The kind of attack that tricks a server by sending it to a compromised fake site when it tries to access a legitimate site is called a "Man-in-the-Middle" (MitM) attack.

In a MitM attack, an attacker intercepts communication between two parties (in this case, the server and the legitimate website) and impersonates one or both parties in order to gain access to sensitive information or to manipulate the communication for their own purposes. In this case, the attacker sets up a fake site that looks like the legitimate site and intercepts the server's request, redirecting it to the fake site instead.

The fake site can be used to steal sensitive information, such as login credentials or credit card numbers, or to deliver malware to the server. MitM attacks are typically carried out through techniques such as DNS spoofing, IP spoofing, or session hijacking.

The type of attack that tricks a server by sending the server to a compromised fake site when it tries to access a legitimate site is a phishing attack.

Phishing is the fraudulent practice of sending emails or messages to deceive individuals into revealing confidential data such as passwords and credit card numbers. The attacker poses as a trustworthy entity in a phishing attack, which lures users to open a message, click on a link, or download an attachment, which then steals sensitive data from the victim's computer.

Phishing attacks are the most common method for cybercriminals to acquire user data. It is a prevalent technique in ransomware and malware propagation. A phishing attack can be initiated by email, instant messaging, or social media, among other means. Attackers use a variety of tactics to make phishing emails look legitimate, such as displaying real company logos, using authentic-looking domain names, and manipulating URLs to appear genuine.

Answer:

In Object-Oriented Programming (OOP), the focus is given to objects. An object is an instance of a class, and a class is a blueprint or template for creating objects.

In OOP, programs are designed by creating classes that represent real-world entities or concepts, and then creating objects based on those classes. These objects can interact with each other through methods and attributes, which define the behavior and data associated with each object.

OOP also emphasizes encapsulation, which means that data and methods are grouped together in a class, and only the methods that are exposed to the outside world are accessible to other objects. This helps to ensure that data is protected and that the behavior of the object is consistent.

Overall, OOP focuses on creating modular and reusable code that can be easily maintained and extended over time. By focusing on objects, OOP allows programmers to create complex systems that are composed of smaller, more manageable parts.

One of the main differences is that rdt3.0 includes a selective repeat mechanism, which allows the receiver to acknowledge and store out-of-order packets, while rdt2.2 uses a stop-and-wait mechanism, which requires the sender to wait for an acknowledgment before sending the next packet.

To modify the FSM of the receiver side of rdt2.2 to become the FSM of the receiver side of rdt3.0, the following changes can be made:

To implement the publish-subscribe design pattern in the online auction site described in problem 2.31, the Auction and Bid classes should implement the Publisher interface while the User and Administrator classes should implement the Subscriber interface.

To employ the publish-subscribe (observer) design pattern in the design solution for problem 2.31 on the online auction site, follow these steps:

1. Identify the publisher and subscriber classes.
- The classes that should implement the publisher interface are the ones responsible for managing the auction items, such as the Auction class or AuctionManager class. These classes will notify the subscribers (observers) about changes in the auction state, like a new bid or auction ending.
- The classes that should implement the subscriber interface are the ones that need to be informed about the changes in the auction state, such as the Bidder class or AuctionObserver class. These classes will react to the notifications from the publisher and update their data accordingly.

2. Define the Publisher (Subject) interface with methods for adding, removing, and notifying subscribers.
- AddSubscriber method: Allows a subscriber to register for notifications.
- RemoveSubscriber method: Allows a subscriber to unregister from notifications.
- NotifySubscribers method: Notifies all registered subscribers about a change in the auction state.

3. Define the Subscriber (Observer) interface with a method for handling the notification from the publisher.
- Update method: Handles the notifications from the publisher and updates the subscriber's data accordingly.

4. Implement the Publisher interface in the identified classes (Auction or AuctionManager).
- Add subscribers to an internal list when they register through the AddSubscriber method.
- Remove subscribers from the internal list when they unregister through the RemoveSubscriber method.
- Iterate through the list of subscribers and call their Update method when a relevant change occurs in the auction state.

5. Implement the Subscriber interface in the identified classes (Bidder or AuctionObserver).
- In the Update method, update the class's data and perform any necessary actions based on the notification received from the publisher.

The redundancy mode on Catalyst switches that has the effect of the standby module reloading every other module and initializing all supervisor functions is the "RPR+ mode"

.RPR+ is a Cisco technology that can be used in 6500 and 7600 series switches to offer line card protection against failures. It is a high availability mode that makes use of dual supervisor engines to provide redundancy to the network. RPR+ is also known as Enhanced Route Processor Redundancy mode. This mode of redundancy has the advantage of being able to recover quickly and automatically from a catastrophic failure of the primary supervisor engine by allowing the standby supervisor engine to take over the operation of the switch.

This mode works by having the standby supervisor engine loaded with a fully functional copy of the configuration that the active supervisor engine is running. In addition, the standby supervisor engine keeps all the modules in the standby state in order to make sure that they are available to come online if required.In summary, the RPR+ redundancy mode has the effect of the standby module reloading every other module and initializing all supervisor functions on the Catalyst switch.

In C11 values that persist beyond the statement that created them and have names that make them accessible to other statements in the program are called variables.

Variables are essential in programming as they allow us to store, manipulate, and retrieve data throughout the execution of a program. Variables have a specific data type, which determines the kind of data that can be stored in them, such as integers, characters, or floating-point numbers. In C, common data types include int, float, double, and char. When declaring a variable, you must specify its data type, followed by the variable name.

For example, to declare an integer variable named "age," you would write: in age; This statement reserves memory space for an integer value and associates it with the name "age." Once a variable is declared, you can assign values to it and use it in expressions and other statements within the scope of the variable. In C, variables have a specific scope that defines where they can be accessed within the program. The scope can be local or global. Local variables are declared within a function and can only be accessed within that function.

Global variables, on the other hand, are declared outside of any function and can be accessed by all functions in the program. Using variables efficiently allows a program to manage and manipulate data, enabling complex operations and decision-making based on stored information.
