Suppose your computer is responding very slowly to information requests from the Internet. You observe that your network gateway shows high levels of network activity even though you have closed your e-mail client, Web browser, and all other programs that access the Internet.
What types of malwares could cause such symptoms? What steps can you take to check whether malware has gained access to your system? What tools can you use at each step? If you identify malware, what ways might it have entered your system? How can you restore your PC to safe operation, including the special software tools you may use?

- Compare the security services provided by a digital signature (DS) with those of a message authentication code (MAC). Assume that Oscar can observe all messages sent between Rina and Naseem. Oscar has no knowledge of any keys but the public one, in the case of DS. State whether DS and MAC protect against each attack and, if they do, how. The value auth(x) is computed with a DS or a MAC algorithm. In each scenario, assume the message M = x#####auth(x). (Message integrity) Rina has the textual data x = “Transfer $1000 to Mark” to send to Naseem. To ensure the integrity of the data, Rina generates auth(x), forms a message M, and then sends M in cleartext to Naseem. Oscar intercepts the message and replaces “Mark” with “Oscar.” Will Naseem detect this in the case of either DS or MAC? If yes, how will Naseem detect it? If not, why? (Replay) Rina has the textual data x = “Transfer $1000 to Mark” to send to Naseem. To ensure the integrity of the data, Rina generates auth(x), forms a message…arrow_forwardI need to resolve the following....You are trying to convince your boss that your company needs to invest in a license for MS-Project (project management software from Microsoft) before beginning a systems project.

- 3. Problem Description: Define the Circle2D class that contains: Two double data fields named x and y that specify the center of the circle with get methods. • A data field radius with a get method. • A no-arg constructor that creates a default circle with (0, 0) for (x, y) and 1 for radius. • A constructor that creates a circle with the specified x, y, and radius. • A method getArea() that returns the area of the circle. • A method getPerimeter() that returns the perimeter of the circle. • • • A method contains(double x, double y) that returns true if the specified point (x, y) is inside this circle. See Figure (a). A method contains(Circle2D circle) that returns true if the specified circle is inside this circle. See Figure (b).

In the context of computer and network security, explore and explain what assets must be protected within an online university. What the threats are to the security of these assets, and what countermeasures are available to mitigate and protect the organization from such threats. For each of the assets you identify, assign an impact level (low, moderate, or high) for the loss of confidentiality, availability, and integrity. Justify your answers.arrow_forward
- Please include comments and docs comments on the program.

All classes must be created in Animal (5) First, start by building a class that describes an Animal at a Zoo. It should have one private instance variable for the name of the animal, and one for its hunger status (fed or hungry). Add methods for setting and getting the hunger satus variable, along with a getter for the name. Consider how these should be named for code clarity. For instance, using a method called hungry () to make the animal hungry could be used as a setter for the hunger field. The same logic could be applied to when it's being fed: public void feed () { this.fed = true; Furthermore, the getter for the fed variable could be named is Fed as it is more descriptive about what it answers when compared to get Fed. Keep this technique in mind for future class designs. Zoo (10) Now we have the animals designed and ready for building a little Zoo!
