Interactive Television:
Interactive television allows everyone in the family to get aware of all sorts of topic ranging from sports, news to entertainment or distance learning sitting in their own living room, at their own pace and in private. Children can learn to read, get information about various study topics and can find the relevant videos and animations at a click.
Impact of Interactive Television on the privacy:
Interactive television could lead to a loss of privacy.
- In home shopping, the company records credit card details to make transactions which include information about family and the buying habits.
- With this information, the company gets to know income, your preferences and can start sending you advertisements through emails and pamphlets regarding products which you may or may not need.
- Many news channels or entertainment channels may be interested in information about television viewing hours, when television is switched off and what are the peak hours of watching television.
- Hackers can get access to family as well as viewing habits and other confidential details.
- Emails, date of birth, place of living and other private details about the person can be intercepted by the hackers...

1. Explain in detail with examples each of the following fundamental security design principles: economy of mechanism, fail-safe default, complete mediation, open design, separation of privilege, least privilege, least common mechanism, psychological acceptability, isolation, encapsulation, modularity, layering, and least astonishment.
Security in general means the protection of an asset. 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.

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!
