What Game websites are not blocked by employers?
That all depends on your employer. Some employers block a lot of websites and some block very few. I would suggest that you try several different sites and see if one works.
Another suggestion is to use google image search to figure out which sites are blocked and which are not. For instance, if you want to play Castle Wars, go to Google Images, search for Castle Wars and then see which images come through. If a site is blocked you will not be able to see the image.
WARNING: There is a reason why your employer blocks game websites. If you decide that you want to play games at work, keep in mind that you may lose your job. There may be no one looking over your shoulder but there is certainly someone who blocked the site in the first place and might figure it out.
I have been through similar problems but my problem was at school.... the website i am about to tell you about sounds super cheese.... and you may be like no way.... but coolmathgames is a really fun website and suprisingly doesn't have much to do with math :)

What is secure online transaction models in e-payment?
Secure online transaction models
-The simplest method of doing direct business online on Internet is to set up a secure world wide web server then create content pages and program forms to take orders.
Secure web servers
A secure web server must by definition support some type of security protocol. The two most important are secure hypertext transfer protocol (S-HTTP) and secure sockets layer (SSL), which was initially developed by Netscape and offered to the Internet community as a proposed standard in 1995. However, one of their primary advantages is their relative unobtrusiveness to the consumer using an SSL or S-HTTP enabled browser.
Secure server purchasing
The consumer browses through graphical and textual descriptions of the merchants' products selects a purchase and usually clicks on a button that says "buy now" to make a purchase. If consumer is using a secure browser supported by secure server, that button will produce a form on consumer's screen which the consumer must complete. Delivery and payment information has been provided the product will be delivered. If the customer is using a browser that is not secure or that uses a protocol not supported by the server, then some other method must be employed to consummate the transaction. Delivery information represents name, address, delivery address, email address and any other information necessary to deliver the product.
If product is a physical item, then a physical destination, preferred shipper and telephone number may be necessary.If product is a digital item, then it may be transmitted directly to consumer via the browser by e-mail or through some other application such as file transfer.
Secure server selling
- First the merchant needs to publish product offerings on Internet with secure server. Servers are available that support SSL, S-HTTP and both. Because the Internet is an open network based strictly on proper and widespread implementation of standards, it doesn't make sense for merchants to limit their potential customers by using only one standard.
The merchant must go beyond merely setting up the server. As with mail orders there must be a mechanism for processing the information contained on an order form. Most often the merchant will use interfaces of some type to automate transactions. Companies selling physical products over Internet use email confirmations and shipping notices to keep customers up to date on status of orders and all merchants can use network applications to notify their internal organization of orders.
What are some security issues concerning eCommerce?
E-commerce is defined as the buying and selling of products or services over electronic systems such as the Internet and to a lesser extent, other computer networks. It is generally regarded as the sales and commercial function of e Business. There has been a massive increase in the level of trade conducted electronically since the widespread penetration of the Internet. A wide variety of commerce is conducted via eCommerce, including electronic funds transfer, supply chain management, Internet marketing, online transaction processing, electronic data interchange (EDI), inventory management systems, and automated data collection systems.
Privacy,integrity & authenticity is the major issue of e commerce.

How do schools and in particular C2K block websites ie how do they find them?
I believe they have people monitoring the network for Google searches and websites that are accessed. When they find a site they don't like, they add it to the database and BAM! new blocked sites,
EDIT: I have done lots of research on this using C2K and have found out that they have a system which scans a webpage for a banned word in their data base and if its there they block the page. They don't block the whole website, only the pages containing the banned words. I used all my research to make a website which is invisible to school servers and is almost impossible to block.

What are the two protocols that an email recipient's email server uses to deliver a message?
SMTP Server
SMTP stands for 'Simple Mail Transfer Protocol'. A protocol is an algorithm or procedure of communication, for a particular purpose. This server program exclusively handles the sending part of a mail. When you login to your mail account through a mail client like, outlook express or access directly through a site like hotmail, your client computer communicates with the SMTP server of your email site. An email id is by default in the format 'username@mailsite.com'.
The SMTP server receives the sent mail through port 25. Different ports of a server machine are assigned for certain specific tasks. Then the SMTP server separates the user name and the site name. If the site name is the same as the mail site from which it is sent, then it forwads the mail to its POP3 or IMAP server, which handles incoming mail. For example, if I am sending the mail from my gmail account and the recipient's address is also a gmail account then the gmail SMTP server will simply forward the mail to the POP3 or IMAP gmail server.
If on the other hand, the sent email id belongs to a different site like yahoomail then the gmail SMTP server will contact the DNS (Domain name server) and ask for the IP addresses of the yahoomail server and forward the mail to the yahoomail SMTP server. A mail is a text file which is then forwarded by the yahoomail SMTP server to its POP3 or IMAP server. This server stores it into a particular file dedicated to the recipient's mail account.
Many a times it happens that the SMTP server cannot locate the IP address of the mail recipient server. In such cases, the sent mail is queued and periodically sent again. In case its not able to send the mail, the SMTP server generates a 'mailer daemon' message which informs the sender of failure in message delivery and the reasons for the failure.
POP3 and IMAP Server
The POP3 server handles the other end of the emailing job. POP stands for 'Post Office protocol'. Through the server port 110, the POP3 server receives your request for reading mail after you log in.Gmail's POP3 server, maintains a detailed text file for every account that is registered on it. All the mail messages delivered through the SMTP server communication are pasted in that text file, one after the other along with all the required delivery timing and other details. When you want to read the mail, it analyzes the text file and separates each mail by header, subject and sender's name and serves it on your machine. The only disadvantage of a POP3 server is that once you download all your incoming messages through a mail client, they do not remain on the server machine. That is, they are erased from there.
The IMAP (Internet Message Access Protocol) server is an improvement of POP3 server and takes care of the only disadvantage it has. What it does is, it maintains the original copy of your incoming mail text file on the server, even after you download it. So with an IMAP server, you can access your mail from any machine and download the mails on the machine or read them live on the site itself, without downloading.

What is the difference between an Intrusion Detection Utility and a Firewall?
Intrusion detection is a complementary security technology that attempts to analyze and identify any malicious traffic directed against your network. A firewall helps to screen out many kinds of malicious Internet traffic before it reaches your computer.but not detect all types of security attacks.
If you are using an auto fill on a shared computer or in a cyber cafe this would be unsafe it you allow it to remember your user name and password
What types of computer crime do firewalls protect against?
can anyone tell me? What types of computer crime do firewalls protect against
Firewalls are to PROTECT your privacy. They keep other computers from contacting yours without your permission and sending viruses to it or accessing private information on your computer.
What is security planning in computer security?
Security planning for IT may involve the development of security policies (ie, acceptable use, disaster recovery, breach notification), implementation of security controls (to include hardware, software, and personnel), risk assessment, cryptographic use and controls, and legal/ethical considerations. It is essentially the strategic view of computer security as opposed to the tactical view that an intrusion detection analyst might have.
How do you block the sites using firewall?
If you are going to answer a question, at least make an intelligent guess! If you have a new computer, with some relatively recent software, chances are that the firewall ports (optional holes in the firewall) can be configured to your liking. Like I said, if it is recent, but if it's not it could be difficult, or eve if it is actually recent, it still might be a pain. Ask a professional, maybe the Geek Squad (not the Nerd Herd) can help you for a small fee, or maybe someone else for a fee or just for free! i dont know

PS DO not edit the registry unless you know what you are doing . You could permanently damage your computer.
Movable IP address is an IP address which is assigned to an active entity and the same can be assigned to the corresponding standby (redundant) entity when the active entity fails.
I really don't think sites like oDesk are a scam but you do have to be careful when you are dealing with both providers and buyers as well. I personally have had the most success with Elance, the leading online marketplace on the 'net. To date, I have completed over 800+ Elance projects and highly recommend Elance to buyers, experienced freelancers, and newbies too.
The key to succeeding as either a buyer or provider is to be clear about what you need/what you can do and always be willing to communicate and scrutinize buyers/providers before working with them. By doing this, individuals can definitely succeed on sites like Elance, oDesk, etc.
Good luck!

Here are a few best practices I find:
1. Try not to hire someone with less than 100+ hours of odesk experience, let someone else deal with the newbie and train the person.2. Try to find a contractor that is in the same timezone so you can monitor the progress and not wake up realize he went down the wrong path and you are billed 8 hrs.3. If you interviewed someone will good review, insisted on dealing with that account, don't get talked into bait and switch to deal with an unknown account. People with good review cares about their reputation, people doesn't have any review can create a new account.4. Review the work every day and dispute it right away, once it falls outside the disputable window, it will be difficult to dispute.5. Give very detail instructions. Use Skype as much as you can. English comprehension skill is important.6. Ditch the guy if he is not good. It is meant to make your life easier, if you ended up spending more time communicating or getting frustrated, it is not worthed, put up a craiglist ad at your local college. As lot of smart local kids out there.7. Hire from countries that have good average feedback. http://www.odesk.com/community/oconomy Sometimes you get what you pay for in terms of quality, remember, the feedback should already factor in the price, if average feedback is a 3, that means someone really got screw and gave a feedback of 1.
What is stateless packet filtering?
