The Future of the Personal Computer

What do you think the future of the personal and business computer will be? Things have moved on at such a pace over the last decade and this is set to continue in the next few years. Competition is as fierce is ever with the computer companies thinking of new interesting ideas to offer to the market on a monthly basis. In this article I will be giving my opinions on the future of computers.

I have owned a personal computer for the last eleven years. We now have one main computer and two laptops in our household. My fourteen year old step-daughter spends a great deal of time on her laptop. She completes her homework and sources information on the internet. She also enjoys communicating with her friends on sites like facebook, msn messenger and myspace.

I have a number of websites and also promote the sites of other webmasters; I therefore also spend a large amount of my time on the computer.

I was thinking earlier today that I would love to be able to tune into the television on my personal computer. In this day and age I am amazed that this is not available, I think that it will be in the future. I am aware that you are able to buy an add on to make this possible but just think it should be available on all computers as standard. It should be as easy as connecting to the internet.

I think that within the next ten years people will be making the majority of their phone calls via their computers, using a microphone or head phones, they will be watching television on their computers, they will be controlling the lights, heating and other household appliances through their p.c. Basically the computer will be an even more integral part of one's life than it is today, I can not wait for it to happen.

Types of Online Fraud and Scams

There are different types of online fraud and scams. It is best to know about them so that you don't become another countless victim.

* The first is the Phishing scam. Here, a scam artist will pretend to be the financial institution that you have business with and tell you there is a problem. To correct this, you have t fill up certain information in the form that is attached to the email.

* There is also the Nigerian Email Scam where just like the Phishing scam, you are sent a message saying that somebody there has millions of dollars and needs help getting it out of the country. In exchange for your help, you are promised to get a certain percentage of the wealth.

* Another example is when you decide to put a certain item up for sale through a website. The scam artist tells you they are interested in the item and they are willing to pay for this but first, you have to send this item to Nigeria.

* The same thing can happen to you when you look at an auction site and find something interesting. When you win the bid, naturally you have to pay for it but when you send the money, the merchandise is never shipped out to you. Just to let you know, the FTC has reported 51,000 auction complaints in 2002.

* Some scam artists pretend that they are in business of preventing credit repair scams or protect you from identity theft when fact they are the ones who are doing the crime. They will send you an email and promise to help once you give them certain information.

* You may also get an email stating that you won an online lottery worth millions of dollars. In order for you to claim it, you have to give some personal data.

There are other kinds of fraud and scams out there aside from those mentioned. Remember the line if it is too good to be true it probably isn't? Well this is what is happening here. When you get an email, it is best call your financial institution or check with the Better Business Bureau. If you want to buy something online, make sure the seller has an address and a contact number so if there are any problems, the item can be returned.

Spam Firewall

What is a Spam Firewall?

A spam firewall is a hardware device that sits between your internet firewall and LAN. It is called a "firewall" because it provides data filtering of email packets, and blocks the packets that meet the criteria of "spam". Spam firewalls can also provide anti-virus protection, anti-spyware, anti-spoofing and anti-phishing services, depending on the model you choose. A spam firewall is not designed to protect your network against intruders such as hackers - you will need a regular internet firewall for that.

How Does a Spam Firewall Appliance Work?

Spam firewalls use a variety of methods for determining what is considered spam and filtering it out. Normally a form of blacklisting is used, which automatically filters out email from known spammy addresses. A whitelist may also be used, which allows the administrator to identify addresses or domains that should never be blocked. Keyword scanning may also be used, allowing the administrator or individual user to block emails containing certain keywords or keyword combinations. A form of message authenticity checking is also normally used to identify valid "from" addresses, check details of the entire SMTP process, or validate legitimate IP addresses. Many spam firewall appliances also use bayesian algorithm filtering, which help the firewall block more spam over time as it "learns" what is considered spam based on message history, user input and other analysis. Incoming message flow filters also look at the number of incoming messages and where they are from, allowing them to quickly spot and stop a sudden barrage of spam emails that have been mass-distributed from the same source. Spam firewalls are very "smart" and good at eliminating the majority of spam email that comes into a network. They are not 100% effective, but many come close.

Are Spam Firewalls Expensive?

Spam firewall appliances range in price from around $2000 up to $20,000 or more, depending on the number of users it needs to protect and features. Many spam firewalls have optional features like antivirus or anti spyware. Spam firewalls need to be kept up to date with the latest data on known spam sites, new algorithms, updated filters, etc... This is normally handled by the firewall manufacturer as an auto-update feature. As with most network appliances, an annual maintenance plan is usually purchased for the purpose of keeping the firewall up to date and performing it's best.

What About False Positives?

Spam firewall appliances use many sophisticated techniques to identify and block spam, generally with very good success. Because spammers are constantly change their techniques in order to get their junk mail past the latest and greatest spam filtering technologies, spam firewalls must continually monitor patterns and make filtering corrections. Spam firewall manufacturers are also constantly make corrective configuration changes to keep up with the battle against spammers. For this reason, even the best spam firewall is going to filter out "good" mail from time to time. This is called a "false positive", and administrators (and users) must always be on the lookout for this. Most spam firewalls have sensitivity thresholds that can be adjusted by an administrator to help overcome false positives.

A spam firewall appliance is not your typical "set it and forget it" firewall, but the advantage of having such an appliance on your network far outweighs the need for some administrative work. If your organization experiences a lot of spam mail - get a spam firewall and experience the difference!
