 Write an assembly language program that reads move review information from a text file and reports the overall scores for each movie as well as identifying the movie with the highest total score. There are four movie reviewers numbered from 1 to 4. They are submitting reviews for five movies, identified by the letters from “A” through “E”. Reviews are reported by using the letter identifying the movie, the review rating, which is a number from 0 to 100, and the reviewer’s identifying number. For example, to report that movie B was rated a score of 87 by reviewer 3, there will be a line in the text file that looks like this:

B,87,3

The fields within each record are separated from each other by a comma.

Your program must store the movie review scores in a two-dimensional array (4 rows by 5 columns). Each row represents a reviewer. Each column represents a movie. Initialize the array to zeroes and read the movie review information from a file. After reading and processing the whole file, display a report that shows the total score for each movie and the movie that had the highest total score.

Section 9.4 of our textbook discusses two-dimensional arrays. Section 9.4.2 discusses Base-Index Operands and even contains an example of how to calculate a row sum for a two-dimensional array.

Chapter 11 contains an example program named ReadFile.asm that will show you how to prompt the user for a file name, open a file, read its contents, and close the file when you are done. Look in section 11.1.8, Testing the File I/O Procedures.

Each record in a text file is terminated by the two characters, Carriage Return (0Dh) and Line Feed (0Ah).

Assume that you wish to process a text file named “reviews.txt” that is stored on the “C:” drive in the “Data” folder. If you are using a Windows computer, you have two ways to identify the path to the file’s location:

C:/Data/reviews.txt        OR C:\Data\reviews.txt

Double backslash characters () are needed because a single backslash is defined as being the first part of an escape sequence such as newline (n).

This code can be used to load a reviewer’s score into the array of movie reviews:

; Insert score at reviews[rowIndex][colIndex]

mov      edx,rowSize           ; row size in bytes

    mov      eax,rowIndex         ; row index

    mul      edx                   ; row index * row size

    mov      index,eax             ; save row index * row size

    mov      eax,colIndex         ; load col index

    shl      eax,2                 ; eax = colIndex * 4

    add      eax,index             ; eax contains offset

    mov      edx,score             ; edx = reviewer’s score

    mov      ebx,OFFSET reviews   ; array of review scores

    mov      [ebx + eax],edx       ; Store score for movie

Before you begin: review the information provided in this resource: https://www.pic.gov/sites/default/files/RACI%20Chart%20Overview%20v2.pdf

It takes a team of individuals throughout an organization who work together to safeguard the integrity and confidentiality of data resources. But, how does an organization know that it has enough people in the right roles performing the right tasks to ensure that digital assets will be protected from loss or harm?

The RACI matrix is a tool that can be used to outline the various roles and responsibilities required to provide this protection. For this discussion, you will prepare a RACI matrix that outlines roles of key players in the organization who have data protection responsibilities (i.e. asset security and data protection). Your matrix should specifically address executives (C-level), managers, supervisors, employees. The tasks that you should address are: generating information, using information, classifying information, and managing / using / implementing data loss prevention technologies.

After you have completed your chart, write a brief discussion of responsibilities for each role listed in the rows of your chart. Each role should be addressed in a separate paragraph.

Combine your matrix and your narrative descriptions into a briefing paper for a working group that has been charged with reviewing and improving the company’s data classification business processes. Post your paper in the body of your reply to this topic.

Provide in-text citations and references for 3 or more authoritative sources. Put the reference list at the end of your posting. Use a consistent and professional style for your citations and reference list entries. (Hanging indent is NOT required.)

Please read the below discussion posts and provide two responses in 50 to 75 words

Post#1

DNS Failover is designed to operate at the DNS level. That is, the level before a client connects to any of your servers. DNS essentially converts your domain name (e.g.www.example.com) into the IP address of your server. By monitoring applications and altering DNS dynamically so clients are pointed to different IP addresses, you can control traffic fairly easily and expensively. However, DNS failover does have two notable limitations: a) DNS Failover does not fix an outage when a client is already connected to an application. This is because their browser may not query DNS again for quite some time. b) DNS Failover has a TTL cache issue that could take anywhere from 1 to 30 minutes or more for the IP address change to be visible around the world. This is since many ISP’s recursive DNS servers cache longer than required to reduce traffic. “Time is an important component of the Domain Name System (DNS) and the DNS Security Extensions (DNSSEC). DNS caches rely on an absolute notion of time (e.g., “August 8, 2018 at 11:59pm”) to determine how long DNS records can be cached (i.e., their Time To Live (TTL)) and to determine the validity interval of DNSSEC signatures. This is especially interesting for two reasons” (Malhotra, 2019).

DNS Failover has been around for quite some time and is reliable. As a result, the sequential mode is the most popular for e-commerce applications or where back-end databases exist and some type of synchronization step is required before falling back to the primary. The cloud network monitors all of the available servers based on the monitoring criteria you specify via the management GUI and when it detects the primary down, it automatically fails over to the secondary IP (or if the secondary is down, fails over to the tertiary, etc.). In a typical static content scenario, when the primary comes back, it updates DNS again to send traffic to the primary. However, in an application where back-end databases must be synchronized, you can easily disable auto-failback to prevent the primary server from receiving traffic again. “A passive redundancy approach with diversification has been applied to intrusion-tolerant systems (ITSs) that aim to tolerate cyberattacks on a server” (Okamoto, 2017).

The monitoring system will still alert you that it is back online, but you have to manually force it to start receiving traffic again. This allows you to perform whatever tasks are required to ensure that the primary has the latest copy of the database or whatever is required. One critical drawback to using DNS failover in a situation where back-end synchronization is critical is when the primary is only down for a very short period. The short period would be sufficient to trigger a failover, but insufficient so that existing client connections (or new connections where the TTL cache has not expired) permit some clients to still hit the primary site. In this case, both the primary and secondary sites could receive traffic and create completely different databases that are very difficult to synchronize. “A DNS Load Balancer Daemon (LBD) has been developed at CERN as a cost-effective way to balance applications accepting DNS timing dynamics and not requiring persistence” (Reguero Naredo, 2017).

Post#2

            Cloud computing efficiency and security depends on several security concerns related to networks and connectivity. Protecting information system in cloud environment, from threats can be done largely by maintaining secure data traffic. The concepts of Domain Name System failover and Cloud failover come in this context of data traffic security. These two are most popular approaches in cloud security and share some similarities and dissimilarities between each other.

Comparison

            Functionality of DNS and cloud failover depends on the authentication of IP addresses largely. Both the preventive measures in cloud service security find out necessary action to recover from failures such as downtime recovery. Both the solutions need open access to public cloud in order to become active. The monitoring mechanism used in both the systems are almost equal and works in the same way for identification of servers and detection of faults (Naredo & Pardavila, 2017). DNS and Cloud failover are equally capable of delivering fast recovery as soon as within 60 seconds and can change functions automatically based on the requirement scenario.

The differences in cloud and DNS failover starts with the process through which these functions run. DNS finds easiest solution in re-routing of traffic in cases where a particular server fails, and it makes the traffic run through other active servers. A system embedded in the process helps in detecting the active server through a technique known as ‘round-robin’ method. A fault in DNS failover is that it contains the cached data which keeps revolving till one user’s Time to Live (TTL) in the server. “A DNS Load Balancer Daemon (LBD) has been developed at CERN as a cost-effective way to balance applications accepting DNS timing dynamics and not requiring persistence” (Naredo & Pardavila, 2017).

Cloud failover is popular for its accuracy and precision of carrying out the task necessary for sustained uptime. It does not send cached data back frequently. Sessions cared by cloud have better utilization capacities as it allows remote deployment unlike DNS failover where critical applications of a server are interrupted. To sustain through the TTLs, cloud failover uses session-wise load-balancing that proves to be more efficient than round-robin of DNS. Further, DNS failover fails to offer the flexibility due to the pre-determined conditioning that makes it a rigit system. Cloud, however, includes the DNS often for offering optimized result via a permanent proxy IP address. “DNS, being open-source, is less secure and it has no uncommon method for deciding if data has been intercepted while transmission or information of a domain name originates from an approved domain owner or not” (Ansari et. Al., 2020).

Conclusion

As a result of limitations, cloud failover service is costlier than DNS. There are steady improvements identifiable in DNS in global network. Some of the services are also allowing cache-free recovery of server. In spite of the advancements, it is yet to compete equally with cloud failover. On the other hand, cloud has its challenges too. “In spite of Cloud Computing services seem to be very attractive as an alternative to traditional on-premise data centers, there is still some concern about the providers availability” (Goncalves  & Fagotto, 2018).
