10) In what ways can a computer security protect the privacy of individuals? in what ways can computer security threaten the privacy of individuals?

computer security is the prime way to protect the individual from crime via the web and computer. Fire walls and antivirus are some ways that the individual can protect themselves on a computer, it gives the individual privacy because hackers wont be able to access their privet information. biometrics is a way of computer security but yet it is an invasion of privacy, because the computer now knows all of your personal information about you from your finger prints and eye scans.

11) What are smart weapons? how do they differ from conventional weapons? what are the advantages and risks of smart weapons?

missiles that use computerized guidance systems to locate their targets. its different because you can control where the missile goes, and have really accurate results. theoretically it should lower the amount of people killed in war, but it reduces the amount of time people have to make those important life-death decisions "should i blow this up or not?"

7) bugs and breakdowns. bugs are just failure of hardware components. and break downs happened because of glitches in the system.

8) physical access restrictions such as biometrics which scans body parts to verify your ID. Passwords help make sure no one steals your information. Firewalls keep the internal networks secure while enabling communication with the rest of the Internet. encryption protects because it scrambles the transmissions.

NOTES

Security and Reliability:

A bigger problem them criminal activity on the computer is Glitches in soft wear and bugs.
some examples:
*Once in the county of LA, the system at a Medical Center broke down, and it really showed the doctors and others that they rely too much on the computers because they didn't know what to do.
* another was a mars space orbiter. Right before it was about to land, it burned out due to glitches from mixing up English and metric units.

* a glitch in the computer accidentally charged cellphone users 600$ a min. one user was charged $57,346!

*2003: Japanese air traffic control failed and they had to communicate BY PHONE!

*all flights got canceled one Christmas for Delta air lines b/c the computer couldn't handle the number of flights being delayed by the weather.

the most famous bug was known as the Y2K bug. it was thought that as soon as it became 2000, before the millennium computer programmers made software to change only the last 2 digits because the first 2 were always "19" but when it became "20" many computers became unstable. some even stocked up on food and water prepared for the worst in case the economy (ran by computers) collapsed.

1. it is impossible to get rid of ALL bugs.
2.dangerous bugs are hard to spot
3. the bigger the system the bigger the problems

2. Why is it hard to estimate the extent of computer crime?

its is hard because the source and amount of crime is hard to track on the Internet, and a lot of it goes undetected and unreported.

4. What is the most common computer crime? Who commits it? what is being done to stop it?

theft of information, finical fraud and theft of passwords. Most of the people who do this are company insiders (on their own company!). the people are clerks, cashiers, programmers, computer operators and some managers. Internet security can help prevent this from happening.

Social and ethical issues of etiquette rules for appropriate behavior while on the internet

The internet world is a large world, perhaps relatively close in size to the “real world”. and with any great system, there must be guiding rules to maintain social order. Though the rules for appropriate behavior while on the internet is not specified, there are a set of unwritten rules, or common rules that most humans have ingrained in there subconscious. The first is respect for other views, cultures, and ideas. Second is security, by securing the information you share and not plagiarizing. And last is having Honesty and integrity in all your actions.

When entering the internet realm it is essential to understand that people form all different parts of the world, and people with entirely different views are online as well. It is important to understand the internets globalization and cultural diversity, and work with--or around--any differences that you may have with someone. There are billions of people in the world, chances are not everyone is going to agree completely with your views. Be flexible and open minded. Attacking the opposing party will only further illuminate the giant fallacy of the internet which is ignorance to online interaction.

Internet Security is an important component in understanding and creating a friendlier and more productive internet. Not only is it important to make sure your own work is secure, but you must beware of plagiarizing any other work. Plagiarizing is a threat to someone’s intellectual property. By using their ideas, your are stealing the most precious possession that one has; their mind. avoid “copying and pasting” works, and if you do make sure to have references to the original author.

The last point, and maybe the most important point is integrity. Most everyone is instill with values like, “don’t steal” “don’t lie”, “don’t cheat, then why so, are some able to do it behind a screen? One must understand that integrity should be there, on or offline. The common cortices that we learn in the “real world” should also apply to the virtual world. The don’t lie, don’t cheat, and don’t steal apply to the internet as well.

Internet behavior is essential for a smooth-running internet. Without these unwritten rules, the web will result in mayhem. Stick to the rules and enjoin in what is right and forbid what is evil, so if you see one who doesn’t show internet etiquette, be quick to correct him/her.
