Spam is sent to promote practically any product or service ranging from “Adult” products to logo design for websites. It is also used by hackers to spread viruses or links to dangerous websites used to gather your personal information like credit card details or passwords for sites like Ebay or PayPal. To the average user these messages appear genuine. Even the link has a genuine looking domain name. This technique is known as “Phishing.”

Here are some smart strategies and tips you can employ now to start reducing Spam and boost your email security.

- Configure your anti virus software to automatically scan your incoming email for viruses. Email is still widely used to distribute malicious software. Make sure you keep your anti virus software definitions up to date.
- If you are someone that frequently signs up for “freebies” or other stuff on the internet start using a separate e-mail account just for this purpose. Accounts from providers like Yahoo!, Hotmail, and Google’s Gmail all come with generous storage as standard.
- If sites don’t accept free e-mail address from the services listed above then use a free disposable email service like Sneakemail – http://www.sneakemail.com.
- If you are posting your email to a blog or your website then submit it in a way that is only recognizable to a human. For example if your email is johndoe@hotmail.com then post it as “johndoe at hotmail.com”.
- Never open a message from an address you do not recognize – always delete it straight away. This is especially so if there is an attachment. Never reply to a message as this only confirms the email address is “live” to the spammers.
- If you get an official looking message from your bank or Ebay or another site you are not sure is genuine here is what you do. Instead of clicking on the link embedded in the mail log on to the site normally via your browser. If there are any genuine serious problems you should get a message when you log on. Alternatively contact the site’s customer service via the phone if possible.
- Consider using standalone spam filtering software. This software analyses your email for common characteristics of spam email including words like “click” or “teens.” It also compares senders’ emails against a “Friends List.”

Having a strategy to deal with email spam and viruses threats is essential for any business to survive and be productive.  You can limit the negative impact to your business by having policies and guidelines in place.

Tips to avoid getting email spam:
<ul>
<li>If you have a company web site, use a contact form that the web site visitor
can fill out. Some spam mers use robots that crawl web pages looking for
email addresses. Your web site designer should be able to help you with this. </li>
<li>When signing up for forums, products and services use a free email or throwaway
account like hotmail or Yahoo mail. </li>
<li>When signing up for offers be careful what boxes you check although technically
not spam you may get a lot of email offers you do not want. </li>
<li>Never reply to an email spam message, this just lets them know that your
account is active. </li>
<li>You may want to use a throwaway email address if you post on newsgroups
or forums. </li>
</ul>These measures may help to reduce spam, but if you have an old email address you may want to change your email address or deploy a spam filter system.  There are several choices for anti spam systems you could buy software that runs locally on your PC to filter the spam, but this can be expensive, does not prevent virus infection, and is not a good choice in a networked environment.  Managing individual machine spam software is inefficient.

If you have limited technical resources you can outsource you email spam filtering to a hosted anti spam and virus solution provider.  Spam filter service providers colocate their spam and virus filters in data centers with redundant power and network connections.  You will need to change your mail exchanger on your dns servers to point to the service providers spam filters. Your service provider will then scrub your email for spam and viruses.  They then forward your email to your mail server minus the spam and viruses.  This gives you a few extra layers of protection.  In the event of a network outage or server downtime your email is held and is delivered when the network or your server is available minus the virus and spam.  Spam filter services also scan for viruses; this adds another layer of defense to the virus software already running on your network.

If you have an organization with more than one hundred email boxes investing in your own spam filter appliance is the most cost effective solution if you have the technical expertise to manage the system.  A spam appliance sits in front of your email server and blocks spam and viruses.  The price of the spam appliance will depend upon your number of users, amount of mail and storage requirements.

Fighting spam is no longer be a losing battle if you have a good strategy to deal with the threat.

One solution to this problem is a filter or a free spam blocker. Many companies have designed filters for their customers. Many e-mail servers, especially the renowned ones that have a reputation to protect, have their own free spam blocker. There are several types of programs that can help you stop spam, including:

- the ones that are offered when you create a new e-mail address. Every company that provides e-mail service has a spam filter, including those that offer free accounts like Hotmail, Yahoo!, Gmail and so forth.

- there are also standalone programs that go through your mail folders regularly and do their best to separate valid e-mail from spam and unwanted mail. The main disadvantage with these free spam blockers is the fact that, when they do their checks, they use quite a large percentage of your computer’s resources and sometimes also of your bandwidth. Before installing this kind of free spam blocker, you’ll need to decide if this is okay with you.

- other types of free spam blockers are the ones that work as plug-ins to other programs like e-mail clients. The disadvantage with this kind of approach is that you need to download all your mail anyway, before the plug-in can do its stuff.

When you decide to use a filter, you must be sure that you update it or install new versions regularly, because marketing researchers working for spammres are continuously developing new ways of ‘fooling’ the filters. Filter makers must keep up by improving their software accordingly.

A free spam blocker works by looking for trigger words or phrases inside the text of the e-mails, and categorizing e-mails on that basis. Nowadays, there are special programs being created that are designed to pass spam through free spam blockers by re-arranging words or using a different language style in the e-mails. This is an unfair marketing strategy, of course, but if you want to be protected against it, you must always have an up-to-date version of your free spam blocker program.

Specialists recommend that you should review your needs and see what kind of filter suits you best. Each approach has its advantages and disadvantages. You must make up your mind whether you want to use the default filter on the e-mail server, or if you want to download all your mail before scanning them, or if you are willing to share your bandwidth with a standalone application. The best way is of course, if you can blend all the programs in one, but that’s not always practicable. Still, it is advisable that you should not remain satisfied with the free spam blocker that your e-mail server provides, because you will probably continue to receive unwanted mail in spite of it. Using a plugin in addition to server-side filters is viewed by many experts as the most effective way of getting rid of spam, considering the trivial effort it takes to set up.

The Internet has given over a billion people, worldwide, a way to instantly find information. The number of threats to a consumer’s security increases as the consumer connects with more computers, companies, and people online. The Federal Trade Commission (“FTC”), the nation’s consumer protection agency, says that all Internet users should understand the importance of online security and should take measures to protect themselves.

Why the Need for Security & How to Protect Yourself

The Computer: Part of a computers sophistication lies in its ability to connect with other computers over the Internet in order to bring you information. When it is connected with other computers, it opens itself up for the transmission of information, which can create vulnerability for the computer.  Hackers can connect to the computer, scan it for open ports, and gain access to unauthorized information about the computer user.

Most computers have an Intrusion Detection System (“IDS”) that monitors the computer for suspicious activity. When suspicious activity is detected, the IDS sends an alert that an intrusion has occurred.

An IDS alone will not protect your computer from incoming hackers and viruses. Computer users also need to protect themselves with firewalls, which create a barrier between hackers and the computer and help to prevent access to unauthorized information.

The Computer User: The computer user can also accidentally open doors that will lead to a security breach, such as when the user is using the Internet to make purchases. According to the U.S. Census Bureau, U.S. e-commerce sales for the year 2007 were $136.4 billion.  Although the Internet has made shopping a whole lot easier, it has also increased the number of instances of identity theft. A study conducted by the US Department of Justice reports that 6.4 million households experienced some kind of identity theft in 2005.  Consumers also open themselves up to increased junk e-mail called SPAM when shopping online.  Thankfully, there are ways to minimize your risk when shopping online.

Be careful where you post your personal email address.  Consumers using the Internet increase their chances of receiving SPAM e-mail each time they provide their e-mail address to make a purchase. As mentioned earlier, hackers can access consumer information by scanning ports that are not secure. Consumers can help protect themselves by only providing information that is necessary when making the purchase.  There are companies designed to help protect consumers from e-commerce identity theft and SPAM.

When providing payment information, consumers should always make sure the site is secure. An easy way to determine whether a site is secure is to look at the web address bar at the top of the screen. The http, which precedes the address, should change to https when checking out on a shopping site. The ‘s’ indicates that the consumer is shopping from a secure page.

Finally, a consumer should avoid using ATM/debit cards to make purchases, as the breach of this information could lead to unauthorized access of the consumer’s bank account information. Use a credit card instead. Most credit card companies will work on behalf of their client, should a hacker steal their credit card information.  In many cases, the consumer will only be responsible for $50 of the transactions.

When a consumer shops wisely on the Internet and acts in conjunction with private Internet security sites and the FTC they will decrease the chances of being one of the six million households affected by identity theft.

So what can be done about it? What antispam procedures and software really work?

Spam filtering software is the first stop in your antispam campaign, but in some ways it’s the easiest to subvert.

What this antispam tool does is tell your e-mail system to look for designated clue words – sex, nude, porn, for example – and to eliminate the messages that contain these clue words. Of course, there are easy ways to get around these antispam tactics. Did you ever see a message that comes through with the word sex spelled s*e*x? Well, that asterisk method has circumvented your spam filter – or the spam filter of your Internet and e-mail provider.

The other problem with this filter is that you could miss legitimate messages. A friend, for instance, who might mail you that she was “sick of porn sites popping up” might have her message deleted because it contained the word porn.

Two upgraded versions of these antispam filtering products are Bayesian and heuristic filters, which try to identify offensive messages through recognition of phrases as objectionable. SpamAssassin by Apache is probably the best known example of heuristic filtering. What these filters are doing that the more basic ones aren’t is looking at the message itself rather than the subject header. Both Bayesian and heuristic filters have an Achilles heel in that they depend for their filtering on frequency. Were a spammer to send a short message it would get past.

To further complicate things by punishing the “good guys,” major Internet service providers started simply considering batch emailing as potential spam. What this did, however, was to disrupt opt-in products such as e-zines and newsletters. So that didn’t work well. The spammers themselves found a way around it anyway. As they sent out their batch messages they inserted a program that produced a variant in each heading. Perhaps a word that didn’t even make sense, but still individualized each message enough to have the batching not appear as batching.

Some non-profit Internet watchdog agencies started keeping lists of the IP addresses of spammers. When these addresses cropped up in mail they were blocked. The way around this for spammers was simple – they changed IP addresses. The result was even worse, in that those addresses then got handed out to completely innocent folks who now had problems sending e-mail. Then the spammers got really aggressive and started creating and distributing viruses allowing them to hijack IP addresses that weren’t on the “spam” lists.

Where the answer seems to lie for many businesses and their sites is to bypass standard email communication altogether and resort to online feedback forms for electronic communication. Which of course doesn’t resolve the antispam issue for private individuals who have no Web site of their own.
