Security is a topic that is gaining more and more interest by organizations and government agencies. The amount of data which organizations daily have to deal with, the increasing number of on-line transactions and the lack of computer security awareness are greater motivations not only to exploit software vulnerabilities but to exploit human vulnerabilities. In general, users tend to accept new technologies with complete disregard of their security vulnerabilities, if they get sufficient benefits from them. Fostering and continuously encourage a security culture and recognizing that people still are, and will always be the weakest link, will certainly assist organizations to achieve their adequate levels of security and thus becoming closer to their business goals. Moreover, monitoring and early detection also play an important role, as it enables organizations and governmental agencies to react more quickly to events that are harder to find and understand, from the security management point of view. The rapid response to the security events and the establishment of preventive actions to manage security are starting to become a competitive strategy to organizations. In this paper we highlight some information security concepts and principles, to deliver actionable information for decision makers for managing their corporate assets and ensure their resilience.

In this study we have discovered the issues of challenges in networking and cyber security that everything is dependent on latest technology, and the most significant feature of technology is the network. It is critical to limit the risk of threats to create a stable and reliable network environment for users. According to certain surveys, most security vulnerabilities are caused by "insider risks." That is, the hazards that arise within in companies are greater than the threats that arise externally. There are numerous tools and strategies that can be utilized in a network environment to address security issues and challenges. Although security risks and obstacles can be mitigated with the use of these tools and strategies, it is difficult to make a network completely threatfree. The fundamental cause for this is the rapid advancement of technology and the increasing use of it. According to surveys, security concerns are increasing day by day because of rapid technologica...

In addition to the advancement of the web, safety, as well as protection, came to be significant stress. Additionally, the background of security allows a much better understanding of the look of safety advancement. The net structure, on its own, enabled lots of safety threats to happen. The type of the world wide web, when regulated, can easily decrease the practical assaults that could be delivered throughout the network. Recognizing the strike techniques permits appropriate surveillance to surface. Many companies protect on their own, coming from the internet using firewalls in addition to the shield of encryption devices. Businesses make an "intranet" to keep connected to the internet but gotten from possible threats. This paper briefly discussed about the security threats, security vulnerabilities and advance network security policies.

Medium-to-large-sized companies are increasingly using their intranets to broadcast company-wide messages and store valuable information. Employees can choose to view multimedia-based messages from company executives, link to the latest product success stories, download the most recent technical specifications or refer to the most up-to-date pricing figures. Whatever the requirement, organisations have become very reliant upon electronic intra-and intercommunication methods. Whether it is sending an email with an attachment to a client, downloading information from the knowledge management system (KMS) or placing files in one another's public folders, employees now expect the technological capabilities to be available all the time.

Computer networks have arguably become ubiquitous (having grown exponentially over the last 15 years) and synonymous with organizations that thrive on excellence. Hardly will anyone set-ting up a firm today, do so without thinking of the modalities of incorporating an efficient computer network infrastructure that connects the business to the outside world especially via the Internet. This is because present day businesses depend heavily on platforms and network infra-structures that make communication easy, efficient, available and accessible. Robust computer networks provide such basis for interactivity, thereby bringing a whole lot of people and businesses together. Also, in this age of the internet, almost anyone anywhere, can access information from any part of the world. Consequently, all these have amounted to growing security concerns over the years, critical across sectors and industries. In this paper, a comprehensive study of some network vulnerabilities is carried out and counter-measures on how they can be prevented or contained to prevent malicious attacks and how to prevent wanton escalation in the event of a successful attack.

With the ushering in of the information age, a wide range of technologies in the field of computer science have emerged such that many network techniques are broadly utilized in different sectors of the society at large and in its wake not only has made great economic and social benefits, but also have immensely promoted the rapid development in culture and systems. While the openness and adaptability of computer network has brought us a ton of benefits both throughout our lives and work, it also has caused a series of information security problems which put our life at risk. With the fast advancement of computer network technology, ensuring the security of the computer becomes a very essential factor that cannot be disregarded. Three major threats confronting computer network security include: threat from hackers, computer virus and denial of service attacks whiles some measures leading to the safety of the network also include legal measures, technical measures as well as management measures. This paper seeks to investigate the primary risk confronting computer network security, address system security innovations and advances to help tackle the shrouded risk of the current basic system security.

— Information security is an important aspect that must be maintained in order to obtain a successful business. However, financial difficulties and budget constraints create problems in selecting security countermeasures to maintain the network and running the system. Network administrators must rely on labour-intensive processes for tracking network configurations and system vulnerabilities, which needs a lot of expertise and will cause an error prone. Organizational network vulnerabilities and interdependencies are so complex to make traditional vulnerability analysis become not adequate. Decision support capabilities let analysts make the balance between security and availability, and show how best to apply limited security resources. In this paper, we present a methods for strengthening a computer network security.

The popular press is replete with information about attacks on information systems. Viruses, worms, hackers, and employee abuse and misuse have created a dramatic need for understanding and implementing quality information security. In order to accomplish this, an organization must begin with the identification and prioritization of the threats it faces, as well as the vulnerabilities inherent in the systems and methods within the organization. This study seeks to identify and rank current threats to information security, and to present current perceptions of the level of severity these threats present. It also seeks to provide information on the frequency of attacks from these threats and the prioritization for expenditures organizations are placing in order to protect against them. The study then will compare these findings with those of previous surveys. r

Enterprise systems are continuously on cyberattacks as struggle for solutions are sort. Today, these organizations spend over $70 billion on IT security, but are unable to protect the organization since cyber criminals routinely discover exploits and breach those defenses with zero-day attacks that bypass traditional technologies. These attacks occur during the vulnerability window that exists in the time between when a loophole is first exploited and when software developers start to develop and publish a counter to that threat. Many organizations had been breached by the zero-day attack concept. This means that at least one attacker had bypassed all layers of organization defense-in depth architecture. Using data from our survey of 202 participants, this study analyses how attacks are changing the cyber platform and why traditional and legacy defenses are functioning below par and expectations.
