Novell Network for Company Security
As today's businesses increase in sizes, there is a more demanding need for an increase in security needs. Many businesses today have to answer the question of, "When do I know that have too much security and which network system is more secure for my company?" To answer this question many points of views have to immerge with the best compatible solution. Companies should consider involving many systems such as cost management, and security management system. Companies don't want to have too much security when the solution cost more than the problem in money or time. Under these aspects if companies want to start a new system, which I'm considering here two major operating systems such as Windows NT, and Linux by give them close look for how they are operating and what are they using in their security system to insure businesses and companies securities and how are they reducing security threats.
The concerns about security of an organization is not directly depend on the data communication related areas but also the control mechanism which implements, restricts and protects the threats from in and out side the organization. In our age of decaying morals, we find the need for security in every aspect of life. There are far to many people that are willing and able to take anything they can that doesn't belong to them. We have security everywhere we look. There are armed guards in our stores and even schools. Police officers patrol the streets trying to keep people safe. We have people to provide security in a world where things are physical, but what to we do in a computer world, where what we want to keep safe is information? This is where computer security comes into play...

PKC is the enabling technology for all Internet security and the increasing use of digital signatures, which are replacing traditional signatures in many contexts. However, RSA is better than PKC because RSA doesn’t need digital signature. As a result, the RSA algorithm turned out to be a perfect fit for the implementation of a practical public security system. In 1977, Martin Gardner first introduced the RSA system. After 5 years, company RSA used secure electronic security products. Nowadays many credit companies of all over the world use the RSA system or a similar system based on the RSA system.
The RSA cryptosystem, imagined by Ron Rivest, Adi Shamir, and Len Adleman , was pitched in the August 1977 issue of Scientic American. The cryptosystem is generally ordinarily utilized for giving security and guaranteeing legitimacy of advanced information. Nowadays RSA is sent in numerous business frameworks. It is utilized by web servers and programs to secure web traffic, it is used to guarantee security and legitimacy of Email, it is utilized to secure remote login sessions, and it is at the heart of electronic Visa installment frameworks. In short, RSA is much of the time utilized within provisions where security of advanced information is a worry.
Security helps the organization meet its business objectives or mission by protecting its physical and financial resources, reputation, legal position, employees, and other tangible and intangible assets through the selection and application of appropriate safeguards. Businesses should establish roles and responsibilities of all personnel and staff members. However, a Chief Information Officer should be appointed to direct an organization’s day to day management of information assets. Supporting roles are performed by the service providers and include systems operations, whose personnel design and operate the computer systems. Each team member must be held accountable in ensuring all of the rules and policies are being followed, as well as, understanding their roles, responsibilities and functions. Organizations information processing systems are vulnerable to many threats that can inflict various types of damage that can result in significant losses (Harris, 2014). Losses can come from actions from trusted employees that defraud the system, outside hackers, or from careless data entry. The major threat to information protection is error and omissions that data entry personnel, users, system operators and programmers make. To better protect business information resources, organizations should conduct a risk analysis to see what
Digital world is dangerous because it is silent. Feeling secured is more dangerous because it makes the organization complacent. Hence, every organization should keep taking measures towards strengthening its security on an ongoing basis. This is possible by moving on to the next security level and embracing the new security techniques. After all, a stitch in time saves nine.
As the internet is becoming faster and faster, an operating system (OS) is needed to manage the data in computers. An Operating system can be considered to be a set of programed codes that are created to control hardware such as computers. In 1985 Windows was established as an operating system and a year earlier Mac OS was established, and they have dominated the market of the computer programs since that time. Although, many companies have provided other operating systems, most users still prefer Mac as the most secured system and windows as it provides more multiple functions. This essay will demonstrate the differences between windows
Cisco Systems, Inc. is a leader in networking for the internet, they develop hardware, software, and services to help create internet solutions that make internet networks possible. Cisco was founded in 1984 by a small group of computer scientists from Stanford University. They are a worldwide company with headquarters in: San Jose, California, Amsterdam Netherlands, and Singapore. Currently, they employ approximately 74,000 people throughout the world. Cisco operates on a set of values which include: change the world, intensely focus on customers, make innovation happen, win together, respect and care for each other, and always do the right thing. They show these values through global involvement in education, community, and philanthropic efforts. (Cisco, 2004)
My knowledge has grown over the past six years, outwith the areas of learning offered by school courses, and I see this course as an opportunity to gain new skills and broaden my knowledge further. My main interests are varied, including communications and the internet, system analysis and design, software development, processors and low level machine studies. I have recently developed an interest in data encryption, hence my active participation in the RSA RC64 Secret-Key challenge, the latest international de-encryption contest from the RSA laboratories of America.
Organizations which rely on network infrastructure for their business operation must utilize security technology to protect the network from harmful actions of automated attacks as well as malicious human activity. It is also important to enact policies and guidelines for the employees of the organization, which in many regards can be the weakest link in the chain of security. According to a survey by The Ponemon Institute (2012), “78 percent of respondents said their organizations have experienced a data breach as a result of negligent or malicious employees or other insiders” (p.1). A statistic like this points to the need for comprehensive policies that detail the company’s expectations and mandates for specific situations relating to cybersecurity.
Computers; they are a part of or in millions of homes; they are an intricate part of just about every if not all successful businesses, the government, and the military. Computers have become common place in today’s society and the lives of the people who live in it. They have crossed every national, racial, cultural, educational, and financial barrier, which consequently ushered in the information age. A computer is a programmable electronic device that can store, retrieve and process data, and they come in all shapes, and sizes. They can be used for and in just about anything. As stated before, they are used in just about every aspect of modern society. They are so fundamental to modern society that it would be disastrous to society without them. As stated before, there are many areas in modern society that are run by computers. They play an intricate part of millions of homes in the world. Office workers in business, government and the military may use them to write letters, keep rosters, create budgets, find information, manage projects, communicate with workers, and so on. They are used in education, medicine, music, law enforcement, and unfortunately crime. Because computers have become such a part of the world and how it operates, there is a tremendous responsibility for those who are in control of these computers and the vital information that they carry, to manage and protect them properly. This is management and protection is vital because any loss or damage could be disastrous for the affected entity. For example, a mistake or intentional alteration of a personal credit file could affect ones ability to buy a car or home, or can lead to legal actions against the affected person until the mistake or intentional alteration has been corrected. Therefore, with the advent of computers in the information age, and all of the intentional and unintentional violations against them, comes the need to safeguard them and the information they carry with strong systems and policies of computer security.
In a company, a senior management needs to address management tasks and have an information security governance. The information security governance (ISG) is a way for a company to protect information in the information systems. According to Grama, the responsibility of the ISG falls on the executive management team to protect the information assets, (p. 373, 2011). The company will need to have its information security goals align with its business needs to help protect information. For example, a company needs to make a profit to stay in business and it should include goals to protect information from hackers. If a company gets a reputation of having security breaches, people would not want to do business with the company and they would lose profits. The CIA triad of confidentiality, integrity, and availability can be used by the ISG to meet the goals. Confidentiality is to protect information by allowing the correct people to have the permissions to access and use information. Integrity makes for the information is accurate and changes cannot be made to the information without the correct permission. Availability is making sure the information systems are always up and that information can be accessed. There are many tasks that senior management needs to address such as to make sure everyone understands the needs for the security of information to be governed. This can be done by informing the board and other senior management who may not be as familiar with information systems, how the threats and damage form the threats can disrupt operations and profits in the company. Another task for senior management to help with the development of the security framework by creating policies, standards, procedures, and guidelines. Thes...
...re to unauthorized individuals or system. For example, credit card information or bank account number of a client in a bank should not be exposed to unauthorized people. The data can be encrypting confidentially by hiding plain text data. Other than that, data should be protected from deletion or modification by unauthorized users in an organization. This is because any changes may cause unrevealed damage to the organization. Data integrity can only be achieved by hashing mechanism. Availability of data accessibility in an organization should be guaranteed by backup system or network hardening mechanisms. All the systems, channels, and mechanism should be working properly to ensure the information needed is always available. Highly available networks are designed to manage multiple network connection and deal with potential problems such as denial of service attack.
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

Nowadays, the information is the most treasured asset in an organization, due to it along with the experience represents the input necessary to take appropriate decisions and consequently to have success in the business. Almost all the information and knowledge related with the processes business, goods and services offered by a company, is processed, managed and stored through technology and information systems, thus the security of information has become increasingly important and plays a critical role in the enterprise government.
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.
