INTRODUCTION
Over the past few years, Internet-enabled business, or e-business, has drastically improved efficiency and revenue growth. E-business applications such as e-commerce, supply-chain management, and remote access allow companies to streamline processes, lower operating costs, and increase customer satisfaction. Such applications require mission-critical networks that accommodate voice, video, and data traffic, and these networks must be scalable to support increasing numbers of users and the need for greater
capacity and performance. However, as networks enable more and more applications and are available to more and more users, they become ever more vulnerable to a wider range of security threats. To combat those threats and ensure that e-business transactions are not compromised, security technology must play a major role in today's networks.
Why Networks Must Be Secured?
Attacks: -
Without proper protection, any part of any network can be susceptible to attacks or unauthorized activity. Routers, switches, and hosts can all be violated by professional hackers, company competitors. In fact, according to several studies, more than half of all network attacks are waged internally. To determine the best ways to protect against attacks, we should understand the many types of attacks that can be instigated and the damage that these attacks can cause to data. The most common types of attacks include Denial of Service (DoS), password, an...

...of security you really need. How important or confidential is your data? Do you have network connections with trading partners that have even more sensitive data? Implement security measures in proportion to your needs.
Stick with the standards. Standards not only ensure others have tested the waters, but protect your investment for future changes and expansion. Don't use default settings, obvious passwords or keys. Rotate your WEP keys oftenat least once per day or every 10,000 packets of information to foil hackers' efforts.
Finally, monitor, monitor, monitor!! Do not just turn your network on and assume it will always stay the same. Check and sniff your own network for APs you don't know about. Be aware of your physical environment. Look for any unfamiliar cars in the parking lot with someone just sitting in them? They might be trying to break into your house!
Network breaches are an ever-present and growing threat to network security. There are many ways that such breaches can occur, and the following material will analyze five case studies. The issues to be addressed will include, what went wrong, how could it have been prevented, and what measures could be instituted to prevent a reoccurrence.

This is only a small part of the prevention of infiltration of your network and computer. If one desires to learn more, go above and beyond and continue to learn on how to keep your network secure.
The fundamental reason why security protocols are implemented in networks is simple – to protect data as it traverses the network. The mechanism associated with protecting data on its travels is called cryptography. This particular mechanism employs algorithms which encrypt data so that hackers are prevented from easily intercepting the data. Cryptography operates in tandem with a group of protocols which help to control the passing of data between network devices. Therefore, security protocols are a vital component in networks in order to increase data security and without them security would be compromised (Linn, 2014).
Network hackers are forever inventing ways to break into the computer systems of organizations. Their aim is to take adventure of the susceptibilities of the system. Hackers remain only limited by the created activity of their minds. Hackers have the time, capability, and experience to infra trace any system. The organization has the responsibility to prevent hackers from infra tracing their system. Organizations remain required to plan for the assaults of hackers. Organization can only be better prepared to defend against hackers, if the organization has taken the necessary action to hinder the hackers’ assaults. There remain various ways in which an organization can prepare to do battle with hackers. The first step to battling hackers is for the organization to have an excellent understanding of its abilities and capabilities. Security analysis systems remain invented to aid organizations in the process of un...
The topic of network security is a reoccurring theme in today’s business world. There is an almost unfathomable amount of data generated, transmitted, and stored every day. Unfortunately the media and traditional reporting sources these days typically only focus on outside threats such as hackers. Many people completely overlook the insider threats that are present and can potentially pose and even bigger threat then any outside source. One of the acronyms that is constantly repeated in the security industry is the principle of CIA or confidentiality, integrity, and availability. Authorized users, whether by accident or through malicious acts, are in a unique position to threaten all three aspects of CIA.
This informational report will explain and guide you through the process and plan that will be implemented to prevent any unauthorized equipment (including external rogue switches) from entering the network. In addition we will be implementing the spanning tree protocol to eliminate any layer 2 loops and ultimately causing a network storm.
...vantage of the overall network design and implement usable subnets with virtual local area networks. Use encryption and encapsulation to secure communications of public segments to enable extranets and cross-Internet company traffic. Use items such as intrusion detection systems and firewalls to keep unauthorized users out and monitor activity. Taken together, these pieces can make a secure network that is efficient, manageable, and effective.
Security is often seen as exclusive requirement in networking, providing security is an important issue. A lot of problems are there so a lot of security measures should be provided. Security is more important than ever before due to many reasons. When a network is implemented poorly, security threats and ...
This is the information age. There are financial and corporate information, research and analysis, trends have lead the trend and military intelligence. Information classified as confidential, sensitive and critical. There are gleaning information extraction and automated tools. There are management solutions, such as content management, knowledge management and document management, information management collected for. There are different mechanisms for storing information storage. Finally, information security, there are tools and techniques. In this paper, three important types of security information we need to discuss, such as security information from hackers, during transit to ensure that information and the protection of information stored in the system can be lost or stolen. Finally, a brief about wireless security has been described here. The Internet has become the information superhighway. Evolving Internet and related technologies have allowed companies to communicate in new ways with all types of people and strategic organization. Over the years, there have been increased after the distinctive features of Internet connection. As needs change, the more powerful the service of humanity encountered, faster connections, and what can be done in the need for more flexibility. Initially, the service, such as a simple POP3-based email and Web access is the extent of an Internet connection. Today, we have a site-to-site virtual private network (VPN), clients and home users VPN, streaming media, Web-based training, wonderful Internet applications, e-commerce, and business-to-business extranet. Therefore, the development of the Internet to meet the needs of a variety of advanced human society. On the home front, fr...
According to the SciTechConnect blog [1], “In today’s network infrastructures, it is critical to know the fundamentals of basic security infrastructure. Before any computer is connected to the Internet, planning must occur to make sure the network is designed in a secure manner. Many of the attacks ...
Cyber attacks on the Internet occur on a daily basis - ranging in size, form, mechanism, level of sophistication and impact. Some cyber attacks can merely be a nuisance that affects a relatively small number of people with an easy fix, while other attacks can be detrimental and costly affecting millions of users (Kramer, Starr, & Wentz, 2009). It is now more apparent than ever that effective cybersecurity defensive technologies and policies need to be designed and implemented to counter the full range of cyber attacks that occur at the enterprise, national, and international levels.
This paper will also discuss several methods to mitigate and protect a wireless network against security attacks.
Robust information systems and communication networks have become essential in social and economic development across the world. Networking and computing are currently utilities in the same way as water supplies and electricity. For this reason, the safety and availability of information communication systems are becoming of increasing concern. Computer security is essential to any institution and government agency and with the ever-increasing rates of computer-related crimes, it is essential to establish security program capable of preventing the impact of such threats. Various institutions globally are increasingly integrating advanced information communication technology infrastructure and applications in their core operations
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.
Easy information access also opens the door to numerous security threats. The job of the enterprise network management team is to detect and respond to all the potential threats in a quick and decisive manner. While most network security systems can do this, there are some disadvantages associated securities in network
