New Security Tools and Techniques Network Security consist of scheme adopted by a network administrator to prevent and monitor unauthorized retrieve, misuse or alteration of a computer network and network available resources. Network security includes the authorization of access to data in a network, which is measured by the network administrator. Users choose or assigned an ID and password or authenticating information that allows them contact to information and programs within their authority. Network security covers a selection of computer networks, both public and private that are used in everyday jobs directing transactions and communications among businesses, government agencies and individuals. Networks can be private, for example within a company and others which influence be open to public access. Network Security is involved in organizations, creativities and other types of organisations. It secures the network as well as protecting and control operations being done. The most common and simple way of protecting a network resource is by assigning it a unique name and a conforming password. Network security is simply a process accepted to detect and prevent unapproved custom of your computer. In other words, network security is a technique in the form of software, which protect the primary networking structure from illegal access, breakdown, misuse, damage, alteration, or unsuitable discovery. When developing a secure network, the following need
Networking is part of our everyday lives now. Weather is us using our phones, computer, using GPS for directions, watching 3D movies and TV’s or in our work environments. Network Security has become search a big issue since our day to day live started to be more involve with us. These problems involve in all type of shapes and forms where some of these issues are cyber attacks, physical attacks, or abuse of policies. People are really exposed due to the amount of internet activities we have going on in most of our networks. There are two fundamentally different when it comes to networking, the data networks and the synchronous network comprised of switches. With that being said there are also
The framework of security policy is defined to construct a structure by the help of which policy gaps can be identified in an easy manner. A system specific policy would assist to ensure that all employees and management comply with the policies. This is also used to maintain the confidentiality for user authentication would assist in the confidentiality aspect of security, maintain integrity (There are several limiting rules or constraints which are distinct in the relational data model and whose work is to maintain the data’s accuracy and maintain its integrity.), availability and authenticity of the system. Access controls are a collection of mechanisms that work together to create security architecture to protect the assets of an information system. One of the goals of access control is personal accountability, which is the mechanism that proves someone performed a computer activity at a specific point in time. So, the framework acts as the guideline
In shaping a new security policies, it is essential to have a full understanding of all aspects of the internal network and services to be protected from both internal and outside threats. An article by Solms & Solms (2004) outlines several criteria in developing information security. First, a governing body must be formed to ensure all sensitive data is secured and provide due
Some network security concerns that should be addressed is the physical component while damage can be inflicted on the network from remote terminal, an attacker with physical access is a much greater concern. The Global Accounting network system should be placed in a secure room where only essential personnel have access. Network devices such as the modem and router should be password protected
Security is the degree of resistance to, or protection from, harm. It applies to any asset, such as a person, dwelling, community, item, nation, or organization. Information held on your IT systems is vitally important. Its availability, integrity and confidentiality may be critical for the continued success of your business. Security can be breached in several ways, e.g. by system failure, theft, inappropriate usage, unauthorised access or computer viruses. This will lead to the loss of sensitive or critical information, directly affect your competitiveness and cash flow, also damage your reputation.

Firewalls prevent unauthorized users from accessing a private network when it is linked to the Internet. Intrusion detection systems monitor private networks from suspicious network traffic and attempts to access corporate systems. Passwords, tokens, smart cards, and biometric authentication are used to authenticate system users. Antivirus software checks computer systems for infections by viruses and worms and often eliminates the malicious software, while antispyware software combats intrusive and harmful spyware programs (Laudon and Laudon, 2009, p.260)
Network Security Issues – major threats and the means to fight them Network security issues are the top priority of all who want to protect their data.
Security is a fundamental aspect of any network infrastructure. The goal is to always have the most up to date programs and protocols to ensure the protection of the network. No aspect is too small to over look. That could mean the difference between a secure network and a compromised network. The best way to achieve this is to break down every level and approach each one as a separate entity and secure it. Then you can modify it to suit the needs of your network.
Network Policies for disclosure or transmission of sensitive information; the ability to safeguard information depends on implementing and strengthening policies and procedures that enable network monitoring and detection of atypical actions to identify insider threats and intrusions.
With the increasing use of technology today with computers, there are better ways we can came up with to stop vulnerabilities in a network. As organizations increase their reliance on, possibly distributed, information systems for daily business, they become more vulnerable to security breaches even as they gain productivity and efficiency advantages. Network security is the becoming more important to a business because of the networks and applications. You never know when someone is coming for your business system. Looking at every strategy you have going on for your business. Need to have the set of tools for the security walls to be high. When dealing with hackers or competition all servers not to be access easily. There is a large amount
Network security has changed significantly over the past years. There is more and more data to monitor and analyze in order to detect the activity of your data and systems. Securing a network has many variables. Password authentication, network access, patches, anti-virus protection, intrusion detection, firewall and network monitoring tools are just a few of the things you can do to protect yourself.
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).
First and foremost it is most important to explain how network security works. There are three general types of security controls. These consist of administrative, physical, and technical controls. Administrative controls pertain to how your business has compiled security agreements and how new technology implementation should occur. Physical security, is exactly what it sounds like, physical aspects. This might include locks on doors where servers are located, fences around facilities where important information is stored or any other control measure that would physically delay an attacker from being able to reach a network. Technical controls consist of what an IT staff implements within the network to decrease the risk of a breach. Examples of this include encryption, configurations, and layered security. It takes a combination of all
According to Kizza (2013), the rapid growth of networking has led to increased security risks. Many of these risks are as result of hacking, improper uses of network resources and network device vulnerabilities. Awareness of the various weaknesses and vulnerabilities is vital to the success of current networks (Kizza, 2013).
