tools of network that can connected other devices together, for instance Ethernet cables or phone
