Network Security And Its Effect On Organizations

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

The world of cyber security continues to introduce new threats each year against network infrastructures and computer devices. In the recent years, the impact from cyber-attacks has wreaked havoc on many company brands and organizational reputations. As this issue grows so does the technology to prevent and protect against these malicious attacks. It is absolutely crucial for organizations and businesses to shift focus from defense for different types of attacks to improving safeguards to mitigate the loss of sensitive data when an attack occurs. In addition to the traditional security technology used to detect an attack, companies will have to include

Security will always be a driving emphasis for the success of an organization. As technology continues to grow and develop, there is a greater need for understanding threat environments. The growing anxiety with security and privacy concerns make receiving a virus on a personal or company computer dangerous. It is vital that both individuals and organizations take the time to understand how to protect themselves from schemes used by hackers. It only takes one mistake for a hacker to have control of your computer. A proper understanding of security offers direction for improving business procedures and educating users of acceptable threat management and authentication practices. The management of network and application security

An analysis on the vulnerabilities as well as the use of cyber intrusions in an organizational network has become key for running businesses (Sengupta, Mazumdar & Bagchi, 2011). Enterprises including academic facilities, government parastatals and manufacturing firms are started to carry out business. The organizations mentioned above will in one way or another need an enterprise network to ensure that there is smooth running of operations for success in their undertakings. The network is made up of software and hardware systems, transmission media, devices and employees. Different organizations

Because network security is extremely important, businesses need to make it a top priority to have a network infrastructure assessment. Networks are becoming increasingly complex and by executing a network assessment it will help IT managers ensure the company’s network is operating at peak efficiency. “The vulnerability of the system depends on the state of the system itself, on the capacity of a hazard to affect this state and on the undesired consequences the combination of the hazard and the vulnerability will eventually lead to” (Petit & Robert, 2010). Known vulnerabilities of a security infrastructure require a situational awareness. “This includes knowledge of security software versions for integrity management and anti-malware processing, signature deployments for security devices such as intrusion detection systems, and monitoring status for any types of security collection and processing systems” (Amoroso, 2011).

Traditionally, IT (Information Technology) security focused on securing the IT assets within the organization’s IT framework. However, with the advent of smart mobile devices, cloud computing, and remote connectivity, the IT landscape has changed dramatically in the last few decades. With these changes, the frequency of attacks by cyber criminals has increased as well. We constantly hear news reports of large-scale cyber attacks targeting financial, government and healthcare organizations. Moreover, the type of attacks have evolved to become more sophisticated and untraceable, making it difficult for security analysts to keep up with the every changing technological demands to successful prevent, analyze and thwart security attacks. This has now led many security experts to believe that having an effective defense mechanism in place is a much viable option than to be reactive to threats. This also makes sense from a business perspective. Companies want their IT investments to further their business goals and not to be constrained too much by focusing heavily on IT security, which could potentially lead to an increase in operational costs to tackle security issues.

One of the biggest challenges that businesses face today is planning and preparing for security breaches, especially how to react and respond to cyber security incidents and security breaches. Security-related threats have become quite a nuisance and are more diverse than ever before. The security-related threats have become more disruptive to business processes and more damaging to company’s reputation. With preventative activities encompassing the results of risk assessments, penetration tests, and an effective vulnerability management programs can lessen the effects and decrease the impact of incidents. There is no way to completely prevent all incidents from happening within the company’s networks during day to day operations. Having

As networks continue to increase with industry growth, information security demands more and more attention. Security breaches are triggering a lack of trust among patrons and loss of revenue to many businesses. Protecting an organization’s data is the responsibility of any user who accesses a network or maintains a network. Employees—usually those outside the IT team—require proper training and a sense of urgency to prevent attacks.

Computing technology has changed the way users work, learn and play-More businesses have gone online. They have turned into a vital piece of our regular presence. These computer system are vulnerable against various internal/external threats like malware in both homes business and environments and this has rapidly escalated firmly over the past several years. Information in this systems needs to be protected from intruders because it’s an essential asset in the organisation. Three basic important things need to be supplied is integrity confidentiality and availability of information. The diversity of risk to the network computing by disenchanted attacks has intensely maximised worldwide. This is according to the U.S federal bureau of investigation .The digital attacks globally have reached 20,000 in January causing more than 8 billion dollars damage (Mueller, 2003).

We won’t stop emphasizing on the importance of information security in every organizations. As a team of conscious security experts, we know the extent of damages you can incur as a result of poor or weak security settings. Like we usually say in most of our publications, information security is a serious business, which must not be overlooked by any organization. There are many questions and issues we need to tackle as far as information security is concerned, but unfortunately, we won’t be discussing them here, as we have already prepared a comprehensive and exclusive courses for each of them. However, if possible, we would discuss some of the issues in this article.

This paper describes the basic threats to the network security and the basic issues of interest for designing a secure network. it describes the important aspects of network security. A secure network is one which is free of unauthorized entries and hackers

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.

1 Everyday we see innovations, new technology in the market, updates, upgrades. The world is moving forward and it is moving rapidly. Businesses around the globe are becoming more dependent on an ever-increasing selection of IT systems and technologies more and more as time goes on. Furthermore, they need to be interconnected with their suppliers, venders, customers and business partners. The dependency on technology combined with interconnection of their business and rapid increase has increased the potential of cyber security risks. Cyber attacks are not just an IT problem; they are more a business risk. Hacking has evolved from hackers to hack for fun to just look for technical vulnerabilities to being sponsored attacks that are targeting specific industries, sectors, companies, and individuals. Cyber attacks methods evolve incredibly fast, complexity, and impact with new, more complex cyber risks everyday. “Many organizations across the industry spectrum are suffering from substantive technology debt.” (PWC.com). Companies are so focused with their emerging business technologies, but they forget that their IT infrastructure is suffering. Their IT infrastructure is aging and it is getting to the point that it cannot even support basic data security functions. Yes, Technology has grown its influence on business, such as “mobile solutions, social media, alternative workplace solutions, collaborative product innovation, digitized healthcare, and telemedicine.”

Today’s “Cyber Domain” is growing rapidly to keep pace in an ever more competitive world. Businesses are adopting new ways of doing Business due to the increasing dependency on networked communication devices, network access points and cloud-based services. Building a sophisticated Computer Network Defense (CND) plan in order to protect, analyze, monitor, respond and detect unauthorized access to computer networks is becoming increasingly difficult. Sophisticated cyber criminals are taking advantage of rapid business digitization and evolving IT

Computer network Security is the most essential and complex topic in IT field. It is important that all user must have an awareness about computer network security. Internet is a biggest network in the world which connects all computer devices in the world. In our daily life millions of people communication each other by using internet. So it is very difficult task to protect data which is transfer through internet. So many pioneers are try to hack the information of well reputed organizations for their personal benefits.
