Network Security Network security is a problem that network administrators face. It is something that network administrators should keep a careful eye on. For example, if the home network does not have any security measures in place, then the person is at a high risk of data loss due to hacking. Network security is something that businesses do not take very lightly because they want to protect their valuable information and network resources from hackers. It is a problem because of unauthorized use and can be resolved by increasing the security encryption levels. Networks, including the internet, are one of the most essential things to businesses. Without computer networks, companies would be lost and would not have a way to communicate without these systems and this would cause businesses to operate slower (Network 1). Patch works of older networking systems are easier to find these days (Network 1). Starting relationships between many businesses, networks in many ways become synonymous with the groups and businesses they bring together (Network 1). Business employees, customers, and business partners would have available access to their information stored in network systems, could get to their network systems and share them easily among themselves (“Network” 1). Computer networks give their owners speed, ability to connect, and ultimately value to their users. They give possible solutions for business difficulties and issues that would not be possible to other businesses (Network 1). Computer networking systems are required for electronic communications. (Network 1) As time moves on, businesses’ spend a ton of money on computer systems that are used to manage various functions such as accounting, human resources... ... middle of paper ... ...ained. (Kolakowski 2) “Now I can create spheres where workers manage their corporate email accounts and connections to the CRM to do their real work. The advantages of that architecture is that the user has greater separation between work and personal business, and isolation enhances security.” (“10 Problems 36) In the future of network security, there will be fingerprint readers. There will also be stronger encryption levels. Lastly, there will also be facial recognition software to protect the security of networks in the future and then again some hacker will gain access to it and start hacking it once more. Network security is something that network administrators must not take lightly. They must be aware of the causes that make network security an issue. Lastly, they must be aware of the problems and solutions to issues in network security situations.
Security of the companies data is one of the most important components which allows the business to perform its day to day operation using various networking devices, services that absolutely needs to be protected from intruders. Some of these devices include online transactions, the exchange of data between users and clients both internal and external and external web data needs to be secured. There are several polices that would need to be configured such as a web sever and firewall configurations. However, with these configurations the first and most important task is to identify any vulnerabilities or loopholes in security within the company. The company has both LAN (Local Area Network) and WAN (Wireless Local Area Network) and a web sever. These resources need to be secured at all times from hackers or anyone else by implementing the appropriate security measures.
Network Security is the protection of the computer’s network though out the entire infrastructure. It can protect very important information and computer files to help prevent theft, spyware, malware, viruses, and more. Depending on if you have a public or private network, can determine what type of security settings you need for your network. All people are different on what they want to have secured or not, but most people do not know how to prevent people or things from getting in their network. “You must have a general understanding of security terminology and specifications as it relates to configuring hardware and software systems.”(Roberts, Richard M. 599). That quote states that by knowing and understanding security terms and specifics, you can
In the following report I will discuss the role of network management and how the network manager contributes to the network security of an organisation. Network security will be discussed in full to inform on how big of an impact network attacks can have on an organisation. Once the impact of network security has been covered I will go through all possible threats that can harm an organisation and the steps network managers should go through to secure a network to the best of their ability. The importance of network tools will be introduced last along with benefits they can provide.
...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.
Threats can happen on a network regardless of the type, whether wired or wireless. Providing adequate security for the network should ensure minimal disruptions. The network threats can be broken into four classes to include: structured threats, unstructured threats, internal threats, and external threats. Structured threats usually come from individuals who have extensive knowledge of computer systems. These experienced hackers will attempt to extract information, commit fraud, and destroy or alter records on the targeted network. They will use whatever means they can to collect information about the systems on the network including phishing, pharming, and spoofing. Making company employees aware of these tactics can help prevent them from disclosing vital inf...
Network management planning and security planning involves identifying the best and most appropriate systems and hardware that the firm can use to better manage network and plan security systems. Therefore, the management required me to examine the best software and hardware systems in the market place that the company can adopt to enable it to manage the network and security. The management required me to advice on the implementation procedure of various plans that are going to be adopted. My responsibility also involved finding out or predicting the impact of the plan on the future operations. They required me to evaluate the challenges the company might face while adopting the changes in the network management plan and security plans.
So first and foremost we need to fully understand what is a network? A computer network is composed of multiple connected computers that communicate over a wired or wireless medium to share data and other resources. For instance, a home computer network may consist of two or more computers that share files and a printer using the network. The size and scalability of any computer network are determined both by the physical medium of communication and by the software controlling the communication.

Security is a word that comes from the verb to secure, which is to protect from harm. Security is meant of safety or protection to, for example, have activities involved in protecting a country, building or person against attack, danger [1]. Security is the state of feeling happy and safe from danger or worry [1]. Computer security is such a security that is considered to protect the computer system against attacks or harms. I refer computer system here to be comprised of hardware, software, data, and the user. Any attack or harm against the flow of data or information is to be defined as a computer security problem such as disruption of operations through viruses, worms and logic bombs along with unauthorized access [2]....
Whether the infrastructure involves a simple home network or a complicated corporate WAN (wide-area network), cyber security must always be considered. Protecting information and information systems is achieved through strong cyber security controls. Cyber security controls can be defined as any mechanism which ensures the confidentiality and security of information and information systems. Policy implementation can include, but is not limited to, training and awareness, policies and procedures, physical or logical security measures and government enforced laws. Since many organizations and individuals within the US work closely with intellectual property and national secrets, it is the responsibility of all parties to protect this
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.
Computer network security and honesty is a large concern among all type and size of companies. The option for solving security risks are as varied as the companies themselves. However, it is possible to break down the method for dealing with security risks into the major categories.
Whether a person is an occasional computer user, works in a major corporation, or within a government agency there is a dangerous risk out there. That risk is one that everyone must be concerned with, inadequate computer security. Computer security has become essential in today’s well connected digital world. Everyone wants to communicate with someone at sometime, and normally these communications need to be secure. If these communications are going through any sort of electronic device they are passing through some type of communications network. Whether the information is traveling around the world or just across the room to another computer this information is at risk. Safeguards must be implemented to the computers and networks that they use to protect them from viruses, intruders, and system failures.
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
A critical part of network planning involves setting up of security mechanisms. Deploying the network with security configuration provides superior visibility, continuous control and advanced threat protection across the extended network. Additionally, security procedures define policies to monitor the network for securing critical data, obtain visibility, mitigate threats, identify and correlate discrepancies.
An attacker looks for poorly configured network devices to exploit. Common vulnerabilities include weak default installation settings, wide open access controls and unpatched devices. To gather information from the encrypted network traffic attacker places the packet sniffing tool on the network. Sniffing is the act of monitoring network traffic for data such as clear-texts passwords or other configuration credentials. Usually transmitted information carried along during an Secure SHELL session cannot be seen but other information such as sender’s and receiver’s IP addresses, DNS requests to resolve hostname, port numbers and the amount of data is visible. If the traffic along the network is encrypted by the attacker, the attacker can see which sites are visited, amount of data received and sent and the port numbers used for the connection. Using a simple packet sniffer, all plaintext traffic can be read easily. This becomes possible because of weak physical security or lack of encryption during the process of sendin...
