Network Security : Information Security

Accessing other user’s files: Users may not alter or copy a file belonging to another User without first obtaining permission from the owner of the file. Ability to read, alter, or copy a file belonging to another User does not imply permission to read, after, or copy that file. Users may not use the computer system to “snoop” or pry into the affairs of other users by unnecessarily reviewing their files and e-mail.

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.

There have been recent innovations in protecting the most important resources of the network. More advanced security technologies are employed on the network in order to take advance precautionary measures to avoid various security threats. According to various situations companies adopt the required security measure in order to address different types of unethical activities on the network.

Network Security is a very dynamic and technical field dealing with all aspects of scanning, hacking and securing systems against intrusion. It is more than just encrypting user data, virtual private networks or installing firewalls. Network security consists of the provision, policies adopted by a network administrator to prevent and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources (Xie, 2013).

This paper is intended to speak the network security in a brief, more focus on the strategies and practical implementations to be done for a successful and secured Computer networking and Information systems, minor the possible threats and challenges against them and with a conclusive discussion of importance of rapid research for secured computer network system.

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.

The Global Security Act also includes Global Network Security. Network security consists of products and services used to monitor, detect, and prevent unauthorized access, misuse, malfunctioning, and destruction of a computer network. It helps to provide and maintain a secure platform to enable users in the network to perform their critical tasks. Network security is increasingly gaining prominence especially because the number of hackers who want to extort money or steal critical information has increased. Not only has the number of networks security threats increased, the level of sophistication is much higher and traditional defense mechanisms are no match for these threats. Organizations, both large and small, have begun to realize the importance of network security systems and have increased their investment in network security. In addition, there is now a growing realization that network security systems can also increase workforce productivity,

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

Network security has become a major concern in the computing industry, including organizations, personal users and the military. The reason for this is due to the large number of security threats that occur on a daily basis. The internet architecture itself allows many threats to

Information systems and data security to organization has in the recent years increased drastically. A computer can be illustrated as a device that is mainly use to process data into information which is useful to the user. The expert who deal with Information and technology related safety measures are resourceful when it comes to the process of information system and data protection. This will ensure that the data which belongs to companies remain confidential and inaccessible to unauthorized people.

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).

This Security of the information plays a major role in the business and its continuity. Not only in the areas of business, is security of information
