- A Communications is a small phone repair shop. The owner, Ahmet, is currently working alone. Ahmet files his repairs on a customer basis and keeps them in a cupboard. Ahmet knows that he needs to switch to an information system because he wants to expand his business. When the customer brings a phone that needs repair, Ahmet detects the problem, records them in the file and gives the customer time and price information. At the beginning of each day, Ahmet checks the repair list, selects and completes the tasks that need to be done that day. When he sees that there is no required part in stock during the repair, he orders the part to the supplier and postpones that repair work to a future date, informing the customer. When the customer comes to pick up the phone that has been repaired, Ahmet issues an invoice and takes the payment from the customer. Once a week, Ahmet checks the stock and orders the decreasing products to the supplier. In order to develop the information system that…A small insurance company has an online application system that allows its customers to interactwith the business (e.g., log claims). Backups of the customers’ details are done on a spreadsheetdocument stored on Google drive. However, anyone who has access to the Google drive link ofthe file can view and modify all the customer details. On the backup, the system administratordoes not have visibility of the modifications made on the file. By analysing the scenario above, use the security design principles to criticise theoperations of the small insurance company and propose any two simple controlsthat could influence a good security program.An is the kind of server in two-tier systems that provides clients with data stored on disc pages. This sort of server is known as an.
- The owner of KFC wants to use a system to record the orders for the hamburgers. KFC accept the orders via phone calls. When registered customers call KFC on the phone, they are asked their phone number. If the customer is not a registered customer, then a new record is created for the customer. When the phone number is typed into a computer, the name, the email address and the address of customer are automatically brought up on the screen. After taking the order, the total, including tax is calculated. Then the order is given to the cook. A receipt is printed. Sometimes, discount coupons are printed so the customer can get a discount. Carriers who make deliveries give customers a copy of the receipt and a coupon (if there is any). Weekly totals are kept for comparison with last month’s performance. 1.Write a summary of business activities for taking an order.. 2. Draw a context-level data flow diagram.. 3. Draw a level-0 data flow diagram..The kind of server in two-tier systems that provides clients with data that is kept on disc pages is known as an. An is the name given to this kind of server.One of the problems with the Internet email system is that sending forged emails is relatively straightforward, i.e., it is easy to send an email with a fake sender/from address. One solution to this problem would be for a domain’s mail servers to digitally sign any email originating from the domain. For this to be useful, the public key would need to be made available to clients to validate the signatures. It is proposed that the public keys of the mail servers will be verified and signed by a certification authority (same as SSL/TLS certificates) and distributed via a standardised URL for the domain, e.g., https://mybusiness.com/email.pubkey. (a) Explain how the client would obtain the public key and validate the email server’s digital signatures. (b) Discuss the problem of trusting the obtained public key and how this solution results in public keys that can/cannot be trusted. (c) Indicate whether you believe this approach could be used to prevent forged emails and explain why it…
- Computer Science C programming Develop a proxy HTTP server that can accept HTTP requests from clients and convert them to HTTPS request to the web server. The HTTP request can be filtered based on an access control list. The requests can be generated by any web client, such as the curl command or a web browser. the proxy converts plain text HTTP requests from a client to HTTPS requests and then returns the responses to the client. Main objective is to create a proxy HTTP server that converts cleartext HTTP requests from clients to HTTPS requests to servers and vice versa for the responsesresponses.This is for operating systems in cmputer science. I got stuck on few questions. Let me know if you need more clairfication. The asnwers are written in regular paragraph text form. For the second question answer it competely and discuss the configuration how the file integrity file influences the configuration of the tool. Let me know if you need more clarification. But the answers can be found by Googling? Questions: 1) Why is logging important? What is its limitation as a security control? What are pros and cons of remote logging (remote access)? 2) What are the advantages and disadvantages of using files integrity checking tool or file integrity monitoring (e.g. trip wire). This is a program which notifies the administrator of any changes to files on a regular basis? Consider issues such as which files you really only want to change rarely, which files may change more often, and which may change often. Discuss how this influences the configuration of the tool, especially as…There are multiple publicly accessible web and application servers in the CSM Tech group. All of your publicly available resources are served through DNS servers. Your public DNS servers, however, are being used to perform recursive lookups for clients that are not part of your business. Recursive requests from internal clients should only be handled by your public DNS servers; iterative inquiries from external sources should be handled by the servers. Are there any more ideas that you'd want to share? Is there anything else I need to know about the solution?
- From a programmer's point of view, if you want to argue that deep access is better than shallow access, you shouldn't just talk about speed.- Consider another carelessly written Web application, which uses a servlet that checks if there was an active session, but does not check if the user is authorized to access that page, instead depending on the fact that a link to the page is shown only to authorized users. What is the risk with this scheme? (There was a real instance where applicants to a college admissions site could, after logging into the Web site, exploit this loophole and view information they were not authorized to see; the unauthorized access was however detected, and those who accessed the information were punished by being denied admission.)Your company has grown significantly, and suddenly there is a significant increase in the usage of file servers. All of the file servers are in close proximity to the clients, and you're adding many more, resulting in a big group of servers. The number of namespace servers has also increased in recent years. Your original setup utilized the default options for the referral ordering mechanism and polling, which were both enabled. What modifications should you think about making?
