Students will develop privacy policy and protocols for a highly regulated organization in the United States that will have a mix of remote, work from home, and multiple business offices. The privacy policy will need to address all work locations in support of the privacy of confidential information. Consider elements such as shared workspaces in the home and workplace, printing, telephone conversations, use or personal devices (computers and phones), access to the internet, etc.

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).

1. One  of the advance features I have learned using Microsoft word is the  insert feature. Being able to place all sorts of symbols, pictures,  graphs to a word document helps make it stand out more. For example, if I  were to write a document that talks about graphs and data, I can insert  a chart to properly displays the numbers I want to present over just  regular text. To do so, you must click on the Insert ribbon right next  to Home, under the Illustrations tab, you will see the Chart option.  Another window will open showing you the many different types of charts  and graphs that you can use to present your data. After selecting the  chart you want to use, the image will be inserted into the document  along with another window that reads Chart in Microsoft Windows. It is a  spreadsheet that you can use to enter the data you would like your  chart to display.

2.  An advanced feature that I learned in Microsoft Word was to insert a  picture. This may not be advanced to others but was a feature I had to  play with to insert correctly. To perform this task you would open  Microsoft word and open a blank document. Once the document is opened  use the tab on top that states insert, once you tap insert you have  options to use picture on device or online pictures. I chose online  pictures which provides more options. To use the online search you can  type whatever your looking for in search engine. Once you select the  picture you want to use on your document click picture and below will  provide option to insert. After tapping insert picture will drop onto  document. The picture on document will then need to be positioned by  clicking on picture and dropping on document where desired. Once picture  is positioned use arrow keys to adjust size of picture as desired. I  find this a great feature and think an added illustration always  enhances a document of any kind.
