A security system implementation company is contacted by DLD lab, for the implementation of authentication system so that BEE-2 students can get lab access. The system will utilize RFID based university card scanner, password entry and verification mechanism and a fingerprint scanner. The system should work as follows: the student should get its RFID card scanned by the system. If scanning is done successful (valid) then the system will ask you to provide password. Along successful scanning and a valid password, the access is granted. If in any case the above verification is avoided, then the student is required to pass through fingerprint scanning. Only on matched fingerprint, the student is granted access. LA=F (FP, PW, RFID) Where FP: fingerprint PW: password entry RFID: RFID scanner LA: lab access a) Compute the truth table for the system b) Using part(a) write the system Boolean function c) Simplify the system to minimum number of gates using K-map d) Design the system obtained in part (c ) using NAND gate only

Let's suppose a company has hired you as a security engineer and that company asks you to work on a project. This project targets to prevent COVID-19 as it is the biggest pandemic for a number of reasons. It's a kind of virus, meaning no one has immunity. The company wants you to work with the team in this project where you are required to take care of the security parameters of "Corona-Watch". It can behave as a substitute to alert a person if he/she might have been exposed to the coronavirus. It uses private, local Bluetooth signals to help a person take action. Based on his/her anonymous logs it will provide a POTENTIAL RISK report: Monitor Symptoms Isolate from others Rest and take care Get tested Refer to medical agencies if advised a. As the data is logging so how would you promote database security in context of this project?Illustrate b. Is modification attack possible in this scenario? If yes then at which level it would impact (i.e. high, low or moderate)? Support your answer…
Is there a specific goal in mind while designing the authentication process, or is it more generic? Find out the positives and negatives of the many authentication methods that are available, then evaluate and contrast them.
Create a made-up scenario involving the administration of login credentials and explain it in detail. Find more about the different authentication techniques. Although a login and password are required, do you think they will always be necessary?

One of the four methods of access control might be used in this scenario. What drew you to one above the rest?
A SAF authorization form is used in most universities to approve funding for students to aid their studies. Suppose a student fills out a blank form and sends it to his or her departmental chairperson for a signature. If the amount of funds requested by the student is small (under 10,000 Tk), then the chairperson signs the form and routes it to accounts payable to be input into the accounting system. The system cuts a check that is sent to the student for the right amount, and after the check is cashed, the form is filed away with the canceled check. If the check is not cashed within 30 days, the form expires. When the amount of the requested fund is large (over 10,000 Tk), the chairperson signs the form and sends it to the chief financial officer along with a paragraph explaining the reason for the grant, and the chief financial officer will sign the form and pass it along to accounts payable. Both the chairperson and the chief financial officer can reject the SAF authorization form…
