1.)
2.)A static IP address is an address that does not change over time unless changed manually. It is used when you need the IP address or network location to remain the same consistently. A Dynamic IP address is an address that keeps on changing. It is mostly used when having a consistent IP address is not necessary.

4.) I believe that everybody should have the right of security on the web especially through email.
5.) I would not mind working in a business where all employees were required to wear active badges. As a matter of fact, in some ways I do. By knowing where all of the employees are located in the building, the employee can be located if they receive an emergency phone call. Also, let's say there is a fire in the building. Security would be able to tell if anyone was trapped inside. I think it's a great idea!
6.) How do the issues raised in the debate over the missile defense system apply to other large software systems? How do you feel about the different issues raised in the debate?
It seems reliably and fair and the issues raised in the debate seems quite fair.

10. Computer security can help protect private information by keeping viruses and other information stealing things out of our computer. But, such virus protection can be carried too far, preventing the computer user from getting any work done.
11. Smart weapons are missiles that use computerized guidance to locate their target. These weapons locate their target without being controlled from a third party. The advantage is that they can be extremely accurate to the target. A risk is that it reduces the amount of time people make to make life and death decisions.

1.Yes I agree with the author's assessment on the widespread of RFID tags.
2. Yes, for that little price tag it would be reliable in using, if i loose any items at my house it would be easier to find.
3.I would most definitely embed an RFID tag in my dogs and cat if that would increase their chance of being returned to me.

7.) computers have two inherent characteristics that leave them open to attack or operating error: A computer will do exactly what it is programmed to do, including revealing sensitive information. Any computer can do only what it is programmed to do.
8.)One way to reduce the risk of security breaches is to make sure that only authorized personnel have access to computer equipment. Depending on the security system, you might be granted access to a computer based on something you have&endash;a key, an ID card with a photo, or a smart card containing digitally encoded identification
something you know&endash;a password, an ID number, a lock combination, or a piece of personal history
something you do&endash;your signature or your typing speed and error patterns
something about you&endash;a voice print, fingerprints, retinal scans, or other measurements of individual body characteristics, known as biometrics

p. 363-366 notes
When Security Threatens Privacy:
*Active badges can simultaneously improve security and threaten privacy by:
*Identifying who enters a door or logs onto a machine
*Finding an employee’s current or earlier location
*Remembering: At the end of the day, an active-badge wearer can get a minute-by-minute printout listing exactly where and with whom he or she has been.
Rules of Safe Computing :
*Share with care.
*Beware of BBS risks.
*Don’t pirate software.
*Disinfect regularly.
*Treat diskettes with care.
*Take your password seriously.
*Lock sensitive data.
*Use backup systems.
*Consider encryption for Internet activities.
*Prepare for the worst.
