Nt1310 Unit 3

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

There are several different types of firewalls a company can purchase to insure their information is kept secure and only accessed by those who the company has given access to. A firewall can be purchased from an application service provider who can maintain the software for the company, this can

The main security concern of many organizations nowadays is how to prevent or mitigate the risks coming from portable devices such as tablets, smartphones and laptops. Each of these devices connecting to the corporate network creates a potential entry point for security threats (which is called endpoint). Another concern is how to secure the data which resides on portable devices of their employees. This needs to be done in such a way that even if the device falls into wrong hands, the data should be protected. These two concerns can be resolved with the help of endpoint security.

Deciding what type a network to use a local area network(LANs) device the end-user uses to access the system is the client. The install requires clients, Servers switches, router, and media. The network needs a topology to rapidly placement of all components and devices. For example, you can use the ring topology. Topology ring allows devices on a circle to make turns transmitting the ring connection for media access was out a problem. Security is a big deal so many cyber-attacks companies must be to protect their clientele privacy.

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).

IV. Overview of the many possible threats/risks that both home and corporate WIFI networks will need to overcome to provide the desirable level of security.

In order to minimize security threats and establish policies to protect a business, the owners or I/S specialists need to recognize the threats that could potentially happen to their business. Some common security threats include viruses, which could rewrite code creating the software program to be unusable or destroying the data as a whole. Viruses can spread quickly and many are not caught until damage is already created. In order to mitigate these risks, there must be a security plan in place. This could include an antivirus software, or a firewall. A firewall is a “hardware security device that is installed between a computer network and the internet. It acts like a web server, routing traffic, but also blocks external users from

     Out of 20 people surveyed, 15 stated a firewall as most important, 5 said anti-virus software. In my opinion, anti-virus software is the most important security measure followed by a firewall. This is because viral attacks seem to be much more prevalent than hacker intrusions. My analysis of this data is that most people are aware that firewalls provide network security from intrusion, but take anti-virus software for granted.

Securing the network is a top priority for any organization that is planning to run a modern day business. One of the major concerns is network attacks, whether they be inside or outside attacks, these attacks have the potential to cause an organization to lose business. It is important for these organizations to have a highly available, secure network design. This will provide a secure, redundant network that will be available for the business even when the network is experiencing issues.

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

The company must first be aware and understand the risks of a VPN and firewall. This knowledge will help the company make the right decision for this technology. A VPN and firewall solution is different for every network, and must be customized to this company’s network. There is also risks to not using these tools. It is important for the company to see this risks as well, so

A-3 A computer network is a network which allows computer to exchange data. A lan only covers small areas like schools, café, offices whereas WAN covers large geographical areas like

Routers: We require a router to be installed at the edge of the network. There are various sellers but two popular ones are Cisco and Juniper. Cisco and Juniper have a wide variety of products and they provide quality products. Examples of these products are Cisco 2900 series router, Juniper ACX1100 router.

As the technology is growing the security threats are also increasing at higher rate. So, as to protect an organization from such network security threats severe actions and several steps have to be taken by network security administrators. In any large organization that is having large number of big servers, firewalls and interconnected network of hundreds of computers, security is one of the most important aspects so as to secure its network from intruders. Within the organization, all the computers and devices are interconnected in a LAN network or using a WLAN (Wireless Local Area Network). So, the most important task of network security administrator to secure its internal as well as external network from intruders because there are several ways intruders can sniff the network and resulting in heavy loss of data. There are several threats that can affect network security of an organization such as: Wireless Sniffing, DoS (Denial of Service), sniffing of VoIP network, trojans and unauthorized access to FTP server.

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).
