...Earnest MGMT447-02: Technology Management 31 October 2012 Abstract In this presentation, the processes of risk assessment, risk identification, and risk control strategies will be explained. Examples of some of the risk control strategies that are available for companies are cited along with possible ways to utilize these tools to create a company risk policy. Also included are explanations of control types, how they are used and implemented, and the risk they are intended to minimize. Unit 5 Individual Project: Risk Control Strategies Risk Management is a discipline employed by organizations for the express purpose of minimizing threats to the company’s security assets. Risk management also works to support managers and increase their confidence when making decisions. Security risk plans are used to help management develop coherent and comprehensive strategies for managing risk prevention. An important part of a security risk plan is evaluating the level and type of countermeasures needed to guard against security threats capable of causing security breaches (Stoneburner, Goguen, & Feringa, 2002). The security management process can be described in four steps: I. Identify security risks. II. Develop strategic countermeasure plans. III. Implement strategies. IV. Monitor, evaluate, and maintain appropriate security measures. Areas of Risk Management A threat is defined as a situation where a threat-source has the potential to......

Network Access Control: User and Device Authentication

...Enterprise Security Network Access Control: User and Device Authentication August 2005 Intel IT is piloting new security methods to provide network access control by authenticating devices as well as users. Since networking has evolved to support both wired and wireless access, securing corporate networks from attack has become ever more essential. Therefore, to effectively enforce network access control policies in a proactive manner, we are developing a method to authenticate users and devices before they connect to the network. Network Access Control at Intel • Over 90,000 employees worldwide • 80 percent of knowledge workers are mobile and unwired • Over 50,000 remote access users Background As a global corporation, Intel IT supports more than 90,000 employees and contractors all over the world, and 80 percent of our knowledge workers are mobile and unwired. Network access depends more and more upon wireless LANs and WANs, as well as virtual private network (VPN) remote access. All of these technologies have the potential to open our network perimeter to threats. When we considered the threat of viruses and worms, it was evident that we needed additional controls to secure the enterprise network and its information assets from unauthorized devices and unauthorized people. Figure 1 shows how we could authenticate devices and users as part of the authentication pyramid. Figure 1. Authentication pyramid Info Use Auditing Access Control User Device......

Layered Security Strategy for Ip Network Infrastructure

...Layered Security Strategy for an IP Network Infrastructure Lab Assessment Questions & Answers 1. Explain why a layered security strategy helps mitigate risk and threats both external and internal. Multiple layers can be used to secure internal threats like keeping employees from accessing inappropriate material, update and patch workstations and run current anti-virus/malware on workstations daily. The layers also help mitigate external threats like hackers by using firewalls and shutting traffic out of the internal network. 2. Why is it a good idea to put shared servers and services on a DMZ when both internal and external users need access? When you have a DMZ there are two firewalls to protect the internal network from external threats. The necessary servers can be placed between the two in order to allow access from either side through strict firewalls while still allowing very little external traffic into the internal zone. The outermost firewall can allow a certain set of traffic to come in and access the servers. The inner most firewall blocks access into the intranet while allowing internal users to access the information on the servers. 3. What recommendations do you have for the future e-commerce server and deployment in regards to physical location and back-end security for privacy data and credit card data? I would place the e-commerce server in the DMZ with the private and credit card data stored inside the internal network. The commerce......

Malicious acts bring up the important topic of disaster recovery. Companies must have up to date copies of their important documents and software to prevent extended downtime. The saved information will let the company's employees continue to work while the IT department deals the damaged media. Hacking Into a Website Some being able to hack into a person’s web site is never going to be justifiable. A hacker is someone who illegally gets a hold to personal and private information in a computer system. This person then tampers with the information and start to cause problems.

Comparing Cost Control Strategies

...Comparing Cost Control Strategies Kristy Barbeau HCR/230 Wednesday January 22, 2014 Beth Schalm Comparing Cost Control Strategies Employer sponsored insurance falls under what is called group health plans. When an employee has this coverage the group are the ones that are the policyholders. The health care plans are negotiated through the human resources department and they select what plans to offer the employee. Most plans are the basic plans and that is where the riders come in. what riders mean is it gives the employee the option to choose what health care plan they want to choose. These options may include vision and dental add-ons. Another rider could be services such as massages, nutrition counseling, and possible vitamin supplements. Some insurance plans would not cover these things. It just depends on the plan that is chosen. An employer may also choose the Federal Employee Health Benefits Program (FEHB), which happens to be the largest health care program that the employers use. However, the government controls this plan. This is the plan they use for the government workers, people who retired from the government, and their families. Another plan that employers use is the Self-Funded Health Plans. This is for many large companies to ensure the cost of the employees’ medical benefits come from them rather than buying them from different insurance companies. This plan is basically a self-insured plan but the employer sets the level of benefits the employee......

Network Access Control

...Network Access Control (NAC) is a computer networking solution that uses a set of protocols to define and implement a policy that describes how to secure access to network nodes by devices when they initially attempt to access the network.[citation needed] NAC might integrate the automatic remediation process (fixing non-compliant nodes before allowing access) into the network systems, allowing the network infrastructure such as routers, switches and firewalls to work together with back office servers and end user computing equipment to ensure the information system is operating securely before interoperability is allowed. A basic form of NAC is the 802.1X standard. Network Access Control aims to do exactly what the name implies—control access to a network with policies, including pre-admission endpoint security policy checks and post-admission controls over where users and devices can go on a network and what they can do. In plain English[edit] When a computer connects to a computer network, it is not permitted to access anything unless it complies with a business defined policy; including anti-virus protection level, system update level and configuration. While the computer is being checked by a pre-installed software agent, it can only access resources that can remediate (resolve or update) any issues. Once the policy is met, the computer is able to access network resources and the Internet, within the policies defined within the NAC system. NAC is mainly used......

Basically we can divide such distributed processing into 3 primary categories. They are: ➢ Terminal-to-host processing: With terminal-to-host processing the application and database resides on the host computer. The users interact with the applications with “dumb” terminals. ➢ File server processing: With file server processing the application and database reside on the host computer, called the file server. The database management system runs on the user’s PC. When the user needs data from the file server. The file server sends to the user the entire file with the data requested. The downloaded data can be analyzed and manipulated on the user’s PC. ➢ Client/server architecture and processing: Client/server architecture links two or more computers in an arrangement in which some machines perform computing functions for end-user PC’s. Sometime either machine can perform processing and......

Keiretsu Network Strategy

...Investor Group A as well as multiple supply chain strategies it is recommended that a Keiretsu network is implemented. By employing the Keiretsu network strategy the group of investors not only owns the production facility but also have the opportunity to invest in and/or own suppliers to ensure the lowest costs. The Keiretsu network is the best choice for Investor group A because it is part collaboration part purchasing from a few suppliers and part vertical integration. It combines the benefits of using few suppliers such as suppliers having a large commitment to the buyer and more likely to have a better understanding of the broad objectives of the manufacturer and the end consumer. The Keiretsu network provides an assured price structure, predictable inventory and delivery schedules as well as clear quality and performance standards. A stable environment such as this close cooperation between the supplier and the manufacturer can lead to quality improvements, continual product development and reductions in cost. As stated before vertical integration is a component of the keiretsu network, with vertical integration the manufacturer has the ability to produce supplies that were previously purchased or to actually buy a supplier. Advantages of this would be inventory reduction and scheduling, cost reductions, and adherence to quality standards. The strategy of using many suppliers and playing them against one another is a strategy that is best used when the products......
