Network Security : A Security Platform For Users, Programs, And Computer Networks

Despite the presence of network security devices such as firewalls and other security appliances, today's corporate networks are still vulnerable to both internal and external attacks by hackers intent on creating havoc. By proactively

In this modern day and age of computing, networks are a huge part of IT. It is important now more than ever that data sent over any network, whether it be a LAN (Local Area Network) or WAN (Wide Area Network; The Internet) is kept safe, private (when required) and uninterrupted in

Security is almost certainly the most difficult aspect of a network to perfect. It is important to have the correct procedures and components in place to make certain network security is being accounted for and addressed on any given network. The journal, “Future Generation Computer Systems” elaborates on this necessity for an information system. “Future Generation Computer Systems”, this component of a network is discussed thoroughly. “Essentially securing an Information System (IS), involves identifying unique threats and challenges which need to be addressed by implementing the appropriate countermeasures” (Dimitrios Zissis, Dimitrios Lekkas, 2012). This was achieved through configuring access lists as well as CHAP configuration on the routers connecting to the edge

Firewalls are set up on computers to help protect computers and other devices from attacks from potentially harmful websites and other resources. Proxies are servers that act as a middle man for computers. They allow users to make indirect connections to other servers. The LAN-to-WAN domain is where the infrastructure connects to the Internet. Updates, firewalls and proxies will help to keep things running and help to keep it protected.

I am Professor Kirk Mooring and I will be your instructor for this class. In this class, you will learn the fundamental core theories of information and network security. In this course, you will learn and use technology skills that are in demand in today’s job market. With so many threats and vulnerabilities created daily that we have to learn to work as a team in order to protect our data with the appropriate security safeguards. You will study the concepts that will help you evaluate and mitigate risk by selecting the appropriate security controls and technologies.

Network Security Issues – major threats and the means to fight them Network security issues are the top priority of all who want to protect their data.

Security in the age of internet has become a tremendously important issue to provide comfort not only for paranoid people but for many others who are naïve to believe that protection in digital era is essential to communication between millions of people that increasingly used as a tool for commerce.

Network security has changed significantly over the past years. There is more and more data to monitor and analyze in order to detect the activity of your data and systems. Securing a network has many variables. Password authentication, network access, patches, anti-virus protection, intrusion detection, firewall and network monitoring tools are just a few of the things you can do to protect yourself.

The correct configuration of security technologies is mandatory to balance the need for access and safety of information (Cavusoglu & Raghunathan, 2009). Many companies use the layered approach to ensure protection of their network information system (Cavusoglu & Raghunathan, 2009). By using this approach, many security technologies rely on each other to operate effectively (Cavusoglu & Raghunathan, 2009). Three technologies commonly used together are Intrusion Detection Systems, Intrusion Prevention Systems, and firewalls. When configured properly, these technologies complement each other (Cavusoglu & Raghunathan, 2009).

As a staple of communication and research at Edu Corp, computer-based networks play a critical role in the day-to-day operations of the company. With the ongoing concern regarding network security, Edu Corp has established a comprehensive, detailed policy in order to protect our digital assets, but most importantly, our employees and customers. Since 2014, nearly thirty major companies have been victims of cyber-based attacks, resulting in millions of dollars in losses (Walters, 2015). At Edu Corp, we strive to implement cutting-edge, proactive security solutions to our various networks.

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

Modern businesses are faced with major security threats especially to their information systems. The complexity of systems has not helped in mitigating these threats. With the massive adaption of information systems within organizations, they have become the cornerstones for organizations and this has made the systems more vulnerable to sabotage and potential attacks. There are both external and internal threats to information systems, which can be accidental or intentional. The threats to information systems are multilayered, and they can affect a couple of components like networks, software applications, operating systems, intranet, internet, and wireless technologies.

Safety of information is the most valuable asset in any organization particular those who provide financial service to others. Threats can come from a variety of sources such as human threats, natural disasters and technical threats. By identifying the potential threats to the network, security measure can be taken to combat these threats, eliminate them or reduce the likelihood and impact if they should occur.

The forefront and need of Information and Cyber Security has progressively spread as communication media as well as the exponential growth rate of electronic storage and information transmissions increase at astounding proportions. The need for Security today has never been higher equally for private and organizational use. There are many significant reasons behind the growth of Security in both Information and Cyber fronts. Per (Yildirim, E. Y., Akalp, G., Aytac, S., & Bayram, N., 2011) these are classified as the increase in electronic applications in businesses and daily life, sharing information on network systems, accessibility of information from many points, the increasing threat of loss of information, and most

Network security has had to adapt increasingly quickly, in order to keep up with the new ways that users and back-end systems work. Mobility and variety are currently on the increase at both sides of the enterprise network. At the outer edge, users are operating a growing range of hand-held computing devices. At the inner edge, virtualized servers, new storage devices (NAS and SAN), and data backup mechanisms are replacing what used to be a simple cluster of static servers. Both user needs and business needs are adding new requirements to the list of features that a network must support. New personal computing devices, with modern operating systems and brand new capabilities, are materializing at an exponential rate. Almost as quickly as a new technology is invented – even one that previously seemed like fantasy, for example making a video call wirelessly while walking around a building – it becomes a necessity. The era of static desk-bound PCs, running a prescribed OS image and a prescribed set of applications, has passed. The enterprise network must now be a more open platform.
