Preventing Attacks on New Network-Based Systems

We have been engaged in business for some time, and have been very successful, however we need to re-examine our network configuration and infrastructure and identify that our network defenses are still reliable, before we make any changes. We need to take a hard look at our current configuration of host, services and our protocols within our organization. Data from a large number of penetration tests in recent years show most corporate networks share common vulnerabilities. Many of these

This is an open exposure due to the uncertainties of the internet. Controlling access to information systems and associated networks is necessary for the preservation of their confidentiality, integrity, and availability. Confidentiality assures that the information is not disclosed to unauthorized persons or processes. Any automated attacks or personal attack or attack to exploit the company secrets/statistics/data is the biggest threat to that may occur without the firewall.

Technological advances in data storage, information systems, the internet, and other forms of communication continue at a rapid pace. The centralization of its IT systems and administrative procedures achieves further savings.

Navy/Marine Corps Intranet (NMCI) program was basically designed for replacing the dozens of the Navy as well as Marine Corporation’s computer networks into a centralized managed setup through a single conductor. The main objective was to make an intranet that is secure, centralized, as well as foster universal access to integrated data, voice, and video communication; removal of any kind of network impediments; increase productivity, and elimination of interoperability issues. For the purpose, contract based on performance was signed with Electronic Data Systems Corporation (EDS). The initial cost of the project was estimated at $6.9 billion. The NMCI project performance was not as expected as it was found that NMCI has met only 3 of the pre-defined 20 performance targets. To get insight into the reasons of

The use of an intranet in organizations has been proven to enhance communication and access to information, and they are used to achieve organization goals and innovation. Intranets have

Databases help people reduce time for us by needing to gather all information, processing, and interpreting data manually. For this we can use the Microsoft Access Program or FileMaker Pro. The process component is for generating any useful information for decision making. It includes any for transaction processing in which the banks use to make transactions for any deposits, withdrawals, payments, cashiers checks, or money orders. For example, anytime there are transactions being recorded in the computer, it will appear in the journal and will be printed for the end of the shift of the day once a teller balances out and closes for the day. The information component is the output of the information systems. For example, information contains qualities such as the timeliness and the integration of other data & information. The personnel information system provides useful information to carry out any objectives effective for those decision makers. For example, intranets is useful for providing basic human resources functions such as checking the paid time off left or by searching for their 401k plan retirement of their funds. The intranet is a network that provides for the protocols and technologies to collect, store, and disseminate any info that correspond to business activities. For example, anything regarding a sale, customer service, hr, and marketing. The logistics information is to reduce the prices of transportation

As a business grows, it might expand to multiple offices across the country and around the world. For a growing business firm, limited number of offices is typically not adequate. With adequate capital and personnel, many business firms desire to set up multiple offices to attract different areas of customers (Lock, 2007). To keep business running efficiently, the employees working in those locations need a reliable, secure and fast way to share information across computer networks. With the help of networking technology, one firm can install a network so that all the employees and customers of separate offices can communicate, and access

These developments, along with many others, are changing the nature of management. A networked company is a different kind of company, but most managers do not yet appreciate the difference.

Sometimes, resolving much vulnerability may harm the system. For example, dealing with the vulnerabilities like a weak SQL server administrator password, a Windows OS configuration, and a server hosted on a wireless network might not be a major security issue separately. But, resolving all vulnerabilities simultaneously can prove to be dangerous for computer system.

DEWAR Chemical Company is a new startup company with 100 employees. Twenty of those employees will be assigned to the information technology (IT) department. The CIO, which is also included in the twenty employees assigned to the IT department, has been tasked by the CEO to implement a secure information technology environment to include the creation of a network infrastructure, disaster recovery, enterprise resource planning (ERP) system, track regulatory information in reference to the products sold, storing and backing up the data, and have the ability to accept credit card payments. In this IT system, the company will be enable to take of broadband internet access an increasing efficient option involves remote access support, while solving IT issues over the phone and provide remote support of enrolled for the service. Furthermore, they will have technical support to troubleshoot IT related issues such as install/re-install software, configure and install hardware and networking equipment and set-up new PC's (IT Support Services, 2012).

Networks have become a vital part of almost every organization changing the way that business is conducted from day to day. In the early days of the computer era business men and women have had to use standalone machines that were partially interconnected or not interconnected at all. Since then computing has gone through various changes through a number of decades which has led to the complete integration of various computing devices and now professionals are able to share hardware and software resources without difficult which has led to the reduction of business costs and a higher level of productivity. For example instead of having to buy a printer for every department or office, an organization can simply use one networked printer which everyone in the organization has complete access to. Another cost reduction example is the ability for an organization to install software such as Microsoft project on a server and therefore, enabling every one that has access to the server to use the resource. This saves the organization expenses as they don’t have to buy separate licenses for every user’s computer.

As a distributed system with a number of nodes working together, a Big data cluster relies on the interconnect to communicate between Data Nodes and Name Nodes. The system also needs to extract data from data sources via the network. Thus, the security of the network is critical to the Big data system. The threats relevant to the network include DNS spoofing, eavesdropping attack and Denial-of-Service attacks, Man-In-the-Middle attacks, etc.

The world is constantly changing especially in technology. Each day new software and hardware is created to accomplish tasks that were not possible before. These new software’s and hardware’s offers new problems to come with these new accomplishments. Businesses are constantly looking for ways to make their employees more efficient. Allowing employees to communicate not just in the office, but remotely is being a requirement at this day and time.

The new system provides the employees with the ability to use internal applications and most functions. This means that the system will help to improve time and cost efficiency and access to the information. In other words, it will help to improve employee’s productivity and the company’s high level of flexibility.

When discussing Network security, it is not much different then home, business, work, and personal security. Sometimes they are used together in ways to protect the safety of lives and important information on documents or files that are personal or proprietary. In the past before the age of computers and most importantly a network and internet, most people used security alarms, security guards, safes and locks to protect. With this day and age, the technology being used has been transformed in to the digital future. Information systems are the overall aspect of computer technology for home and business. The methods used to attack and protect a computer or network from vulnerabilities or threats will be discussed. Some of the findings that can be associated with the security do to vulnerabilities will be identified. The studies dealing with the subjects and participants that have been conducted will also be annotated. The implications associated with these vulnerabilities, threats, and attacks will show findings of policies, technology, and countermeasures put forth to detect, deter, or stop them. The conclusions will draw forth all the findings and results that were found during the research of this paper.
