...2. Select a standard used to share data among different health information systems and explain how it works, tell when it became a standard, and identify the standard's authorizing body. Use of at least one resource other than the course materials is required. (20 points) With the advent of EHR implementation, of the problem that developed what that with so much different systems and vendors can they system communicate and share data with each other. The solution was to have standards. In healthcare information technology (HIT), standards provide a common language and set of expectations that enable interoperability between systems and/or devices. The standard allows data to be shared between clinician, lab, hospital, pharmacy, and patient regardless of application or application vendor. This was necessary in order to meet the goal to improve healthcare delivery. Public Health Data Standard Consortium website describes Information Exchanges Standards define as a structure and syntax of the electronic communication, and is regarded as the standard means by which to send and receive information. The website indicated that there are two information exchange standards; message-based, and a document-based. The site identified the HL7 V3 Clinical Document Architecture (CDA) as one of the main standard. It is one of many standards that are accredited by the American National Standards Institute (ANSI), Standards Developing Organizations (SDOs) to operate in the healthcare arena...

...1. What protocols are used for incoming and outgoing mail when using an email client? There are a lot of initials here. What do the initials stand for and how does each one briefly function? 1. SMTP or simple mail transfer protocol is the directions given to mail in order to reach the server you have intended it to go to. SMTP determines its travel path based on an email address account name and the email server that is being used. If all information is correct your email will reach its destination, if wrong most clients will notify you of the bad email path. 2. IMAP or internet message access protocol is used when retrieving mail that has been delivered to and stored on your client server. IMAP allows you to access your email client’s server to retrieve your held mail upon request. 3. POP3 or post office protocol, is another way to retrieve your mail from a client’s server. However, this method allows you to download all your mail and have access to the mail you have downloaded offline. 2. Browser based email. What protocol does it use? What are its advantage and disadvantage? Pros: Browser based are accessed on HTTP and HTTPS, the “S” means that during communication with the site, it codes your communication making it more difficult for a hacker to steal information in the communication line between you and the client. Web based emails use STMP and IMAP for all interactions. POP3 is not an option since your interactions are based on the web and not in software or...

...First, I should be able to collect evidence-based research that can guide PPE protocols for HCWs exposed to contaminated body fluids and reduce contamination rates across different healthcare settings. Second, the knowledge can improve my practice as a nurse in emergency units. Third, I can propose the protocols at work and decrease the research-practice gap, which refers to the difference between what evidence-based research is saying and ongoing healthcare practices (Rafferty & Traynor, 1999). Finally, as a nurse practitioner, I will find personal and professional gratification that I have fulfilled Standard 13, Evidence-based Practice and Research, through identifying and answering questions in the healthcare setting through nursing research and applying current evidence-based knowledge, including research findings, to guide practice (American Nurses Association,...

...Summary Notes Stew reported that the wireless network in the office was very slow. He requested that we determine if there was firmware available for the SonicWALL, which is acting as the wireless access point. He stated that he needed to have it corrected even if the SonicWALL needed to be replaced. Found that there were no new firmware updates for the SonicWALL, but it was not near the end of life. Recommended adding a wireless device to provide wireless connection, then disable wireless on the SonicWALL. Stew agreed. Escalated to onsite and dispatched a technician with an EnGenius ECB 350 access point. "Danielle reported that she was unable to connect to her work computer from home. Connected remotely to her work computer. Found that the external IP Address had changed. Provided Danielle with the new IP Address and verified that she was able to connect. Documented the change.

...The Master has to take care of the failure of the tablet server. In case the tablet server loses its exclusive lock, it sends a request for the same to the master. The master then tries to find out the reason for the loss of the lock. It might have happened due to termination of the tablet server too. In such a case the master decides on killing the tablet server and adding to the list of unassigned tablets. This tablet again becomes available for future use. The master can terminate itself too, after the chubby session expires. As mentioned earlier, this is one more of the trait of the system which makes it self-sustaining and self-reliable. Networking failures are also avoided by this function of the master. During the start of the system, the master is very much similar to a blank slate. It needs to acquire a complete knowledge of the entire system and the extent to which it can spread or expand. This it has to take a few steps at the start, prior to the execution of the addressing. - Similar to the lock of the tablet servers, the master acquires a lock which prevents duplication instantiations of the master. - It gains a knowledge of the active servers in the chubby, so that it can have a list of the same. - As an extension of the above the master finds the number of tablets that are already assigned to a server, so as to get an information about the remaining capacity of each server. - The master also iterates through the list of tablets to find out which of them have been...

...must have contacted this node previously or have received a message from other nodes. • The routing table structure is modified to store the trust value for each entry of source to destination when receiving a positive of a node that is not a selfish node. From the receiver point of view a perfect malicious node will always provide wrong information. In this case, the malicious node, in order to send wrong information must know the state of each node. • AODV sends request to update the routing path at regular intervals. Hence, at regular intervals, source node is going to have multiple paths each with its trust value from which one with the maximum trust is selected it can transmit this information to it so, from that moment on, both nodes store information about this positive (or negative) detections. Therefore, a node can become aware about selfish nodes directly (using its watchdog) or indirectly, through the collaborative trans-mission of information that is provided by other nodes. • A node detects a selfish node using its watchdog, it is marked as a positive, and if it is detected as a non selfish node, it is marked as a negative. The method to handle RREP packet is changed to update the route entry when new path is received with greater trust than current trust value to send RREQ packet to destination every time thereby disabling the mechanism to initiate RREP packet at intermediate nodes. Behavior of malicious nodes is modeled from the receiver perspective, which...

...is the goal and their next target is the top of rack switch. This type of organization maintains dozens of racks or more should pay attention to what these big cloud players are doing. The potential exists for significant savings as SDN allows data centers to move away from single source hardware to the commodity based pricing we see with servers. The second factor to consider is the size of an organization’s network; which indicates data center with near or above 1,000 active IP addresses as a candidate for SDN. This is true majorly for those addresses that are assigned to virtual machines. The controllers will become a new line item in the IT budget to expect virtual machine vendors to control the switch, rack, and core as the single unit with their software....

...The size of those formats are: PNG 3kb, GIF 2kb and JPEG 6kb. From this pictures we can tell that jpeg has a lot of extra pixels around the letters which requires more space than the other formats. We can tell that this would be very useful if this was a photograph which has high resolution but for our purpose it makes things look messy and on top of that requires a lot of space. There is no noncable difference between png and gif apart from the size. So best choice is to go with gif just because it requires 1kb less of space. There are two protocols used to send data over that provide confidentiality, integrity and authenticity over network connection. I had to choose one of those to make my connection with google servers. So I done a research on those two protocols to make an informative decision which better suits my needs. The way both of them work is very similar they both check servers certificate to make sure the server is who it is advertising itself to be. What happens is you compare the servers certificate to certificate provided by the certificate agency if they match the server is legit. First when making the connection both client and server encrypt using the asymmetric connection and using this encryption they send a key to establish symmetric connection. This is done so that the connection is faster because symmetric encryption is quicker then asymmetric. We couldn’t start off with symmetric because both the client and server didn’t have a common key. After doing...

...Following are the Servers which have been used; 1. Web server. 2. Email server. 3. DNS server. 4. VPN server. Web server A computer, including software package that provides a specific kind of service to client software running on other computers. A Web server is a server-based product that returns files to clients when requested. These files are typically returned in the form of Web pages to a client internet browser. Most of the web servers are built for the java community, and some are open source like Apache. A web server handles the HTTP protocol. When a request comes into the Web server, the Web server simply passes the request to the program able to handle it. The server side program usually provides for itself such functions as transaction processing, database connectivity, and messaging. Email server Email server works as a postal address an email address specifies the destination of an electronic message. An internet email address looks like this: user name@domain name. This user name is a unique name that identifies the recipient. The domain name is the address. Many people can share the same domain name. Anyone can send a message anytime, anywhere. You can send the same message to several people at the same time. You can forward information to co-workers without retyping it. You can save time. Email is fast, usually taking no more than a few minutes to be received. You can email electronic documents and the recipients can then edit and return revised versions....

...open source version of control system which manages files and directories over time. All the files are placed in the repository which is like an ordinary file server except the fact that it remembers every change made to the files and the directories. There are sets of commands used for SVN checkout, SVN add, SVN delete, SVN delete, SVN status, SVN commit and others. Here we are just going to talk about SVN commit. SVN Commit: The SVN commit command sends whatever changes you have made to the file to the SVN server. Whenever the SVN commit command is issued it will change the added and deleted files. In other words, the SVN commit command actually executes the file to make it permanent. Question No. #7: Briefly explain an application of cryptographic hash function? Answer No. #7: Hash function means a function that compresses arbitrary input (strings, numbers, characters) and converting into the shorter fixed output such that it is unlikely to be same even if the input are similar. This function ensures that the value repetition is infeasible even if there is just a letter difference ensuring data integrity. Cryptographic hash function is used create public key fingerprint, verifying integrity of larger downloads, verifying password and others. The most commonly used cryptographic hash functions are SHA-1 and SHA-2. Question No. #8: Research and briefly discuss privacy implications of using the popular app SnapChat.

...NT1330 Unit 7. Exercise 1. AD OU Planning Scenario Review the following scenario: As an IT Administrator, you have been tasked with designing an Active Directory Domain Organizational Unit Structure for a new AD implementation at an existing organization. You are scheduled to meet with the management team and need to formulate a list of questions you will need answered in order to recommend an OU Structure appropriate to the organization. Develop a list of 5-10 questions to guide your design plan. 1.) How is the existing structure of the organization? 2.) How many departments will there be? 3.) How many sub-departments will be needed? These questions will help in documenting the existing structure of the organization so as to divide the administrative tasks into categories and document the administrators who are responsible for each category. Also, these will define the hierarchy of authority in the directory as well as what departments the company will have. 4.) What are the company’s physical/geographical sites? This will address the issue of different geographical divisions which will probably have different computer management needs. The design will be based on management of resources, users and geographical boundaries. This will make the administration easier. 5.) How many OUs will be needed within each Parent OU? 6.) Will departments need to share resources? 7.) What resources are required by each department? 8.) What group policies to be implemented and who’s...
