Make presence in a building or area a policy in accessing network resources by integrating physical and network access through the Trusted Computing Group's IF-MAP communications standard.

Networking and cyber security are deeply intertwined. A well-designed network incorporates security measures at every layer to protect data integrity and availability. Here are ways to integrate networking and cyber security effectively:

The biggest threat to network security is underestimating the threat to network security. And as IP networks become the defector standard, ignoring this reality can extract a heavy price down the road.

Network security involves protecting networks from unauthorized access and risks. It is important for network administrators to take preventive measures to secure networks used by individuals, businesses, and governments. There are various types of network security devices that fulfill different functions like blocking surplus traffic (active devices), identifying unwanted traffic (passive devices), and scanning for potential problems (preventative devices). Firewalls are a key example of an active device that establishes a barrier between internal and external networks and regulates incoming and outgoing traffic.

This document discusses security issues in grid computing and proposes an enhanced amalgam encryption approach. It begins with an overview of distributed, cloud, and grid computing. Grid computing involves coordinating shared resources across distributed, heterogeneous environments. Major security issues in grid computing include integration with existing security systems, interoperability across domains, and establishing trust relationships. The document then discusses cryptography approaches used to provide security, including symmetric and asymmetric encryption. It proposes a hybrid encryption solution combining AES and RC4 algorithms to address overhead limitations of previous approaches for large distributed networks like smart grids.

This document summarizes a research paper that proposes a security architecture for cloud computing that dynamically configures cryptographic algorithms and keys based on security policies and inputs like network access risk and data sensitivity. The architecture aims to improve security while reducing costs by only using the necessary level of encryption for each situation. It describes using the Blowfish algorithm instead of AES and adjusting the key size from 128 to 448 bits depending on factors like network type and data size. Results show Blowfish has better performance than AES, especially with larger keys on larger amounts of data. The goal is to provide flexible, efficient security tailored to each user's needs.

Network security architecture is the planning and design of the campus network to reduce security risks in accordance with the institution’s risk analysis and security policies. It focuses on reduc-ing security risks and enforcing policy through the design and con-figuration of firewalls, routers, and other network equipment. Network security is important because it is one of the means to enforce the policies and procedures developed by the institution to protect information. It is often referred to as the “front door” in broader discussions of IT security. To the extent that you can block network access to a computer, you “lock” the door and provide bet-ter protection for that computer and its contents. Traditional network design has focused on creating a secure net-work perimeter around the organization and strategically placing a firewall at the point where the network is connected to the Inter-net. For higher education, this traditional design is problematic; our constituents need access from off campus to a large number of machines and services on campus. In addition, because we have many computers on our campus that we cannot implicitly trust, we also must be concerned about security threats from inside the perimeter protected by a traditional firewall. These design issues require a different approach to network security. Although it is impossible to do justice to the topic of network design in a few pages, there are some best practices that I feel universities should focus on in terms of network design. Step 1: Eliminate Network Components That Still UseShared Ethernet Shared Ethernet switches (or hubs) were developed more than a decade ago to interconnect multiple computers and networks. These hubs retransmit all network traffic to all computers connected to that hub. The security implication is that if one computer has its security compromised it can be used to monitor network traffic com-ing from any other computer that shares the same hub. This could expose passwords and other sensitive information. Today, switched Ethernet, which isolates traffic intended for one computer from the view of others on the same switch, is very inexpensive and, hence, it is worth the cost of replacing older hubs. Step 2: Embrace and Implement the Concept of Defense and Use Multiple Firewalls Within Your Network Commercial and Linux-based firewalls are inexpensive enough that you can deploy these in multiple locations as needed. It is still bene-ficial to have a firewall separating your institutional network from the connection to the Internet. This firewall, called a border firewall, will provide a minimal level of protection for all computers on your net-work. The major benefit of this firewall is that it allows your network and security staff to quickly block external access should a threat arise, such as when the “SQL worm” was launched in January 2003 In addition to the border firewall, consider adding internal firewalls to protect areas that requi.

The document discusses various aspects of securing e-commerce networks. It describes digital certificates which serve to verify identity and are issued by a certification authority. There are four main types of digital certificates. The document also discusses selecting network security technologies based on principles like defense in depth. Technologies discussed for securing networks and protocols include firewalls, intrusion detection systems, virtual private networks, secure sockets layer (SSL), secure hypertext transfer protocol (HTTPS), and public key infrastructure.

Each packet is examined separately. Bridge – A network device that separates traffic into separate collision domains at the data layer of the OSI model. Cloud computing – The automatic provisioning of on demand computational resources across a network. Coaxial cable – A network cable that consists of a solid center core conductor and a physical spacer to the outer conductor which is wrapped around it. Commonly used in video systems. Collision domain – An area of shared traffic in a network where packets from different conversations can collide. Concentrator – A device used to manage multiple similar networking operations, such as provide a VPN endpoint for multiple VPNs. Data loss prevention (DLP) – Technology, processes, and procedures designed to detect when unauthorized removal of data from a system occurs. DLP is typically active, preventing the loss of data, either by blocking the transfer or dropping the connection. Firewall – A network device used to segregate traffic based on rules. Hypervisor - A low-level program that allows multiple operating systems to run concurrently on a single host computer. Hub – A network device used to connect devices at the physical layer of the OSI model.

Internet content filters – A content-filtering system use to protect corporations from employees’ viewing of inappropriate or illegal content at the workplace.

The document discusses security measures taken by the ICT directorate of Addis Ababa Science and Technology University. They use a FortiGate 1200D firewall to secure their internal network and servers from threats. They also use Kaspersky antivirus software, implement backup and fault tolerance systems, and take steps to secure their web, database, and mail servers. The staff follow security checklists that include keeping systems updated, implementing firewalls and SSL, encrypting connections, securing user logins and databases, and scanning for malware.

This document discusses security challenges in ubiquitous computing environments. It begins by defining ubiquitous computing as involving the integration of computing technology into everyday objects and environments. This allows information access from any device at any time, but also increases security risks. The document then outlines some common ubiquitous applications like smart homes. It identifies key security issues like lack of authentication, unauthorized access, and privacy concerns. Finally, it discusses challenges in ubiquitous security including how the expanded computing environment impacts traditional security methods and introduces new privacy and trust issues.

This document discusses network security standards organizations like NIST and ISO, as well as key security concepts like threats, attacks, security services, and security mechanisms. It provides examples of cryptographic techniques like symmetric and public key encryption. It also summarizes standards for wireless security under IEEE 802.11i and the use of firewalls to filter network traffic and protect sites.

Internet Protocol Security (IP Security) is a security protocol that serves to secure information in the event of an exchange on the internet. It happens if there is a connection between private IP and public IP. This protocol will exchange packets on the IP layer safely. It provides two types of encryption options, transport, and tunnel. Transport mode will encrypt the data section without changing the packet header. The algorithm used to encrypt data is a symmetric cryptography algorithm. This protocol authenticates and encrypts every packet from a data transmission session. Also, it can generate keys between the sender and the recipient at the first time it is activated and can negotiate the cryptographic keys that will be used during the session. IP Security is an end-to-end cryptosystem that works at the internet layer of the Internet Protocol Suite. The protocol serves to protect the data flow in host-to-host, network-to-network, and network-to-host as well.

This document discusses the cyber security risks of smart grids and proposes an integrated security framework to address these risks. Smart grids integrate information infrastructure with electrical infrastructure, improving performance but also increasing vulnerability to cyber attacks. The framework features security agents, managed security switches, and a security manager to provide layered protection, intrusion detection, and access control across the power automation network in a scalable and extensible manner. This integrated approach is needed as power systems have different security needs than traditional IT networks.

My work as a teacher and my students’ experiences in the learning spaces I help create sometimes reflect Coelho’s definition. In class, I often make the argument that language is the ultimate form of magic. Without it we don't really understand the world about us. It is that bridge between what is known and what wants to be known or is currently invisible. In our sessions, because most of my students are familiar with and culturally rooted in the Bible, I mention a passage where God tells Adam to name the animals in the Garden of Eden. For me, this story works as a powerful reminder that the impulse to name is an integral part of what it means to be human. The naming of the animals implies that the way we relate to the world has something to do wi.

I live with three younger siblings who do not fit that description. We live in the same house; they are American, loved, attending an amazing high school, privileged, but what is missing? The answer is the color of their skin; I am White and they are Black. My three youngest siblings are adopted from various parts of the United States as well as Africa, and their lives are worlds apart from mine; yet, we live feet apart. I am never afraid to walk home from school or get arrested by the cops, and yet I will be walking home with my 6’0, line man sized, African American little brother and people will cross to the other side of the street. Whole families have crossed in the middle of the road to avoid passing next to us. I know for a fact most of my friends do not worry about their little brother coming home safe because he has the build of the boys you hear about on television being beaten to death—because he has the skin color of the boys on television. The New York Times best seller, “The New Jim Crow: Mass Incarceration in the Age of Colorblindness” by Michelle Alexander works to give an explanation for the phenomenon that has been splashed across the news left and right. This movement is known as the “Black Lives Matter” movement that has the purpose of fighting back against the racism in our society: the human rights and dignity many people of color feel they are denied. There is a problem in our society that needs to be addressed because lives are on the line; and, I feel that the Black Lives Matter movement is not effectively or gracefully working to solve this problem as God intended. My purpose for this paper is to argue that our society is not seeing the new racism that is running rampant; that God did not intend for any sort of racism; and, finally conclude with our society should be called into action, especially the believers. For this paper, it will be broken up into three different sections: Michelle Alexander’s book, the corresponding Bible passages, and concluded with the application section. z Body (example) “The New Jim Crow: Mass Incarceration in the Age of Colorblindness” is a book by Michelle Alexander, whose main argument is “that mass incarceration is, metaphorically, the New Jim Crow.” Some background to explain this statement is Jim Crow laws were a set of laws that barred African Americans from ha.

This document discusses a reading from the book "Who Speaks for Justice, Part 5: Culture" and encourages critical reflection on culture. It prompts students to think about why cultural beliefs and behaviors exist, rather than just what they are or when they occur. Students are asked to consider what culture they practice, where it came from, how it impacts their own actions and thinking, and how it affects others. The reading suggests that cultural and social influences do not provide definite explanations for why societies are a certain way and calls for mindfulness of cultural norms and patterns of behavior.

Critical Reflection Exercise Students are expected to have completed the assigned readings each week and be prepared to comment critically. Rather than providing mere summaries of course readings, students will be asked to analyze and synthesize information from the assigned readings while reflecting on their own lived experiences using personal examples, situations they observe in organizations and within their communities, and current events. Students will submit a three page, double-spaced critical reflection of the assigned readings.  Assigned Readings: * For the Second Reading, just Chapter 1 & 2 .

Critical Reading Strategies The University of Minnesota published a guideline on critical reading, called Critical Reading Strategies.  Click here (Links to an external site.)Links to an external site. for the document. These guidelines suggest reading in an active and engaged way in order to analyze, evaluate, and understand texts. They recommend: 1. Identifying what you're reading for. Answer the following questions: 1. Why am I reading this text? Is it for general content? To complete a written assignment? To research information?  2. Allowing yourself enough time to read. I recommend giving yourself about one hour for every 25 pages of reading.  1. Note: Get comfortable with the feeling of struggling to read. Many of the texts we encounter this semester are very old. These readings may be obscure, difficult to understand, while reflecting cultural values that may be alien to you. I recommend paying attention to these feelings of discomfort as you read, and then using them to investigate the text further.  1. Example: You notice there is a lot of repetition in the Epic of Gilgamesh so you decide to look into it. You find out that the translation history of Epic of Gilgamesh involves a great deal of transcription from fragmented cuneiform tablets into our written text system.  3. Previewing the text. Does the text have any headings or sub-headings? If so, what are they? Does it include an introduction? If so, what does the introduction have to say? What does the text look like on the page? Literally--does it take up a lot of space? Bigger/smaller margins? Use block writing or stanzas?  4. Engaging. I cannot stress it enough: get in the habit of reading with a pen or pencil in hand. Write in the margins. Circle things you find important. Develop a notation system that reflects your thoughts or feelings as you read. 1.  You may draw an angry face next to the section where Gilgamesh insults the goddess Ishtar. You might underline the stanza in which Gilgamesh and Enkidu confront the monster, Humbaba. 2. What the texts says vs what it does. Take time to summarize the text says. What is the main idea? How is the main idea supported? Now ask yourself: how does it do that? Does it use imagery? Metaphor? Repetition? Simple or complicated language?  What is World Literature? David Damrosch is known for his extensive work in world literature and comparative literature. He is also the director of Harvard's The Institute for World Literature (Links to an external site.)Links to an external site.. In "Introduction: Goethe Coins a Phrase," Damrosch provides a brief history of world literature as a literary field, and also defines world literature in terms of translation and circulation. See below for the PDF. Damrosch, David (Introduction--Goethe Coins a Phrase).pdf · The concept of "world literature" as a literary field comes into the Western World through Goethe's term, weltliteratur. It's important to note that Goethe was not the first to use weltlite.

Critical Qualitative Research Design pages 70–76 Related to understanding your goals as a researcher is the development of the rationale of the study. A rationale is the reason or argument for why a study matters and why the approach is appropriate to the study. Rationales can range from improving your practice and the practice of colleagues (as in practitioner research), contributing to formal theory (e.g., where there may be a gap in or lack of research in an area), understanding existing research in a new context or with a new population, and/or contributing to the methodological literature and approach to an existing corpus of research in a specific area or field. Thinking about and answering the questions in Table 3.1 can aid in this process. Considering these kinds of questions is central to developing empirical studies, and it is important to understand that these rationales and goals will also lead you to conduct different types of research, guiding your many choices—from the theories used to frame the study to the selection of various methods to the actual research questions as well as designs chosen and implemented. There are many strategies for engaging in a structured inquiry process and through it an exploration of research goals and the overall rationale of a study. These strategies can include the writing of various kinds of memos, structured dialogic engagement processes, and reflective journaling. Across these strategies, creating the conditions and structures for regular dialogic engagement with a range of interlocutors is an absolutely vital and necessary part of refining your understanding of the goals and rationales for the research. We describe each of these strategies in the subsequent sections. Memos on Study Goals and Rationale Memos are important tools in qualitative research and tend to be written about a variety of different topics throughout the phases of a qualitative study. Memos are a way to capture and process, over time, your ongoing ideas and discoveries, challenges associated with fieldwork and design, and analytic sense-making. Depending on your research questions, memos can also become data sources for a study. There is no “wrong” way of writing memos, as their goal is to foster meaning making and serve as a chronicle of emerging learning and thinking. Memos tend to be informal and can be written in a variety of styles, including prose, bullet points, and/or outline form; they can include poetry, drawings, or other supporting imagery. The goals of memos are to help generate and clarify your thinking as well as to capture the development of your thinking, as a kind of phenomenological note taking that captures the meaning making of the researcher in real time and then provides data to refer back and consider the refinement of your thinking over time (Maxwell, 2013; Nakkula & Ravitch, 1998). While we find writing memos to be a useful and generative exercise, both when we write and share them in our indep.

Critical Infrastructures The U.S. Department of Homeland Security has identified what is determined to be critical infrastructure assets that are designated as potentially being of terrorist interest. Although the final responsibility and mission for protecting those assets and sectors of each remains with the DHS, the initial accountability rests with local ownership and authorities. The DHS has formulated a National Infrastructure Protection Plan to explain and describe the national responsibility. A very significant majority of the infrastructure elements are under private or corporate ownership and maintenance and must share the bulk of responsibility for protection and security under their own mission plans for security. Assignment Guidelines Address the following in 3–4 pages: What is the National Infrastructure Protection Plan (NIPP)? When was it created? Who created it? Why was it created? Explain. How important is the private sector with regard to critical infrastructure protection? Why? What types of strategies can be used for critical infrastructure protection (CIP)? What strengths currently exist in the United States with regard to CIP? Explain. What weaknesses still need to be addressed? Why? How can federal agencies effectively cooperate with private sector organizations? Explain. What types of information should be disseminated to private sector organizations that are responsible for key assets? Explain. What types of information, if any, should be withheld from the private sector? Why? ASSIGNMENT DUE TONIGHT 10/20/13 BY 12 CLOCK .

Critical Infrastructure Protection  Discussion Questions: How has the federal government responded to possible terrorist attacks (mitigation) where civil liberties have not been endangered? Considering that so much of the nation’s critical infrastructure is privately owned, how has the government-regulated possible civil liberties issues related to private sector employers/employees? Can a balanced policy be implemented regarding critical infrastructure without eroding privacy, freedom of information or other civil liberties? Minimum of 350 words APA Style with quotation and references .

Critical Infrastructures In terms of critical infrastructure and key resources (CIKR), an  asset  is a person, structure, facility, information, material, or a process that has value. For example, in the transportation sector, a bridge would be an asset. A  network  is a group of related components that interact with each other or share information to perform a function. For example, a light rail system that crosses multiple jurisdictions in a large metropolitan area would be considered a network. A  system  is any combination of facilities, personnel, equipment, procedures, and communications integrated for a specific purpose. For example, the U.S. interstate highways comprise a system within the transportation sector. A  sector  consists of a logical collection of interconnected assets, systems, or networks that provide a common function to society, the economy, or the government. For example, the transportation sector consists of vast, open, accessible, interconnected systems, which include the aviation, maritime, pipeline, highway, freight rail, and mass-transit systems. Address the following in 3–4 pages: For each of the 18 CIKR sectors, identify 1 – 2 local examples of critical infrastructure. Briefly describe the examples, and explain how they are operated and utilized. Provide any information that you feel is unique to each sector. In your local community, research the infrastructure, and identify one particular element that may be of particular interest to a terrorist or vulnerable to natural or manmade disaster. Are there any protective measures in place to ensure its safety? .

Critical Infrastructure Case Study Power plants are an important part of critical infrastructures and local, state, and national economies. Therefore, power plants need deep and multilayered access controls due to concerns over physical security. There are a number of sensitive areas that must be secured, and various employees need different levels of access to these locations. At a plant in the upper Midwest, this access is handled with identity badges that include images of the user and an RFID with their access rights. The RFID handles access through multiple levels. There is a security checkpoint at the entrance to the parking lot, and at the entrance. Both points require a badge to enter. From there the badge allows personnel to enter the facilities they are authorized to enter. It also acts as "something you have" for multipoint authentication onto secure systems. These are all standard functions for an RFID badge system. The badges also have an automatic deactivation feature, which is useful for certain personnel. Maintenance personnel, for example, do not have enhanced access and do not require access to secured areas of the site. However, the maintenance team may need access to any area of the facility regardless of its sensitivity, in the case of a breakdown or special project. To allow for this, the badges can be granted access rights that decay over time. This allows for temporary access to secure areas that is then automatically revoked over a number of hours or days. This lowers administrative time, and reduces the risk of human error in rights assignment. .

Critical Infrastructure and a Cyberattack Presidential Decision Directive 21 (PDD-21) identifies 16 critical infrastructures. PDD-21 lays out the national policy to maintain secure, functioning and resilient critical infrastructure. Select a critical infrastructure sector from the list below and discuss the impact that a cyberattack could have on that system or service: Communication Sector (voice communications, digital communications, or navigation) Energy Sector (electric power grid) Water and Wastewater Systems Sector (water supply or sewage) Healthcare and Public Health Sector (hospitals) Transportation Systems Sector (rail or air) Financial Services Sector (banking ) It is the third and fourth order effects from the cyberattack on the chosen critical infrastructure that shows the far reaching and devastating effect of a cyberattack. To demonstrate the interconnectedness of critical infrastructure, explain the cascading effects on other critical infrastructure. Then, discuss the measures DHS has taken to ensure resiliency of the selected infrastructure and the measures that need to be implemented in the future. The Critical Infrastructure and a Cyberattack assignment Must be three to four pages in length (excluding the title and reference pages) and formatted according to APA style as outlined in the Ashford Writing Center (Links to an external site.) . Must include a cover page (Links to an external site.) with the following: Title of paper Student’s name Course name and number Instructor’s name Date submitted Must include an introductory paragraph with a succinct thesis statement. The thesis must be in both the introduction and the conclusion. Must use at least three scholarly sources or official government sources in addition to the course text. Must document all sources in APA style (Links to an external site.) as outlined in the Ashford Writing Center. Must include a separate references page that is formatted according to APA style (Links to an external site.) as outlined in the Ashford Writing Center. Carefully review the Grading Rubric (Links to an external site.) for the criteria that will be used to evaluate your assignment. .
