Network Security : Information Security

Network security consists of the provisions and policies adopted by a network administrator to prevent and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. Network security involves the authorization of access to data in a network, which is controlled by the network administrator. Users choose or are assigned an ID and password or other authenticating information that allows them access to information and programs within their authority. Network

Network security has become more important to personal computers users and many big businesses. Network security is made up of policies provided by the network administrator to prevent unauthorized access, misuse, modification, or denial of a computer network and network accessible resources. It starts with authenticating, this is commonly with a username and a password. Because just one detail is

Networking security the process of taking physical and software preemptive evaluations to protect the underlying network foundation from unauthorized admittance, misuse, glitch, modification, demolish, imprudent revelation, thereby creating a secure platform for computers, users and programs to implement their permitted critical functions within a secure environment. Network security has become significant due to the patent that can be obtained through the Internet. There are essentially two different networks, data networks and synchronous network composed of switches. The Internet is considered to be a data network. Since the prevailing data network resides in computer based routers, information can be accessed by special programs, such

One of the most important aspects of network security is a strong network security model. The network security model consists of seven layers that work together to provide the strongest possible security for the network. The seven layers are the physical layer, the vlan layer, the software layer, the user layer, the administrative layer, and the IT department layer. A network security model that is well thought out and designed allows the network security team to analyze and maintain the network and determine if there has been a breach and the location of the breach.

Network security has been instrumental in providing security to different types of networks. There are various types of networks like LAN, WAN and MAN for which the security is provided in order to protect them from various unethical activities. The network security has also grown with the recent advances in technologies. It is also very flexible in terms of providing security to advance and new platforms like cloud environment, virtual environment, wireless environment.

Many believe that the only reason that we need information security is in order to ensure no one can hack our computers and to ensure that our important information is never lost. Information security is not only that, but on the other hand there are many reasons why we need information security.

Network Security is an approach and plan for establishing the security for organizations like universities, industries. IT Security Policy is the basis archive for Network Security. Security is a control for protecting networks and systems across risks such as hacking, data exudation, malware, spam, Denial of Service Attacks (DoS). An essential component of the network security paradigm is the idea of perimeters of defense that must be implemented if the network is to be both secure and usable. Certainly, it is possible to create a quasi-secure network by eliminating connectivity and interaction among systems and me other networks (White & Rea, 2007). This view is on altering flexibility to the obligation of IT security in organizations with business networking applications. Our analysis shows that privacy is a confirmation to quantify and update reliable connection and dependable interactions between participants of business processes and their IT systems (Wohlgemuth, Sackmann, Sonehara, & Tjoa, 2014). Software Defined Networking (SDN) paradigm helps a lot in network field. It separates the control plane from the data plane to enable programmability and centralized command of the network framework, the SDN design not

It is important for ABC Corporation to bring the network up to current security standards. Attempts to breach networks are becoming more sophisticated and difficult to defend against, as more powerful hardware is introduced and new security defenses become available leaving older measures unreliable. Aging networks that are improperly secured are more at risk than ever. It is not only important to ensure you have the proper defense at the perimeter but also internally on wired and wireless infrastructure. When considering network security controls, acceptable risk is often considered but needs to be minimized to provide the smallest attack surface for an attacker to exploit.

Keeping a network secured is always mandatory because information cannot be share by a person who is unauthorized and network security is an advanced procedure where it will prevent possible access or misuse of information on network or modify any data on the network without having an access to it. There are several ways of network security by which a network can be secured.

Now-a-days security is one of the major concerns for system administrators and internet users. Appropriate level of high security is always required to protect confidential data, to lock a system from unauthorized usage. Threat of internet security breach is

The world is becoming more interconnected with the advent of the Internet and new networking technology. There is a large amount of personal, commercial, military, and government information on networking infrastructures worldwide. Network security is becoming of great importance because of intellectual property that can be easily acquired through the internet. When considering network security, it must be emphasized that the whole network is secure. Network security does not only concern the security in the computers at each end of the communication chain. When transmitting data the communication channel should not be vulnerable to attack.

The development of technology has brought Internet to become the mass communication media between people or companies. Through Internet, people can communicate with other people in various places. Companies can get many advantages by using Internet network to support their business. Therefore, companies are trying as hard as they can, and give high effort in protecting their network from attack and make sure that they have the best network security.

The increase in the usage of the computer networks leads to the huge rise in the threat and attacks. These attackers change, steal and destroy the valuable information and finally cause complete damage to the computer system of the victim. They affect the performance of the computer system through the misconfiguration activities and generation of software bugs from internal and external networks. Irrespective of the existence of various security mechanism, attackers often attempt to harm the computer system of the intended legitimate users. Hence, security is a main factor for the efficient operation of the network in various applications such as healthcare monitoring, military surveillance, etc. The most common security mechanisms are firewalls, antivirus programs and Intrusion Detection System (IDS).

I could now confidently say that the addition of this course Business Computing Environment and Networks to the curriculum has tremendously helped me gain more knowledge about the basics of the Networks, how it is being managed, its security, and also how to be more aware of the problems that are being caused nowadays due to the lack of Internet security. As a part of the learning and to my best understanding from this course, I would like to delve more into the most common internet security problems and how do we solve the business problems through the Internet Security.

The fastest growing element of the computer world is the internet, due to this development the internet has now become the main communication method within the current generation whether that is between people or companies. The internet has a lot of benefits, people and companies can communicate and connect with others in various locations, therefore companies can take advantage of using the internet network to support their business, however there are some disadvantages to this method, using the internet heavily to communicate can leave companies and people vulnerable to cyber-crime such as network attacks, this results in companies taking extreme actions to have the best network security possible and maximise efforts to protect their network.
