What does an assessor need to understand before she or he can perform an assessment? How active is each threat agent? How might a successful attack serve a particular threat agent’s goals? This assignment should be in APA format and have to include at least two references.

What is the upper limit to the data rate the channel can carry,i.e., what is the theoretical maximum channel capacity ? In practice, assume we choose a data rate of 2/3 the maximum theoretical limit. how many signal levels are needed to achieve this data rate?

Respond to the following in a minimum of 175 words:  Locate and review tutorial help on Microsoft® Excel® on the Microsoft® Office website. Discuss the question: What Microsoft® Excel® features make the software such an important and popular tool for business professionals?

In this discussion question, you have the opportunity to be creative and to relate what you have learned to your professional lives. Please explore and critically think about some of the learning objectives and concepts presented in this course. Please effectively communicate how you would lead an organization (or a group of people within the organization) by applying the knowledge you have learned ethically and responsibly. Your discussion should also include innovative thinking, and information-technology aspects (such as the Internet, social media, computers, etc.) that may assist you in decision-making. You may frame your discussion around any functional component of business, and in any context; problem-solving, management, leadership, organizational behavior, etc.

Many systems in organizations especially the service organizations are moving to a real time system – where data is captured on a real time basis. For example, traffic light/signal data are recorded continuously (actually triggered by an event) and when a driver disobeys the light, the data is recorded and then used to send tickets to the driver with a link in the ticket for a video clip of the incident where the traffic law was broken. In 80 words or more what other real time systems that are important to organizations?

Many people believe that the use of biometrics is an invasion of privacy. For example, an eye scanning device records the inner structure of a person’s eye and stores that image in a database. Critics worry that databases of human traits used to maintain corporate security may actually pose a privacy threat to individuals if such data were used in other ways. In your view, are such concerns justified? Why or why not? (2-Paragraphs. Some common biometric techniques include: Fingerprint recognition, Signature dynamics, Iris scanning, Retina scanning, Voice prints, Face recognition. Select one of these biometric techniques and explain the benefits and the vulnerabilities associated with that method in 2-3 paragraphs.

1. Describe the importance of databases and database management systems in managing organizational data and information 2. provide the types and some examples of database management systems 3. address the advantages and disadvantages of using a DBMS.

Switching is practically invisible (and occurs at layer 2 of the OSI model) and generally not an issue unless you want to create a VLAN or alter the flow of data traffic for some reason. But hey, we gotta cover it because it’s a part of networking, and the switch has greatly improved networking speeds. Also, because there really isn’t much to switching (there shouldn’t be for an IT professional) we squeeze in protocols this week! search for some major switch manufacturers and find the differences between models. Select several models depending on where they go in your project. o Hint – You don’t want to pay for a 24-port Gigabit switch if a room only has two computers that are used for browsing purposes! Similarly, you don’t want to put a 4-port switch in a room that is expected to be turned into a computer lab. Include some expandability into the project, but be realistic. For your task, submit a list of protocols that would be running on your project network, and if you decided to change the ports, please specify.

Project Part 3: Malware Protection Procedure GuideScenarioAlways Fresh allows external users, such as vendors and business partners, to access the Always Fresh Windows environment. You have noticed a marked increase in malware activity in the test environment that seems to originate from external users. After researching the likely source of new malware, you conclude that allowing external users to connect to your environment using compromised computers exposes Always Fresh to malware vulnerabilities. After consulting with your manager, you are asked to create a policy that will ensure all external computers that connect to the Always Fresh environment are malware-free. You create the following policy: “To protect the Always Fresh computing environment from the introduction of malware of any type from external sources, all external computers and devices must demonstrate that they are malware-free prior to establishing a connection to any Always Fresh resource.”Consider the following questions:1. What does “malware-free” mean? 2. How can a user demonstrate that their computer or device is malware-free? 3. What are the steps necessary to establish a malware-free computer or device? 4. How should Always Fresh verify that a client computer or device is compliant?TasksCreate a malware protection procedure guide that includes steps for installing and running anti-malware software. Fill in the following details to develop your procedure guide:1. Provide a list of approved anti-malware software solutions—include at least three leading antivirus and two anti-spyware products. You may include Microsoft products and third-party products. Instruct users to select one antivirus and one anti-spyware product and install them on their computer.2. Describe the process of a. Ensuring anti-malware software and data is up to date. Mandate daily updates.b. Running regular malware scans. Mandate that automatic scans occur whenever the computer is idle. If that setting is unavailable, mandate daily fast scans and biweekly complete scans.3. Provide steps to follow any time malware is detected.a. Immediate reaction—what to do with current work, leave the computer on or turn it off b. Who to contact c. What information to collect The procedure guide may be used by company security professionals in the future. Hence, all steps listed should be clear and self-explanatory.
