Internet Security and Privacy

DES is a widely-used method of data encryption using a private key that was judged so difficult to break by the U.S. government that it was restricted for exportation to other countries. There are 72,000,000,000,000,000 (72 quadrillion) possible encryption keys that can be used.

For each given message, the key is chosen at random from among this enormous number of keys.

Electronic and digital signatures help to authenticate official records

Electronic records con be authenticated by a signature

Digital signatures are based on Public Key Infrastructure

Basically yes because it is just out there because I mean you can find sites on Google that are completely free and find someone's IP address at the click of a key.

No. At the moment, Gmail only supports AIM.

no can other people please type in if it gave you a virus

change your keyboard

It uses its own technology to pass through all the blocking methods. It is giving a proxy address for us to access internet and it goes through our proxy and gives us the access. I know if you guys do not satisfy with this answer. So dont scold me. If you know the answer please send it to me too. byee. tc.

Well. to tell you the truth i really don't know. i'm just in middle school, but my older sister ( she is in college) told me that it has a virus, so i think the answer is a big YES

There are three ways to do this. 1) Click on the bar that brings up a list of items saved by auto-complete, then, hold your mouse at the top result on that list, hold delete, and it will delete the items on that list, individually. If you want to get rid of a certain cookie, then, just hover the mouse over the cookie, and press delete once. 2) If you want to erase the file history, but still keep auto-complete, then click on the tools menu on the top-right-hand side, and click the top option, Delete Browsing History. It will give you five prompts, to delete Temporary Internet Files, Cookies, a list of websites you've visited, Data that you put into a form, and passwords. If you want to get rid of them all, click delete all at the bottom, if you want to get rid of one or more, but not all of them, erase them individually. If you keep auto-complete on, these will stock up again, but, for now, that will cover your footprints with fresh snow. 3) To get rid of Auto-complete, completely, then, click on the Tools menu in the top-right-hand side, and click Internet Options. Click on the Content Tab, and on the third option down, it presents you with a prompt to stop auto-complete. If you want to activate it again, then just click on it once more, but those old files will still be there, see Option 2 for information on how to delete your file history.

Kevin Mitnick knows a great deal about computers and how they work. He is touted as one of the greatest computer hackers all time. However if you speak with him you'll realize very quickly that that many of us that have even dozed off for a little while about technology are left behind. Kevin Mitnick, "was" a great computer hacker.

It depends on whether the forum stays online and the database remains intact.

Sites like the WaybackMachine keep archives of websites for years. The pages indexed by Google remains in their cache regardless of the availability of the site. It is not really clear how long they keep these cached pages.

What category of virus is it?! How it work? The two top anti-virus names are Norton and Mcafee. Two anti-virus are costly, too.

But about Zone Alam we know little about it. We always welcome the new comer. Check it out, too.

cookies, are text files sent by a server to a web client and could be Web cookies or tracking cookies

If below does not work you can go to Start>Run . Type cmd into the box and hit ENTER. You will be presented with the Command Prompt Window. Type ipconfig and hit ENTER. Take the number after "Default Gateway" and launch your internet browser. In the address bar type that number and hit ENTER. Launch your browser. In the address bar type 192.168.1.1 (the default gateway IP address for Linksys routers).

The virus be undel until time. Less.

Not completely sure if I know what you are asking BUT if you mean "how do you make it where people cannot take photos off of your site" then I have an answer for you...right click protection. You can go to the piczo zone for that, just search for right click protection code and plenty options will show up. BUT also keep in mind that if someone really wants a photo all they have to do is get a screen copy of it. Anyone can do this and so your personal pics are never "safe" on the net.

It's blocked at the provider level, by the ISP, not by the modem itself.

When you go to a blocked site, it asks for a username and password.

These are the same as the PPPoE username and password, that you have to type into the router or network configuration, in order to get internet in the first place.

For example, if you have a Linksys router set to 192.168.1.1:

Set your browser to 192.168.1.1

There, at the Setup page (the first page that comes up), you'll see a drop-down box with PPPoE chosen. Below that, you'll see username and password. Whatever you typed there, is the same as you want to type to get past the filtering.

However, in the PPPoE blank in the router, the username will also include "@XXX"; for getting past the block, omit everything after the "@". For example, in my router, the username is "tehilaeli@Ineto"; to get past the filter, I just type "tehilaeli", minus the "@Ineto".

However, some sites don't give you the option to enter the password; they're completely blocked, period, and even the subscriber whose name is on the Rimon phone bill couldn't get past it, even if (s)he wanted to. This of course makes sense to the subscriber as he is paying to have stuff reliably filtered out and he is not of a mind to have his kids spending their gray cells getting around it.

It's called Server Based Filtering, It's the same as KosherNet.com offers in the US.

Server based filtering is when the filter is located at the ISP's end and the consumer has no access to any connection other then filtered.

Advantages of Structured Programming

One advantage of structured programming is reduced complexity. Modularity allows the programmer to tackle problems in logical fashion. Also, using logical structures ensures that the flow of control is clear.

Another advantage is an increase in productivity. Modularity allows multiple programmers to work on project at the same time. Modules can be re-used many times, which saves time and reduces complexity, but also increases reliability. It is also easier to update or fix the program by replacing individual modules rather than larger amounts of code.

Use a proxy. Google Proxy. Use a proxy. Google Proxy.

You can use a Wireless router, standard wired router, or wired switch or hub. Common vendors are Linksys, Netgear, DLink and they can be found almost anywhere now.

When the application (Client side) knows about the proxy (Configured within the application) this is called explicit proxy.

When it does not know about the proxy (Not configured within the application), this is called transparent proxy. and in this case the traffic has to be redirected somehow to reach the proxy, or the proxy has to be physically installed in the path of the traffic.

The traffic can be redirected to the proxy using a redirection protocol, such as WCCP or Policy based routing.

The Client side application can be a web browser (Example IE or firefox ), Instant messaging client, streaming client, etc....

I meant 2 look up other differences so..... I CAN'T HELP YOU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
