- Define semaphore. Explain how semaphores work. How can these be used to achieve mutual exclusion and condition synchronization.Q: Alice wants to set up a business company that securely deals with her clients. Bob is a potential client that Alice wants to have a good connection. As a security consultant, your job is to devise a plan to establish a secure information exchange. The assumption is made that Alice and Bob already have their public and public keys; (PrivA, PubA) and (PrivB, PubB) respectively, and both of them have exchanged their public key beforehand. Your plan includes comprehensive protocols to secure all messages, according to Alice’s requirements below. Discuss your answers based on Asymmetric Encryption. i) Integrity: Alice and Bob want to make sure that every message sent cannot be forged by anyone. ii) Authenticity: Alice and Bob can verify that messages actually came from them. iii) Confidentiality: Alice exchanges business-related documents with Bob in a way, so that Alice and Bob may open, read or modify the documents.May I ask for part (iii), user -> nonregistered and user -> registered is in which NF? it wasn't clear. The follow up answer was for a different question.

Connecting to a database depends on the type of the target database and the database management system (DBMS). For example, connecting to a SQL Server database is different from connecting to an Oracle database. But both these connections have a few things in common: •They have a connection string •They can be opened•They can be closed•They may have a timeout attribute (so if the connection could not be opened within the timeout, an exception will be thrown).Your job is to represent these commonalities in a base class called DbConnection. This class should have two properties: ConnectionString : stringTimeout : TimeSpanA DbConnection will not be in a valid state if it doesn’t have a connection string. So you need to pass a connection string in the constructor of this class. Also, take into account the scenarios where null or an empty string is sent as the connection string. Make sure to…What are the three overarching approaches that may be used to break a deadlock?
- For the following scenario for a point of sale system, draw the following: • A mail order company that distributes CDs and tapes at discount prices to record club members (tells the purpose of the system). • When an order processing clerk receives an order form, she verifies that the sender is a club member by checking the MEMBER FILE. If the sender is not a member, the clerk returns the order along with a membership application form. • If the customer is a member, the clerk verifies the order item data by checking the ITEM FILE. Then the clerk enters the order data and saves it to the DAILY ORDERS FILE. • At the same time, the clerk also prints an invoice and shipping list for each order, which are forwarded to the ORDER FULFILLMENT DEPARTMENT for processing there.
